In the chapters to follow the main points of a large-scale experiment on intergroup relations are
reported. It was carried out as a part of the research program of the Intergroup Relations
Project at the University of Oklahoma. In this first presentation, sufficient time and facilities were
not available to make use of data contained in recorded tapes and half a dozen short moving
picture reels. Nor was it found feasible to include introductory chapters surveying major
theories on intergroup relations and elaborating on theoretical outlines of the present approach,
which determined the formulation of the hypotheses advanced and the design of the study in
successive stages. These are presented more fully in our Groups in Harmony and Tension
(Harper, 1953), which constituted the initial work unit in the present intergroup relations project.
Therefore, a brief statement of the cardinal considerations that shaped the conception of this
approach to the study of intergroup relations is in order. It is not unfair to say that the major
existing theories fall within two broad categories in terms of the emphasis placed in formulation
of the problem and methods involved.
In one broad category of theories, the problems are expressed in terms of actualities of events
in group relations as they exist in everyday life. On the whole, theories advanced by many
social scientists fall in this broad category. In this concern over actualities the problem is
frequently not stated and discussion not developed in a way that can be tested rigorously. In
the second broad category of theories, problems are stated and analysis carried out in terms of
more rigorous-appearing concepts and units of analysis. Theories coming from psychologists
and social scientists heavily influenced by them fall within this broad category. In this line of
approach, theories are advanced without due regard to actualities, and consequently they are
plagued with serious questions of validity.
The present approach starts with a serious concern over the rise and functioning of actual small
groups in social life. The hypotheses advanced are formulated on the basis of recurrent events
reported in sociological accounts of small groups. Testing these hypotheses under conditions
that appear natural to the subjects has been a theoretical and methodological consideration of
prime importance. Therefore, a great point was made of carrying on observations without the
awareness of subjects that they were being observed and of giving priority to the uninterrupted
and uncluttered flow of interaction under experimentally introduced stimulus conditions. The
techniques of data collection were adapted to the flow of interaction, rather than cluttering or
chopping off interaction for the convenience of the experimenter. This imposed the task of
securing an experimental site which is isolated from outside influences so that results could not
be accounted for primarily in terms of influences other than the experimentally introduced ones
and the interaction on that basis.
In such a natural, life-like interaction situation, there are so many items that can be observed at
a given time that it becomes impossible to observe and report all behavioral events. Therefore,
there is the possibility of being selective in the choice of events to be observed. In testing vital
hypotheses related to intergroup relations, restricting the number of subjects to just a few is not
the proper remedy. Circumscribing the number of reactions of the subjects is no remedy.
Asking the subjects to remain within optimal distance of a microphone and asking them please
to speak one at a time will destroy the very properties of the interaction process in which we are
interested. The dining hall adjacent to the kitchen is not the place conducive to getting the
subjects to cooperate in preparing a meal of their own accord. By trying to eliminate selectivity
through such resorts we would have eliminated at the same time the essential properties of the
very things we set out to study.
(1) One remedy lies in unmistakable recurrences of behavioral trends so that the observer
cannot help observing them even if he tried to ignore them. If these trends are independently
reported by the observers of two different groups, then they serve as a check against each
other. We have secured such checks time and again in this study.
(2) The danger of selectivity can be avoided (without disrupting the flow of interaction) by
having outside observers in crucial problem situations and by having them make, for example,
their own independent status ratings in terms of effective initiative in getting things started and
ads:
done.
(3) The most effective way of checking selectivity is the use of a combination of techniques.
This consists in introducing at a few choice points laboratory-type experiments and sociometric
questions. If the trends obtained through laboratory-type and sociometric checks are in line with
trends obtained through observations, then selectivity of observation need not worry us as far
as the relevant hypotheses and generalizations are concerned. The actual use of observational,
experimental and sociometric techniques in a combined way, whenever feasible without
cluttering the main flow of interaction, has been a major point of emphasis in our study. In our
previous work, the feasibility of using judgmental indices to tap norm formation and intra- and
intergroup attitudes was established in various studies. This series of experiments, whose logic
and techniques were made part-and-parcel of this large-scale experiment, are summarized in a
paper "Toward integrating field work and laboratory in small group research" (to appear in
Small Group Research Issue, American Sociological Review, December, 1954).
The present study has for its background the invaluable experience of the 1949 and 1953
experiments, both carried out under my direction. In 1949 the design (in three stages) went as
far as the end of Stage 2 of this 1954 study, namely in-groups were formed and intergroup
friction was produced experimentally. The 1949 study was jointly sponsored by the Attitude
Change Project of Yale University and the Department of Scientific Research of the American
Jewish Committee, to both of whom grateful acknowledgment is extended. Without the effective
help of Professor Carl I. Hovland this start could not have materialized. The second study was
attempted in 1953 in four successive stages. We succeeded in completing only two stages in
this attempt, which covered the experimental formation of in-groups. The experiment reported
here, as well as other units during the last two years, were carried out with a grant from the
Rockefeller Foundation to the University of Oklahoma, for which we are grateful.
It is a pleasure to note here the active participation of O. J. Harvey during the last four years in
the development of this program of research. Especially his doctoral thesis, entitled, "An
Experimental Investigation of Negative and Positive Relationships between Small Informal
Groups Through Judgmental Indices," constitutes a distinct contribution in demonstrating the
feasibility of using laboratory-type judgmental indices in the study of intergroup attitudes.
Without the untiring and selfless participation of O. J. Harvey, Jack White, William R. Hood, and
Carolyn Sherif the realization of this experiment and the writing of this report would have been
impossible.
This program of research in group relations owes a special debt to the dedication of the
University of Oklahoma and its administrative agencies to making development of social
science one of its distinctive features. The close interest of President George L. Cross in social
science has been a constant source of encouragement and effective support. Professor Lloyd
E. Swearingen, Director of the Research Institute, has cleared our way for smooth sailing
whenever occasion arose. We have turned again and again to the encouragement and unfailing
support of Professor Laurence H. Snyder, Dean of the Graduate College.

Preface -- 1961
The report of this large-scale experiment dealing with factors conducive to conflict and
cooperation between groups was first released in August, 1954 and was sent in multilithed form
to colleagues active in small group research. Since then, it has appeared in condensed form in
books and journals and has been presented in lecture form at various universities and
professional associations.
In view of numerous requests from colleagues engaged in small group research, instructors in
institutions of higher learning, and the interest expressed by colleagues in political science,
economics and social work in the applicability of the concept of superordinate goals to
intergroup problems in their own areas, the original report is being released now with very
minor editorial changes.
Two new chapters have been added in the present volume. Chapter 1 presents a theoretical
background related to small group research and to leads derived from the psychological
laboratory. It was written originally at the request of Professor Fred Strodtbeck of the University
of Chicago, editor for the special issue on small group research of the American Sociological
Review (December, 1954). This chapter summarizes our research program since the mid-
thirties, which was initiated in an attempt to integrate field and laboratory approaches to the
study of social interaction. Chapter 8 was written especially for this release to serve as a
convenient summary of the theoretical and methodological orientation, the plan and procedures
of the experiment, and the main findings, with special emphasis on the reduction of intergroup
conflict through the introduction of a series of superordinate goals.
We are especially indebted to Mrs. Betty Frensley for her alert help in typing and other tasks
connected with the preparation of this volume. Thanks are due Nicholas Pollis and John Reich
for proofreading several chapters.
The experiment could not have been realized without the utmost dedication and concentrated
efforts, beyond the call of duty, of my associates whose names appear with mine on the title
page. However, as the person responsible for the proposal prepared for the Rockefeller
Foundation in 1951 and with final responsibility in the actual conduct of the experiment and
material included in the report, I absolve them from any blame for omissions or commissions in
this presentation.
On this occasion it is a pleasure to acknowledge the understanding support and
encouragement extended by the Social Science Division of the Rockefeller Foundation to this
project on intergroup relations, a research area notably lacking in systematic experimental
studies in spite of its overriding import in the present scheme of human relations.
This preface is being written with a heavy heart. The research program of which this experiment
was an important part lost a great friend by the death of Carl I. Hovland of Yale University in
April, 1961. It was Carl Hovland who, from the very inception of the research project on
intergroup relations in 1947, gave an understanding and insightful ear and an effective hand to
its implementation. The give-and-take with his searching questions, wise counsel and steadfast
friendship through thick and thin will be sorely missed in the continuation of our research
program.

CHAPTER 1
Integrating Field Work and Laboratory in Small Group Research[1]
The study of small groups has become one of the most flourishing areas of research, involving
men in various social sciences and psychology. The influences responsible for the increased
preoccupation with small groups spring both from developments within various academic
disciplines and from agencies instituted for devising practical solutions for immediate
application. Brief mention of influences contributing to the flourishing state of affairs in small
group research will be helpful as orientation:
1. Theoretically and empirically, works of sociologists have historical priority in showing
persistent concern with the topic of small groups (Faris, 1953). Since the early 1920's a definite
research development in sociology related to small groups has been carried on, as represented
by the works of men like Thrasher, Anderson, Clifford Shaw, Zorbaugh, Hiller, and Whyte. In
the recurrent findings reported in this line of research, which was carried out over a period of a
good many years, one cannot help finding crucial leads for a realistic approach to
experimentation in this area.
2. Another of the major instigators of the extraordinary volume of small group research stems
from the practical concern of business and military agencies. A series of studies initiated by
Elton Mayo and his associates at the Harvard Business School in the late 1920's has
proliferated in various institutions, both academic and technological. Another impetus along this
line came from the concern of military agencies for establishing effective techniques for the
assessment of leaders.
3. Another major influence in the development of small [p. 2] group studies comes from
psychological research. Regardless of the theoretical treatment, the results of psychological
experiments almost always showed differential effects on behavior when individuals undertook
an activity in relation to other individuals or even in their presence, as can be ascertained
readily by a glance at Murphy, Murphy, and Newcomb's Experimental Social Psychology. F. H.
Allport's experiments which started around 1915 are illustrative of this point. In the l930's, it
became increasingly evident that social behavior (cooperation - competition, ascendance -
submission, etc.) could not be properly studied when the individual is considered in isolation.
Psychological "trait" theories or personality typologies fell far short in explaining social relations.
Therefore, when Moreno's work appeared in this country in the mid-thirties presenting his
sociometric technique for the study of interpersonal choices and reciprocities among individuals
(i. e., role relations), it quickly found wide application. A few years later Kurt Lewin and his
associates demonstrated the weighty determination of individual behavior by the properties of
group atmosphere. This line of experimentation was the basis of other subsequent studies
coming from the proponents of the Group Dynamics school. Some other major influences
coming from psychology will be mentioned later.
II
Interdisciplinary Cooperation and the Concept of "Levels"
It becomes apparent even from a brief mention of the background that men from various
disciplines contributed to make the study of small groups the going concern that it is today. As
a consequence there is diversity of emphasis in formulating problems and hypotheses, and
diversity in concepts used. This state of affairs has brought about considerable elbow-rubbing
and interdisciplinary bickering among sociologists, psychologists, and anthropologists. In this
process and through critical appraisal of each others' approaches, the interdisciplinary
approach has become a necessity for achieving a rounded picture.
Faced with the task of dealing with both psychological and sociocultural factors in human
relations problems, psychologists have too often yielded to the temptation of improvising their
own "sociologies" in terms of their preferred concepts. Sociologists, on the other hand, have
sometimes engaged in [p. 3] psychological improvisations. While sociological or psychological
improvisation at times proves necessary on the frontiers of a discipline, it is difficult to justify on
topics for which a substantial body of research exists in sociology or in psychology, as the case
may be.
On the whole, interdisciplinary cooperation has usually turned out to mean rallying
psychologists, sociologists, anthropologists, and other social scientists to toss their theories and
concepts into the ring. But, mere juxtaposition of utterances made by psychologists,
sociologists, etc., in the same room or between the covers of the same book does not bring
interdisciplinary cooperation. Nor is interdisciplinary integration possible by laying down
segments from each discipline along the same line -- one yard from psychology, one yard from
sociology, then a foot each from history and economics.
The outlines of an interdisciplinary approach appear more clearly with the realization that
"psychological" and "sociological" signify different levels of analysis. Men studying human
relations are approaching related, similar, or even the same problems at different levels of
analysis, necessitating units and concepts appropriate for dealing with events on that level. If
we are working on the psychological level, our unit of analysis is the individual; hence our
treatment must be in terms of his psychological functioning -- in concepts such as motives,
judging, perceiving, learning, remembering, imagining, etc. If we are working on a sociological
or cultural level, our concepts are in terms of social organization, institutions, value systems,
language, kinship systems, art forms, technology, etc. (Note 1).
The concept of levels holds a fairly obvious but invaluable check on the validity of research
findings. If it is valid, a generalization reached on a topic at one level of analysis is not
contradicted and, in fact, gains support from valid generalizations reached at another level. For
example, the psychologist's findings of differential behavior of an individual when participating
in the activities of his group should be (and are) substantiated by findings on the sociological
level, namely that collective action in a group has properties peculiar to the group. Checking
and cross-checking findings obtained at one level against those obtained at another level on
the same topic will make interdisciplinary cooperation the integrative meeting ground that it
should [p. 4] be.
During the last century in the social sciences and more recently in psychology, the dependence
of sub-units upon the setting or superordinate system of which they are parts has gained
increased attention, especially in view of unrewarding attempts to account for the functioning
system in an additive way. Understanding part processes is possible only through analysis of
their relations within the functioning system, as well as by analysis of unique properties of the
part process itself. Unless knowledge of the superordinate or larger functioning system is
gained first, before tackling the part processes, there is the likelihood of unwarranted
generalizations concerning the parts, and misinterpretation of the true functional significance of
the processes observed.
In this connection, an illustration from Malinowski (1922) is instructive. Malinowski describes the
complex exchange system of the Argonauts of the Western Pacific called the Kula. The
Argonauts themselves "have no knowledge of the total outline of any of their social
structure...Not even the most intelligent native has any clear idea of the Kula as a big,
organized social construction, still less of its sociological functions and implications. If you were
to ask him what the Kula is, he would answer by giving a few details, most likely by giving his
personal experiences and subjective views on the Kula...Not even a partial coherent account
could be obtained. For the integral picture does not exist in his mind; he is in it, and cannot see
the whole from the outside."
This point can be illustrated in relation to small group studies. Since Lewin's experiments in the
1940's comparing lecture and group discussion methods in changing attitudes, various studies
have shown that in the American setting skillfully conducted group discussion in which
members participate is more effective than lecture presentation of the same material. On the
basis of results obtained in the American setting, it would seem that the superiority of group
discussion methods might be universal. That this is not the case is indicated by one of the
studies in the UNESCO project in India (Murphy, 1953). In an attempt to modify caste attitudes
among college students in India using various methods, the greatest changes arose as a result
of a lecture method using emotional appeals. The [p. 5] experimenter wrote: "Contrary to our
original expectation and hypothesis, these young boys do not seem to be in a position to exploit
fully the discussion technique, in bettering their social relationships. Does it indicate that our
boys have got to be used to the democratic ways of discussion and at present prefer to be told
what are the right attitudes rather than to be allowed to talk them out?" Within a social
organization whose values clearly encourage dependence on authority and effectively
discourage settling issues on a give-and-take basis in small sub-units, particular dependencies
may become so much a part of the individual's ego system that group discussion techniques
would be less effective than methods more in harmony with the social organization in which
they take place.
Such comparative results illustrate the value of starting first with due consideration of the
sociocultural setting with its organization and values before generalizations are made about
small groups functioning as parts of that setting (cf. Whyte, 1951; Arensberg, 1951). For small
groups are not closed systems, especially in highly complex and differentiated societies such
as the United States.
Facts obtained concerning the group setting are in terms of concepts and units at the social or
cultural level of analysis. They will not give the step-by-step analysis of the particular interaction
process; they will not be adequate for the task of dealing with interpersonal relations or the
behavior of particular individual members. At this point, psychological concepts are needed for
a detailed analysis of reciprocal relations, for handling motives, perceptions, judgments, etc.
III
Experimental Steps toward Integration
The rest of the Chapter will be devoted to a summary statement of the prior attempts on our
part toward pulling together some relevant findings in sociology and in psychology in the study
of small groups. In these attempts the guiding considerations have been the following:
1. To extract some minimum generalizations from the sociological findings on small groups on
the one hand; on the [p. 6] other, to extract relevant principles from the work coming from the
psychological laboratory.
2. To formulate problems and hypotheses relating to one another the indications of the two sets
of relevant findings, that is, from sociological and psychological research.
3. To test hypotheses thus derived with methods and techniques which are appropriate for the
particular problem -- experimental, observational, sociometric, questionnaire, or combinations
thereof, as the case may be.
Let us start with the term "small group" itself. The term "small group" is coming to mean all
things to all people. If the concept of small groups is considered at the outset, research on
small groups will gain a great deal in the way of selection of focal problems for investigation,
and hence effective concentration of efforts.
"Small group" may mean simply small numbers of individuals. If this is the criterion, any small
number of individuals in a togetherness situation would be considered a small group. But a
conception of small groups in terms of numbers alone ignores the properties of actual small
groups which have made their study such a going concern today.
One of the objectives of concentrating on small group research should be attainment of valid
generalizations which can be applied, at least in their essentials, to any group and to the
behavior of individual members. Accordingly, one of our first tasks was that of extracting some
minimum essential features of actual small groups from sociological work. In this task there is a
methodological advantage in concentrating on informally organized groups, rather than formally
organized groups in which the leader or head and other positions with their respective
responsibilities are appointed by a higher authority, such as a commanding officer or board. In
informally organized groups, group products and the particular individuals who occupy the
various positions are determined to a much greater extent by the actual interaction of
individuals. If care is taken at the beginning to refer to the general setting in which small groups
form and function, their products and structure can be traced through longitudinal observation
of the interaction process.
[p. 7] On the basis of an extensive survey of sociological findings, the following minimum
features in the rise and functioning of small groups were abstracted:
(1) There are one or more motives shared by individuals and conducive to their interacting with
one another.
(2) Differential effects on individual behavior are produced by the interaction process, that is,
each individual's experience and behavior is affected in varying ways and degrees by the
interaction process in the group (Note 2).
(3) If interaction continues, a group structure consisting of hierarchical status and role
relationships is stabilized, and is clearly delineated as an in-group from other group structures.
(4) A set of norms regulating relations and activities within the group and with non-members
and out-groups is standardized (Note 3).
Interaction is not made a separate item in these minimum features because interaction is the
sine qua non of any kind of social relationships, whether interpersonal or group. Since human
interaction takes place largely on a symbolic level, communication is here considered part and
parcel of the interaction process.
When group structure is analyzed in terms of hierarchical status positions, the topic of power
necessarily becomes an integral dimension of the hierarchy. Power relations are brought in as
an afterthought only if this essential feature of group hierarchy is not made part of the
conception of group. Of course, power does in many cases stem from outside of the group, and
in these cases the nature of established functional relations between groups in the larger
structure has to be included in the picture.
Our fourth feature relates to the standardization of a set of norms. The term "social norm" is a
sociological designation referring generically to all products of group interaction which regulate
members' behavior in terms of the expected or even the ideal behavior. Therefore, norm does
not denote average behavior (Note 4). The existence of norms, noted by sociologists, has been
experimentally tested by psychologists in terms of [p. 8] convergence of judgments of different
individuals (Sherif, 1936), and in terms of reactions to deviation (Schachter, 1952). A norm
denotes not only expected behavior but a range of acceptable behavior, the limits of which
define deviate acts. The extent of the range of acceptable behavior varies inversely with the
significance or consequence of the norm for the identity, integrity, and major goals of the group.
With these minimum essential features of small informally organized groups in mind, a group is
defined as a social unit which consists of a number of individuals who, at a given time, stand in
more or less definite interdependent status and role relationships with one another, and which
explicitly or implicitly possesses a set of norms or values regulating the behavior of
the individual members, at least in matters of consequence to the group.
Common group attitudes or sentiments are not included in this definition because social
attitudes are formed by individuals in relation to group norms as they become functioning parts
in the group structure. At the psychological level, then, the individual becomes a group member
to the extent that he internalizes the major norms of the group, carries on the responsibilities,
meets expectations for the position he occupies. As pointed out by various authors, his very
identity and self conception, his sense of security become closely tied to his status and role in
the group through the formation of attitudes relating to his membership and position. These
attitudes may be termed "ego-attitudes" which function as constituent parts of his ego system.
On the basis of findings at a sociological level, hypotheses concerning the formation of small in-
groups and relations between them were derived and tested in our 1949 camp experiment
(Sherif and Sherif, 1953). One of the major concerns of that study was the feasibility of
experimental production of in-groups among individuals with no previous role and status
relations through controlling the conditions of their interaction.
The hypotheses tested were:
(1) When individuals having no established relationships are brought together to interact in
group activities with common goals, they produce a group structure with hierarchical statuses
[p. 9] and roles within it.
(2) If two in-groups thus formed are brought into functional relationship under conditions of
competition and group frustration, attitudes and appropriate hostile actions in relation to the out-
group and its members will arise and will be standardized and shared in varying degrees by
group members.
As sociologists will readily recognize, testing of these hypotheses is not so much concerned
with the discovery of new facts as getting a clearer picture of the formative process under
experimentally controlled conditions. It aims rather at singling out the factors involved in the rise
of group structure, group code or norms, and in-group---out-group delineations which will make
possible their intensive study with appropriate laboratory methods on the psychological level.
To test these hypotheses, 24 boys of about 12 years of age from similar lower middle-class,
Protestant backgrounds were brought to an isolated camp site wholly available for the
experiment. The early phase (Stage 1) of the study consisted of a variety of activities permitting
contact between all the boys and observation of budding friendship groupings. After being
divided into two groups of 12 boys each, in order to split the budding friendship groupings and
at the same time constitute two similar units, the two groups lived, worked and played
separately (Stage 2). All activities introduced embodied a common goal (with appeal value to
all), the attainment of which necessitated cooperative participation within the group.
At the end of this stage, there developed unmistakable group structures, each with a leader and
hierarchical statuses within it, and also names and appropriate group norms, including
sanctions for deviate behavior. Friendship preferences were shifted and reversed away from
previously budding relationships toward in-group preferences. Thus our first hypothesis
concerning in-group formation was substantiated.
In the final phase (Stage 3) of the 1949 experiment, the two experimentally formed in-groups
were brought together in situations which were competitive and led to some mutual frustration,
as a consequence of the behavior of the groups in relation to each other. The result of
intergroup contact in these conditions was [p. 10] enhancement of in-group solidarity,
democratic interaction within groups, and in-group friendship, on the one hand. On the other
hand, out-group hostility, name calling and even fights between the groups developed,
indicating that in-group democracy need not lead to democratic relations with outsiders when
intergroup relations are fraught with conditions conducive to tension. The resistance which
developed to post-experimental efforts at breaking down the in-groups and encouraging friendly
interaction indicates the unmistakable effect of group products on individual members. Thus the
results substantiated the second hypothesis concerning determination of norms toward out-
groups by the nature of relations between groups and demonstrated some effects of intergroup
relations upon in-group functioning.
One of the main methodological considerations of this experiment was that subjects were kept
unaware of the fact that they were participating in an experiment on group relations. The view
that subjects cease to be mindful that their words and deeds are being recorded is not in
harmony with what we have learned about the structuring of experience. The presence of a
personage ever observing, ever recording our words and deeds in a situation in which our
status and role concerns are at stake cannot help coming in as an important factor in the total
frame of reference. Therefore, in our work, the aim is to establish definite trends as they
develop in natural, life-like situations and to introduce precision at choice points when this can
be done without sacrificing the life-like character which gives greatest hope for validity of these
trends.
The study just summarized illustrates the testing of hypotheses derived from sociological
findings in experimentally designed situations. The next point relates to psychological findings,
generalizations, and laboratory techniques relevant for the study of experience and behavior of
individual group members. Here our task is to achieve a more refined analysis on a
psychological level of individual behavior in the group setting through precise perceptual and
judgmental indices. If such data obtained through precise judgmental and perceptual indices
and other appropriate techniques are in line with findings concerning group relations on the
sociological level, then we shall be moving toward integration of psychological and sociological
approaches in the study of group relations.
[p. 11] Here only the bare essentials can be stated of the psychological principles from a major
trend in experimental psychology which are utilized in designing the experiments to be reported
(Note 5).
Judgments and perceptions are not merely intellectual and discrete psychological events. All
judgments and perceptions take place within their appropriate frame of reference. They are
jointly determined by functionally related internal and external factors operating at a given time.
These interrelated factors -- external and internal -- constitute the frame of reference of the
ensuing reaction. Observed behavior can be adequately understood and evaluated only when
studied within its appropriate frame of reference or system of relations. The external factors are
stimulus situations outside of the individual (objects, persons, groups, events, etc.). The internal
factors are motives, attitudes, emotions, general state of the organism, effects of past
experience, etc. The limit between the two is the skin of the individual -- the skin being on the
side of the organism.
It is possible, therefore, to set up situations in which the appraisal or evaluation of a social
situation will be reflected in the judgments and perceptions of the individual. In short, under
appropriate and relevant conditions, the way the individual sizes up a situation in terms of the
whole person he is at the time can be tapped through apparently simple perceptual and
judgmental reactions.
An additional principle should be clearly stated because of certain conceptions in psychology
which imply that perception is almost an altogether arbitrary, subjective affair. If external
stimulus situations are well structured in definite objects, forms, persons, and groupings,
perception will correspond closely to the stimulus structure on the whole. This is not to say that
functionally related internal factors do not play a part in the perception of structured situations.
The fact that some well-structured situations are singled out by the individual as "figure" rather
than others indicates that they do. Such facts are referred to under the concept of perceptual
selectivity.
If, on the other hand, the external field is vague, unstructured, in short, allows for alternatives --
to that extent the relative weight of internal factors (motives, attitudes) and social [p. 12] factors
(suggestion, etc.) will increase. It is for this reason that the exhortations of the demagogue are
relatively more effective in situations and circumstances of uncertainty. Since perceptions and
judgments are jointly determined by external and internal factors, it is possible to vary the
relative weights of these factors in differing combinations, giving rise to corresponding
judgmental and perceptual variations. This has been done in various experiments. In a study
carried out as part of our research program at the University of Oklahoma, James Thrasher co-
varied the stimulus situation in gradations of structure and the nature of interpersonal relations
of subjects (strangers and friends) to determine the reciprocal effects of these variations on
judgmental reactions. It was found that as the stimulus situation becomes more unstructured,
the correspondence between stimulus values and judgment values decreases and the
influence of social factors (established friendship ties in this case) increases (Thrasher, 1954).
Following the implications of the above, it is plausible to say that behavior revealing
discriminations, perceptions, evaluations of individuals participating in the interaction process
as group members will be determined ---
- not only by whatever motivational components and unique personality characteristics each
member brings with him,
- not only by the properties of external stimulus conditions (social or otherwise),
- but as influenced, modified, and even transformed by these and by the special properties of
the interaction process, in which a developing or established state of reciprocities plays no
small part. Interaction processes are not voids.
The starting point in our program of research was the experimental production of group norms
and their effects on perception and judgment (Sherif, 1936). This stems from our concern for
experimental verification of one essential feature of any group -- a set of norms (feature 4 of
small groups above). Groups are not transitory affairs. Regulation of behavior in them is not
determined by the immediate social atmosphere alone.
Especially suggestive in the formulation of the problem [p. 13] was F. Thrasher's observation on
small groups that behavior of individual members is regulated in a binding way (both through
inner attachment and, in cases of deviation, through correctives applied) by a code or set of
norms. Equally provocative in this formulation was Emile Durkheim's Elementary Forms of
Religion, in which a strong point was made of the rise of representations collectives in
interaction situations and their effect in regulating the experience and outlook of the individual.
After thus delineating the problem, the next step was to devise an experimental situation which
lacked objective anchorages or standards (i. e., was vague or unstructured) in order to
maximize the effects of the social interaction process. When individuals face such an
unstructured stimulus situation they show marked variations in reaction. However, such marked
individual variations will not be found if the stimulus is a definite, structured object like a circle
or a human hand. There will be agreement among individuals, on the whole, when they face a
circle or a normal hand even if they are five thousand miles apart and members of different
cultures. The fact of objective determination of perception and judgment and the ineffectiveness
of social influences (suggestion, etc.) in relation to structured stimuli was clearly noted in the
original report of this experiment in several contexts. In a later publication, in order to stress
cases of objective determination of psychological processes, a chapter was devoted to the
effects of technology and its decisive weight in determining social norms and practices, with
numerous illustrations from various parts of the world. Among them was our study conducted in
the early 1940's of five Turkish villages with varying degrees of exposure to modern technology,
specifically dealing with the compelling effects of such differential exposure on judgmental,
perceptual, and other psychological processes (Note 6).
The experimental situation chosen for the study of norm formation was the autokinetic situation
(the apparent movement of a point of light in a light-proof room lacking visible anchorages). The
dimension chosen was the extent of movement. As this study is reported in detail in various
places, I shall give only the bare essentials.
First it was established that the judgment of the extent of movement for given brief exposures
varies markedly from [p. 14] individual to individual. Then individuals were brought to the
situation to make their judgments together. If, during the course of their participation, their
judgments converge within a certain range and toward some modal point, we can say they are
converging to a common norm in their judgments of that particular situation. It is possible,
however, that this convergence may be due to immediate social pressure to adjust to the
judgments spoken aloud by the other participants in the situation. Therefore, going a step
further, if it is shown that this common range and modal point are maintained by the individual
in a subsequent session on a different day when he is alone, then we can say that the common
range and modal point have become his own.
The results substantiated these hunches. When individuals face the same unstable,
unstructured situation for the first time together with other participants, a range of judgment and
a norm within it are established which are peculiar to that group. After the group range and
norm are established, an individual participant facing the same situation alone makes his
judgments preponderantly in terms of the range and norm that he brings from the group
situation. But convergence of judgments is not as marked as this when individuals first go
through individual sessions and then participate in group sessions.
When the individual gives his judgments repeatedly in the alone situation, the judgments are
distributed within a range and around a modal point peculiar to the individual. This finding has
important theoretical implications. The underlying psychological principle, in individual and
group situations, is the same, namely that there is a tendency to reach a standard in either
case. Here we part company with Durkheim and other sociologists who maintained a dichotomy
between individual and social psychology, restricting the appearance of emergent properties to
group situations alone. In both cases, there are emergent properties. In the individual sessions
they arise within the more limited frame of reference consisting of the unstructured stimulus
situation and special psychological characteristics and states of the individual; whereas in
togetherness situations the norm is the product of all of these within the particular interaction
situation. The norm that emerges in group situations is not an average of individual norms. It is
an emergent product which cannot be simply extrapolated from individual situations; the
properties of the unique interaction process have to be brought into the [p. 15] picture.
Therefore, the fact remains that group norms are the products of interaction process. In the last
analysis, no interaction in groups, no standardized and shared norms.
In a subsequent unit, it was found that a characteristic mode of reaction in a given unstructured
situation can be produced through the introduction of a prescribed range and norm (Sherif,
1937). When one subject is instructed to distribute his judgments within a prescribed range and
around a modal point which vary for each naive subject, the preponderant number of judgments
by the naive subjects come to fall within the prescribed range and around the modal point
introduced for them, and this tendency continues in subsequent alone sessions. This tendency
is accentuated if the cooperating subject has prestige in the eyes of the naive subject. These
findings have been substantiated in a number of studies. For example, it has been shown that
the tendency to maintain the prescribed range persists after several weeks (Bovard, 1948). In a
recent experiment Rohrer, Baron, Hoffman, and Swander (1954) found that social norms
established in the autokinetic situation revealed a rather high degree of stability even after a
lapse of one year. This stability of an experimentally produced norm acquires particular
significance in view of the facts in the study that (a) the subjects had first formed individual
norms on the basis of actual movement prior to the establishment of divergent norms in a social
situation and (b) the norms stabilized in the social situations were revealed after the lapse of
one year in alone situations, i.e., without further social influence.
The actual presence of another person who makes judgments within a range prescribed by the
experimenter is not essential. Norman Walter (1952) demonstrated that a prescribed norm can
be produced through introduction of norms attributed to institutions with high prestige. A
prescribed distribution of judgments given by tape recording is similarly effective (Blake and
Brehm, 1954). A prescribed range can be established, without social influence, through prior
experience in a more structured situation with light actually moving distances prescribed by the
experimenter (Hoffman et al., 1953).
The advantages of a technique such as the autokinetic device for studying norm formation and
other aspects of group relations are: (1) Compared with gross behavioral observations, [p. 16] it
yields short-cut precise judgmental indices along definite dimensions reflecting an individual's
own appraisal or sizing-up of the situation. (2) The judgmental or perceptual reaction is an
indirect measure, that is, it is obtained in relation to performance and situations which do not
appear to the subject as directly related to his group relations, his positive or negative attitudes.
The feasibility of using judgmental variations in this study constituted the basis of its use in
subsequent studies dealing with various aspects of group relations.
At this point, longitudinal research will bring more concreteness to the process of norm
formation. As Piaget (1932) demonstrated in his studies of rules in children's groups, the
formation of new rules or norms cannot take place until the child can perceive reciprocities
among individuals. Until then he abides by rules because people important in his eyes or in
authority say that he shall. But when the child is able to participate in activities grasping the
reciprocities involved and required of the situation, then new rules arise in the course of
interaction, and these rules become his autonomous rules to which he complies with inner
acceptance. Although in contrast to some still prevalent psychological theories (e. g., Freud),
these longitudinal findings are in line with observations on norm formation and internalization in
adolescent cliques and other informally organized groups. These are among the considerations
which led us to an intensive study of ego-involvements, and to experimental units tapping ego-
involvements in interpersonal relations and among members occupying differing positions in the
status hierarchy of a group.
These experimental units represent extensions of the approach summarized to the assessment
of positive or negative interpersonal relations, status relations prevailing among the members of
in-groups, positive or negative attitudes toward given out-groups and their members.
The first units along these lines dealt with interpersonal relations. It was postulated that since
estimates of future performance are one special case of judgmental activity in which
motivational factors are operative, the nature of relations between individuals (positive or
negative) will be a factor in determining variations in the direction of these estimates. This
inference was borne out first in a study showing that estimates of [p. 17] future performance are
significantly affected by strong positive personal ties between subjects (Note 7). In a later unit,
the assessment of personal relations through judgments of future performance was carried to
include negative interpersonal relations as well as positive (Harvey and Sherif, 1951). In line
with the hypothesis, it was found that individuals tended to overestimate the performance of
subjects with whom they had close positive ties and correspondingly to underestimate the
future performance of those with whom they had an antagonistic relationship.
The study of status relations in small groups followed (Harvey, 1953). This study is related to
feature 3 of the essential properties of groups discussed earlier in this chapter, namely, the rise
and effects of a status structure. Observations by the sociologist, William F. Whyte, gave us
valuable leads in formulating the specific problem of this study. During one period, a Street
Corner clique that Whyte observed was engaged seriously in bowling. Performance in bowling
became a sign of distinction in the group. At the initial stage, some low status members proved
themselves on a par with high status members, including the leader. This ran counter to
expectations built up in the group hierarchy. Hence, in time, level of performance was stabilized
for each member in line with his relative status in the group. In the experiment, Harvey first
ascertained the status positions of individual members in adolescent cliques. This was done
through status ratings by adults in close contact with the subjects, through sociometric ratings
from clique members, and through observations of some of the cliques by the experimenter
during their natural interaction. Cliques chosen for the final experiment were those in which
there was high correspondence between the status ratings obtained.
The overall finding was that the higher the status of a member, the greater his tendency and
that of other group members to overestimate his future performance. The lower the status of a
group member, the less is the tendency of other group members and of himself to overestimate
his performance, even to the point that it is underestimated. If these results are valid, it should
prove possible to predict leaders and followers in informal groups through judgmental variations
exhibited in the way of over- and under-estimations of performance.
In the summer of 1953 our first attempt was made at a [p. 18] large-scale experiment starting
with the experimental formation of in-groups themselves and embodying as an integral part of
the design the assessment of psychological effects of various group products (Note 8). This
assessment involved laboratory-type tasks to be used in conjunction with observational and
sociometric data. The overall plan of this experiment was essentially like that of the 1949 study
which was summarized earlier. However, it required carrying through a stage of in-group
formation, to a stage of experimentally produced intergroup tension, and finally to integration of
in-groups. The scope of this experiment embodying laboratory-type procedures at crucial points
in each stage proved to be too great for a single attempt. During the period of intergroup
relations, the study was terminated as an experiment owing to various difficulties and
unfavorable conditions, including errors of judgment in the direction of the experiment.
The work completed covered the first two stages and will be summarized here very briefly. The
plan and general hypotheses for these stages are similar, on the whole, to those of the 1949
study summarized earlier.
Prior to the experiment, subjects were interviewed and given selected tests administered by a
clinical psychologist. The results of these assessments are to be related to ratings made by the
experimental staff along several behavioral dimensions during the experiment proper when in-
group interaction had continued for some time.
At the end of the stage of group formation, two in-groups had formed as a consequence of the
experimental conditions, although the rate of group formation and the degree of structure in the
two groups were somewhat different.
Our hypothesis concerning experimental formation of in-groups substantiated in the 1949 study
was supported. As a by-product of in-group delineation we again found shifts and reversals of
friendship choices away from the spontaneous choices made prior to the division of groups and
toward other members of the in-group.
At the end of this phase of in-group formation, just before the first scheduled event in a
tournament between the two groups, [p. 19] psychological assessment of group members
within each status structure was made through judgments obtained in a laboratory-type
situations. In line with methodological concerns mentioned earlier in the chapter, the
experimental situation was introduced to each group by a member of the staff with the proposal
that they might like to get a little practice for the softball game scheduled later that day. When
this proposal was accepted, the experimenter took each group separately and at different times
to a large recreation hall where he suggested turning the practice into a game, in which
everyone took turns and made estimates of each others' performance. This was accepted as a
good idea. Thus each boy took a turn at throwing a ball at a target 25 times and judgments of
his performance were made by all members after each trial.
It should be noted that in previous studies, judgments of future performance were used as an
index. The important methodological departure here was using as the unit of measurement the
difference between actual performance and judgment of that performance after it was
executed. In order to do so, the stimulus situation had to be made as unstructured as possible
so that the developing status relations would be the weighty factor in determining the direction
of judgmental variations.
In line with our hypothesis in this experimental unit, the results indicate that variations in
judgment of performance on the task were significantly related to status ranks in both groups
(Sherif, White and Harvey, 1955). The performance of members of high status was
overestimated by other group members; the performance of members of low status tended to
be underestimated. The extent of over- or under- estimation was positively related to the status
rankings. Variations in judgment of performance on this task were not significantly correlated
with skill, or actual scores, of members. This should not be interpreted to mean that skill can be
discarded as a factor, or that it would not be highly related to judgmental variation in a more
structured task. Of the two groups, skill seemed to be of relatively greater importance in the
group which achieved less stability and solidarity. This is one of several indications that the
relationship between judgmental variation and status rankings is closer in the group of greater
solidarity and greater stability of structure. This finding of a relationship between degree of
stability of the [p. 20] structure, on the one hand, and psychological response of members as
revealed in their judgments, on the other, points to the necessity of systematic concern with the
degree of group structure and solidarity as a variable in small group studies. In particular it
should be brought systematically into the study of leadership and problems of conformity
(Sherif, 1954).
We hope to gain greater understanding of the relationship between stability of group structure
and psychological reactions as revealed by judgmental indices through a new study designed
for this purpose. In this attempt the task will be held constant and the degree of established
status relationships among subjects will be varied. At one extreme, subjects will be complete
strangers; at the other extreme, subjects will be members of highly structured groups. The
hypothesis to be tested is that judgments will be more a function of actual performance in the
task in the case of strangers, and progressively more a function of existing status relations and
less of skill with the increasing degrees of stability of group structure.
Following the experimental assessment of psychological effects of group structure in existing
and in experimentally formed in-groups, the next step in our program of research was to extend
the use of judgmental variation techniques to the level of intergroup relations among already
existing groups. Such an experimental unit has recently been completed by O. J. Harvey
(1954). Harvey investigated relations between existing informally organized groups and their
effects on in-group functioning and on evaluations of the in-group and out-group. Organized
cliques were chosen on the same basis as those in the study of status relations in existing
informally organized groups already summarized. In the first experimental session, in-group
members judged each others' performance on a task. In the second session, two cliques with
either positive or negative relationships with each other were brought to the situation together.
Here a similar procedure was followed, with in-group members judging performance both of
other in-group members and performance of members of the functionally related out-group. In
addition, subjects rated in-group and out-group members on 10 adjectival descriptions
presented on a graphic scale. These ratings were included to yield data relevant to our
hypothesis concerning the nature of group stereotypes in the 1949 study and those of [p. 21]
Avigdor's study (1952) on the rise of stereotypes among members of cooperating and rival
groups.
Results obtained in this experiment bear out the hypotheses. Greater solidarity was evidenced
in the in-group when negatively related out-groups were present, as revealed by an increasing
relationship between judgmental variation and status ranks and by greater overestimation of
performance by in-group members. In-group performance was judged significantly above that
of out-group members when the groups were antagonistic, which was not the case when the
groups present were positively related to each other. Finally, results clearly show a much
higher frequency of favorable attributes for in-group members (e. g., "extremely considerate, "
"extremely cooperative") and a much higher frequency of unfavorable attributes given members
of an antagonistic out-group (e. g., "extremely inconsiderate", "extremely uncooperative"). The
difference between qualities attributed to in-group members and members of friendly out-
groups is much smaller and not so clear-cut, as would be expected.
Thus, having demonstrated the feasibility of experimental study of norm formation, of status
relations within groups, and of positive and negative attitudes between groups through
laboratory-type techniques, on the one hand, and, on the other, experimental production of in-
groups themselves in two previous studies, our next step is to carry through the large-scale
experiment along the lines of our 1953 attempt which will pull together all of these various
aspects into one design. Judgmental indices reflecting developing in-group and intergroup
relations are to be obtained through laboratory-type techniques at choice points in a way that
does not clutter the flow of interaction process. These judgmental indices can be checked
against data obtained through more familiar observational, rating, and sociometric methods. If
indications of the findings through judgmental processes are in line with the trends obtained by
gross observational and other methods, then we can say the generalizations reached are valid.
If this can be established, the laboratory-type experiment can be offered as a more precise and
refined method of assessing the effects of interaction processes in group relations.
This approach, which considers the behavior of individuals as an outcome of interaction
processes into which factors [p. 22] enter both from the individual himself with his unique
characteristics and capacities and from properties of the situation, affords a naturalistic
behavioral setting against which the claims of various personality tests can be evaluated.
The successive phases of this comprehensive experimental plan are:
1. Experimental production of in-groups themselves with a hierarchical structure and set of
norms (intra-group relations). In line with our 1949 and 1953 studies, this is done, not through
discussion methods, but through the introduction of goals which arise in the situations, which
have common appeal value, and which necessitate facing a common problem, leading to
discussion, planning and execution in a mutually cooperative way.
2. Bringing into functional relations the two experimentally formed groups in situations in which
the groups find themselves in competition for given goals and in conditions which imply some
frustration in relation to one another (intergroup tension).
3. Introduction of goals which cannot be easily ignored by members of the two antagonistic
groups, but the attainment of which is beyond the resources and efforts of one group alone. In
short, superordinate goals are introduced with the aim of studying the reduction of intergroup
tension to derive realistic leads for the integration of hostile groups.

Oklahoma. The remaining chapters of this book give an account of its planning, execution, and
findings.

[p. 27] CHAPTER 2
Approach, Hypotheses and General Design of the Study [1]
The focal concern of this study is intergroup relations. As an experiment in social psychology, it
undertakes to trace over a time period the formation and functioning of negative and positive
attitudes of members of one group toward another group and its members as a consequence of
experimentally introduced situations. Therefore, the main hypotheses relate to attitudinal and
behavioral trends predicted as a result of controlled alterations of the conditions in which
experimentally formed in-groups interact.
The general trend of findings from the sociology of small in-groups and their intergroup
relations and relevant findings from the work of experimental psychologists led us to the
experimental study of the problem of intergroup relations in successive stages. In the present
undertaking (Summer, 1954) it will be carried out in 3 successive stages. The main features of
these 3 successive stages are the following:
Stage 1: Experimental production of in-groups with a hierarchical structure and set of norms
(intra-group relations). In line with our 1949 and 1953 studies, this will be done, not through
discussion methods or through lecture or exhortation by resource persons or experts, but
through the introduction of goals which arise as integral parts in the situations, which have
common appeal value, and which necessitate facing a common problem, discussion, planning
and execution in a mutually cooperative way.
Stage 2: Bringing the two experimentally formed groups into functional relations in situations in
which the groups find themselves in competition for given goals and in conditions which imply
[p. 28] some frustration in relation to one another (intergroup tension).
Stage 3: Introduction of goals which cannot be easily ignored by members of the two
antagonistic groups, but the attainment of which is beyond the resources and efforts of one
group alone. Such goals will be referred to as superordinate goals throughout this report.
Superordinate goals are to be introduced with the aim of studying the reduction of intergroup
tension in order to derive realistic leads for the integration of hostile groups. Considerations
which led to the selection of this approach rather than other possible alternatives (such as a
common enemy, leadership technique or discussion techniques) are stated briefly in the
discussion of Stage 3 in the last part of this chapter.
It should be emphasized at the outset that individuals brought into an experimental situation to
function as small groups are already members of actual groups in their social settings and thus
have internalized values or norms (i. e., attitudes) which are necessarily brought to the
situation. With this consideration in mind and in order to give greater weight to experimentally
introduced factors in the situation, a special effort will be made in this study not to appeal to
internalized values or to prestige symbols coming from the larger setting in the formation and
change of positive or negative attitudes in relation to respective in-groups and out-groups.
Background of the Above Summary
The rationale that underlies the above formulation of our approach to the study of intergroup
relations stems from relevant findings in both sociology and psychology. They are stated more
fully elsewhere (Note 1). Here only a summary statement of these lines of development will be
given.
Empirical observations by social scientists and inferences made by psychologists without direct
experimental verification present a rather confusing picture at the present time. Therefore it is
necessary to state precisely the sense in which the concept "group" and the issue of relations
between them (intergroup relations) are used here:
A group may be defined as a social unit (1) which consists of a number of individuals who, at a
given time, stand in more or [p. 29] less definite interdependent status and role relationships to
one another and (2) which explicitly or implicitly possesses a set of values or norms of its own
regulating the behavior of individual members, at least in matters of consequence to the group.
In order that this definition not be unwieldy, common attitudes, common aspirations and goals
are omitted. Such shared attitudes, aspirations, and goals are related to and, in fact, are implicit
in the concept of common values or norms of a group. From the point of view of the members
within the group, these social units may be referred to as in-groups. Again from the point of
view of a member within the group, those social units of which he is not a part psychologically
or to which he does not relate himself may be referred to as out-groups. It follows that the term
intergroup relations refers to the relations between two or more in-groups and their respective
members. Whenever individuals belonging to one in-group interact, collectively or individually,
with another group or its members in terms of their group identification, we have an instance of
intergroup relations.
From a survey of empirical literature it can be stated that intergroup attitudes and behavior
regulated by them are produced in the form of social distances and standardized stereotypes
as a consequence of functional relations between in-groups. Once these intergroup attitudes
and stereotypes are standardized they take their place in the cultural repertory of the group and
in many cases, through the vehicle of language, outlast the very functional relations which were
responsible for their rise.
These functional relations between groups and their consequences, rather than the study of the
deviate individual, constitute the central problem of intergroup relations. Of course, this does
not imply a denial of various unique influences in the life history of the individual member (such
as personal frustrations, special hardships in the family or other situations). Such personal
influences in the life history may have a great deal to do with the individual becoming a non-
conformist or deviate in terms of the prevailing scales of attitudes of his group. But such unique
or personal influences do not determine the scale themselves. Rather they come in an
important way to determine the particular place the individual will occupy within these scales or,
in the case of non-conformists or deviates, the acceptance of a position outside of the scale.
[p. 30] Considerations determining the approach, plan, and hypotheses: At present there are
various and conflicting psychological approaches to the study of intergroup relations. It seems
that no amount of argument on an abstract level will prove the advantage of one approach over
another. Certain of the empirical considerations which led to the approach to be used in this
study will be mentioned briefly in the pages that follow.
The consequential intergroup behavior of individuals (largely revealing friction and tension at
the present time) is in terms of their membership in their respective groups. Intergroup behavior
of an individual which deviates considerably from the prevailing trends is not a typical case. If
the individual's intergroup behavior is too much out of line with the prevailing trend of his
respective groups, it is brushed aside or dealt with as deviate by other members.
One approach to intergroup relations is through the study of leadership. Even though
leadership undeniably contributes great weight in the shaping of intergroup relations,
concentration of research on leadership alone leaves out functional ties to which leadership
itself is organically related. Such an approach is in contradiction to the main trend in leadership
studies today. These studies are increasingly pointing to the necessity of considering
leadership in terms of the whole state of reciprocities within the group.
Another approach in intergroup problems concentrates efforts on in-group relations. Empirical
data seem to indicate that the nature of intergroup relations need not be in line with the
prevailing character of in-group relations. This approach, which concentrates on improving in-
group relations in order to improve intergroup relations, ignores the demonstrated
consequences attributable only to the particular character of the interaction process between
groups. Solidarity within the group need not be transferred to solidarity between groups, and in
fact may contribute to sharpened delineations between groups with all the attendant by-
products.
In short, the conception of the present study differs markedly from existing theories which posit
one factor or a few factors as sole or primary determinants of the course of intergroup relations.
(1) Inherent superiority or inferiority of human groups, [p.31] (2) national character ("war-like
people, " "peaceful people"), (3) deep-seated innate instincts of aggression or destruction, (4)
frustrations suffered individually, (5) direct economic gain, (6) the character of leadership - - -
are variously advanced as sole or primary determinants of intergroup relations. Each of these
theories still has its strong supporters.
The present approach does not deny that some such factors may, singly or in combination, be
operative as factors in determining the course of intergroup relations (excepting specifically the
first and third listed above). "National character," frustrations suffered in common and
experienced as a common issue, certain economic gains which become shared goals, or the
particular character of the group's leadership may variously become the more weighty
determinant of intergroup relations under a given set of circumstances (Note 2).
But conflicting evidence leads us to assert that the weighty factor determining intergroup
relations will not be the same for all circumstances. For example, in settled times when in-
groups are in a state of greater stability, national character as formed at the time and the
existing scale of social distance (or prejudice) will regulate, on the whole, the particular pattern
of intergroup relations. But in times of greater flux or crises (due to the impact of technological,
cultural, socioeconomic and even military events) some other factor or factors take the
upperhand.
One primary point of departure in our approach then, is the principle that various factors are
functionally interrelated. In this respect the present approach is opposed to theories which
make this or that factor sovereign in its own right; it attempts rather to ascertain the relative
weights of all the possible factors that may be operative at the time.
The functional relatedness of various factors leads us to the cardinal psychological principle of
our whole plan of study:
In the study of (intra- and inter-) group relations the relative contribution of given external
stimulus factors and internal factors pertaining to participating individuals (hunger, sex, status
desire, complexes, etc.) have to be analyzed within the framework of the ongoing interaction
process among the members in question.
[p. 32] The relative contribution of an external stimulus factor, or an attitude, a drive, or other
internal factors, cannot be simply extrapolated from individual situations to interaction
situations. Interaction processes are not voids. Whatever drives, motives, or attitudes the
individual brings into the situation operate as deflected, modified, and, at times, transformed in
the interaction process among the several individuals (who stand or come to stand in time in
definite role relations toward one another).
The application of this cardinal principle to the study of group relations is derived from more
basic findings in the field of judgment and perception. The judgment of a given weight is not
determined solely by its absolute value, but also, within limits, by its relative position in the
scale of which it is a part and by the presence or absence of other functionally related
anchoring stimuli with values within and without the scale. Likewise placement of attitudinal
items on a scale with categories specified by the experimenter or with categories chosen by the
subject is determined not only by whatever intrinsic value these items may have when
considered singly, but also by their relation to one another and their relation to the stand that
the individual has taken on the issue.
Following the implications of this general psychological principle, it may be plausible to state
that behavior revealing discriminations, perceptions, evaluations of individuals participating in
the interaction process as group members will be determined not only by whatever motivational
components and personality characteristics each member brings with him, not only by the
properties of stimulus conditions specified in an unrelated way, but as influenced, modified, and
even transformed interdependently by these and the special properties of the interaction
process, in which a developing or established state of reciprocities (roles, statuses) plays no
small part. The developing state of reciprocities between individual members can be measured
in various differentiated dimensions (e. g., status, popularity, initiative, etc.).
In short, one cannot directly extrapolate from the knowledge of stimulus conditions alone, or
motivational components of participating individuals alone, but one has to study behavior in the
framework of the actual interaction process with its [p. 33] developing reciprocities.
Carrying this line of conceptualization to the area of inter-group relations, one should start with
the recognition that the area of interaction between groups cannot be directly extrapolated from
the nature of relations within groups or prevailing practices within them, even though a careful
analysis of intra-group relations is an essential prerequisite in any approach to intergroup
relations. Numerous instances of intergroup relations in which the pattern (positive or negative)
is different from the pattern prevailing within the respective in-groups might be mentioned.
The interaction process between groups and its consequences have to be studied in their own
right in addition to studying relations prevailing within the in-groups in question.
The conceptual orientation outlined above determined:
1. the formulation of specific hypotheses,
2. the design of the experiment through 3 successive stages,
3. the choice of criteria in selection of subjects and the choice of setting that will not permit the
direct intrusion of influences other than those experimentally introduced,
4. the special considerations related to observational and experimental techniques to be used
in the collection of data, and the specific roles staff members will occupy.
Methodological Considerations
The problem of intergroup relations has not been made the domain of experimentation.
Literally, there are only a few studies specifically designed to experiment on intergroup
relations. Therefore, the present study undertakes to define main functional relations involved
in the problem and to point to some unmistakable trends on the basis of data obtained.
In experimental study of intergroup relations it is necessary that various conditions between
groups be experimentally [p. 34] introduced and manipulated, the nature of these conditions
being defined, and the consequences of their variation predicted.
Recent research in both psychology and sociology and indications of attempts by practitioners
in this area are making it increasingly evident that theoretical and practical problems of group
relations, including attitudes and change of attitudes regulating behavior of individuals within
their respective groups (in-groups) and with out-groups, have to be studied in terms of the
interaction processes within and between appropriate group settings.
The usual practice in attitude studies has been to study the effects of already existing attitudes,
or to measure attitudes that are already formed. When carried out apart from particular group
settings, the study of motives (drives), frustrations, past experience, etc., (which are certainly
operative in the formation, functioning, and change of social attitudes pertaining to group
relations) has given us items of information whose validity has not been proven in actual issues
of group relations. The attempt in this study is to trace the formation, functioning, and change of
attitudes towards one's own group, toward its various members, and towards out-groups and
their members within the setting of group interaction processes, and as consequences thereof.
In-groups themselves and the attitudes of members towards one another and toward the in-
group as a whole are to be experimentally produced. In other words, group attitudes (both intra-
and intergroup) will start from scratch and will be produced as a consequence of interaction
processes in intra- and intergroup relations through the introduction of specified experimental
conditions. The methodological gain from the experimental production of attitudes whose
effects or change are to be studied or measured needs no elaboration.
Considerations such as those briefly mentioned above determine the approach taken, the
specific hypotheses formulated, and the design of the experiment in 3 successive stages in the
present 1954 study. Likewise they determine the choice of particular methods and cautions to
be pursued in the collection of data.
[p. 35] To approximate as much as possible the natural process of spontaneous group
formation, of in-group and out-group delineation with its consequences so abundantly reported
in the literature on small groups, subjects will be kept unaware of the fact that this is an
experiment on intergroup relations. (See Subject Selection in the next chapter for information
given to teachers and parents concerning the experiment.)
Data concerning in-group formation (Stage 1) and inter-group functioning (in Stages 2 and 3)
will be obtained through participant observers who are perceived as part and parcel of the
situation by the subjects. All of the staff members directly in contact with the subjects will
participate in the role of usual camp personnel, or some role not out-of-ordinary in a camp
situation. Moreover, the participant observers should not be detected by the subjects while
recording observations contrary to the natural functions of their announced roles. The argument
that subjects cease to be mindful that their words and other behavior are being observed and
recorded is not in harmony with what we have learned concerning the structuring of perception.
The presence of a personage ever observing, ever recording our words and deeds in a
situation in which our status and role concerns are at stake, cannot help coming in as an
important anchorage in the framework of the interaction process in question. Candid recordings
of conversation and moving pictures taken at choice points without the awareness of the
subjects will be valuable in addition to other observational data.
All the goals in the in-group stage and in the negative and positive intergroup stages will be
introduced through conditions inherent in immediate situations (such as eating, overnight
camping or some activity expressly desired by the subjects), and not in the form of abstract
incentives distantly related to the immediate goals of ongoing activities and situations. For
example, attainment of food will be introduced, not as a hypothetical problem or discussion
situation, but through arranging conditions at a time when group members are getting hungry in
a place where no other food is available so that members have to cooperate with one another
to prepare available ingredients with facilities in the situation. (After subjects take the initiative
along some plan, all necessary help and skill can be extended to carry out their plan more
effectively.)
[p. 36] The technique of problem solving, that is, attainment of goals introduced in the manner
described above, will not be through methods introduced by the experimenter, such as
discussion method or lecture method. One of the guiding principles in the present study is that
an actual problem situation faced by group members, as a common goal to be attained or a
common deprivation to be taken care of, will necessarily lead to various suggestions, counter-
suggestions, proposals and their weighing - - - in short, to discussion by group members.
When the group is faced with a situation involving common goals or deprivations, group activity
will arise. This group activity may be in the form of suggestions from various members, leading
to discussion, decisions, planning and execution. When group activity in relation to common
goals is initiated, effective ways of dealing with the situation may involve group discussion, or
analysis of the situation by a member who is conceded to know more about the topic than
others, or (especially if the group is well-structured or the situation and available means
sufficiently compelling) more direct action by higher status members or by the whole group may
be taken. Those familiar with sociological findings on informally organized small groups, know
well that such groups, facing plans to be executed or problems to be solved, do discuss, do
plan, and do execute plans. In this interaction process involving an actual problem or goal
situation perceived as common to the group, discussion of alternatives has its place, at times
exhortations (lectures) and skills of particular members in verbal and non-verbal ways have
their places. The various activities involved in the interaction process, viz., discussion,
exhortation, planning, and execution, may be carried out in sequence, or in rapid succession, or
the common decision may be implicit in the action itself, if the goal and means stand out
clearly. The sequence followed and methods used will be determined in part by the nature of
the problem, in part by the particular character of group structure (in which leadership, as part
and parcel of the hierarchical structure of the group, plays no small part), in part by the
particular set of values or norms prevailing in the group, and also by the character and norms
of the general sociocultural setting of which the group in question is a part.
Emphasis on studying the interaction process in a natural setting, while approximating
experimental control and techniques, does not eliminate the possibility of checking the validity
of observed [p. 37] trends by precise laboratory techniques at "choice" points. If there is any
validity in the recent generalizations concerning perceptual and judgmental variations
("distortions") as a function of attitude or motive, relevant perceptual or judgmental tasks of the
type used in the laboratory can very well be introduced at a few choice points. The stimulus
materials used in these experimental units are of an indirect and unstructured type not involving
direct questions about developing group attitudes. The procedures are perceived by the S' s as
part of the camp activities, and not as experiments which clutter the flow of their interaction
process.
In fact, on the methodological side, the plan of the study aims at two additional objectives:
The first involves the introduction of laboratory-type experimental procedures as supplements
for obtaining data concerning the effects of group interaction with the aim of establishing short-
cut methods for tapping behavioral trends to supplant laborious, gross behavior observations
(see experimental units at the end of Stages 1, 2, 3 later in this chapter).
The second is to secure personal data (e. g., intelligence, personal characteristics) through
available testing procedures which can be related to various dimensions of behavior manifested
in the interaction process in various stages. This aspect is not to be carried out in the present
1954 study owing to lack of facilities. As this line of research develops it can be brought to the
foreground as one of the important problems.
Subjects
Subjects will be 24 twelve-year-old boys from established Protestant families of middle-class
socioeconomic standing, who are normal (no "problem" cases), who have not experienced any
unusual degrees of frustration in their homes or other situations, who are not school or social
failures (no isolates), and who have a similar educational level. (See section on subject
selection, Chapter 3.)
[p. 38] A nominal fee of $25 or less will be charged. This nominal fee will give us the privilege of
asking parents not to visit their boys during the experiment. Staff members will have no visitors.
Three Successive Stages and the Hypotheses
The hypotheses will be listed under their appropriate stages, since the account of these stages
specifies in outline the conditions under which the particular hypothesis holds true.
Our general hypothesis in regard to intergroup relations (which is the main concern of the
present study) is that intergroup attitudes and behavior are determined primarily by the nature
of functional relations between groups in question (and not primarily by the pattern of relations
and attitudes prevailing within groups themselves, nor primarily by the deviate or neurotic
behavior of particular individual members who have suffered more than the usual degree of
frustration in their personal life histories).
Both the 1949 and 1953 experiments started with a stage of spontaneous friendship choices
(Note 3). This stage, to which the first days of the experiments were devoted, was introduced to
rule out the possibility of attributing the experimental in-group formation to personal affinities
that subjects develop for one another. This alternative explanation was ruled out on the basis of
reversals of friendship choices away from interpersonal preferences and in the direction of the
experimentally produced in-groups in our 1949 and 1953 experiments. The stage of
interpersonal friendship choices, therefore, is eliminated from this 1954 undertaking, and the
study is designed in 3 stages instead of the more complex 4 stage design of the 1953 attempt.
In the two previous studies, the assignment of the subjects to two experimental groups was
done towards the end of the first stage, that of spontaneous friendship choices. The basis for
this division was not only the splitting of spontaneous friendship choices but also matching the
groups as much as possible in terms of observed skills, athletic ability, etc., as well as in terms
of data collected during the period of subject selection. Since dropping the period of
spontaneous friendship choices [p. 39] eliminates the possibility of actual observation at the
camp prior to assignment of subjects to two groups, we have to rely exclusively on the data
from the observations at schools, teacher evaluations, school ratings, and data from interviews
in actual home situations during the subject selection period. Utmost care will be exhibited by
staff members to obtain two groups matched in as many dimensions as possible relevant to the
activities that will be introduced, especially those to be utilized in the intergroup stages.
Stage 1: (5-6 days) Experimental in-group formation
The chief aim of Stage 1 is the production of in-groups through manipulation of conditions in
which interaction takes place. This step is necessary in order that intergroup relations may be
studied between in-groups, whose formation and functioning can be specified.
With the aim of specifying the formation and structure of the experimental in-groups, the two
groups will be kept apart and their activities separated as much as possible, especially during
the first days of this stage. Otherwise any functional contacts between the two groups would
certainly have some consequence both for in-group formation and for the later stages of
intergroup relations.
Conditions conducive to bringing about in-group formation (with hierarchical statuses and roles
which will be clear-cut at the upper and bottom ends of the hierarchy) will consist of a series of
common and interdependent activities prompted by goals integral to the actual situations in
which the subjects find themselves (e. g., getting a meal when they are hungry or water when
thirsty). The attainment of the goal will necessarily require cooperation and reciprocal relations.
As a result, the initial discussion and the activities that follow will be real to the subjects, unlike
discussion topics introduced or hinted by experimenters (or leaders) which are not immediately
inherent in the situation. (Topics used in many discussion group studies are often conducive to
individual 'shining' in verbal skills or debating.)
The effects of the series of activities conducive to group formation will be studied in terms of:
[p. 40] (a) behavioral observations - - - verbal and non-verbal,
(b) ratings of emerging relationships by the participant observers (looking from outside),
(c) sociometric ratings in several relevant dimensions (looking from inside),
(d) experimental indices in terms of judgmental and perceptual variations reflecting the
reciprocal role and status attitudes that emerge among group members toward each other.
Before these indices are obtained, we can make predictions of the direction and degree of such
variations.
As emphasized in the introductory theoretical and methodological considerations, the focal
point is to maintain the natural flow of the interaction process within groups and, later, between
groups under conditions which appear life-like to the subjects. Any observational procedure, or
laboratory-type experiment or repetition of sociometric tapping which clutters the flow of
interaction is antithetical to the main conception of this study. Therefore, only one judgmental
experiment will be used during the stage of in-group formation. It is perfectly feasible to design
an experiment primarily to study in-group formation and related problems and to devote the
entire time to it. In that case, of course, it would be possible to introduce various experiments
studying the progressive development of in-group structure and its effects on in-group
members.
Hypothesis 1 (Stage 1)
A definite group structure consisting of differentiated status positions and reciprocal
roles will be produced when a number of individuals (without previously established
interpersonal relations) interact with one another under conditions (a) which
situationally embody goals that have common appeal value to the individuals, and
(b) which require interdependent activities for their attainment.
The hypothesis above is formulated on the basis of empirical findings by sociologists like F.
Thrasher, Clifford Shaw, and William Whyte. These and other authors stated generalizations [p.
41] in line with it. Our findings in this respect will serve as experimental verification. This
hypothesis was supported by the results of both our 1949 and 1953 experiments cited
previously.
The hypothesis will be considered to be verified if the individuals can be placed on a pyramidal
hierarchy (the leader being at the apex) on the basis of (a) observational data, (b) status ratings
of subjects in the respective groups by participant observers, and (c) sociometric indices.
(a, b) Observational data: The ratings of emerging status relations will be a part of the daily
observational reports of the participant observers. Thus, the ratings will serve as a day-to-day
index of the trend from mere togetherness situations (in which unstable, transitory differential
effects are manifested) to various degrees of stabilization of established reciprocities which
constitute the group structure at a given time. When three consecutive ratings (especially of
positions at the top and bottom of the status hierarchy) by participant observers of their
respective groups show a high degree of correspondence, we can say a definite in-group
structure has formed. At this point the similar ratings independently made by junior counselors
and other staff members who have had sufficient contact with the groups may be used as
further checks. At that time, sociometric ratings and the judgmental experiment with the target
board will be introduced (see c and d below).
Observational data consisting of the frequencies of suggestions for activities made by various
members and the proportion of acceptance and observance of these suggestions will be
obtained. The latter measure might be termed the initiative ratio.
Other observational data along various dimensions will be desirable. Observers will make their
ratings of group structure along these dimensions.
Frequency of suggestions (for engaging in this or that activity, etc.) addressed to various group
members is one such dimension. It is a plausible hunch that the number of suggestions for
group activities which are received by various members will be proportional to the status each
achieves in the group. When members are placed according to the frequencies of suggestions
addressed to them, we may be getting a placement of members [p. 42] pyramidal in shape very
much like the one mentioned above. It is plausible to state this tendency in the form of an
auxiliary hypothesis:
Hypothesis 1 a (Stage 1)
If a definite group structure develops, it will be reflected in a consistent pattern in
directions of communication. The specific pattern in direction of communication will
be as follows: The higher the status of a group member the greater the frequency of
suggestions (for group activities) addressed to him.
It seems feasible to represent the pattern in directions of communication visually in the form of
a chart. We should think that through the course of a study such as this, variations in such
charts would be obtained. The chart of directions of communication at a given time will
correspond closely to the chart of initiative ratios and the pattern of judgmental variations in the
way of overestimations and underestimations of performance. A suggestion for activities
coming from any member may be kicked around among the group. Even if it is not initially
addressed to the top position (leader), but to middle position members or lieutenants, it will be
kicked around until a nod expressing approval or, at least, no disapproval from the top position
member (leader) is perceived.
(c) Sociometric data (Note 4): Sociometric data obtained from the subjects themselves along
various dimensions (popularity, initiative, degree of service for the well being of the group, etc.)
will be significant indices in terms of relations perceived by the group members themselves.
The sociometric indices (looking from within) should give very much the same trend as those
represented in the ratings, frequencies, and charts obtained through observational data
mentioned above. We shall consider this hypothesis verified only in cases in which there is a
high degree of correspondence between (a) observational, (b) sociometric, and (c)
experimental indices.
(d) Experimental indices to be obtained through laboratory-type judgmental experiments
introduced at this point: Recent findings which indicate the feasibility of measuring attitudes and
other motivational components through perceptual and judgmental [p. 43] indices suggest that
the reciprocities developing among members of a group as status and role relations will be
reflected in the differential ways group members perceive and judge one another. One index of
these differential judgments as a function of relative statuses or roles will be based on the
tendency to expect higher or lower performance in activities engaged in by members occupying
various status positions. (Differential expectations proportional to status positions occupied.)
Relative over- and underestimates of performance in experimentally introduced tasks may be
utilized to measure indirectly the status hierarchy of group members. If this proves to be the
case, such experimental indices can be developed to check the validity of gross observational
findings, and eventually to supplant them. Such an attempt will be made in this study with the
following hypotheses:
If Hypothesis 1 holds, it can be predicted that:
Hypothesis 1 b (Stage 1)
(a) The higher the status of a member in the group, the greater his tendency to
overestimate his performance in an activity the group engages in.
(b) The higher the status of a member in the group, the greater the tendency of
other group members to overestimate his performance.
(c) The lower the status of a member in the group, the less his tendency to
overestimate his performance in an activity the group engages in.
(d) The lower the status of a member in the group, the less the tendency of other
members to overestimate his performance, even to the point of underestimating it.
This psychological tendency was demonstrated in established informal cliques in an experiment
at the University of Oklahoma carried out as one unit of a research project supported by the
Office of Naval Research (Note 5). However, in that study indices used were estimates of future
performance, whereas in the 1953 study mentioned above direct judgments of performance
were used (Note 6). The experiment to be introduced here follows the [p. 44] procedures used
in 1953 utilizing direct judgmental indices.
Hypothesis 2 (Stage 1)
When individuals interact under conditions stated in hypothesis 1, concomitant with
the formation of group structure, norms will be standardized regulating their
behavior in relations with one another and in practices and activities commonly
engaged in.
This hypothesis is also based on empirical findings by sociologists and on studies of adolescent
cliques, and will be experimentally verified in this study.
The group norms which are standardized will be expressed as attitudes and conforming
behavior of individual members. The production of a set of standards or norms can be verified
by observing the reaction of group members to deviations from it. When there is a norm
regulating the interpersonal relations of in-group members in terms of their established statuses
and roles or regulating behavior in some practice or activity, it can be predicted that behavior by
a group member deviating from the norm will arouse corrective reactions from other group
members. (This applies also to norms regulating behavior toward out-groups which will become
prominent in Stage 2.) The corrective measures or sanctions may range from actual
punishment meted out to the deviate through "silent treatment", scorn, ridicule, criticism,
expressions of disapproval, to amusement, varying according to the importance of the norm
violated, the degree of deviation, and the status of the individual. Facts relating to reactions to
deviation are reported by sociologists and also in the experiment by Schachter and others.
Stages of Intergroup Relations (2 and 3)
As stated earlier in our definition, intergroup relations refer to interaction between two or more
groups collectively or between their respective members. In our study, intergroup relations refer
to interaction between the two experimentally produced groups (as formed in Stage 1) and their
respective members.
Stages 2 and 3 constitute the main stages of this experiment. All of the previous work in Stage
1 (in-group formation) leads up [p. 45] to them. Stage 2 is the tension or friction phase of
intergroup relations. Stage 3 is the integration phase of intergroup relations.
Stage 2: (4-6 days) Intergroup Relations: Friction Phase
Relations between the experimentally produced groups start with a friction phase because the
major problem of intergroup relations today is the reduction of existing frictions between various
groups. For this reason, the phase of friction is preceding the attempt to reduce tension and to
integrate groups into cooperative activities with common goals.
Friction between the two groups will be brought about through the introduction of two sets of
conditions:
(a) During this stage the two groups will be brought into contact in a series of competitive
activities in the form of a tournament of events which will yield cumulative scores with a reward
for each member of the winning team. However, these individual rewards can be obtained only
by being a member of the winning group and cannot be won individually. In other words, in
order to win the award individually the members of each group are to contribute their individual
bits to the winning of the team.
(b) Introduction of situations which will be perceived by one group as frustrating and which will
be perceived as caused by the other group, and not by the camp administration. This was tried
with positive results in 1949. The situations will embody goals which can be attained by one
group and not by the other, in such a way that both groups will perceive the other as an
obstacle in its way to attaining the goal.
In line with the methodological point that the subjects should not perceive this as an experiment
on intergroup relations, conditions set up in Stage 2 and 3 conducive to group frustration and
friction, or to integration as the case may be, must be designed in such a way that the subjects
cannot assign the source of these conditions to the staff. They must be planned in a way such
that it is not possible for group members to ascertain by checking verbally with the members of
the other group that someone (the staff) has been manipulating conditions.
[p. 46] Our general hypothesis is that subjects who did not have appreciable contact with
members of the opposite group during Stage 1 will develop negative attitudes verging on
enmity towards the out-group which is perceived to be in their way for the attainment of goals
shared in common within their group. Negative intergroup attitudes, such as prejudice, develop
whenever any out-group is perceived as frustrating or as an obstacle. (In short, norms
regulating behavior toward out-groups, like social distance norms, are standardized group
products.) Negative attitudes toward out-groups will be generated situationally under these
conditions and will tend to persist even though the individual members in question have not
undergone any special degree of frustration in their life histories. Applying this general
statement to the particular case of intergroup relations in this study, our specific hypotheses will
be:
Hypothesis 1 (Stage 2)
In the course of competition and frustrating relations between two groups,
unfavorable stereotypes will come into use in relation to the out-group and its
members and will be standardized in time, placing the out-group at a certain social
distance (proportional to the degree of negative relations between groups).
Evidence for the rise of stereotypes will be obtained by recording derogatory adjectives and
phrases that are used to refer to the out-group. The specific competitive and frustrating
situations and the activities and verbal utterances relating to out-groups will be noted. If
possible, the frequency of references made to out-groups (positive or negative) and of activities
undertaken relating to out-groups, both in intra- and intergroup situations, should be recorded.
Such conditions, verbal utterances and activities in relation to the out-group constitute the steps
on the basis of which stereotypes are built. In time all members of the out-group will be
perceived in terms of the generalizations encompassed in the standardized stereotypes. This
aspect of our study constitutes a contribution to the formation of norms of social distance
(prejudice) which prevail in social groups. The tendency toward stereotype formation was noted
in our 1949 study and verified in a more systematic way in R. Avigdor's doctoral thesis (Note 7).
[p. 47] In addition to observational data, the rise of stereotypes will be tapped through two
experimental units introduced at this stage:
1. Experimental indices reflecting the reciprocal intergroup evaluations in terms of stereotype
ratings (testing Hypothesis 1, Stage 2). This is essentially the technique used by Avigdor.
2. Experimental indices revealing overestimation of performance of in-group members and
underestimation of performance of out-group members. In this unit a bean-toss contest
between the 2 groups will be introduced. The contest consists of rapid gathering of as many
beans as possible by all members of each group within a brief time period. After the contest,
beans presumably picked up by each member will be projected on a screen, identifying with
each projection the individual who presumably collected them. Actually the same number of
items will be projected each time in the same confined area, the items being spread in
somewhat different arrangements. Estimates of the number of beans will reflect overestimation
of the performance of in-group members and underestimation of the performance of out-group
members. This tendency can be stated in the form of specific hypotheses:
Hypothesis la (Stage 2)
In-group members will tend to overestimate the number of items purportedly
obtained by in-group members and underestimate the number of items attributed to
out-group members.
Hypothesis 1b (Stage 2)
The degree of this tendency manifested will vary according to the status (low or
high) of in-group and out-group members in question.
The feasibility of the two experimental units, viz., assessment of differential judgments of
performance of members of in-groups and out-groups and differential rating of qualities in so
many relevant dimensions, has already been clearly established in an experimental study
carried out in our project (Note 8).
[p. 48] These data from assessment techniques as well as sociometric choices will be obtained
again at the end of Stage 3, and will serve as an index of decrease of unfavorable attitudes
toward out-groups in that stage.
Hypothesis 2 (Stage 2)
The course of relations between two groups which are in a state of competition and
frustration will tend to produce an increase in in-group solidarity.
Increased group solidarity will be revealed in the expressions of glorification of the in-group and
of "feats" of members, especially those of high standing. Increased encouragement of efforts of
in-group members in a way not manifested during the period when the in-group was not in
contact with the out-group will be another indication. Additional behavioral data in support of
this hypothesis will be derived from the experimental units described above.
Hypothesis 3 (Stage 2)
Functional relations between groups which are of consequence to the groups in
question will tend to bring about changes in the pattern of relations within the in-
groups involved.
This hypothesis should hold true for both positive and negative intergroup relations of
consequence. (See also last paragraph of this chapter.) The changes in in-group relations can
be measured in terms of popularity and status of in-group members in various respects. The
degree of consequence of intergroup relations for the group in question can be measured (a)
by the frequency of references to the out-group, and (b) by the amount of planning and activity
engaged in within the in-groups in relation to the out-groups.
One way of testing this hypothesis is through special attention to ratings of status relations
within the groups by participant observers. These ratings should be continued throughout the
intergroup phases with the expectation that some important changes in the functional relations
between groups will produce consequential changes in the in-group structure as stabilized at
the end of [p. 49] Stage 1. The participant observers' ratings will be checked with independent
ratings by other observers in contact with the groups, thus contributing to the reliability of the
data.
The hypothesis is predicted for both parties (winning and losing groups in our study). In the
case of the group suffering defeat the impact of intergroup relations may be to the extent of
disorganization of the in-group pattern, which will be marked by shifts in status positions
occupied by various members.
Related to the above hypothesis is a subsidiary one concerning the functioning of low status
members of the two contending groups. This has theoretical implications in view of present-day
controversies. It can be stated as follows:
Hypothesis 4 (Stage 2)
Low status members will tend to exert greater efforts which will be revealed in more
intense forms of overt aggression and verbal expressions against the out-group as
a means of improving their status within the in-group (Note 9).
An empirical test of this subsidiary hypothesis will be found in observation and comparison of
the hostile and aggressive reactions of low status members toward the out-group (a) when
reacting in the presence of in-group members high in status and (b) when reacting when high
status members of their in-group are not in the immediate vicinity.
Stage 3 (6-7 days) Intergroup Relations: Integration Phase
This stage constitutes the crucial and novel aspect of this study. Deliberately the attempt to
bring about cooperation between groups follows a stage of friction produced between them
experimentally. This should be the attempt in studies aiming at reduction of group tensions.
Production of harmony between groups which are not in a state of tension does not present
much of a problem in terms of intergroup events today. There are various possibilities or
alternatives for the study of reducing intergroup tensions. One alternative could be called [p. 50]
the "common enemy" approach. Empirical evidence and a tryout of this measure as an
expedient manner of reducing post-experimental hostility in 1949 indicates that this measure
can be effectively used. But it implies conflict between larger group units.
Another alternative would be to arrange a series of events in which achievement of individuals
can be made supreme. But this would simply achieve disruption of the in-groups. In terms of
actual happenings in intergroup events, the use of this measure in an experimental study would
be unrealistic and would have few if any realistic implications for the reduction of intergroup
tensions. As noted earlier, actual intergroup tensions take place either collectively between
group units or between individual members of the in-groups reacting in terms of their group
identifications.
A third alternative would be through leadership techniques. With appropriate manipulation this
measure can be made effective. But in actual groups, intrusion of an outside person as a
leader is not a welcome one. In actual groups, leaders, too, are part of the group structure, and
they have to function within certain bounds in whatever initiative they take. For this reason,
manipulation of conditions through leaders who are not part and parcel of the groups in
question has little implication for the state of intergroup relations that actually exist.
Such considerations led to the choice of the alternative to be used in this study. The main
feature of the alternative chosen is the introduction of superordinate goals which are integral to
the situation and which cannot be ignored by the groups in question. The main criteria in the
choice of procedures to be introduced in this integration stage will be that goals of sufficient
strength to the groups in question be superordinate, in the sense that the resources and
energies of any single group will be inadequate for the attainment of the goal, thus creating a
state of real and/or perceived interdependence. Situations will be planned and listed before the
experiment in which such a state of interdependence inheres (a) keeping a sufficient level of
motivation that members of groups are directed toward the superordinate goals, and (b)
introducing a series of stimulus conditions which will make the facing of the superordinate goals
and the modes of their attainment compelling.
[p. 51] The superordinate goals will not be introduced abruptly right after this stage starts.
Initially some contact situations will be introduced. At these occasions the groups will have to
be in close physical proximity under conditions in which expression of their hostility toward one
another will not be very appropriate. Of course, mere get-togethers or contact will not materially
help reduce the friction. The aim of this early period is to create the possibility of
communication between members of the two respective groups. For example, the improvised
birthday of an outsider (preferably a local personage not related to the subjects positively or
negatively in an appreciable way) to which both parties are invited would be an example of
such an occasion. The early phase of Stage 3 will thus consist of occasions that will give the
two groups opportunity for contact or communication.
Hypothesis 1 (Stage 3)
It is predicted that the contact phase in itself will not produce marked decrease in
the existing state of tension between groups.
The persistence of tension will be revealed in reactions showing resistance to cooperation with
the out-group, in spite of contact, and persistence of negative stereotypes. If this prediction
holds, it will eliminate the alternative hypothesis that contact in itself will bring about reduction
of tensions.
After a series of contact situations, a series of superordinate goals will be introduced - - - goals
which cannot help having appeal value to the members of both groups. The following are
examples of superordinate goals inherent in a situation for members of both groups concerned,
the attainment of which is dependent on collaboration on the part of both groups: (a) A project
related to some improvement of the water tank on the hill and the pump near the reservoir,
since the tank provides water for members of both groups. (b) Creating a situation of
interdependence in a joint overnight camp in which members of both groups will need mutual
aid for their meal and sleeping facilities. Probably the increased social suggestibility in new
situations or situations of uncertainty may be utilized to enhance the effects of the conditions of
interdependence. (c) Other examples already suggested by staff members are the possibilities
of [p. 52] utilizing the swimming pool or the truck (which brings their provisions) e. g., having the
truck in a rut deep enough to require the combined efforts of both groups to free it.
Hypothesis 2 (Stage 3)
When groups in a state of friction are brought into contact under conditions
embodying superordinate goals, the attainment of which is compelling but which
cannot be achieved by the efforts of one group alone, they will tend to cooperate
toward the common goal.
Hypothesis 2a (Stage 3)
Cooperation between groups necessitated by a series of such situations embodying
superordinate goals will have a cumulative effect in the direction of reduction of
existing tensions between groups.
Even though the groups are brought into situations which permit communication between them
and then situations requiring their collaboration toward a common goal, the effects of friction
produced in Stage 2 will tend to persist, along with the by-products of this friction. One of the
indices important in the study of the changes in this stage, in addition to observational data
giving a gross account, will be the decrease in expressions of resistance to collaboration with
the out-group, which will be strong at first.
Observational data will be collected in the mess hall and other situations involving choices (of
seating arrangements, etc.) to check the extent of intermingling among members of the two
groups.
Another way of gaining evidence of reduced tension will be a decrease in the actual use of
derogatory terms and expressions toward the out-group. After the series of superordinate goal
situations have exerted a cumulative effect, the rating of relevant stereotypes will be repeated.
The "bean toss" experiment or a similar procedure will be applied here if it can be carried out
without spoiling the flow of the interaction process.
Toward the end of Stage 3 sociometric choices will be [p. 53] obtained again. It is predicted that
in comparison to those obtained at the end of Stage 2 there will be a marked increase in
choices of out-group members.
As predicted in Hypothesis 3 (Stage 2), intergroup relations developing in interaction directed
toward superordinate goals will also tend to bring about changes in in-group relations. As in the
case of the friction phase (Stage 2), proportional to the demands for intergroup cooperation,
there may be changes in in-group structure. A special note should be made here of those who
are contributing more to intergroup cooperation, e.g., lieutenants who exhibit strivings toward
still higher position in the in-group structure and those in marginal roles. Effective cooperation
will be brought about when high status members or members on the move to higher status
through activities in the area of intergroup relations take a hand in (a) initiating in-group moves
toward cooperation and (b) in participating in intergroup communication related to
superordinate goals.

asking the same or similar questions within a 3-week period might appear repetitious (if not
suspicious) to the subjects. Therefore, in line with our main concern not to clutter the natural
flow of the interaction process, it was decided prior to the actual start of the experiment to
restrict sociometric choices to the intergroup stages (2 and 3) and forego them at the end of the
in-group stage (1).

9. This hypothesis does not imply that high status members will not initiate and actively
participate in intergroup conflict. In line with one of the major tenets of Groups in Harmony and
Tension (op. cit.), intergroup behavior in conflict or cooperation consists mainly in participation
in the intergroup trends of one's group. A line of activity in positive or negative intergroup
relations will be ineffective unless high status members either take a lead, join or assent to the
developing intergroup trend. If they stay in the way o fan unmistakable trend in intergroup
relations or deviate from it markedly, the consequence will be sinking in the group hierarchy
(See Hypothesis 3, Stage 2).
[p. 56] CHAPTER 3
Role of Staff, Subject Selection, Experimental Site
As specified in the statement of the approach, hypotheses and general design (Chapter 2), the
distinctive feature of this study is that subjects interact with one another in activities that appear
life-like to them in a natural setting - without being aware that they are being observed while
interaction is going on. Therefore, it becomes essential to make explicit (A) the special role of
staff members in experimentally introduced problem situations, (B) the criteria observed in the
selection of subjects in order to insure adequate testing of hypotheses, and (C) the
considerations which determined the choice of an experimental site.
A
Role of Staff Members in the Introduction of Experimental Conditions
The points covered in this section were instructions given the staff members prior to the
experiment. They are presented here in essentially the same form.
In every step of the work it will greatly help coordination of efforts if all participating staff
members in the camp realize at every moment that the camp is not one in the usual sense, but
is set up as a research project to test definite hypotheses pertaining to group relations, with
emphasis upon the intergroup phase. The main features are stated in the outline giving
approaches, stages, plan of study and methodological considerations. Conditions and activities
are introduced with these objectives in mind (see Chapter 2).
Utmost care will be exercised in ruling out all influences in word, deed, or use of various
procedures which are not specified in the methodology and specific characteristics stated for
conditions introduced for each stage. No activity is to be initiated, sponsored or encouraged
which is not in line with the main criteria specified in the study plan as appropriate for the
particular stage at the time. The behavioral effects are to be the outcome of the deliberately
introduced conditions and not of verbal means or other usual camp practices.
[p. 57] Therefore, do not use verbal means to influence subjects, do not take initiative to
introduce activities on your own accord, and do not try to counsel campers individually. Of
course, this does not mean a "hands off" or non-direction policy in any matter which even
slightly concerns the whereabouts, safety, health and well being of the campers concerned.
No staff member is to be a leader to the boys during any stage of the study in any of the
various activities which are introduced after careful consideration in line with the criteria and
hypotheses. In the first stage, every activity is introduced because it is considered to be
conducive to interaction among the campers, from which a pattern of status (role) relations,
including the leader position, is expected to emerge. You may have to give advice when asked
and institute controls when necessary to maintain order, but please refrain from giving direction
and initiating action in relation to problem situations. Initiative should come from the subjects
under the specifically designed problem conditions of each stage. After they start along some
line of action, give them help to carry it out, but do not put yourself in the foreground of on-
going activities.
When a problem situation is introduced which demands planning, discussion and execution on
the part of the subjects, utmost care should be taken not to show any partiality or preference
and not to assign any single camper to take the lead. If the experimentally introduced situation
involves common appeal value (motivation), the lead will naturally evolve in the interaction
process among the participating campers.
Attention should be especially called to the fact that the participating campers will at times turn
to you, as adults, for approval or sanction for carrying out a plan of activity in relation to the
experimentally introduced problem situations. Care should be taken to be responsive to such
queries or appeals. If the proposals do not run counter to health, safety and well being of the
campers, and also if they do not run counter to the criteria specified for the given stage, the
boys should be given opportunity to proceed in the direction of their proposed activity.
There will be times at which an ongoing course of action may not be in line with criteria set in
the study outline. If such a situation occurs it may be suggested to you by the experimenter [p.
58] that a change be made in the ongoing procedures. In the flow of activities it may be
impossible to explain at the particular moment why this suggestion is made. It is expected that
the suggestion will be followed, and the reasons for suggesting the change will be explained
later at a more appropriate time.
It is fully realized that the end results implied in the hypotheses may be secured in a more
short-cut way by using other activities. Activities and procedures introduced in the various
stages, especially in the first stage, might appear drawn-out and round-about. Since these
successive stages are planned after long and laborious deliberation of existing theories and
findings, they constitute an interrelated sequence in the plan of study, and as such, all
successive steps are dependent on each other. Therefore, utmost care should be taken not to
appeal to short-cuts, but to satisfy the sequence as outlined.
In line with the consideration stated in relation to the rise of leadership among the campers, and
of staff not assuming leadership in experimentally introduced conditions, it becomes necessary
for staff members not to exhibit special performance skill which may be conducive to focusing
popularity and leadership on staff members. This is particularly important for Stage 1. However,
it should be repeated that this does not mean that a helping hand should be withheld to the
campers after a line of activity is proposed or initiated by them. In line with this consideration,
do not wear any clothing, especially shirts, which have insignia or other identifying symbols, e.
g., college or camp name. We do not wish subjects to adopt names or associations through
adult leader-identification. Do not introduce to the campers nicknames, catchwords, slogans in
a way which may cause them to be standardized by the subjects.
All the reports concerning verbal or behavioral observations should be written independently
and not as a consequence of discussion with any other staff member. All ratings should also be
done independently. Particular care should be taken to observe this procedure in order to
secure reliability of results.
In the ongoing activities there is the possibility of an infinite number of events which can be
observed and recorded. Therefore, please have the hypotheses for the given stage focal in
your mind so that the observations will not be hodge-podge, [p. 59] but relevant to the
hypotheses in question. As long as any behavioral items are relevant to the hypotheses, either
validating or invalidating the hypotheses, utmost care should be taken to have all of them
included. It may not be possible to record all relevant items of behavior, but indisputable
recurrences of behavioral items should be recorded.
B
Subject Selection
Since the hypotheses to be tested require that the behavioral trends and products in in-group
formation and the development of positive and negative relations between the groups be
outcomes of experimentally introduced conditions and interaction processes within them,
certain strict criteria for subject selection were necessary. The criteria that were adopted
stemmed from the basic consideration that in-group formation (Stage 1) and the development
of negative and positive relations between in-groups (Stages 2 and 3) should not hinge upon
similarities or differences in sociocultural background or distinct differences in personal
backgrounds and adjustment of the individuals composing the experimental groups. Therefore,
homogeneity of subjects as to sociocultural and personal backgrounds was the guiding
determinant underlying the establishment of criteria for subject selection.
Subjects were to be normal, well-adjusted boys of the same age, educational level, from similar
sociocultural backgrounds and with no unusual features in their personal backgrounds insofar
as extreme or prolonged frustrations, broken home life, etc. were concerned. Any potential
subject who did not appear normal in terms of these general criteria and the more specific
characteristics outlined below was excluded. This meant elimination of all "problem" boys, and
of boys who might have suffered unusual degrees of frustration from inadequate sociocultural
and personal backgrounds. Equally important was that subjects should not have prior
acquaintance before the experiment started. Otherwise it might be said that existing friendship
ties influenced in-group formation (Stage 1), and the resulting groups could not be attributed to
the experimental conditions introduced. Special precautions, outlined below, were taken to [p.
60] insure that subjects were not acquainted prior to the experiment.
Selection of subjects who met the criteria represented one of the prerequisites for the success
of the study. Without adherence to such basic criteria in selecting subjects, many of the
necessary conditions presented in Chapter 2 could not have been satisfied. Sociological,
psychological, and physical specifications were also set up for subjects in order to insure
healthy and well adjusted boys with athletic and other skills sufficient for full participation in the
camp activities, which were to be introduced in line with experimental considerations.
More specifically, subjects were to be of established Protestant families (not new in the area),
of middle socioeconomic class, living with both parents. (Children from broken homes and
foster homes were not accepted. )
Psychological manifestations which precluded the selection of a given boy were any signs of
severe homesickness, social isolation, enuresis, failure of one or more grades in school (i. e.,
subjects had to be of normal educational standing in relation to chronological age), abrupt
changes in school performance, temper tantrums, running away from home or truancy from
school.
All subjects were to be of normal physical development, and possess no physical deformities or
impairments which would limit their participation in the athletic activities that were to be
introduced for experimental purposes.
In interviewing parents and teachers and examining school records, information was gathered
on certain skills and abilities of each boy that might enter as important factors affecting status
positions that would evolve in the interaction at camp. The athletic interests and proficiency of
each potential subject were ascertained, as well as musical ability and skit skills, previous camp
experience, popularity and number of friends of the boy, membership in youth organizations,
etc. In addition, data on attitudes of parents toward the son and his friends, condition of the
neighborhood in which the boy lived, how long the family had lived in the area, size and
condition of the home and its furnishings, make and model of car were secured.
Methods of selection: As mentioned above, one of the most [p. 61] important criteria of subject
selection was that the boys not be previously acquainted with one another. Thus the friendship
patterns and intra- and intergroup relationships formed in the experimental setting could not be
attributed to existing acquaintances and friendship preferences brought to the experimental
situation. This consideration dictated even the city from which subjects were selected. It
required a city of sufficient size to have enough schools for children of the appropriate age and
grade levels that only one boy could be selected from each school, thus reducing the likelihood
of prior acquaintance. Oklahoma City has this many schools, and it was from this city that all
the subjects were selected. (Using this method it was necessary to eliminate six boys from the
final subject list because they were acquainted with others previously chosen.)
In order to adhere to the criteria as effectively as possible, a rather painstaking procedure was
followed in picking out potential subjects and in the final selection of experimental subjects. The
city was divided into 3 areas, each containing roughly an equal number of appropriate schools.
Each area was assigned to the one of 3 interviewers who knew best that particular section of
the city. Schools from sections of the city which had very high and very low income families in
large numbers were eliminated from consideration.
In order to get best access to school records and to be permitted freedom in observing potential
subjects at first hand in the school situation, the principals of appropriate schools were
contacted. After presentation of credentials from higher school authorities, a brief explanation of
the purpose of the visit was given. It was explained to the principal that an experimental camp
under the auspices of the University of Oklahoma was being conducted. The announced
purpose of the camp was the study of interaction in group activities within teams and between
teams. The statement of purpose was informally worded but uniform. It was pointed out that
one of the main things that would be studied was how team members assumed and carried out
initiative and responsibility under adult supervision, what would be the attitude of the boys as
they participated in activities toward common goals they wanted to attain and also the attitudes
that would occur when they competed with another bunch of boys. It was explained that
another item for study was how the boys take it when they win or lose in various activities,
when things are [p. 62] not going their way, when they feel others are being good or bad sports
or unfair, when situations are felt as more or less frustrating, as well as how the boys pull
together and cooperate toward common goals.
In order that school principals and teachers would have little opportunity to recommend favorite
boys for the camp, the interviewer explained to the principal that he would like to go out on the
school yard where the fifth graders were playing so that from first-hand observation he could
pick out some candidates who best seemed to meet the criteria. This served the dual purpose
of allowing first-hand observation of the boys in usual circumstances of interaction by observers
who knew the specific criteria for selection of a boy, and preventing the principals and teachers
from trying to have their favorite boys chosen.
The observer then went to the playground, and when he saw a boy that seemed to meet the
criteria he asked the name of that boy from the playground supervisor. At all times the
interviewer tried to be as inconspicuous as possible in order not to arouse too much curiosity
on the part of the boys. After getting the names of from 5 to 10 candidates who seemed to
satisfy the criteria best, the interviewer then found out all he could about each of these boys
from the playground supervisor. Then he went to the homeroom teacher (if he or she was not
the playground supervisor) and obtained school records and further information on each boy.
From school records, information was secured concerning I.Q., grades, adjustment in school,
social attitudes, and from the teacher, the boy's relationship to teachers and to other children,
status, popularity, and membership in school cliques. The 5 or 6 potential subjects who
remained after this first screening procedure were ranked by the interviewer in terms of the
extent to which they satisfied the criteria.
The next step in selecting subjects was to contact the parents of those boys who best met the
criteria up to this point. All the parents were met by the same individual, the one who was to
appear at the camp as the camp director in the eyes of the boys.
This policy was followed so that when subjects were divided into two groups, neither of the
participant observers (who had served as interviewers of teachers) would have a particular
personal preference for any given boy, that boys in neither group would go to camp already
knowing their participant observer, and that [p. 63] boys in neither group would know the
participant observer of the other group when the two groups first came into functional contact
(Stage 2). (The participant observers appeared to the boys at camp as senior counselors.)
Parents were contacted in the order that their sons were ranked by the interviewers in terms of
the criteria. In interviewing parents, the same explanation of the purpose and aim of the study
was given as had earlier been given school principals and teachers. It was stressed to the
parents that no visiting of the boys would be permitted. The explanation given was that such
visits would contribute to problems of homesickness which would be detrimental both to the
enjoyment of the boys at camp and the success of the study. They were also told that there
was a nominal fee (twenty-five dollars for the entire period) and that a doctor's examination and
permission for the boy to participate in all camp activities would be required, in addition to their
own permission. (The fee, which was a nominal device for making mutual commitments, was
lowered for a few boys who met the criteria but to whose family this seemed a sizable
expenditure for recreation.)
Altogether roughly 200 names of potential subjects were obtained in the manner described
above. Of this number, school records and interviews with homeroom teachers were completed
for almost half. In the selection of the final experimental subjects the parents of approximately
50 boys were contacted and/or interviewed. The original goal was 24 subjects who met the
criteria in every respect, but strict adherence to the criteria resulted in the procurement of 22
experimental subjects. Altogether more than 300 hours were spent directly in selection of
subjects, in addition to the numerous hours spent in establishing criteria and setting up the
procedures.
Final experimental subjects: The 22 subjects who were finally selected were relatively
homogeneous in terms of the major criteria outlined above. All were from established
Protestant families. All were well adjusted both in school and at home, according to
observations, school and home interviews. According to school records, all the subjects were
doing average or above school work (none was failing or had a history of failures). All were fifth
graders about eleven years old who were promoted to the sixth grade for the next school year.
This age level was [p. 64] selected so that none of the boys would have reached puberty, which
could have been an important additional factor in determining the status positions that would
emerge in group interaction. All were taken from the same grade for similar reasons, namely,
that no one should have a status advantage because of a more advanced grade in school.
The median income of the subjects' families was $4,900 a year. The income of eleven families
was below $5,000, the lowest being $3,200, and only two were (slightly) above $7,000.
However, on the basis of occupation, education, home, neighborhood, etc., the subjects'
families can be characterized as "middle-class" on the whole.
The average (median and mean) age of subjects was 11 years and 1 month. Five boys would
have their 11th birthdays shortly after camp, and only one would be 11 well after the school
term started. One boy had reached 12; all others were eleven.
I.Q.'s were available for 18 of the 22 boys. The median I.Q. for these 18 boys was 112. Four
boys had I.Q. scores between 90 and 105, and only one above 120. Thus, by and large, these
boys were above average in intelligence test scores, 11 scores of the 18 available being
between 110-120. The boy with the lowest I.Q. was doing satisfactory work in all school
subjects and was rated by his teacher "at the low end of the upper one-third" of his class in
school achievement.
The boys did, of course, differ within limits in size, manner and other personal characteristics,
ability in various games, hair coloring, etc. However, these individual variations were within the
range of normality for boys in the schools, grades, neighborhoods, types of families, etc., which
had been chosen in terms of the criteria. Home and school interviews and school records did
not offer a critical indicator of status that would be achieved in the new camp situation. The
status structures developing during in-group formation and the nature of relationships between
the groups as they came into functional contact during the experiment cannot be accounted for
on the basis of differentiation of individuals or between clusters of individuals based on
characteristics stemming from different sociocultural backgrounds, from atypical personal
backgrounds, or previously existing relationships.
[p. 65] In dividing the 22 subjects into 2 groups of equal size prior to the experiment, great care
was taken to match subjects signed to the 2 groups, so that they would be composed as
similarly as possible. Matching was carried out in terms of certain personal characteristics of
the boys. Considered in their order of relevance for interaction in the camp situation, they were:
height; weight; sports ability (general); sports skill (special); popularity (in neighborhood and
school groups); other skills relating to camp such as musical and skit skills, cooking ability, etc.;
swimming; and previous camp experience. After the two groups had been matched as closely
as possible in terms of these characteristics, a coin was flipped to determine which group of
subjects went to what participant observer. This was a final precaution to rule out possible
effects of any personal preferences of participant observers for particular boys.
C
Experimental Site
Certain characteristics were necessary in the experimental site. It had to provide isolation from
the outside world during the experiment so that extraneous influences would not enter and the
results would be mainly a function of conditions deliberately introduced. There had to be
separate facilities for two groups to be handled in isolation from each other during in-group
formation (Stage 1), so that group formation would be the consequence of conditions
introduced and interaction within the in-group, without contact with an out-group. Also, the
physical characteristics of the camp and surrounding area had to be of a nature allowing
flexibility in choosing and planning in-group and intergroup problem situations by providing
numerous circumstances conducive to the arousal of common goals of high appeal value and
to a variety of activities.
The site finally chosen after inspection of a number of camps was a densely wooded area in the
Sans Bois Mountains of southeastern Oklahoma about seven miles north from the small town
of Wilburton which is on U. S. Route 270. This is a 200 acre Boy Scouts of America camp
which is completely surrounded by Robbers Cave State Park (See Figures 1 and 2). It was
available exclusively for purposes of the experiment for the three week [p. 66] period. The
nearest large town - McAlester, Oklahoma - is about 40 miles distant.
Since terrain and facilities were utilized as part and parcel of stimulus conditions throughout the
experiment, it will be helpful to specify them. For the readers' convenience, places of functional
importance in in-group and intergroup activities are indicated on the accompanying map at the
end of this section which gives approximate distances between points mentioned (Figure 2).
Effective isolation of the camp was made possible by a surrounding fence with "Keep Out" and
"Restricted" signs posted and by the heavy foliage which screened the camp area from a park
road running some 100 yards outside the fence. Functional isolation of the groups from each
other during in-group formation was made possible by the terrain of the area, and by careful
timing of their coming and going. The cabin used by each group was beyond sight and hearing
distances of that of the other group, and duplicate facilities were available for both groups (bath
houses, swimming, boating and campfire facilities, etc. ). Both groups used the mess hall which
was about equidistant from the two cabins. However, it was not visible from the cabin at the
south end of the camp because of a hill, and its entrance could not be seen from the north
cabin because of intervening buildings and trees.
Because of the characteristics of the experimental site itself, the surrounding park, and the
mountainous areas within a sixty mile radius, it was possible to plan activities of high appeal to
the subjects for both in-group and intergroup stages. Within easy walking distance from each
cabin, and in opposite directions, were swimming, boating and camping areas which were
available for the exclusive use of each group. Campfires could be held near the cabins, at the
"hideout" areas, or in a natural stone corral which was near Robbers Cave on the hill above
camp. A very isolated reservoir in the hills above the camp supplied its water and offered
facilities within hiking distance for overnight campouts. An athletic field was located across the
park road, outside camp property, and nearest to the north cabin. The field was accessible by
two different routes for the two groups. Thus, when and where contact between groups would
take place during competition situations could be controlled.
[p. 67] Lake Carlton, a part of the state park area, was located about three miles from the
experimental site and provided excellent swimming and picnic facilities. A number of camping
areas were located on lakes and rivers within 20 to 60 miles of the camp. These could be used
to advantage in increasing interdependence of the groups (Stage 3) through cutting off their
usual sources of food, housing, etc. Of these various possibilities, Cedar Lake, about 14 miles
from Heavener, Oklahoma and 23 miles from the Arkansas state line, was utilized in Stage 3.
The campsite (cabins, mess hall, etc.) is situated on the flat stretch of land below this ledge. [p.

[p. 69] CHAPTER 4
Experimental Formation of In-groups
Revealed Through Appropriate Attitudes and Behavior
Overall Considerations Common to All Three Stages
Before summarizing Stage 1, a few considerations common to the procedures of all the three
stages should be emphasized. One fact that will stand out in the rest of this report is that the
stimulus conditions, the activities necessitated by them, and places in which they are carried
out, are numerous and varied. It may be easy, therefore, to lose sight of the systematic
rationale on which all three stages were based in the kaleidoscope of numerous and varied
events.
The fundamental aim of the procedures in the experiment is to build up an interaction process
which is perceived by the subjects as part and parcel of the circumstances in which they are
living. The flow of interaction is followed from day to day in a longitudinal way. The interaction
among subjects on a given day at a given stage of the experiment is not a discrete and
unrelated event, but is built up on the basis of interactions on the previous days and is
functionally related to future events. A serious concern over validity, viz., a concern that events
occurring in this study have some point of contact with their counterparts in real life, forced the
adoption of this fundamental approach upon us. Group behavior, in intra- and intergroup
relations, is not a transitory affair. Group structure itself is anything but ahistorical. Therefore,
step-by-step tracing of group structure and its norms is essential in pin-pointing the factors that
enter into the shaping of group behavior now.
Groups in actual life do not ordinarily strive toward goals which are furnished by the instructions
of an outsider. Group goals exist or arise because group members are situated in a certain
place and time, under given circumstances, and because the pattern of interaction is what it is.
All of these determinants have specific implications in relation to the state of motivation of
group members.
Therefore, it is decidedly unrealistic in experiments on [p. 70] group relations for the investigator
to introduce any old task and have groups work on it at intervals in an interrupted way under
certain types of "leadership," and then to draw cut and dried conclusions concerning group
behavior on that basis. There is abundant evidence in the sociological literature of small groups
which one might do well to remember. In this literature, time and again, we find individuals in
whom common motives or deprivations are generated (because they are where they are and
are caught in the particular set of circumstances) forming groups, developing strong in-group
attitudes, strong in-group solidarity and responsibility (at times, to the point of sacrifice of no
mean proportions) without the benefit of this or that type of adult "leadership" from a personage
who is not himself an integral part of the group. There are cases of groups formed in actual life,
without the benefit of a benevolent, permissive expert, which have a strong structure, an
intense sense of belongingness and solidarity. These properties may not develop in groups
which are under the "leadership" of an outsider, no matter how skilled and expert he may be.
For these reasons, in each of the three stages of this experiment, a series of goals and related
tasks were introduced which were derived from explicit preferences of the subjects themselves.
Verbal instructions as a method of introducing goals were avoided as much as possible, the
aim being instead to create situations in which the subjects would immediately perceive a
problem situation or a possibility for attaining some desired end.
Similar comment applies to procedures for the study of a group discussion and techniques of
problem solving. Once the group members face a problem situation of strong appeal to them,
they do not have to be told to gather around and discuss their common plight or desire. You
cannot stop them from being preoccupied with the problem at hand nor from making it a focal
concern - and discussion does not stop there. Discussion necessarily continues, or even takes
place simultaneously with active search for ways and means of doing something about the
problem. The procedures in every stage of this study, therefore, have involved choosing the
terrain, time, stimulus conditions, equipment and words conducive to the arousal of a problem
situation which implies common goals. This, we repeat, will lead to dissuasion, planning,
searching for appropriate means and tools, and execution of planned lines of activity.
[p. 71] Individuals who are immersed in their plight or problems in earnest are prone to be
irritated by cold-blooded nosiness in their affairs by outsiders, not to mention having to put up
with doing this or that extraneous thing for the benefit of the tape recorder or the convenience
of the experimenter. Therefore, in the study of group interaction, we insist on observation by
persons who are part and parcel of the situation, and that they not be caught by the subjects in
the act of observing. By following the participant observer technique, in which no word was
written in the presence of the subjects, we may not have obtained all relevant events. However,
in return, we gained free and unsuppressed recurrence of behavioral items which will stand out
in a striking way for any observer.
In short, our fundamental approach has been carefully to introduce a number of problem
situations appropriate to the characteristics of the stage in question, and to leave the ensuing
activity in word (discussion) and deed to the subjects themselves as much as possible. We did
not think that reliability would be insured through repetition of the same problem situations. This
would have led to boredom and/or suspicion on the part of the subjects. Instead we followed
the policy of introducing varied problem situations all of which had the common property of
satisfying the main conditions for the stage in question. Pitching a tent to sleep in, preparing a
meal when hungry (with ingredients in bulk form), building a rope bridge cannot be carried out
by one person alone, but require cooperation of all group members. Therefore, these activities
satisfy the main characteristics of conditions for Stage 1, even though these varied activities
require greater or less exertion from different groups of muscles.
We feel that this brief mention of the procedural considerations common to all the three stages
will be incomplete without calling attention to the very bounds within which the interaction was
taking place and activities were being carried out. At all points of this report, it should be kept in
mind that the subjects came from a given sociocultural setting which determined the overall
properties of their interaction in in-group and intergroup relations (Chapter 2). The experimental
conditions were effective within these bounds. Without keeping this in mind, it would be difficult,
for example, to understand:
(a) why both groups were eager to challenge each other in [p. 72] a competitive activity the
moment they learned of the presence of another group in the camp (end of Stage 1);
(b) why, after hurling unpleasant words at each other at the first competitive encounter, the
winning team would give three cheers for the losers during the first days of Stage 2.
Even in in-group activities, the techniques and methods in problem solving may be greatly
influenced by the particular structure and norms of the group in question and by properties and
values of the sociocultural setting. Certainly these methods vary from culture to culture.
Therefore, no special emphasis has been placed on whether a group adopted this method or
that method of problem solution. In certain cultures, there would probably have been a greater
tendency to resort to the decision of a leader or an authority figure than found here.
The second point which must be mentioned in this matter of the bounds for the interaction
process is the presence, words and actions of staff members. The main function of counselors
and other staff members was deliberately specified to be that of producing problem situations
through setting appropriate stimulus conditions at appropriate times, in terms of the
motivational state of the subjects at the time, using verbal prompting as little as possible (see
Chapter 3).
An important factor in initiating or continuation of activity is the presence, words and deeds of
staff members (junior counselors, participant observers and other camp authorities). Even
seemingly unimportant silence, or prompting, or negation during interaction in problem
situations may have great influence in the direction activities take. We cannot say that we
succeeded in eliminating this factor altogether in spite of all our efforts. The subjects always
knew, whether they were conscious of it all the time or not, that staff members were there; that
they could always appeal to them; and that they represented the ultimate authority in setting
bounds. For example, at the time of exhibition of courage and bravery while engaged in group
activities, the whole psychological trend might have been reversed if the subjects had been
deprived of the security that the staff members afford.
[p. 73] Another factor that sets bounds to the particular type of interaction among subjects is
their age level. Eleven year-old boys are certainly not to be taken as adults, nor their behavior
in groups as identical with that of adult groups. Neither can the issues conducive to friction and
cooperation between two groups of 11-year-old boys in an experimentally conducted camp
situation be the grim and lasting problems that sometimes prevail between groups of adults. On
the other hand, at this age level, ego functioning (hence group relatedness or identification) is
carried on at a conceptual level. It would have been preferable to carry out the experiment with
older subjects if that had been feasible. Originally, our hypotheses were derived from a survey
of literature on in-group and intergroup relations of older subjects. Validation of these
hypotheses with subjects of the age level used here should have implications for future
experiments with older subjects.
Note on collection of data: A special point was made that the participant observers always be
close to their respective groups. Each participant observer spent at least twelve hours a day in
observing their respective groups. Making allowance for the fact that one group came to camp
one day earlier, the hours spent in observation of each group by the participant observers alone
(not counting observation time of other staff members) were 240 and 252 hours respectively, or
a total of 492 hours for both groups. The participant observers jotted down in short form outside
of the vision of subjects as soon as possible after an event occurred, then expanded their notes
during the afternoon rest period and after the subjects went to sleep around 9:30 P. M. At that
time, a complete report of observations for the day was written and ratings made by the
observer. An additional source of data at some crucial points consisted of answers and
reactions of subjects about events in response to naive questions by staff members who could
appropriately ask such questions because they had not been present when the events
occurred.
In addition to the observational reports, 1200 pictures were taken during the three-week period.
In order to attract as little attention to the picture taking as possible, staff members exhibited to
the subjects as they arrived at the bus which would take them to camp that they were shutter-
bugs - conspicuously taking pictures of every conceivable object in the vicinity. Conversations
were recorded by a hidden tape recorded at some choice points without the awareness of the
subjects. Plans for portable [p. 74] recorders which were to be used in a candid way
unfortunately did not materialize because our order for two portable recorders could not be
filled at the proper time.
Experimental Formation of In-groups
Stage 1
The focal concern of the present study is intergroup relations. Extrapolations from interpersonal
relations, or even from in-group relations, have given us inadequate accounts missing crucial
properties which make the topic of intergroup relations so vital today (Note 1). Therefore,
intergroup relations are studied in this experiment as relations between actual in-groups and
their respective members.
Rather than selecting existing groups, whose structures and norms were already formed and
who had perhaps established norms toward various other groups of peers in prior intergroup
contacts, the experiment started with the formation of in-groups among individuals who were
not previously acquainted through controlling the conditions in which they interacted. It will be
remembered that the members of each group were homogeneous in terms of sociocultural,
economic, educational backgrounds, etc. The rest of this chapter is devoted to a summary
account of the formation of group structures, norms, attitudes manifested in relation to other in-
group members and toward places, persons and objects with functional relevance to their
activities.
Observation and ratings of in-group structure and functioning did not stop at the end of Stage 1,
which was devoted to its study. Throughout Stage 2 (intergroup friction) and Stage 3
(intergroup integration) data on in-group structure and functioning continued to be collected.
Reciprocal effects of in-group and intergroup relations were one of the focal points of
concentration throughout.
Since functional relations between groups would certainly affect the formation of in-groups and
their structures, the two groups of subjects were kept apart during Stage 1. Until the last days
of that stage, at no time did the groups have contact with one another.
[p. 75] One group was brought to the site on June 19, 1954, and the other on June 20, at a time
when the first group was out of the immediate camp grounds on a cookout. Because of the size
and layout of the site, it was possible to center activities of the two groups in different areas
simultaneously (see Chapter 3, C. Experimental Site). Separation was accomplished through
staggering scheduled activities (e. g., meals) for the 2 groups and careful timing. Toward the
end of Stage 1, in preparation for the period of intergroup relations to follow, subjects were
allowed to discover definitely that there were 2 groups in camp.
To test our hypotheses for Stage 1, conditions consisted of activities and problem situations (a)
embodying goals with common appeal to all of the individuals and (b) requiring interdependent
cooperative efforts on the part of these individuals. The characteristics of conditions for this
stage were set up on the basis of the period of in-group formation in the 1949 and 1953
intergroup studies (see Chapter 2).
One form of activity which appealed greatly to every subject was competitive team sports,
especially baseball. At one time or another, all asked about the possibility of playing baseball
with another group, some even bringing this up on the bus going to camp. Since competitive
sport between teams composed of members of the same group could not be considered an
interdependent, cooperative activity, team play was not included in the activities of Stage 1.
Delay of competitive games between teams until Stage 2 (intergroup) was accomplished with a
great deal of planning through other activities, many of which were highly desirable to the boys,
"work-up" games in which group members rotated positions and exhibited their skill, and the
apparent lack of another team to play.
Following a summary running-account of interaction events in each of the two groups, evidence
related to the hypotheses for Stage 1 will be reported briefly.
For the sake of continuity and clarity throughout this report the groups are called the Rattlers
and the Eagles. However, it should be kept in mind that the groups did not have names when
Stage 1 started and only adopted these toward the last days of the stage. For the Rattlers, who
arrived first, Stage 1 lasted 8 days, and for the Eagles 7 days.
[p. 76] Proper names used in no case correspond to real names of the subjects.
Rattler Group
Subjects were picked up in Oklahoma City at two stops. Since one boy was late at the first
stop, the waiting period at the second stop (1/2 hour) permitted the formation of a friendship
cluster of 4 boys which was evident on the bus in seating arrangements, a paper-wad game,
and the inquiry if "us south-siders" could stay together. Conversation on the bus concerned
fathers' occupations, respective schools and ballteams, possessions, and favored activities.
At camp, boys were allowed to choose their bunks. The "south-side" boys chose neighboring
bunks. At the campfire after supper, the boys selected Brown (the largest boy in the south-side
clique and in the entire group) to make out a list of swimming buddies in anticipation of their
most preferred activity.
At breakfast on Day 2, saying grace was proposed and Brown did it. After the boys arranged
church services, Simpson (who had been active on the bus) led group singing, although
opposed by "south-siders. " On a trip to Robbers Cave, Brown and Simpson were in the lead.
After lunch, the boys "discovered" the swimming hole upstream and the campsite. They
suggested improvements (such as a rock approach and diving board) and began work on them
after a swim. Brown directed activity in the water and at work. Mills organized a rock-moving
chain which was effective. The boys decided to stay at the hideout for supper and were
furnished hamburger and other bulk ingredients, necessitating interdependent specialized
efforts by all, which Simpson directed - cutting the watermelon himself. They discussed further
improvements of the area, most of the suggestions for improving the area being directed to
Brown.
The next morning a canoe, which had simply been placed near their cabin, was transported by
the boys overland to the upstream hideout, Brown directing the operation and Simpson showing
the path (See Figures, Stage 1). The need for a latrine at the hideout was posed by staff.
Brown handed the shovel to Simpson, [p. 77] and all helped in turn, the smallest boy finishing.
Brown's tendency to play favorites in the use of the boat and in work led Swift (a "south-sider")
to complain, in effect, "We're tired of just doing the things he leaves over."
Mills hurt his toe but did not mention it until it was discovered at bedtime. This incident marked
the beginnings of a norm for being "tough" (not a sissy or cry-baby). Subsequently, injured
members did not complain or cry, desiring to continue even the most strenuous activities if staff
permitted. Related to this norm of "toughness" was group approval of cursing, which became
widespread in the Rattler group. During campfire at Stone Corral, the boys planned an
overnight hike further upstream enthusiastically.
On Day 4 the boys organized transportation of equipment to the reservoir and selected
advance scouts. Brown carried a light load. Mills soon took over leading the party, with
Simpson and Martin doing more than their share of the work. Mills' choice of a campsite was
accepted even by Brown. Mills directed securing water and preparation of food, with various
boys performing specialized tasks. Barton and Hill (low status) tried to climb the dam. Then,
Mills organized this activity into a game with definite order of participation and rules for
maintaining position. The boys started to pitch tents by pairs; but an approaching storm and an
encounter with a rattlesnake posed the difficult problem of rapidly erecting a sturdier single tent,
in which all cooperated.
The next morning the "tough" norm was revealed on the trip home (led by Mills) over hills and
rocks with full packs and with only one rest stop. Upon arrival, beds and personal gear were
found outside the cabin. Staff explained the cabin had been fumigated (an excuse to see how
the boys would re-install themselves). In moving back, Mills chose a bed between Brown and
Newman (the 2 top erstwhile "south-siders"); the other 2 south-siders moved to other parts of
the cabin. The sub-clique was clearly integrated with the rest of the group. Mills put up a "Home
Sweet Home" sign.
Staff at last yielded to the boys' pleas for canteen supplies, requesting that they list only 8 items
on the grounds that the camp could not afford to have left-overs. Agreement on 8 items was
reached, and Mills was selected to announce the results.
[p. 78] By Day 6 the route to the hideout was standard and preferred to an easier one. Boys
planned the activities for the day. Swimming at Camp One (standard name for hideout) was
first. Allen, Barton and Hill (low status) were upset to find paper cups at their hideout (probably
left by the group), speculating with resentment that "outsiders" had been there. Baseball work-
out followed with members accepting decisions of the rest of the group on plays, excepting
Mills who changed a decision in his own favor. During the rest period, Mills started tossing pine
cones and ended up in a tree being pelted by all others and shouting "Where's my fellow men?"
A boy replied, "Look at our leader!" (The "clown" role often kept him in the center of activity.)
A group Treasure Hunt was held by staff in which all members had to be present at the reading
of each note to receive the reward ($10 to be spent as the group chose). Hardball equipment
was chosen, Mills having Martin write what he called "my proposal. " Mills opened nominations
for baseball captain, supporting Simpson (who was selected) and choosing his own position.
Caps and T-shirts were available through the canteen for purchase at nominal cost. Mills asked
if "Tom Hale" (name of the Boy Scout campsite) would be on them. The staff reply was
negative. Harrison (middle status) suggested putting "Robbers Cave Robbers" on them. Later
Mills proposed stenciling "Tom Hale Rattlers" on the shirts, drew a rattler design, and requested
orange and black paint, all of which was approved by the group.
The next morning the boys stenciled shirts and hats with staff assistants. White material
available for crafts was selected by Mills for a flag with the same design. Staff proposed
practice at tent pitching. It was undertaken in disorganized fashion. Baseball practice revealed
stabilization of playing positions.
After supper, the group was allowed to wander within hearing distance of the Eagles who were
playing on the ball diamond. The immediate reaction was to "run them off" and "challenge
them." After this, Harrison (who had had to surrender the catcher's position to Hill because of a
hurt hand) cried bitterly. Hill and Martin comforted him, and he stopped crying when Mills asked
him to read a comic book aloud.
[p. 79] At baseball work-out the next day, the group noted improvements they had made on the
diamond and declared: "Now this is our diamond." The boys revealed a consciousness of the
other group by frequent reference to "our baseball diamond," "our Upper Camp," "our Stone
Corral." That afternoon the staff informed the group that there was another group in camp and
that they wanted to challenge the Rattlers. The reaction: "They can't. We'll challenge them
first... They've got a nerve..." Other activities in which they could be challenged were
mentioned, including tent pitching. Now that tent pitching appeared a competitive activity, it was
enthusiastically supported even by those formerly opposing it. The boys initiated shifts in work
positions which produced an amazing change in execution of the task. All members cheered
the results.
At the hideout, Everett (a non-swimmer when camp started) began to swim a little. He was
praised by all and for the first time the others called him by his preferred nickname. Simpson
yelled, "Come on, dive off the board!" All members in the water formed a large protective circle
into which Everett dived after a full 2 minutes of hesitation and reassurance from the others.
While he repeated the performance, little Barton, a frightened non-swimmer, plunged forward
and started swimming a little too. He was called to the board and he too jumped in. Allen, a
swimmer who was afraid to go off the board, now followed. Harrison, on the bank with an
injured hand, was assured by the others that when his hand was healed they would all help him
"so that we will all be able to swim." This event, which was completely spontaneous, was most
effective in building group solidarity and morale. That evening the boys planned and held an
enthusiastic campfire at the Stone Corral. Group skits were organized by Mills, and Brown
"shone" in an individual act.
Eagle Group
The bus picking up these eleven subjects was on time at both stops so that little prior
interaction was possible. Conversation on the bus started concerning Clark's bugle, which he
played on request. The boys exchanged information concerning schools attended, respective
standings on baseball teams, and families. Upon arrival at camp, free choice of bunks and
seats at supper

Stage 1
[p. 80] was allowed. At campfire, Myers built the fire, then disagreed with others on the proper
method of roasting marshmellows. Craig stopped the argument, saying: "You're not the boss."
Mason asked if they could take down a sign left by earlier campers. One boy proposed "O. U.
Camp" as a name for the spot, but no decision was reached until the next day, when Myers
suggested putting up an O. U. Camp sign as something already "decided."
On Day 2, Clark was last to wake and therefore couldn't play reveille on the bugle. Later in the
week, it became standard procedure for the first boy up to awaken Clark, who then woke the
rest with the bugle. The boys asked to take the canoe placed near their cabin on a hike
downstream after breakfast. Division of labor was complete: 5 boys carrying the canoe, 5
others supplies (including lengths of heavy rope), and one the board and paint for the 0. U.
Camp sign (See Figures). When Davis stopped carrying the canoe, Craig called him into line.
As they prepared to swim at the hideout area, Bryan suggested a bridge across the stream.
After the boys took the initiative along these lines, they were told by staff they could use the
rope for this purpose. During swimming Craig took over the canoe, letting one, then another
paddle and hitting boys who hung on the back. Mason wanted to get in the water to pull a big
rope across for a bridge. All volunteered to help, and this was done through great effort by boys
and staff.
In the afternoon when they returned to the hideout for a swim and supper, the rope bridge was
completed, as agreed, through Mason's initiative. Craig walked the bridge about 15 feet before
falling in, Mason less, and Myers about the same. When Cutler tried, someone said, "He won't
make it very far", and there was amazement when he crossed it. The prediction that Cutler
could not do as well as Craig and the others reveals the development of differential
expectations in line with emerging status relationships within the group. The astonishment at
Cutler's success indicates that some standardization of these expectations had already taken
place on the second day.
When the boys were hungry, Myers ferried them to the opposite bank, making so many
unpleasant comments to the boys that later he heard them discussing him negatively. As a
result, Myers made active efforts to be agreeable the next day.
[p. 81] A large copperhead snake was seen 8 feet away from the campsite. After the staff threw
at it, the boys were permitted to help kill it. They discussed snakes at length during food
preparation. All but one of the boys took over jobs in preparing the meal. After supper a snake
was seen in the water, and several boys said they didn't want to swim there again. The boys
dubbed this place "Moccasin Creek" that night. In spite of the discussion, they returned to the
spot the next morning.
Because the Eagles had 3 possible swimming spots, discussions arose repeatedly during the
next few days about where they would swim. The decision on the third morning was for
Moccasin Creek. Wilson said he heard a rattler everytime they passed a particular spot, which
was christened "Rattlesnake Bay. " Davis proposed that the campfire area across the stream
should be called "Copperhead Hill" because of the snake killed there. These names were used
in all subsequent references to these places. The boys painted signs to label Moccasin Creek
and Copperhead Hill.
Spontaneous discussion among the boys on the need for screens in the cabin found opinion
divided, Craig saying they were unnecessary. A later vote to request screens was favorable,
and when the screens arrived 3 days later, Craig was among the first making immediate efforts
to install them.
At "work-out" softball near their cabin, Mason stood out the best player. Craig and Davis
bawled out Myers for clowning (baseball was serious to these boys).
Since the boys had requested a campout, a hike to the reservoir started on Day 4. The boys
carried 6 small tents, packs, and other equipment. Myers astounding everyone by carrying 3
tents in addition to his pack. Upon arrival, Mason said the reservoir wouldn't be good for
swimming. Three boys who didn't go swimming volunteered to fix lunch. After lunch, Davis
pointed out all of the features of this campsite which were inferior to Moccasin Creek. His
requested vote to return there went 6 - 5 against returning. One by one he persuaded others to
switch their votes to favor leaving. Therefore, after a rest period, Craig directed transportation
of supplies on the homeward trip. When Myers kept the group waiting while he returned for a
forgotten bathing suit, he was pelted with pebbles, but showed no [p. 82] signs of being
disturbed.
At Moccasin Creek, Myers swam without his suit and was christened "Nudie. " (This became
the standard mode of swimming after Mason took it up the next day.) Several staff members
were present at the group's cookout at Moccasin Creek. Craig organized its preparation and
played host. The boys told the staff that Moccasin Creek was several times better than the
reservoir for swimming and camping (which was not objectively true). A song introduced by
Craig on the bus was now called "our song."
After breakfast on the 5th day, the boys were told to select 8 items for the camp canteen, which
they had been requesting for days. Craig and Davis took the lead in making suggestions, and
Craig wrote them down. He accepted Myers' formulation for some terms to make them more
general to cover more items. At softball work-up, Mason, the best player, accepted Craig's
decision that he was "out" at second.
On the group Treasure Hunt, some members waited for Craig and handed him the notes to
read. Suggestions by middle and low status members on how to spend the $10 reward were
rejected in favor of Davis' proposal (hard ball equipment) which was backed by Craig, who
wrote down the decision and told the boys to line up to sign it. After lunch, Craig lectured about
10 minutes on the various baseball positions and who played them.
While screens were being put up on the 6th day, Boyd and Davis (who had shown signs of
homesickness, especially at night) discussed home with Mason, who also became nostalgic as
the conversation continued. Craig, Myers, McGraw and Wilson derided homesickness. Wilson
told Boyd he was homesick because he got too many letters from home (see below).
At lunch it was mentioned that Craig had given each boy a number. During practice with the
new hardball equipment acquired with the Treasure Hunt reward, everyone ignored Myers
when he refused to accept a decision, and simply left to retire from base. Craig was not ignored
when he objected to an adverse ruling, but he gave in with some grumbling. During the
practice, Wilson heard the other group playing at a distance and referred to "those nigger
campers." Cutler asked if the Eagles [p. 83] could play them, and Craig instructed staff to "ask
those campers to play us."
On the last day of Stage 1, staff decided to permit Davis and Boyd to go home, which they had
requested the previous night. These boys had endured intermittent homesickness for several
days. Boyd was occasionally reduced to tears even in the daytime. It was belatedly discovered
that the boy had left a camp the previous summer for the same reason. Had this been known,
he would not have been chosen as a subject. Davis had not been to camp before, and seemed
to become homesick chiefly at night. He often went to Boyd to comfort him, and then ended up
tearful too. His status was high, but had been falling because he wanted to go home. Since the
experiment was not set up to deal with homesickness and it would have run counter to the
design to exert outside efforts to keep individuals in the group, the departure of these 2 boys
was quietly arranged. When the group asked where they had gone, Craig said, "Things are
going to be better around here now." Wilson (scornfully): "They chickened out." Mason: "They
are the only boys who will. " (Mason had not been immune to their talk of home himself on
previous days.)
The group entered enthusiastically into tumbling, wrestling, and tent pitching. They asked when
they could play the other team in baseball, and decided to elect a captain. Craig, who by this
time was clearly leader, nominated Mason and agreement was voiced.
Later in the day, Myers asked if the other group had a name. Staff replied they weren't sure.
Myers commented that his group needed a name. Craig suggested "Eagles." Clark suggested
"Rattlesnake Biters," and then said he didn't like that himself. Craig's suggestion was
supported. Myers said they could make a flag to take on the field when they played. Craig
asked staff to help cut a stencil of "Tom Hale Eagles" to put on T-shirts they had decided to
purchase, and proposed putting an "E" on their caps. Mason said he didn't want his shirt
stenciled, but Craig told him he couldn't play if he didn't do it. At ball practice, everyone
criticized Lane (low status) for not playing well; but nothing was said when Mason or Craig
missed a ball. Craig told staff the group had decided to sleep out in a tent that night.
[p. 84] Summary of Hypotheses and Results: Stage 1
The above accounts of interaction during Stage 1 in the Rattler and Eagle groups hold the pith
condensed from a bulk of observational material, recordings, and pictures. In the following
pages, observational data are considered further in relation to the hypotheses for this stage,
necessarily in highly abbreviated form.
Hypothesis 1, Stage 1
A definite group structure consisting of differentiated status positions and reciprocal
roles will be produced when a number of individuals (without previously established
interpersonal relations) interact with one another under conditions (a) which
situationally embody goals with common appeal value to the individuals, and (b)
which require interdependent activities for their attainment.
Experimental conditions with the above characteristics were varied, requiring more or lees
equipment, occurring only once or being repeated over and over. Many of the specific
conditions for the 2 groups were common because they were introduced deliberately as a part
of the experiment. Among these were the group Treasure Hunts, which required joint efforts by
all members in tracing the path, winning the reward, and in deciding how to use it; another was
the canteen problem which staff posed by limiting the number of items for the much-desired
canteen to eight.
Other conditions satisfying the characteristics of Stage 1 arose in both groups as problem
situations because both groups had similar interests and interaction in each took place in
terrain common to the camp. Many activities were suggested by subjects as pastimes they
especially preferred. To a great extent, subjects were allowed to engage in these at times and
as often as they chose (being limited only by health considerations and the occasional
necessity of temporary postponement to keep the 2 groups separate). Out of these pastimes
preferred by both groups (like swimming, boating, hiking, camping out, baseball) a great variety
of problem situations arose requiring interdependent activities, and many were similar for both
groups. For example, transportation of boats and equipment, planning and [p. 85] executing
hikes, improving swimming places (with rock approach and diving board for Rattlers and a
bridge for Eagles), organizing campfires, building fires and preparing meals in the woods with
bulk ingredients (requiring division of labor in preparing hamburger, cutting chunks of meat,
mixing Kool Aid, cutting watermelon, etc.) were problems common to both groups.
On the other hand, some conditions were confined only to one group, because of their
particular location in the outdoor setting, special interests, etc. For example, the Eagles' cabin
was closer to the water than the Rattlers', and a problem arose in the Eagle group which was
not at all prominent for the Rattlers. On Day 3, the Eagles discussed the need for screens twice
during the day, and when the screening arrived an Day 6, joined to install them. Another
problem situation arising from the particular situation of the Eagles was where to swim. Three
spots were easily accessible (boat dock, Rattlesnake Bay, Moccasin Creek), and the proposals,
counter-proposals, persuasions and decisions on this topic were frequent (e. g., 2 occasions on
Day 3, one on Day 4, one on Day 6). The Rattlers swam at their hideout and there was no
problem of deciding where. A number of interdependent activities embodying common goals
arose which were peculiar to the Rattlers. One was the dam-climbing game which Mills
organized after 2 group members climbed it. The idea of this game was to achieve the top
without back-sliding and to keep in the same position each time. Like most games with rules, it
required reciprocal regulation along with exhibition of skill by individuals. A spontaneous activity
peculiar to the Rattlers which met experimental conditions even better was their use of
swimmer escorts and a protective circle to encourage a new swimmer to dive, and thence to
encourage non-swimmers and non-divers. This activity involved almost the entire group.
As a result of repeated interaction in a variety of activities, all of which embodied goals common
to the individuals and required interdependent efforts, status structures were stabilized by the
end of Stage 1. One evidence of this is that the daily status ratings by participant observers of
their respective groups correspond closely for the last several days. Below is a list of status
ratings by participant observers of the Rattler and Eagle groups on the last 2 days of Stage 1:

*Since Eagles came to camp 1 day later Day 7 was last day for them. (Names in brackets left
camp because of homesickness.)
On the last day of Stage 1, the participant observer of each group and another observer familiar
with the group in question made independent status ratings of the respective groups. The rank
order correlation between independent status ratings for 2 observers for each group is given in
Table 1.
At this point sociometric choices would have provided a [p. 87] further check on observational
evidence and ratings, as planned in the study design (Chapter 1). However, as noted earlier, it
was decided that repetition of sociometric procedures 3 times (after each stage) during such a
brief time might arouse the suspicions of subjects and invalidate the results. Therefore,
sociometric choices were obtained only in Stages 2 and 3.
This was the crucial point at which status relations of the developing in-groups were to be
tapped through judgmental indices obtained in relation to performance throwing handballs at a
target (See Chapter 2). Our previous research had shown that differential judgments of
performance on a task in an unstructured situation may serve as indices of the relative status of
the person whose performance is being judged. Attempts to carry out this unit at the end of
Stage 1 were met with disappointment owing to mechanical failure of the apparatus, which did
not register the actual score attained. Since the actual scores are a critical part of the data, the
experiment could not be carried out without remedying the mechanism, which proved
impossible at the time. (The failure was due in part to loss of tension by brass and phosphor-
bronze spring contacts, but chiefly to a thin film of iron oxide which formed on bolt-base
contacts as a result of high local humidity at night.)
On the basis of observational data and observers' ratings, it was considered that the criterion
for formation of group structure under conditions of interdependent activity toward goals with
common appeal value to individual members was satisfied.
Before continuing to other hypotheses for Stage 1, certain characteristics of the group
structures at this time are worth considering briefly because of their implications for theory and
research in this area, particularly on leadership. First, the group structures at the end of Stage
1 were not static or rigid. Fluctuations as a result of changed conditions and status strivings of
members were noted. On the other hand, these groups had lived and interacted together for an
entire week. They were doubtless stabilized to a considerably greater extent than many
experimental groups currently employed in small group and leadership research, which meet
periodically for much shorter periods of time and are usually set to tasks provided entirely by
the experimenter. It is possible, therefore, that our findings may be revealing in relation to
current controversies over group [p. 88] structure and the stability of leadership.
It is frequently contended that a hierarchy is not necessarily a general feature of group
structure and that multiple leadership frequently exists. This contention is based on the finding
that in "leaderless group" situations, leadership not infrequently changes hands from situation
to situation with the task, and that differentiation of other functions varies similarly. This finding
is repeatedly verified and is perfectly reasonable for such situations.
However, in the present study, which is designed as a prototype of life-like interaction in varied
situations all embodying common and valued goals, differentiation of functions within the group
took place over a period of time along hierarchical lines. This is indeed characteristic of lasting
groups whose members are highly motivated in the direction of group goals in everyday life.
The evidence for this hierarchy is not so much in manner of treating others within the group, as
in the extent to which initiative (suggestions, directions, etc.) in group activities is taken, and
whether or not such initiative is effective (viz., whether suggestions are accepted, plans tried
out, etc.). The ratings by participant observers in the present study were based mainly on the
extent to which each member took initiative (e. g., made suggestions or plans, gave directions)
and the relative effectiveness of these efforts.
Here, concrete examples may make the theoretical point clear. Many members in each
experimental group showed "leadership" in the special sense of initiating activities, making
suggestions, carrying-through tasks in various situations. However, by the end of Stage 1, each
group had and recognized that they had a "leader" (Mills in the Rattlers and Craig in the
Eagles). At this time initiative by others in the form of suggestions, plans, action was effective
when the leader approved it. When he did not the matter was ordinarily dropped, perhaps after
an argument. In both groups, the leaders effectively chose baseball captains by backing their
choice. Baseball was extremely important to these boys, but the baseball captain in Stage 1
was in neither case the group leader. In both groups the leader told the baseball captain which
position he (the leader) would play. [p. 89] Two examples were given in the running accounts
and there are many more instances of the leader taking liberties in baseball and not being
censured by the captain. (The exception to this was when Craig of the Eagles wanted to
umpire; the entire group - not just Mason the captain - told him he could not be, that staff
should umpire and he accepted this. In short, he was exceeding even the bounds of his
leadership, and he accepted the group's judgment. Note Craig's behavior in intergroup
competition in Stage 2 and its effects on his position.) On occasion a high status Rattler
(Brown) was observed to hold the ball so that Mills could get in safe. Craig told Mason, the
Eagle captain, he couldn't play if he didn't have his shirt stenciled with the group insignia.
The findings in Stage 1 of this experiment do reveal initiative displayed by various group
members on different occasions. They do not reveal "multiple leadership" in the sense of shifts
in the control of group activities with shifts from one situation or task unit to the next, after group
structure was stabilized as a result of continuing interaction over a time span.
Hypothesis 1a, Stage 1
If a definite group structure develops, it will be reflected in a consistent pattern in
directions of communication. The specific pattern in directions of communication will
be as follows: The higher the status of a group member the greater the frequency of
suggestions (for group activities) addressed to him.
Because of the intensive and varied demands of both a scientific and practical nature placed on
the participant observers, the observational data do not contain precise quantitative evidence
needed to evaluate this hypothesis. Summaries representative of the scanty evidence available
are presented here as suggestive for future research.
Rattler group:
Day 1: Brown was elected to work out a buddy system. Suggestions were made to
him.
Day 2: In discussion on work at hideout suggestions were made directly to Brown
by Mills, Swift, Simpson [p. 90] and others.
Day 3: Morning - Brown clearly ran the boat project with queries and suggestions
coming to him and decisions made by him.
Afternoon - During work on diving board, lower level members stopped
communicating with Brown. Mills organized them. Brown's slip from leadership was
noted.
Day 6: Pine cone battle started by Mills, involving all boys, and centering
communication to Mills. Observer noted frequent instances from Day 1 in which
Mills had made himself the enter of attention and in which he had circulated among
the group communicating with both high and low status members.
Afternoon - During the discussion of how to spend the Treasure Hunt reward ($10),
suggestions and remarks were counted. Results:
To Mills - 16
To others - 1
At large 6
Suggestions during discussions of T-shirt and flag insignia were made to Mills, who
accepted some of them but largely determined what was to be done himself and got
group approval.
Day 8: At campfire, Mills organized skits. Suggestions and requests came to him
("Let me, A....!"). He included almost every boy at one time or another. He also
encouraged Brown and Simpson in their individual performances.
Eagle group:
Day 5: During the group Treasure Hunt, Craig found only one note, but he was
given 5 others to read to the group by those who found them. In discussing how [p.
91]
to spend reward, suggestions by middle and low status members were ignored.
Davis' suggestion (hardball equipment) was backed by Craig, who called for a vote,
declared it passed, wrote it down, told others to line up to sign it.
In deciding on 8 items for the camp canteen, Craig and Davis made most
suggestions. Other suggestions were directed toward these 2, but many were
ignored ignored and Craig put his or Davis' suggestions in their stead. Several items
were decided upon by these 2 without consulting the group. Craig accepted Myers'
formulations for several items, which made them more general.
The above evidence, which is presented as suggestive, is in line with the hypothesis.
Hypothesis 2, Stage 1
When individuals interact under conditions stated in hypothesis 1, concomitant with
the formation of group structure, norms regulating their behavior in relations to one
another and in practices and activities commonly engaged in will be standardized.
As the in-group structures of the Rattlers and Eagles became delineated, members formed
attitudes toward objects and places of functional importance to them, appropriating these
objects as "ours."
Rattlers:
On Day 2, the group explored upstream where they "found" their
swimming hole and hideout. By Day 6, this was "our Upper Camp" and
the cabin was "home." When paper cups were found at the hideout,
resentment was strong against supposed intruders.
The ball diamond was discovered on Day 5 with negative reaction. Play
and improvements on Day 6 contributed to appropriation. On Day 8
(after hearing Eagles on it), the ball diamond was called "ours." [p. 92]
The Stone Corral (behind Robbers Cave) was appropriated as "ours"
and used for campfires.
Eagles:
Moccasin Creek was used for swimming on Day 2 and boys decided to
swim there in future, leaving equipment there. They did so in spite of
seeing snakes there, returning to it in preference to the (beautiful)
reservoir. Signs naming Moccasin Creek and Copperhead Hill (across
the stream) were put up on Day 4. Pictures of this area were exclusive
subject of arts and crafts period, Day 5.
Campfire circle was re-named "0. U. Camp" on the first night, and a sign
put up labeling it.
Attitudes toward other members of the in-group and persons important in the group's
functioning were stabilized. This is particularly evident in the case of individuals whose behavior
was for some reason prominent within the group. Some of these standardizations were
temporary, while others were more enduring. An example of the latter is the nickname "Red" for
Brown (Rattlers) which typified his coloring and probably his size and "toughness. " Among the
Eagles, Myers, as noted briefly in the summary of interaction, engaged in considerable "show-
off" behavior during the first days. At one time while preparing a fire, he spoke of himself with
approval as "Smart Bob." Several boys echoed: "Dumb Bob! Crazy-mixed up Bob!" Such terms
were used on occasion throughout this stage, although Myers began to make definite efforts to
be accepted. A more enduring nickname for Myers was "Nudie, " given when he started
swimming in the nude. At his suggestion the group occasionally referred to themselves with
hilarity as RCNCI (Robbers Cave Nudist Colony, Inc.). Other temporary nicknames in the Eagle
group were "Marilyn Monroe" or just "Marilyn" for a boy who gave a burlesque dance one night;
"Screwball, senior" and "Screwball, junior" for staff members.
Norms were standardized in both groups in relation to experiences and behavior which became
important to the group. The "tough" norm among Rattlers was a notable example. At various
times, Mills, Martin, Simpson and Harrison all carried [p. 93] on the rather strenuous activities
with injuries (all of minor nature). The staff had to remember to check Martin's bruised knee and
wrist because he never mentioned them. Harrison did not cry when he injured his hand, but did
cry later when he found out that it would keep him from the catcher's position, and members
sympathized with him. Swift did not conform to this tough norm, and was completely ignored
when he cried. Along with the "tough" norm went a definite approval of cursing. "Toughness"
and cursing are both norms of conduct among groups in the larger social setting; they were not
original to the Rattlers. However, these norms were not standardized among the Eagles. On the
contrary, cursing was definitely discouraged in the Eagle group (see also Stage 2), and crying
at injuries was indulged in even by Craig, the leader.
In the Eagle group, Davis and Boyd were ridiculed for about the last 3 days for being homesick.
A definite norm against being homesick was standardized, in relation to which these two were
seen as deviant. Mason, who had on occasion talked longingly of home, showed no signs of
wanting to go home in Stage 1 after the norm became established. Swimming in the nude was
another norm which was stabilized in the Eagle group. This practice was not taken up by the
Rattlers.
In both groups, methods of rotation or taking turns were standardized for saying grace at
meals. These activities were initially regulated verbally by high status members, but came in
time to be self-regulating. In the Rattler group, Brown passed the duty around for 2 days; then it
was rotated among low status members. When Mills attained a stable position as leader, he
designated the person to say grace. From the 7th day, the order of saying grace was pre-
determined by the group and followed without prompting.
During the early part of Stage 1 in the Eagle group, Davis usually told one of the boys to give
thanks after he had figured out which one had not said grace as many times as the others.
When he lost track, he asked each of the boys to state how many times he had said it. When
Davis became homesick, Craig took over the function for a short while, but soon quit trying to
keep track of whose turn was next. Thereafter, thanks was done on a volunteer basis, the end
result being the same: the boys rotated the duty among themselves.
[p. 94] Spontaneous games were standardized (probably not original) in both groups: waterball
among Eagles with a special "hot potato" rule; dam climbing with definite rules governing order
and maintenance of positions among the Rattlers, as well as a paper airplane game.
One group product which clearly signifies in-group delineation is naming the group. The name
chosen by the Rattlers is hardly coincidental in view of the not infrequent sights and encounters
with rattlesnakes, notably during their overnight campout. Significantly enough, the only other
suggestion in the Eagle group for a name was "rattlesnake biters." Eagles adopted their name
after becoming concerned about the other group in camp. (Myers asked if the other group had
a name.)
Both groups had favored songs, the Eagles referring to one consistently as "our song."
In both groups during Stage 1, deviation from norms or decisions by the group led to being
"called down" or ignored. Myers was ignored by the Eagles when he refused to be "out" in
baseball. When Swift did not live up to the "tough" norm, other Rattlers ignored him. Members
were chastised verbally by others for not doing their share of work in both groups.
Reactions to the other group: When the in-group began to be clearly delineated, there was a
tendency to consider all others as out-group. The Rattlers' reactions to paper cups at Upper
Camp, which they didn't remember leaving, will be recalled. The Rattlers didn't know another
group existed in camp until they heard the Eagles on the ball diamond; but from that time on
the out-group figured prominently in their lives. Hill (Rattler) said "They better not be in our
swimming hole." The next day Simpson heard tourists on the trail just outside of camp premises
and was convinced that "those guys" were down at "our diamond" again. When the presence of
another group was definitely announced, the Rattlers immediately wanted to challenge them,
and to be the first to challenge. Performance in all activities which might now become
competitive (tent pitching, baseball, etc.) was entered into with more zest and also with more
efficiency. Since the efforts to help "all of us" to swim occurred after this, it is possible that even
this strictly in-group activity was influenced [p. 95] by the presence of an out-group and a desire
to excel it in all ways.
The Eagles were informed that another group was in camp three days before the end of Stage
1, but they made no comments on the fact. On the following day, Wilson said he had seen a
boy across the grounds, but no one remarked on this. When the Eagles were playing on the
ball diamond and heard the Rattlers, Wilson referred to those "nigger campers." Cutler asked to
play them. Craig at that time issued a challenge to the Rattlers through staff. The very fact that
the Eagles decided to elect a ball captain was in anticipation of playing the Rattlers. The need
for a name did not occur to the Eagles until they contemplated playing in competition.
In summary, by the end of Stage 1, as a result of repeated interaction in situations embodying
goals common to all individuals and requiring interdependent activity for their attainment, clear-
cut in-group structures and by-products (norms) of the in-teraction process were stabilized.
Discovery of another group of campers brought heightened awareness of "us" and "ours" as
contrasted with "outsiders" and "intruders," an intense desire to compete with the other group in
team games, and enthusiastic preparation to do so. These developments set the scene for
Stage 2.

[p. 96] CHAPTER 5
Intergroup Relations: Production of Negative Attitudes Toward the Out-group
During Stage 1, the experimental conditions which were introduced at times when they had
appeal value to the subjects, and the interaction processes that arose produced two definite in-
group formations. In time, each group had a definite structure in terms of statuses for individual
members. Each group had its name, symbols of identification, places and facilities appropriated
as "ours." Each group had its preferred songs, practices and peculiar norms. In short, each
group had its particular set of group products. As noted, the groups followed somewhat
different rates in developing an organization and emphasized different features in their group
products.
Having produced two in-groups independently of each other through control of conditions, we
could proceed to the study of relations between the groups through bringing them into
functional contact under specified conditions. For reasons mentioned in Chapter 2, the first task
was production of intergroup friction in order to proceed to the main phase of this study, viz.,
reduction of intergroup friction.
The distinguishing characteristic of Stage 2 is the interaction of the two groups under controlled
conditions which are perceived by members of the respective groups as competitive and
reciprocally frustrating. In other words, the aim of this stage was to control conditions so that
each group would see the other as a competitor and likewise as a source of frustration. In
planning this stage, we had invaluable experience from our 1953 attempt in which, at an
important point during this friction phase, the source of friction was attributed to the camp
administration. The 1953 study had to be terminated at this point for this reason.
Stage 2: Experimental Conditions and Behavioral Events
The two in-groups themselves set the stage for the friction phase of intergroup relations. During
the last days of Stage 1, both the Rattlers and Eagles became insistent in their desire to [p. 97]
challenge the other group of boys to play competitive games, especially baseball. The design of
the experiment required a clear-cut stabilization of a definite structure within each group. While
the staff ascertained this, the Rattlers and Eagles became impatient in their desire to engage in
competitive games. When the staff members informed each group that that there was another
group in the camp area, the challenge was unanimous and enthusiastic. Delaying Stage 2
became increasingly difficult. When the Rattlers heard the other group playing on "their" ball
field, they made remarks expressing the feeling that they considered others playing there as
intrusion. Even without coming into physical contact with "those boys at the other end of the
camp," the Rattlers had built up a highly competitive mood in relation to them.
The plan for a tournament of contests was made to appear to the subjects as based on their
own manifest desire. The tournament plan, therefore, was not formally announced before the
participant observers carried on a number of informal talks with their respective groups
explaining that the staff had to make the necessary arrangements. The formal announcement
and exhibit of the trophy, prizes and medals for the tournament were postponed until the
second day of Stage 2. The first day was devoted to informal talk about the tournament by staff
and members of each group, items that were to be included in it, and about prizes. There was
no physical or visual contact between groups on this day.
The Rattlers' reaction to the informal announcement was full confidence in their victory. They
spent the day talking about the contests and making improvements on the ball field, which they
appropriated as their own to such an extent that they spoke of putting a "Keep Off" sign there.
They ended by putting their Rattler flag on the backstop. At this time, several Rattlers made
threatening remarks about what they would do if anybody
bothered their flag.
The Eagles did not exhibit as much enthusiasm as the Rattlers when they first learned about
the tournament in this informal way, even though there were a few "Oh, boy!" expressions.
They were interested to learn if the other boys were practicing. Wilson and Cutler said, "We'll
beat 'em," and several other boys joined in the discussion.
[p. 98] Mason (best athlete in the Eagles) and Simpson (Rattler) had previously been chosen
baseball captains in their respective groups. Both boys had been elected captains as
consequence of their nomination by the acknowledged leaders of their respective groups (Craig
and Mills). From the time the tournament began, Mason was to come to the foreground as
leader in the Eagle group in athletic as well as other matters, until the end of Stage 2.
Both groups spent most of the day practicing and preparing for coming events. Craig (Eagle
leader) attached the Eagle flag to a pole, and another Eagle said, "Our flag shall never touch
the ground." At one point during the day, Myers (E) (Note 1) expressed the opinion that "maybe
we could make friends with those guys and then somebody would not get mad and have any
grudges." On the following day, just before the baseball game started, when the two groups
actually set eyes on each other and came into physical contact for the first time, derogatory
name-calling began when this same Myers called one of the Rattlers "Dirty Shirt."
On the second day of Stage 2, the two groups had breakfast at different times. The members of
both groups were fascinated at the sight of the tournament exhibit. When it was their turn to
come to breakfast, each group saw the exhibit, consisting of a trophy, medals, and 11 four-
bladed knives. After each group had breakfast the staff made the formal announcement of the
tournament to each separately. The contest activities included in the tournament and the score
for each were specified. It was explained that the group making the highest cumulative score in
the series of contests would win the trophy, and the individual members of the winning group
would receive the prizes (a knife and medal).
The prizes had great appeal to the boys. One group had included knives as one of the few
items selected for the canteen list. (The inclusion of knives on the canteen list was to be
brought up again by the losers after the tournament was over. The winners were to guard their
knives scrupulously. The trophy was so valued by the winners that they kissed it after they took
possession and hid it for safety in a different cabin against a possible seizure by the losers.)
The series of events cited in the formal announcement had to be modified when the tournament
started, with the consent of [p. 99] both sides, partly because some events were not very
appealing to the subjects and partly because some were decided to be somewhat hazardous.
what hazardous. The actual events were completed in 7 days and included the following items:
A. Events whose outcomes could be checked by contestants:
1. First baseball game (Day 2)*
2. First tug-of-war (Day 2)*
3. Second baseball game (Day 3)
4. Second tug-of-war (Day 3)
5. Touch football game (Day 4)
6. First tent pitching (Day 4)*
7. Third baseball game (Day 4)
8. Third tug-of-war (Day 5)
9. Second tent pitching (Day 5)
10. Third tent pitching (Day 5)
*Victors had to win 2 contests out of 3 for the marked activities.
B. Events judged by staff members separately for the two groups:
1. First cabin inspection (Day 3)
2. Second cabin inspection (Day 4)
3. Third cabin inspection (Day 5)
4. Skits and songs (Day 3)
5. Treasure hunt (Day 5)
The items under category B were included to enable the experimenters to juggle points in such
a way that until the final events, both groups would be highly motivated with the hope of
winning the prizes. This juggling had to be done in the present study in favor of the Eagles, who
during the first day of actual competitive encounters (Stage 2, Day 2) lost both the first baseball
game and the first tug-of-war, the first event with a very small margin and the second in a
disorganized way.
[Classics Editor's note: Clck on any of the thumbnails below to see larger versions of the
photographs.]
Up to the last day, with the procedure of equalizing scores through the category B events, the
scores were fairly close together. The score values were indicated by rising thermometers on
the official score chart. The increase in the readings were made with considerable flourish at
meals when all boys were [p. 100] present (both groups). This neck-to-neck race in contests
continued until the last day of the tournament. The outcome of the tournament hinged on the
last event on the afternoon of Day 5 (Stage 2). This last event was the treasure hunt, which,
being conducted in the respective camp areas of each group, could be manipulated by the
experimenters in a way to insure the transition of two intact group structures to Stage 3, which
is the crucial stage of the study. In view of the fact that 2 boys from the Eagle group had been
sent home because of homesickness at the end of Stage 1 (see Chapter 4), leaving only 9
boys in that group, there was some danger of disorganization of the Eagles in case of their
defeat. More specifically, there might have been a revival of Mason's desire to go home. He
had been somewhat affected in this direction during Stage 1, probably through his contact with
the two boys who left the group. The fact that we could proceed two days after the end of the
tournament to Stage 3 indicated that the decision to tip the scales in favor of the Eagles was
sound.
Right after the treasure hunt, the two groups were brought together, each on one side of the
exhibit of prizes, and results were announced. The scores received by each group for every
event were specified, making the outcome hinge on the treasure hunt. The tournament was
declared to have been won by the Eagles through their completion of the treasure hunt in 8
minutes 38 seconds versus 10 minutes 15 seconds for the Rattlers. The Eagles were jubilant at
their victory, jumping up and down, hugging each other, making sure in loud tones that
everyone present was aware of their victory. On the other hand, the Rattlers were glum,
dejected, and remained silently seated on the ground.
The series of contests was the main focus of attention for both groups, manifested in actual
physical encounters and practice sessions in preparation for them, in group discussion, in self-
justifying and self-glorifying words used in relation to themselves, and invectives and
derogatory terms hurled at the out-group in actual encounters and in reference to the out-group
in the privacy of the in-group circle. Various contests had differential effects in producing the
above attitudinal and behavioral consequences. At least for these 11-year-old boys, the
activities which were not too prolonged and which involved direct physical contact were most
effective, with the tug-of-war heading the [p. 101] list. The build-up of negative attitudes was
cumulative with rapid spurts at times, as determined by the nature of the encounter. Even
though the boys hurled invectives starting with the first contest of the tournament, the norms
internalized from the larger social setting concerning "good sportsmanship" were clearly evident
for the first two days, as revealed through the custom of giving three cheers for the losers.
After the second day of the tournament, the "good sportsmanship" stated in specific words
during the initial period and exhibited after the first contests in this series (especially by the
Eagles) gave away, as event followed event, to increased name-calling, hurling invectives, and
derogation of the out-group to the point that the groups became more and more reluctant to
have anything to do with one another. This attitude of not having anything to do with each other
was intensified owing to the impact of events taking place after the tournament was over, as we
shall see presently.
The first physical encounter of the two groups, their immediate "sizing up" of each other, the
explicit expressions of their rapidly developing attitudes toward each other may have significant
implications for the systematic study of the rise of rather sharp an in-group and out-group
delineation and rapid crystallization of attitudes toward an out-group when the functional
relation involved is one of rivalry. Therefore, a description of this very first contact between the
two in-groups, which were formed independently of each other, follows:
The Rattlers were first at the ballfield (which they considered "ours") as befits the "home team."
The Eagles approached with their flag on a pole singing the menacing notes of the "Dragnet"
theme (See Figure). For a time the two groups looked each other over. Than [sic] an Eagle
used a derogatory word, a catcall from a Rattler answered him, and the razzing was on. Before
the game started, Mason gave a little lecture to the Eagles on not getting rattled. As the game
got underway, the Rattlers sang "The first Eagle hit the deck, parley-voo. . . The second Eagle
hit the deck, parley-voo. . ., etc. " Eagles called back at them: "Our pitcher is better than yours;"
"Our catcher is better than yours. " As the game progressed the Rattlers referred to Wilson (E)
as Fatty, Tubby, "Little Black Sambo." Myers, the Eagle of such good-will prior to the game,
was especially active in calling out at the Rattlers, though Craig tried to hush him with [p. 102]
words about sportsmanship.
Craig's downfall from leadership of the Eagles started during this game. He wanted to pitch
when Mason became tired, but Mason put in Wilson, saying later that Craig just wasn't good
enough. (In spite of this, Craig rubbed Mason's arm after the game.)
As the game continued, the Rattlers called, "You're not Eagles, you're pigeons!" When the
game ended with a Rattler victory, the Rattlers put on a display of "good sportsmanship" for the
losers. In the Eagle group, Mason threatened to beat up some Eagles if they didn't try harder,
but praised Lane (low status) for his improved performance. Craig, who had not made a good
showing, carried a Rattler glove left at the field and dropped it in the water near the Eagle
cabin.
The two competing groups were together in the mess hall for the first time at lunch on Day 2,
after the baseball game. There was considerable name-calling, razzing back and forth, and
singing of derogatory songs by each group in turn. Before supper that evening, some Eagles
expressed a desire not to eat with the Rattlers.
In saying grace at these first meals together, the members of each group expressed their
desire for victory. Myers (E) asked that God help them win the tournament and that He keep
them together and not let anyone else get homesick and go home. Allen (R) prayed: "Dear
Lord, we thank Thee for the food and for the cooks that cooked it, and for the ball game we won
today." In the Eagle group, prayers were said for victory at night, and it became standard
practice for that group to huddle in prayer before games (see Figure). Mason (E) attributed their
victory in baseball on the following day to this practice.
Before continuing with the tournament events, note should be taken of the behavior of sideline
participants in the various contests. Because there were 11 Rattlers and only 9 Eagles, two of
the Rattlers could not participate in certain of the contests (e. g., baseball, tug-of-war, etc.).
These non-players were chosen by the group and were always low status members, unless
injuries dictated the choice. Since these members were not actually taking part in the
competition, their behavior under these [p. 103] circumstances is particularly significant.
At the first baseball game on the occasion of first contact between the groups, Everett (R), who
had been chosen as one non-player, was the loudest of the Rattlers in haranguing the Eagles,
cursing them roundly and making up a song about Eagles which was supposed to be very
insulting. Harrison, the other non-player (because of an injury), arrived after the exchange of
insults between groups had already started. Although he had not witnessed the events leading
to friction between the groups, and, in fact, before he had exchanged a single word with any
camper, he started yelling insults at the Eagles.
There were numerous other incidents of this nature at the other contests, which illustrate the
point that actual physical participation is not a necessary condition for involvement and
participation in some form by good group members.
The afternoon of the first day was spent by both groups in intensive preparation for other
events. The Rattlers had cabin clean-up, practiced for tug-of-war, and washed their shirts which
they had decided to wear at every game. Mason delivered a lecture to the Eagles on how to
win, and the group practiced at tug-of-war for 45 minutes. Mason had organized a cabin-
cleaning detail before lunch, insisting on full participation, although prior to the tournament he
himself had shown no interest at all in such chores. Later in the tournament, Mason was to urge
his group to practice other activities in which he personally had little interest, such as the skits.
When he felt they were not trying hard enough, his usual procedure was to declare he was
going home, even starting out the cabin door. This device was very effective since the Eagles
were aware of Mason's value as player and captain, and it therefore resulted in renewed efforts
on their part.
The first tug-of-war was held after supper on this first day of the tournament. Simpson (R) was
particularly vocal in calling taunts to the Eagles. When the referee called for captains, Mason
stepped forward for the Eagles, although he had been elected only as baseball captain, and
Simpson stepped forward for the Rattlers. The contest began and the Eagles pulled the first
Rattler over the line. At this point, the Rattlers began moving the Eagles and continued doing
so until all the Eagles were across the line. When [p. 104] Craig (E) saw the Eagles were
losing, he walked away from the rope. The winning Rattlers cheered, jumped, and slapped
each other on the back, then gave three cheers for the Eagles (Mills noting, "that shows we are
good sports!"). They passed by the dejected Eagles with much yelling and razzing, particularly
from Everett who had not even taken part in the tug-of-war. Victory was on every Rattler tongue
that night, and the next morning the story of how Brown, their anchor man, had shouted "Yawl
come !" and they "just came", was repeated with great appreciation.
After this defeat the downhearted Eagles stood around discussing how big the Rattlers were.
Mason was crying, saying the Rattlers must be at least 8th graders, that he was going home,
that he would fight a Rattler the next time they met. (Since the Eagles had lost one of their
large boys through homesickness, and the Rattlers did have the largest boy in camp, there was
some basis for the Rattlers looking big to the Eagles.) Craig, who was chastised for leaving the
rope, said they were beaten already. Myers, Clark and McGraw took an optimistic view of the
situation, calling for teamwork and planned tactics. (The next day, as we shall see, the Eagles
actually did work out tactics before the tug-of-war which proved highly effective. See below)
Finally someone suggested the Eagles go back to their cabin. Lane (low status) started off first
and noticed the Rattlers' flag on the ballfield backstop. He yelled that they could take it down.
The Eagles all ran for the backstop, Craig trying to knock down the flag and then climbing up to
take it down. Mason grabbed it and tried, with the help of others, to tear it up. Someone
suggested: "Let's burn it." So Mason, Craig, and McGraw (who found matches) set the flag on
fire. Mason held it while it burned, then they decided to hang the scorched remnant back up.
Craig did so, and the boys sang "Taps." Mason said, "You can tell those guys I did it if they say
anything. I'll fight 'em!"
As they walked to their cabin, the Eagles spoke hopefully of how they would beat the Rattlers at
baseball the next day. Everyone told how they contributed to the contest, comparing rope burns
and aching muscles. As they went to bed, Mason found some hope for victories over the
Rattlers.
This flag-burning episode started a chain of events which [p. 105] made it unnecessary for the
experimenters to introduce special situations of mutual frustration for the two groups. The only
manipulation necessary to insure that the actions of one group were frustrating to the other was
careful timing of arrivals and departures of the groups on certain occasions. For this reason, it
was arranged that the Rattlers would complete breakfast and proceed to the athletic field
before the Eagles on the next morning, in order that the Rattlers would discover the damage
inflicted to their flag.
At breakfast the next morning the Eagles were relatively quiet, not being elated over their
progress thus far and perhaps wondering how the Rattlers would act when they found their flag.
Later the Rattlers agreed that the Eagles had looked happy at breakfast, but this judgment was
made only after they had found their flag.
As arranged, the Rattlers finished breakfast first and went to the ballfield. When they arrived
and discovered their burnt flag, their reaction was noisy and resentful. All sorts of suggestions
for retaliation were made in a disorganized fashion. Mills climbed the backstop to bring down
the burnt remnant, leaving a portion there for "evidence" at the suggestion of Barton and
Harrison. Simpson, the baseball captain, suggested that he ask the Eagles if they did it. The
Rattlers then made a plan of action to follow when the Eagles arrived. Simpson was to go and
ask the Eagles if they burned the flag. If the Eagles said that they did (and there was little doubt
in the Rattlers' minds that this would be the reply), Simpson was to start fighting and others
were to come to his help. Martin (a mild boy who had earlier espoused sportsmanship)
volunteered to grab the Eagles' flag and burn it. When the Eagles arrived, this plan was put in
effect. Simpson went to the Eagles and asked if they burned the flag, which they admitted. The
Rattlers followed up Simpson, calling invectives; Martin worked his way close to the Eagle flag,
grabbed it and ran down the road with some other Rattlers and with Mason (E) in hot pursuit.
In the meantime, on the field, the Eagles ran for the Rattlers' second flag which they had left on
the field. The remaining Rattlers tried to get it, but the Eagles tore it up. Swift (R) grabbed Craig
and held him in a wrestling hold, asking which Eagle had burned the flag. Craig said they all
had. Simpson (R) [p. 106] had gotten Cutler (E) down in a fist fight, and the physical encounters
had to be stopped.
The Rattlers who burned the Eagle flag returned with Mason (E), who was crying mad. He
yelled for someone "my size" to whip and Mills, the Rattler leader, said: "Here I am!" Staff
prevented further fighting and started the game over the Rattlers' violent objections to the
Eagles being "home team" that day, since the diamond was "ours" and "we built everything but
the backstop." The game finally got underway, with continued razzing and name-calling from
both sides.
From the point of view of leadership (see Chapter 4), it is very interesting to note that the
Eagles noticed the fact that although Simpson was the baseball captain for the Rattlers, Mills
was in fact the leader of the group. Myers (E) yelled, "One guy calling all the time-outs - Mills!"
Then he asked a Rattler if Mills was their captain, but the Rattler replied "No, he's at first base
(Simpson)."
A jubilant group of Eagles won the game. There was cheering for the losers again and Wilson
and Myers said "Nice game" to the Rattlers. Everett (R), who had been extremely noisy in
calling names at the Eagles from the beginning, said, "I think they are trying to be friendly, " but
none of the dejected, tired Rattlers who had played even bothered to reply.
As the Eagles walked down the road, they discussed the reasons for their victory. Mason
attributed it to their prayers. Myers, agreeing heartily, said the Rattlers lost because they used
cuss-words all the time. Then he shouted, "Hey, you guys, let's not do any more cussing, and
I'm serious, too. " All the boys agreed on this line of reasoning. Mason concluded that since the
Rattlers were such poor sports and such "bad cussers," the Eagles should not even talk to
them anymore.
The immediate effect of losing the game on the Rattlers was internal friction and mutual
recriminations among in-group members. This sort of immediate reaction to loss was observed
for both groups on some occasions in this study. In this case, Brown (R) criticized Newman
(pitcher) and Simpson (captain), who in turn retaliated and were supported by Allen and Barton
(both low status). Brown said he was going to write to go home. [p. 107] Later, Allen (a non-
player in this event) was criticized by Simpson for not giving enough support from the bench.
Allen, in turn, criticized Martin, who was supported vehemently by several others. Mills, the
Rattler leader, saved the day by making a joke out of the whole verbal skirmish, and Brown and
Alien both tore up letters asking to go home amid general rejoicing.
The second tug-of-war was notable both because the Eagles had planned a strategy which
caught the confident Rattlers off balance, and because it revealed in a striking way the
differential experience of two contending groups, one on the verge of victory and one on the
verge of defeat. This contrast between the experience of the two groups during this tug-of-war
was so striking that it was followed up by observers with questions the next day. The results of
this questioning are reported separately later in this chapter at the end of this running account
of interaction in Stage 2.
The strategy adopted by the Eagles was, on pre-arranged signal, to sit down and dig in their
feet. The Rattlers tugged strenuously for about 7 minutes and were almost exhausted when
they finally sat down and dug in too (see Figures). The Eagles were slowly but surely pulling
the fatigued Rattlers across the line when, after 40 minutes of the contest, a time limit of 15
additional minutes was announced. Later the Eagles were to talk about how short the contest
seemed and the Rattlers how long it seemed. After the event, Mason (E) started to shake
hands with the Rattlers. The Rattlers told him to "shut up" and called him names. Good
sportsmanship was on the downgrade.
All afternoon Simpson (R) made suggestions that the Rattlers raid the Eagles' cabin. Now, as a
result of the tug-of-war, in which the Rattlers believed the Eagles had used decidedly unfair
tactics, the Rattlers' mood was definitely favorable to a raid. Mills, their leader, set the time for
10:30, after the event of skits which each group put on separately that night. Enthusiasm for a
raid was high, and the Rattlers decked themselves out for it in true commando style (darkening
faces, arms, etc.). The Eagles had gone to bed by this time, and all were asleep but Mason,
who jumped up to arouse others when the banging and noise began. Some of the Rattlers
entered the cabin to turn beds over and rip mosquito netting on the windows, while others stood
outside and challenged the Eagles to come out and fight. Some of [p. 108] the Eagles slept
through the raid but those who were awake sat on their beds as though stunned. After the
Rattlers left, Mason shouted to the Eagles that they were "yellow", especially Craig who had
pretended to be asleep. Mason said the Rattlers had tried to blind them with a light (in reality a
flashbulb from a staff camera). Most Eagles were aroused enough to want to retaliate that
night; but staff prevented this when it was mentioned that rocks would be used.
Back in the Rattlers' cabin, many wild tales of the raid were being repeated over and over. Mills
was considered especially heroic because he jumped in a window and secured comic books
and a pair of blue jeans which, much to the Rattlers' delight, turned out to be Mason's (E
leader). Mills painted these jeans the next day with orange paint, the legend "The Last of the
Eagles" being inscribed on each leg, and carried them like a flag (see Figure).
After breakfast on Day 4, which the Eagles ate first, the Eagles prepared for the retaliatory raid
which they had planned the previous night. After making sure that the Rattlers were in the mess
hall, they started off, armed with sticks and bats, and led by Cutler who had balked at
participating in a raid the previous night. The Eagles messed up the Rattlers' cabin, turning over
beds, scattering dirt and possessions, and then returned to their cabin where they entrenched
and prepared weapons (socks filled with rocks) for a possible return raid by the Rattlers.
The Rattlers were furious at the Eagles for the mess created in their cabin, but were stopped
from rushing to "get" the Eagles when their counselor suggested that the raid might have been
planned so that they would lose cabin inspection. The Rattlers returned to clean up, cursing the
Eagles to a man. Simpson (baseball captain) called them "communists," and this was echoed
by Everett (low status).
Rain delayed the start of the touch football game. The Eagles spent this time planning what
they would do if the Rattlers came to their cabin; the Rattlers went to work with a vengeance
making posters and "raiding flags." At the game itself, the Rattlers were exceedingly vocal and
abusive. Everett and Allen (R) repeatedly told the Eagle staff members to get off their side of
the field, to "shut up", and called them derogatory names. [p. 109] Mason's pants, now a flag,
were waved victoriously by the Rattlers; but the Eagles ignored all this as much as possible.
The high status Eagles were telling their group not to yell at the Rattlers or brag in front of them
as this was thought to bring bad luck. Occasionally Wilson (who had risen near the top) forgot
this admonition, and had to be reminded. Clark (middle status) was the most vocal Eagle, and
he was reprimanded several times.
After winning the touch football game (narrowly) and the tent pitching, the Rattlers were
convinced that they were "winners" not quitters. The Rattler victory in football was so narrow
that the Eagles did not feel too bad at losing; but they thought their tent was erected much
better (though more slowly) than the Rattlers. Craig (E) walked away immediately after this
contest, and one of the Eagles said, "He's quit on us again" (as he had in the first tug-of-war).
The Eagles' morale shot skyward later in the afternoon when they won their second baseball
victory. True to their determination to be "good sports," they carefully refrained from making
bragging remarks in the Rattlers' presence. Bragging was approved behavior within the
confines of the Eagle group, but by this time it was frowned upon in the presence of the out-
group.
In seeking to explain their loss, which put them behind one point in the tournament, the Rattlers
pointed out the weak plays various members had made, but reached general agreement that
their loss was due to the fact that their bats were larger and heavier than the Eagles'. Martin
expressed the current mood: "It was just like having those (prize) knives in our pockets before
we lost the game." Simpson and Everett talked much of a raid, but nothing came of it at the
time. The Eagles discussed the possibility of being raided by the Rattlers, and collected a
bucket of stones (just in case), even "scouting" the Rattler cabin.
At breakfast on the last day of the tournament, the Rattlers sang "The enemy's coming...." as
the Eagles approached. After the meal the Rattlers decided to post flags on "everything that's
ours," including "home", "the swimming hole", "our Upper Camp", "our baseball diamond", and
the Stone Corral. They drifted off with the idea of raiding the Eagles' cabin, but met staff
members and abandoned the attempt.
The Rattlers won the third tug-of-war easily, but lost the [p. 110] second tent-pitching contest to
the Eagles decisively. Before lunch, Mason (E) directed: "Take all (the food) you can get; let's
don't leave much for them (Rattlers)." However, lunch was a relatively quiet meal. The Eagles
were figuring out whether or not they had to win both afternoon events (tent-pitching and
treasure hunt) or just one. They got into a discussion of their standing in the tournament up to
that time and decided they would have to win both of the remaining contests to win the
tournament.
Talk of raids had been in the air in both groups all day. The Eagles had mentioned the
possibility and indulged in bravado talk, but no plans were made. Simpson was pushing the raid
idea in the Rattler group, and as the possibility of their winning the tournament faded during the
day, it became generally accepted. Mills (leader) stipulated that it should not be a night raid,
because the Eagles had told them they were cowards to raid at night while the Eagles had
come in broad daylight. Martin said he would raid if the Rattlers won, but not if they lost
because that would be bad sportsmanship. (This same Martin entered into the raid that same
day without question after the Rattlers lost. He was one of few boys actually engaging in a
physical clash with two Eagles, and had to be forcibly restrained from fighting.)
The Eagles won the third tent-pitching easily and also won the treasure hunt (through
experimenters' manipulation in plotting the routes). Their elation and the dejection of the
Rattlers was described earlier in this chapter. Mason (E) was so happy that he cried. After
entrusting the beloved trophy to staff for safe-keeping, the Eagles set off for their Moccasin
Creek, some boys jumping in with their clothing on to celebrate.
The Rattlers raided while the Eagles were gone, messing up beds, piling personal gear in the
middle of the cabin, setting loose boats at the dock, and absconding with the prize knives and
medals. When the Eagles found what had happened, they rushed to the Rattler cabin shouting
invectives. Mason (E) was in the lead, furious and ready to fight. Lane and Clark were right be-
hind him, and Wilson, Myers, and Cutler arrived within seconds. (Craig, Bryan and McGraw
returned to the Eagles' cabin.) The groups lined up, separated by an invisible line. Mason and
others shouted at the Rattlers. Mason refused to fight the big Rattlers (Brown and Swift), and
the smaller Rattlers refused to step out to fight him. At last, Mason turned rapidly on his heel [p.
111] and strode toward the Eagle cabin. The other Eagles started to retreat, but did so facing
the jeering Rattlers, thus walking backward the entire distance. Clark and Wilson were the last
to leave and closest to the pursuing Rattlers.
About ten feet from the Eagle cabin, Mason came back with McGraw yelling to Craig and Bryan
in the cabin: "Come on, you yellow bellies. Are you going to lay down and take this ?" At this,
Craig came out and the Eagles took a last ditch stand before their Mason, Clark, Wilson and
Lane were in the front line; McGraw and Myers (who was frightened) composed the second
echelon, and Craig stood in the rear. The Rattlers told the Eagles that if they would get down
on their bellies and crawl, they would return the prize knives and medals they had taken.
Mason (E) begged the Rattlers to take out their two big boys and fight, which the Rattlers
refused to do. Martin (R) got into a fist fight with Lane (low status E). Mills (R) was scuffling with
Clark (E). At this point, it was decided to stop the interaction altogether to avoid possible injury.
The Rattlers' staff started forcing their boys up the trail to their cabin, one by one. Hill was the
last Rattler to be pulled away, and he struggled to go back.
As the Rattlers were being herded up the trail, the Eagles came right behind them yelling that
the Rattlers were running away. Eagle staff got the boys back to the cabin, but Mason ran out
determined to "get" the Rattlers. He was returned shortly. Lights were brought to the cabin
(lanterns and flashlights had been taken during the raid), and the boys began to clean up the
mess. When the staff member who had the role of camp director arrived with some of the
stolen prizes, the Eagles brightened up and told him about the event (since he had not been
present). By the time they were through telling of their exploits, the Eagles had turned the
whole affair into a magnificent victory for themselves. They related that the Rattlers would not
take their two big men out of the fight, and how they had chased the Rattlers "over halfway
back to their cabin" (actually about 40 feet).
The end result of the series of competitive contests and reciprocally frustrating encounters
between the Eagles and Rattlers was that neither group wanted to have anything whatsoever to
do with the other under any circumstances. On previous days, the now familiar invectives and
names had been hurled back and forth ("stinkers, " "braggers, " "sissies, " and many
considerably [p. 112] worse), derogation of the out-group had been expressed in word and
deed (e. g., holding noses when in their vicinity). Now both groups objected even to eating in
the same mess hall at the same time.
Clearly negative attitudes and social distance in relation to the out-group were standardized in
both groups. These products of intergroup friction could have been tapped at that time through
judgments of performance and stereotype ratings. Nevertheless it was decided to delay these
crucial checks of the products of intergroup friction for one more day (a) to avoid the possibility
of obtaining merely momentary reactions to the out-group, and to insure that the attitudes
toward out-group had some stability, and (b) to secure further checks through a planned
encounter between the groups. Accordingly the day after the tournament ended (that is, the day
after the Rattlers raided the Eagles) was set aside as an interim period devoted entirely to in-
group activity with the exception of one planned contact between groups.
The Eagles were taken to Lake Carlton, a more civilized and comfortable place to swim and
picnic. They spent the day in self-contained and contented in-group activity, all pitching in to
make the swim and picnic a success. There was discussion of the Rattlers, what a "bunch of
cussers," "poor losers" and "bums" they were, and of the Eagles' glorious "victory" in the
previous night's raid (see above). Craig carried the Eagle flag, and the group stayed entirely
apart from other people on the beach. The only exchange with outsiders was when Lane
bumped into someone and said, "Excuse me."
The Rattlers spent most of the time at their hideout, swimming, playing, and working in a
congenial and happy manner with everyone included (Mills, the leader, making special efforts
to involve low status members in games). There were occasional references to the Eagles as
"sissies," "cowards," "little babies," etc. Upon returning to camp for supper, the Rattlers made it
clear that they did not want to eat with the Eagles, who as it happened were not there. Martin
and Hill asked if knives were on the canteen list. Mills said he didn't want the kind of knives the
Eagles had won, and others expressed interest in having knives, but not the kind the Eagles
had won.
The Eagles returned after supper. As planned for the "test [p. 113] situation" arranged by the
staff, the Rattlers were taken on a hike in the Eagle area, passing within about 20 to 30 yards of
the Eagles' cabin. Mason heard the Rattlers approaching and yelled, "Come on, you guys,
we're being raided!" After the boys had rushed toward the cabin, Mason stopped to listen.
Bryan and McGraw had by this time taken to the bushes to hide. In the meantime, the Rattlers,
with Mills, Brown, Simpson and Everett in the lead, decided to take a look at the Eagles'
hideout (Moccasin Creek). There they became quite engrossed in crossing the Eagles' rope
bridge, and although the Rattlers mentioned above spoke of cutting it before they left, this was
not done.
The Eagles were discussing the possibility that the Rattlers might do something to their
swimming hole, Wilson, Clark and Mason arguing that they should protect it. Wilson said he
thought they must be at O. U. Camp: "That's our camp and they'll try to tear down our sign."
The Rattlers returned by the Eagle cabin, yelling insults in loud voices. Mills (R) said: "They
were afraid to even look at us." The Eagles inspected their swimming place the next morning
and commented that there were more rocks in the water, which the Rattlers must have been
responsible for.
Thus, reaction in this test situation further confirmed the prior evidence of this friction phase of
intergroup relations which by this time had crystallized in negative attitudes toward the out-
group (stereotypes of out-group characteristics and considerable social distance in relation to
its members). These negative attitudes were maintained even after intergroup contact in
competitive and reciprocally frustrating situations ceased.
How Long the Tug-of-War Lasted
Viewpoints of groups on the verge of victory and defeat: Among the factors frequently reflected
in judgments of objects, persons, or events in Stage 2 were immediate and long-range trends in
intergroup relations, strenuous physical efforts, victory or defeat, etc. A striking contrast
between groups, as evidenced by differential effects along group lines, was seen in estimates
of the time consumed by the second tug-of-war. As noted above, reactions of the two groups to
this event were followed up by participant observers. Evidence for differential experience by the
members of the two rival groups was found, both [p. 114] when estimates were made
individually and when they were a matter of concensus [sic] within groups.
The Rattlers had won the first tug-of-war easily. When the groups met again the Eagles had
adopted a strategy of sitting down and digging in their feet. The Rattlers stood up and pulled
mightily for about 7 minutes (losing ground steadily) and were almost exhausted when they
finally sat down and dug in too. The Rattlers' fatigue gave the Eagles a decided advantage, and
they were gradually pulling their opponents across the line when, at the fortieth minute of the
contest, a time limit of 15 additional minutes was announced. The event ended in a tie through
a mighty effort of the Rattlers to keep their last man from crossing the line.
Later in the evening, at their own cabins, both groups talked about the event. Most of the
Eagles seemed to feel that the time had literally flown by, one of them saying, "That was the
shortest ten minutes in my life" (referring to the last 15 minutes of the contest). However,
remarks at the Rattler cabin revealed that they felt the event had lasted a "helluva long time."
Since these remarks indicated differential biases according to group membership the members
of both groups were asked individually by their participant observers on the morning following
the event, "How long did the tug-of-war last after both groups sat down and dug in?" The
objective time was 48 minutes. The estimates made are tabulated on the following page.
It is significant that the Eagles all gave their estimates in minutes and the Rattlers all gave
theirs in hours, even though the same question was asked both groups and all boys were
questioned individually. The members of the two competing groups used the same dimension
(elapsed time) in making estimates, but used different units - the shorter unit being used by
those on the verge of victory and the longer by those on the verge of defeat. Also, it was found
on further questioning that the Rattlers were unable to differentiate between the length of time
occupied by the whole event and the time after both groups sat down.
Note that the median judgment for the Eagles represents an 18 minute underestimation of
elapsed time; that of the Rattlers a 12 minute overestimation. The median judgment for Rattlers
[p. 115] was twice that of the Eagles, giving a 30 minute difference between groups. Although
there is no overlap in judgments of the members of the two groups, and the significance of the
results is obvious, they may be put in the more formal language of statistics. According to the
Mann-Whitney U test (1947) the probability of getting these estimates, so distributed between
groups, by chance is less than .001.
After polling the group members individually, each participant observer asked his group (at a
time when the group was all in one place) how long the event had lasted. After some
discussion the Eagles decided the estimate should be 45 minutes (the original estimate of the
group's leader). The Rattlers decided it was "over an hour." These estimates arrived at by
consensus still represent under- and overestimations of the objective time.

[p. 117] CHAPTER 6
Intergroup Relations: Assessment of In-Group Functioning and Negative Attitudes
Toward the Out-Group
In order to insure validity of findings and to increase their precision, the plan of this experiment
on intergroup relations specified that different methods of data collection would be used and the
results checked against each other (Chapter 2). On the other hand, it was noted that excessive
interruption of the interaction processes would result in destroying the main focus of study, viz.,
the flow of interaction within groups and between groups under varying conditions. Therefore, it
was necessary to exercise great restraint in introducing special measurement techniques and
experimental units to cross-check the observational data.
At the end of Stage 2, special methods were utilized to check observations related to the main
hypotheses for the friction phase of intergroup relations. In addition to sociometric techniques,
two experimental units were introduced to tap the subjects' attitudes toward their respective in-
groups and the out-group. The results of these units are presented in this chapter, along with
additional observational data pertaining to the various hypotheses for Stage 2. These results
are not intended to test any separate hypotheses, but to provide further evidence to be
evaluated in conjunction with the observational data.
Section A summarizes the effects of intergroup friction on in-group functioning, while the
following sections deal with end-products of intergroup friction and conflict, and their
assessment through judgmental reactions.
A
Intergroup Friction and In-Group Functioning
The study of in-group structure and functioning was not confined to the first stage of the
experiment, which was devoted to experimental formation of in-groups. Several of the
hypotheses for Stage 2 specifically concern the effects of intergroup relations (friction, in this
case) on in-group structure and functioning. Some [p. 118] consequential effects to the
respective in-groups were pointed out in the summary of interaction in the last chapter. Further
data will be summarized here. Throughout the experiment the effort was made whenever
possible to obtain data by as many methods as feasible without disrupting the ongoing
interaction. Checking results obtained by several methods (e. g., observational, sociometric,
ratings, judgments of the subjects) leads to confidence in the reliability and validity of the
conclusions reached. In considering the hypotheses and data concerning in-group relations in
Stage 2, it was necessary to rely heavily on observational data. The more precise techniques of
data collection (viz., stereotype ratings and laboratory type judgments) were used for testing
the validity of observational findings concerning the negative attitudes (see section B, this
chapter).
Because of space limitations, the observational data of this experiment were given in summary
form. The danger of selectivity in observation and in reporting observational data is not
surmounted by piling example on example. The illustrations chosen are representative of the
many available. The conclusions drawn from them are justified by available evidence. They are
intended to be suggestive for future research in which observational methods are
supplemented increasingly by other more precise techniques of data collection.
At the end of Stage 2, the Rattlers and Eagles were both clearly structured, closely knit in-
groups. This is revealed in observational data, observers' ratings, and in sociometric choices
obtained at this time from each member individually by the participant observer of his
respective group (who appeared as counselor to the subjects).
1. Testing in Terms of Sociometric Indices
The most general criterion on the sociometric questionnaire specified that friendship choices
should be made from the entire camp. Table 1 presents the resulting choices for this criterion
by members of the Rattler and Eagle groups. In spite of the fact that choices of out-group
members were forced somewhat by the manner in which this item was presented, the
proportion of choices of in-group members in both groups was approximately 93 per cent, [p.
119] and the differences between choices of in-group members and out-group members are
too large to be attributed to chance.

End Stage 2
Rattlers Eagles
Choices of f % f %
In-group members 73 93.6 62 92.5
Out-group members 5 6.4 5 7.5
Sociograms were constructed for the Rattlers and Eagles using total score on 4 criteria, as a
basis for placement of members (see accompanying sociograms). The score on each criterion
was the total of weighted choices, first choices receiving a weight of 4, second choices of 3,
third choices of 2, and those thereafter a weight of 1. The choice network was based on the
most general criterion (friendship); and rejections were obtained from an item included in the
interview, but not used as a criterion in computing total scores. The lines on the ordinates of the
sociograms represent Q1, Q2, and Q3 of these ranks in ascending order, the lowest line being
Q1.
[p. 120]
[p. 121]
Several discrepancies in ratings of group members based [p. 122] on the various criteria were
noted. Two of these criteria were concerned with friendship choices (one general, one more
specific), and two were concerned with initiative displayed by various members. It is significant
that the scores obtained for these two kinds of choice were widely disparate in several cases.
For example, Everett (R) ranked second on the friendship criteria but only ninth (out of 11) on
the initiative criteria. Craig (E) ranked seventh on the friendship criteria, but fourth on the
initiative criteria, as did Hill (R).
Since observers' ratings were made more on the basis of effective initiative than on popularity,
it is interesting to compare the status ratings of observers and ranks in total sociometric score
(4 criteria). As Table 2 indicates, the rank order correlation for these two rating measures is
significant and high. Observers undoubtedly gave greater weight to effective initiative than did
the combined sociometric scores. This greater weight given to effective initiative in observer
status ratings is revealed in cases of discrepancy between sociometric ranks and observer
ratings. For example, Brown (R) ranks fourth in sociometric score, but only eighth in observer's
ratings. In this case, the sociometric score as computed from choices does not reveal what the
observer knew, and what was also revealed during the sociometric interviews. Although Brown
received only one rejection from his group, he was mentioned by six members (more than any
other member) as the member who would stand in the way of what most of the group wanted to
do. To take another example, Bryan (E) ranked fourth in sociometric score and eighth in
observer's ratings. In this case, nothing in the sociometric interview revealed, or could reveal,
that Bryan was frightened of physical conflict and that during the closing days of Stage 2 he
withdrew from interaction altogether on several occasions (even hiding in the bushes). For this
reason, he was rated near the bottom of the group by the observer at this time (in terms of
effective initiative and influence in the group). On the other hand, the observer noted that since
many eagles were frightened of the Rattlers, they did not (excepting Mason, the leader) impose
sanctions because of Bryan's behavior. He participated effectively when physical contact with
the out-group was not in the picture. Nevertheless, Bryan had very little influence in the group
at the end of Stage 2. Such cases illustrate some difficulties in interpreting sociometric scores
based on choice, and point to serious problems of validity when sociometrics are used apart
from concrete observational material.

2. Testing in Terms of Observational Data
Three of the hypotheses for Stage 2 are concerned with in-group functioning. Data pertinent to
them is summarized below.
Hypothesis 2, Stage 2
The course of relations between two groups which are in a state of competition and
frustration will tend to produce an increase in in-group solidarity.
Observational data supports this hypothesis with the qualification that in several instances
defeat in a contest with the rival group brought temporarily increased internal friction in its
wake. This was noted in the Rattler group (Day 3) when they lost the second baseball game.
Disruptive tendencies within the group reached their peak when Brown and Allen wrote letters
that afternoon wanting to go home, thus threatening to leave the group. Solidarity was achieved
shortly afterward through the integrative leadership of Mills, whose joking about these events
led the boys to tear up their letters amid rejoicing by all members.
Similar signs of temporary disorganization followed the first tug-of-war, when the downhearted
Eagles stared loss of [p. 124] the tournament in the face. In this case, Myers, Clark, and
McGraw took the optimistic view that they had to plan tactics which would defeat the Rattlers.
After the group joined whole-heartedly in burning the Rattler flag, this view was accepted by the
leader as well, and considerable hope was seen for the next day.
A somewhat similar adaptation to defeat was made by the Rattlers at the end of the
tournament. In this important instance, group action in raiding the out-group was agreed upon
right after defeat, sanctioned and planned by the leader and lieutenants, and was executed
soon afterward. The aftermath was self-glorification with reference to the group and all its
members. The next morning, when Mills "roughed up" several group members, not one tried to
challenge his prerogatives, although any one of them could have whipped him easily. (It should
be noted here that the Rattler leader, Mills, was one of the smallest boys in size.) The rest of
that day was spent in highly congenial play in which Mills made special efforts to involve the low
status members and succeeded in effecting their active participation.
It should be emphasized that the temporary disruptive tendencies following defeat illustrated
above did not follow loss of every contest. Some defeats were accepted with remarkably little
concern or depression, either because the group in question (both Rattler and Eagle) had
decided prior to the event that they probably would not win it or because they felt they did not
have to win that particular event to win the tournament.
In instances where temporary disorganization did follow defeat (above), heightened solidarity
within the group was achieved through united cooperative action by the in-group against the
out-group, and this is in line with the above hypothesis. It should be noted and emphasized that
the aggressive actions toward the out-group which followed frustration of group efforts
experienced in common by in-group members were taken after they were sanctioned by the
leaders (Mills or Mason, the leaders of the Rattlers and Eagles respectively). These aggressive
actions were sometimes suggested by high status members (notably Simpson and Mills in the
Rattlers and Mason in the Eagles), and sometimes suggested by low status members (e. g.,
Everett in the Rattlers, and Lane in the Eagles). in no instance did the in-groups engage groups
in aggressive action toward the out-group if this had [p. 125] not been approved by the leaders
of the respective groups. Other evidence supporting this hypothesis as stated is the recurring
glorification of the in-group, recounting of feats and accomplishments of individual members,
support and approval given low status members, support given the leader, and intensified
claims on areas appropriated as belonging to the group.
The Eagles bragged to each other that they were "good sports" who did their best and who
prayed and didn't curse. Later they refrained from bragging in the presence of the out-group
since this was agreed to bring bad luck. The Rattlers were constantly telling each other, and all
within hearing distance, that they were brave, winners, not quitters, tough, and (naturally) good
sports.
After the contests and raids, stories were told over and over of the accomplishments of this
person and that person, blisters acquired in the tug-of-war were compared both in winning and
losing groups, and these tales of individual feats grew with each telling. (The dramatic reversal
by the Eagles of their role in the last raid was noted in the account of that event in Chapter 5).
Brown (R) revealed special gifts for recounting such episodes.
During Stage 2, Lane (low status E) was praised for his playing for the first time (by Mason).
Lane became more active in in-group affairs and said they must not swim so much in order to
save their strength for the tournament, even though he had earlier been a constant agitator to
go swimming at every possible moment. Approval was also given to low status Rattlers during
games. After the big raid in which Mason (E) had accused several Eagles of being "yellow-
bellied" and cowards, he "covered up" for them completely in telling staff of the events. No
mention was made of any defection; all Eagles were made to appear heroic.
The leaders (Mills and Mason) were supported by group opinion consistently, especially after
the first day or so when Mason was effectively extending his leadership in baseball (elected) to
all areas of group life. Mills was supported by the group even during games when he interfered
in decisions made by Simpson (baseball captain); and on one occasion he took Simpson out as
pitcher and put in another member in his place.
[p. 126] At the end of Stage 1, we mentioned the increased concern of the in-groups over
places appropriated as "theirs." Swift (R) even went so far as to object, when he saw fishermen
near their swimming hole, that they had no business taking "our fish." The Rattlers talked, near
the end of Stage 2, of putting signs on all of "their" places, including the ball diamond and
Stone Corral (which was a part of Robbers Cave). The Eagles were extremely concerned over
the fact that the Rattlers went to their hideout on the day after the big raid, and claimed they
could detect changes there which did not actually exist.
Hypothesis 3, Stage 2
Functional relations between groups which are of consequence to the groups in
question will tend to bring about changes in the pattern of relations within the in-
groups involved.
The most striking change in relationships within the in-groups as a consequence of the
particular functional relationship between them (rivalry and friction) was in the Eagle group. At
the end of Stage 1, Craig was acknowledged leader of the Eagles. Mason was elected captain
of the baseball team (only) with Craig nominating and backing him. Even after this, Craig
informed Mason that he could not play ball if he didn't have the Eagle insignia stencilled on his
T-shirt, and Mason submitted to this after some argument. From the first day of the tournament,
however, Mason began to extend his leadership to all group activities, while Craig lost ground
throughout Stage 2, being in the middle of the hierarchy by the end (fifth in rank). Some of the
incidents revealing this alteration in the Eagles' status structure are mentioned in the summary
of interaction presented in the last chapter.
Mason took the group goal of winning the tournament very seriously, giving talks on how to
keep from getting rattled, threatening to beat up everyone if they didn't try harder, lecturing on
how to win after the first loss in baseball. Although he had not shown interest in keeping the
cabin clean before the tournament, he organized cabin cleaning details, and struck Lane (low
status) for not helping pick up papers. He had praised Lane's playing in baseball earlier, and
the combined effect of Mason's attention was that Lane saw the necessity of reducing the
groups' swimming time to "save our strength" - for him a sacrificial act. [p. 127] When captains
for the tug-of-war were called, Mason stepped forward, although he had been elected only as
baseball captain, and there was no discussion on the point. When the Eagles burned the
Rattler flag, Lane first directed attention to it, but Mason took the initial action in trying to tear it
up.
Rather convincing evidence of Mason's leadership followed the second tug-of-war, which ended
in a tie. Estimates of the time consumed were first obtained individually for each boy, as
reported in the last chapter. Subsequently, the boys were asked in a group how long they
thought it lasted. Every single Eagle agreed with Mason' s estimate of 45 minutes, although
only one other boy had made previously an estimate that high individually.
Craig allowed leadership of the Eagles to slip through his fingers by submitting to Mason' a
decisions, perhaps in part because he recognized Mason's superiority as an athlete. (Mills in
the Rattler group was not as good a ball player as a few other members; nevertheless he kept
control of the group's progress even during baseball games. ) However, Craig fell as far as he
did in the status hierarchy because of his defection at several critical points during the
tournament. When the group was losing the first tug-of-war, Craig simply walked away from the
rope before the contest was over. Afterward he said the Eagles were already beaten in the
tournament, and tried to blame others for the tug-of-war loss. However, the Eagles blamed
Craig for the loss. When he walked away after the Eagles' loss in tent pitching, the comment
was: "He's quit us again. " Craig pretended to be asleep during the first Rattler raid, and kept in
the background during the second.
Another shift in the Eagle group which accompanied Mason's rise to the leadership position
was Wilson's increasing importance in the group. From a position in the middle of the group's
hierarchy (fifth) at the end of Stage 1, Wilson rose to become Mason's lieutenant through his
effective playing in sports, his concern with maintaining joint efforts to win the tournament, his
support of Mason's decisions. Mason chose Wilson as pitcher in preference to Craig during the
first baseball game, and the two figured together in most of the group efforts and activities
throughout Stage 2.
The most pronounced changes in the pattern of status relations in the Rattler group during
intergroup competition were in [p. 128] the cases of Allen and Brown. After the second baseball
game, which the Rattlers lost, Allen was accused of not contributing to the game. He, in turn,
accused Martin (higher status) of bragging; but Martin was supported by the other members in
the argument. The group members were ruthless in denouncing Allen who cried, wanted to go
home, and was talked out of it by Mills (leader). After this, Allen was ignored a good deal, was
not chosen to play on the team, and fell from a middle status level to the bottom. Mills'
friendship was his chief tie with the group.
Brown, the largest Rattler, slowly slipped downward in the status structure during Stage 2 until
just before the second raid on the Eagles. Because of a pronounced tendency to rough up the
smaller boys, Brown was subject to group sanctions and fell to the bottom level of the group.
During the raid his size so impressed the Eagles that he became something of a hero of that
event to the Rattlers, and had attentive audiences of smaller boys in recounting his feats.
Intergroup conflict was the medium by which Brown regained a position higher in the group at
the end of Stage 2, after having slipped to the bottom level.
Thus, changes in the pattern of relations within the in-groups occurred during Stage 2. These
changes are related to the altered contributions of the various members to group activities and
efforts as the in-group functioned in a competitive and mutually antagonistic relationship with
another group.
Hypothesis 4, Stage 2
Low status members will tend to exert greater efforts which will be revealed in more
intense forms of overt aggression and verbal expressions against the out-group as
a means of improving their status within the in-group.
The observations relevant to this hypothesis are inconclusive.
As noted in Chapter 2, this hypothesis was not intended to imply that high status members will
not initiate and actively participate in conflict with the out-group. In line with one of the major
tenets of Groups in Harmony and Tension (1953), its implication should be that intergroup
behavior of members consists mainly in participation in the trends of one's group in relation to
other groups. Since low status members would be highly motivated to [p. 129] improve their
status, it seemed a reasonable hypothesis that they might do so through active participation in
the trend of group antagonism and conflict toward the out-group. On the other hand, the
establishment and responsibility for such a trend in intergroup affairs rests heavily with the high
status members, as does responsibility for sanctioning and conducting affairs strictly within the
group. If an upper status member, even the leader, stands in the way of an unmistakable trend
in intergroup affairs, he is subject to loss of his standing in the group. This is precisely what
happened to Craig, the erstwhile Eagle leader, in the present study. He did not enter into the
tournament with sufficiently wholehearted identification with the group's efforts to win; he even
walked out on them at critical points when they were losing and "played possum" to avoid
conflict (raid) with the out-group.
In view of the necessity to clarify the intent and implications of this hypothesis, it should
probably be re-formulated along the following lines: Aggressive behavior and verbal expression
against the out-group in line with the trend of intergroup conflict sanctioned by high status
members will be exhibited by low status members as a means of improving their status within
the group.
This hypothesis could be tested empirically by comparing the reactions of low status members
toward the out-group (a) when in the presence of in-group members high in status and (b)
when high status members of their in-group are not present. Since the primary concern of
Stage 2 in this present experiment was the end products of intergroup friction, this empirical
test relating to the behavior of in-group members was not made. As stated in Chapter 2, it was
necessary to limit such devices in the present study in order that the interaction processes
within groups and between groups would not be complicated by excessive intervention by
experimenters. The test situations and more precise methods of measurement which were
used during Stage 2 were all devoted to tapping the end products of intergroup friction.
Observational data bearing on this hypothesis cannot be crucial without an empirical test such
as that suggested above. The data available are not contradictory of the hypothesis as
modified. One consistent finding supports it, namely, that in those instances in which low status
members initiated aggressive acts directed toward the out-group, group action followed when
the suggestion was approved or taken over entirely by high status members, and [p. 130]
particularly the leader. Conversely there were instances of suggested aggressive action toward
the out-group initiated by low status members (and even upper status members) which was not
carried out because the leader did not assent to it. The number of raids suggested by various
group members far exceeded the number actually carried out. In every case the leader decided
on the major details of the raid. Mills set the time for both of the Rattler raids, and Mason (who
was the moving force in making the suggestion and in its execution) managed the Eagles'
morning raid on the Rattler cabin, even though Cutler (low status) led the way to the cabin after
the decision was reached.
B
Verification of Observational Findings Concerning Intergroup Friction Through
Laboratory-type Tasks:
Stereotype Ratings and Performance Estimates
In this stage of negative intergroup relations, Hypothesis 1, Stage 2 is crucial:
In the course of competition and frustrating relations between two groups,
unfavorable stereotypes will come into use in relation to the out-group and its
members and will be standardized in time, placing the out-group at a certain social
distance (proportional to the degree of negative relations between groups).
This hypothesis goes to the core of issues concerning the formation and standardization of
prejudice of social distance scales in relation to out-groups that prevail in actual social life.
The main events between groups in this stage were manifested through rivalry and actual
conflict. Our emphasis in formulation of the crucial hypothesis was on end products in the form
of standardized norms relating to the out-group, rather than on specific events revealing
conflict, fights, and rivalry. If negative functional relations between groups are more than
momentary affairs and give rise repeatedly to fights and hurling of derogatory terms, the end
products will be standardized generalizations concerning the out-group which are expressed in
the form of unfavorable p. 131] stereotypes. These standardizations constitute the basis of the
institution of group prejudice or social distance. Once standardized, such institutions
crystallized in negative stereotypes outlast the actual state of negative relations, henceforth
predisposing in-group members to categorize out-group members in the light of unfavorable
generalizations even at times when the acts of out-group members are not of an unfavorable
character. Therefore, our emphasis in formulating hypotheses concerning negative relations
between groups has been on negative generalizations concerning the out-group, i. e.,
standardized stereotypes, rather than on a syllabus of behavioral items revealing hostility,
aggression, and other expressions of intergroup conflict.
As the account of interaction during Stage 2 indicates (Chapter 5), there were many specific
examples of conflict, in which members of the two experimental groups had to be separated,
much name-calling of the out-group, much use of derogatory terms and ridicule. Briefly, one
end result of competition and rivalry in a series of contests and of situations in which the
behavior of one group was frustrating to significant aims or goals of the other was a desire
manifested by both groups to have nothing further to do with each other. With the assumption
that generalizations concerning the out-group and attitudes toward it would outlast the state of
actual conflict which engendered them, the two groups were brought within hearing distance of
each other after a full day of exclusively in-group association. The result was repetition of the
name-calling, derogation, and other manifestations of attitudes revealed during the period of
intergroup conflict itself. This was the critical time to tap these end-products of intergroup
conflict through more precise laboratory methods to check further the validity of the
observations. This was done on the following day, two days after the end of the tournament and
the climactic raid by the Rattlers. The two experimental units undertaken at that time are
reported on the pages that follow.
1. Verification of Stabilized In-Group and Out-Group Attitudes Through Judgmental
Indices: Stereotype Ratings.
At the end of Stage 2, judgmental ratings of stereotypes [p. 132] actually used by the subjects
in relation to out-groups were obtained. This unit was carried out to provide a further test of
Hypothesis 1, Stage 2, namely, that unfavorable stereotypes will arise in relation to the out-
group and its members as a consequence of competitive and frustrating relations between the
two groups, and will become standardized in time.
The procedures for this unit were repeated at the end of Stage 3. A comparison of the data
obtained at the end of Stage 2 with those obtained at the end of Stage 3 provides a crucial test
of the prediction that cooperative efforts in situations embodying superordinate goals will have a
cumulative effect in reducing intergroup tensions (Hypothesis 1b, Stage 3). This comparison is
presented in Chapter 7 with the summary of Stage 3.
The judgments were obtained in this experimental unit to supplement data from observers'
reports and to provide a more clear-cut check of the hypothesis stated above. No new
hypotheses are tested separately by this experimental unit. Throughout the entire study, results
obtained by as many methods as feasible are brought together to test a particular hypothesis.
In this particular instance, judgments of in-group and out-group members are used as further
evidence for conceptual products (stereotypes) of intergroup interaction under conditions of
competitive rivalry. The hypothesis is to be evaluated in terms of all relevant evidence obtained,
including observational and sociometric data summarized in the last chapter and in this chapter,
and judgmental data presented below.
In reviewing the problem of prejudice, Sherif (1948) emphasized that prejudice and stereotypes
held toward out-groups are products of past or present relationships between the groups in
question.
The favorable or unfavorable properties or 'traits' attributed to 'they' groups, and
inevitably to their individual members in a rather absolutistic way, are determined by
the nature of positive or negative relations between the groups in question. If the
interests, direction, and goals of the intergroup relations are integrated or in
harmony the features attributed to 'they' groups are favorable. If the activities and
views clash while the interacting groups pursue their peculiar interests and goals,
the features attributed are negative (p. 357).
[p. 133] The intergroup relations of such small groups as gangs show this in a striking way. In
the process of group formation there is a tendency to appropriate certain areas, objects, places,
etc., as their "own. " Encroachment or invasion of these private domains by an out-group
results in clashes which tend to be accompanied by attribution of unfavorable characteristics to
the "intruders." If the relationship of conflict endures for any length of time, derogatory terms for
the out-group become standardized which mirror the nature of the underlying attitudes of
prejudice or social distance.
When stereotypes become standardized with an in-group, they may and do persist beyond the
functional relationships between groups of which they are a product. Existing stereotypes may
then be manipulated by powerful members of the in-group or, at times, by other interest groups
and extended to groups with whom there has been little or no contact. However, the present
experiment on intergroup relationships is concerned with studying stereotypes from scratch,
that is, tracing their formation from the time of first contact between groups in conditions of
rivalry through a period of intergroup conflict. Therefore, those studies which reveal differential
response to contact with out-groups under varying conditions of interaction were especially
pertinent in formulating our hypotheses.
A survey of historical studies in various countries reveals that social distance scales do reflect
the nature of intergroup relationships in which they evolve and that over a period of time they
are responsive to altered conditions of intergroup interaction (Note 1). For example,
MacCrone's intensive historical study tracing intergroup relations and social distance attitudes
in South Africa during a period of over 200 years (1937) shows "radical alteration" of attitudes
of original European settlers, who originally placed natives in the "heathen" category, which
offered at least the possibility of salvation. As a consequence of active efforts to utilize native
labor, reactions of native groups to these efforts, importation of more docile groups as slaves,
and many actual intergroup conflicts, as well as developments external to the area itself (e. g.,
expansion of imperialism, industrial developments, etc. ), contemporary emphasis on "the white
man and his civilization" in contrast to "inferior" native groups began to emerge in the early 19th
century.
Klineberg's summary (1950) of changing stereotypes of the [p. 134] Chinese by Americans on
the West Coast at different periods in American history is particularly illuminating. When there
was a great demand for Chinese labor, and thus, conditions of interdependence between
Chinese and white settlers, favorable verbal pictures of Chinese were common in journals and
newspapers. However, around the 1860's, when other groups began to compete strongly with
Chinese for their positions, descriptions of the Chinese began to undergo a radical shift in the
negative direction. Whereas they had been described earlier as "thrifty," "sober," "inoffensive, "
and "most worthy" adopted citizens, the stereotype held of the Chinese became negative. The
Chinese who had earlier been seen as possessing "adaptability beyond praise" now were
pictured as "a distinct people" who were "unassimilable," "debased," "servile," etc.
Experimental evidence supporting the view that stereotypes arise as products of functional
relationships between in-groups was provided in Sherif's 1949 experiment on intergroup
relations (Sherif, 1951, Sherif and Sherif, 1953). The design of the last two phases of that study
was the same as that of Stages 1 and 2 of the present experiment (see Chapter 2). The
hypothesis tested in the final phase of the 1949 experiment was essentially the same as our
main hypothesis for Stage 2. In the course of interaction in intergroup situations of competition
and frustration highly derogatory labels were used in relation to the out-group. In time such
terms as "pig," "bums," and "cheaters" were standardized for reference to members of the out-
group.
Utilizing such leads from the 1949 intergroup experiment, Avigdor (1951) carried out her
doctoral study at New York University on the specific problem of "The spontaneous
development of stereotypes as a result of a specific type of group interaction." By subtle control
of conditions, Avigdor was able to create first a relationship of cooperation between small
groups and later to turn this relationship into one of unfriendliness between certain of the
interacting groups.
Groups of l0-year-old girls ("friendship clubs") were paired by Avigdor (who became an adult
leader of the groups for the purpose of the experiment) in both cooperative and competing
activities. The cooperative situation was one in which a compelling common goal existed for
each of the paired groups, that of earning enough money to purchase highly desired club
jackets. Attainment of this goal required that two groups work together to put on [p. 135] a play.
At the height of the cooperative activities each group rated the other cooperating group on 32
characteristics, half favorable and half unfavorable, on a five-point rating scale.
The conflict situation developed when two of the cooperating groups were more successful in
preparation of their play than the other groups. Intergroup conflict reached such an intensity
that when one group which was lagging behind was brought to a final rehearsal of the play
being prepared by two more successful groups, the visitors became objectionable and were
forcibly expelled. At this point ratings on the 32 characteristics were obtained from members of
the rival group in relation to the two groups which had expelled its members, and from
members of those two cooperating groups in relation to the group thrown out.
Among Avigdor's conclusions were that the ratings made after the cooperative interaction were
generalized in the favorable direction, "that is, development of favorable stereotypes," while the
ratings obtained after interaction involving conflict generalized in the unfavorable direction, "that
is, development of an unfavorable stereotype" (p. 65).
In one aspect of an experimental study of negative and positive relations between small groups
existing in everyday life, Harvey (1954) obtained results in line with those reported above. He
found that when the interacting groups were positively related preponderantly favorable
adjectives were attributed to the out-group and its members. But when the relationship between
groups was negative, derogatory adjectives were used in relation to members of the out-group.
Before presenting results of stereotype ratings obtained in the present experiment, it should be
stressed that negative relations between groups with accompanying patterns of social distance
and negative stereotypes do not imply that a similar pattern of relationships prevails among
members of the in-group. There is evidence from the present intergroup study, as well as from
the 1949 study and sociological fieldwork, to indicate that conflict with an out-group tends to
result in increased in-group solidarity with consequent favorable verbal pictures of in-group
members. (This significant point was elaborated in relation to Hypothesis 2, Stage 2.)
[p. 136] The results of stereotype ratings by Eagles and Rattlers of their own groups and of the
respective out-group provide a critical check of the validity of conclusions based on
observational data, namely, that unfavorable stereotypes in relation to the out-group were
produced as a consequence of competitive and frustrating relations between experimentally
formed in-groups.
Procedure:
At the end of Stage 2, the two experimental groups, Eagles and Rattlers, were asked to make
ratings of their own and each others' group. It was explained to the subjects that they were
being asked to do this to help the administration find out what they thought of their new
acquaintances and how they were enjoying camp.
The stereotype scale contained critical characteristics as well as uncritical or favorable ones,
and a five-point rating scale for each of the terms. The five points or categories were the same
as those used by Avigdor, via., "All of the (Rattlers or Eagles) are. . .," "Most of the ___ are. . .,"
"Some of the ___ are. . .," "A few of the ___ are. . .," and "None of the ___ are. . .". The subject
made his rating on each characteristic by writing that particular term in the one of five
incompleted categories that, in his opinion, was the most appropriate description of the group
being rated, in-group or out-group.
The characteristics on which in-group and out-group were rated were not postulated merely on
a priori grounds. They were terms that the subjects themselves had used during Stage 2. Thus
there was some assurance of the appropriateness of the characteristics chosen. Although more
terms were presented on the scale, six were chosen as critical ones. It was thought that these
six characteristics were sufficiently standardized in both groups to provide a clear-cut distinction
between in-group and out-group ratings. The critical characteristics included three favorable
terms (brave, tough, friendly) and three unfavorable ones (sneaky, smart alecs, stinkers).
Results:
The frequency of ratings on the six characteristics (brave, [p. 137] tough, friendly, sneaky,
stinkers, and smart alecks) within each of the five categories ("All of the ___ are. . .," "Most of
the ___ are. . .," "Some of the ___ are. . .," "A few of the ___ are. . .," "None of the ___ are. . .")
was determined. The categories were then numbered from 1 to 5, 1 being the most unfavorable
and 5 the most favorable category. Thus a response of "All of the ___ are (unfavorable term)"
would go into category 1, while a response of "All of the ___ are (favorable term)" would be
tabulated in category 5. The results are presented in terms of ratings on the six characteristics
combined.
Table 3 presents the ratings of out-group members by each group at the end of Stage 2
(friction stage).

[p. 138] These results confirm observational data indicating that members of both groups
tended to rate the out-group unfavorably following the stage of intergroup competition and
friction. Fifty-three per cent of the ratings made by the Rattlers were negative and 24.9 per cent
favorable. The Eagles' favorable picture of the out-group is even more accentuated. Their
ratings of the Rattlers were 76.9 per cent unfavorable and only 15. 4 per cent favorable.
Table 4 presents a composite picture of the ratings six characteristics made by Rattlers and
Eagles of their groups (in-groups) at the end of Stage 2 (friction).

From these results it can be seen that at the end of Stage 2, in which conditions gave rise to
intergroup friction, members of both the Rattler and Eagle groups were rated favorably by other
members of their respective in-group. While the tendency was to rate out-group members
unfavorably at this stage (Table 3), there was an even more pronounced tendency to rate in-
group members favorably (100 per cent favorable ratings of in-group by Rattlers and 94.3 per
cent favorable ratings of in-group by Eagles). [p. 139]
The accompanying figure presents the main findings in graphic form. Ratings of the out-group
by both Eagles and Rattlers are significant in the unfavorable direction; ratings of in-group by
both groups are significant in the favorable direction. And, as noted above, ratings of in-group
and out-group differ significantly in direction.
Thus, competition and rivalry between the groups led to attribution of unfavorable
characteristics to the out-group, while this same pattern of intergroup relations was
accompanied by a marked tendency to see members of one's own group in a highly favorable
light. This finding is relevant to the prediction of intense in-group solidarity under conditions of
intergroup competition, rivalry and hostility (Hypothesis 2, Stage 2). It constitutes further
evidence that intergroup relations do not necessarily [p. 140] follow the same pattern as in-
group relations, particularly when the relationship between the interacting groups is one of
rivalry and antagonism.
On the basis of both observational and sociometric data, and evidence in this unit, Hypothesis
1, Stage 2 is supported. During the course of competition and frustrating relations between the
experimentally formed groups, unfavorable labels were assigned to the out-group and its
members and were used and shared to varying extents by members of the in-group. Social
distances crystallized in these standardized derogations were great enough that for a time
members of each group expressed a strong desire not to associate in any way with the out-
group or its members (see Chapter 5).
2. Verification of Stabilized In-Group and Out-Group Attitudes Through Judgmental
Indices: Performance Estimates.
At the end of Stage 2 (intergroup friction), a second experimental unit was introduced to obtain
further evidence of the products of prolonged negative interaction between the two
experimentally formed in-groups. In this experiment, direct judgments of a numerical nature
were obtained in such a way that they might reflect the character and intensity of intergroup
relations after a period of competition, rivalry and friction between the two groups. Members of
both experimental groups made judgments of items presumably accumulated by members of
their own in-group and by members of the rival out-group while performing a task for which the
winning group would be rewarded.
It was proposed that negative intergroup relations would produce in time derogatory
conceptions (stereotypes) of the out-group accompanied by intensified in-group solidarity and a
highly positive picture of the in-group. Further it was proposed that the deprecatory picture of
the out-group and flattering picture of the in-group would be internalized by individual members
as negative attitudes toward the out-group and positive attitudes toward the in-group, and that
these would be revealed
(a) in their ratings of in-group and out-group on significant characteristics embodied in the
stereotypes (see [p. 141] preceding section), and
(b) in judgments of the performance by members of the in-group and out-group on a relevant
task.
The task chosen for the latter purpose was a bean toss contest, judgments of the number of
beans presumably collected by each individual being made after the contest.
Specifically it was predicted that as a consequence of intergroup competition, rivalry, and
hostility:
In-group members will tend to overestimate the number of items purportedly
obtained by in-group members and underestimate the number of items attributed to
out-group members (Hypothesis 1 a, Stage 2).
The data from this experimental unit are to be evaluated in conjunction with observational
findings showing increased glorification of the in-group and its members and deprecation of the
out-group as a consequence of intergroup rivalry and conflict (Note 2). The judgmental indices
obtained should reflect this state of affairs reported by observers and are intended to
supplement their findings, not to replace them.
The plan to obtain experimental measures of attitudes formed toward the groups by the end of
Stage 2 represents an extension to the level of intergroup relations of a basic psychological
principle underlying the conception of this entire study, namely, that all psychological activity is
determined by the frame of reference within which it occurs (Chapter 2). The frame of reference
consists of the totality of functionally related factors, external and internal, that operate
interdependently to determine the psychological reaction at any given time. The relative weights
of the external and internal factors in determining psychological activity are not necessarily the
same in different instances. The relative weight of these factors varies with the degree of
stimulus structure and the nature and intensity of internal states at the time. When stimulus
conditions are compelling in structure, the effects of internal (e. g., motivational) factors in
patterning perception and behavior are not readily apparent; but under conditions of minimum
stimulus structure, of ambiguity or flux, internal factors operating at the time may be clearly
reflected in the subsequent behavior. Therefore, in attempts at studying [p. 142] motivational
factors through their influence on the patterning of perceptual and judgmental responses,
stimulus conditions should be both appropriate and sufficiently unstructured that the nature of
the motivational factors can be revealed through the resulting behavior.
Since the presentation of the foregoing formulation (Sherif, 1935), there have been a number of
studies investigating various motivational factors through their influence on such processes as
perceiving and judging. The distinctive feature of the present experiment is that judgments are
used as indices of the relationship between experimentally produced in-groups.
In Sherif's 1949 intergroup relations experiment, in-groups and negative relationships between
them were produced through controlling conditions of interaction in essentially the same way as
in this 1954 experiment. It was observed that as a consequence of the negative relationship
between groups, in-group members extolled and maximized the performance of in-group
members while deprecating and belittling the performance of members of the unfriendly out-
group. Attention was called to the feasibility of obtaining precise experimental indices of
intergroup relations through their differential effects on the perception and judgments of
individual members. Judgments and perceptions of individual members will reflect the influence
of membership and participation in the on-going activities of the group.
This being the case, the effects of the group situation, and the changes brought
about in attitudes toward the in-group and the out-group and their respective
members, can be studied in terms of precise laboratory experiments, such as the
currently accumulating judgment and perception studies. This will constitute a
significant advance in method over observation of actual behavioral events alone.
The actual behavioral events are more difficult to observe with precision and
present baffling problems in their ordering along definite dimensions. If the
psychological significance can be epitomized and measured in terms of
representative judgmental and perceptual situations, we shall be achieving a
methodological gain close to the laboratory level. (Sherif, 1951, p. 422).
This proposed method of studying group relations through [p. 143] judgmental indices was
applied to a study of status relations within groups that already existed in everyday life (Harvey,
1953). It was found that judgments of future performance of group members provided an index
of their relative status positions within the group. Owing to the differential expectations that had
become standardized for each status position, performance of high ranking members tended to
be overestimated, while that of lower ranking members was estimated significantly less, even to
the point of underestimation of actual performance.
The same methodological approach was applied in our 1953 experiment on intergroup relations
to the study of status relations in experimentally produced groups. Going a step further, that
study tapped the differential expectations for members occupying positions in a status structure
which was itself experimentally produced (Note 3). Members of the experimental groups judged
the performance of in-group members on the task of throwing handballs at a target board which
was designed so that there was little indication of actual performance. The status positions that
had evolved during the period of group interaction were reliably revealed in the subjects'
judgments of other members' performance made immediately following each throw. The
performance of higher ranking members was judged significantly higher than that of lower
ranking members.
More recently this technique was extended to the study of negative and positive relationships
between small groups existing in everyday life. Harvey (1954) showed that the relationship
prevailing between interacting groups is revealed in the judgments of group members under
appropriate stimulus conditions. Performance actually achieved by each subject, i. e., the
names of cities written under conditions of distraction, were projected on a screen too briefly for
actual count, and the number was judged by both in-group and out-group members. When
intergroup relations were negative, the tendency was to judge the performance of in-group
members at a significantly higher level than that of out-group members.
The present experimental unit is concerned with obtaining judgmental indices of the relationship
between two groups which were experimentally produced and which came into conflict as a
consequence of experimentally introduced conditions of competition and frustration.
[p. 144] Procedure:
Members of the two groups (Eagles and Rattlers) participated in a bean toss contest under
strongly competitive conditions and then made judgments of the number of beans collected by
each in-group and out-group member as the purported performance of the particular individual
was projected on a screen by an opaque projector.
The contest was held after the tournament and various raids of Stage 2 (see Chapter 5). Social
distance between the groups was sufficiently great that neither wanted to be in a situation with
the other. They entered into this contest when told that the staff members of their respective
groups had made a wager on the outcome and as they began to anticipate the five dollar
reward offered to the winning group. Before the contest, the leader of the Eagle group predicted
darkly, "It will turn into a gang fight." In spite of this initial resistance, both groups participated in
the contest with considerable zeal once it was underway.
The beans were spread in equal density in two marked-off areas of similar size. The Rattlers
picked up beans from one area, while the Eagles gathered beans from the adjoining area (see
Figure). Separate areas were used to prevent pushing and shoving of out-group members. The
time allowed for picking up beans was one minute. Pre-tests with comparable subjects before
the experiment showed that one minute permitted the collection of 25-40 beans. To prevent the
subjects from exceeding this range and to limit possibilities of their counting the beans
collected, each was given a small brown paper sack, the open end of which was gathered
around a hollow rubber tube with a half-inch opening. Subjects were instructed to pick up only
one bean at a time and put it in the sack through the half-inch opening. Thus speed of
performance was at a premium. They were instructed not to count the beans, that this would be
done later, and were told that everyone would judge the performance of everyone else. The
judgmental aspect of the task which was actually the crucial one for this unit, was presented as
a regular part of the bean toss contest.
After the beans had been collected, the subjects went to an experimental room (large
recreation hall) where the beans collected of each member of both groups were purportedly
projected by an opaque projector and judged by both in-group and out-group
[p. 145] members. Actually the same number of beans (thirty-five) was projected every time as
the performance by every individual in the two groups. The number chosen had been found in
pre-tests prior to the experiment to be the optimum number for the brief exposure time used (5
seconds). It was necessary that the number of items projected should exceed the perceptual
span (should be too great to count in 5 seconds), but at the same time be few enough that the
subjects would feel that if they had tried just a little harder they could have finished the count. If
the actual number could have been accurately established by the subjects, obviously there
would have been no indication of motivational factors in their judgments.
The experimenter made it appear that he was putting in new beans to be projected each time,
but the same ones were retained for every projection. The experimenter moved the location of
some of the beans each time only slightly. Therefore, the form of the projection (circular)
remained essentially the same, but the pattern was slightly different from projection to
projection.
By a toss of a coin, it was determined that the performance of members of the Eagle group
should be projected and judged first. Before the purported performance of each boy was
projected, the experimenter called his name and the boy stood up so that both in-group and
out-group members would know exactly whose performance was being judged. The subjects
wrote their judgments on small pads of paper. Each boy wrote down the name called out. When
the biggest of the Rattlers was called off, "Red Brown, "one of the Eagles (Wilson, a lieutenant)
said, "I'm just going to put Red Bum on mine."
Results:
To test the hypothesis, it was necessary to ascertain the extent to which the performance of
each in-group and out-group member was over- or underestimated and to compare these mean
differences. Since the same number of items (35) was projected as the performance of each
subject, this constant was subtracted from each judgment of performance. Means of these
differences were then computed for judgments of performance by in-group members and by
out-group members. The differences between the means were subjected to the t-test, using the
formula for correlated means. Results of this analysis are given in Table 5.

Rattlers 3.404 -.293 3.697 3.452 <.01
Eagles 4.556 11.802 7.246 4.609 <.01
From this table it can be inferred that the performance of in-group members was judged
significantly higher than that of members of the out-group. The Rattlers' mean discrepancy for
judgments of performance by in-group members was 3.404 and that by members of the out-
group (Eagles) was -- .293. Thus while members of the Rattler group overestimated the
performance of in-group members, they tended to underestimate the performance of negatively
related out-group members. (When the beans supposedly collected by the leader of the
Rattlers were projected, a member of his group whistled appreciatively.)
Members of the Eagle group greatly overestimated the performance of in-group members
(mean discrepancy of 11.802) and overestimated the performance of out-group members
significantly less, although not to the point of underestimation reached by the Rattlers in their
judgments of the Eagles' performance. (Perhaps the Eagles' recent victory in the tournament
over great odds had something to do with this difference.)
For both groups, the performance of in-group members was judged significantly higher than
that of out-group members. The results cannot be explained in terms of differences in actual
performance:
(a) Since speed was the crucial factor each bean had to [p. 147] be inserted through a small
opening in the bag, individuals did not have an opportunity to observe each others'
performance.
(b) The number of items projected as the performance of each individual in both groups was
identical, in all cases being thirty-five.
These results are concordant with observational findings concerning the valuation of in-group
members and deprecation of members of the out-group, and with sociometric findings which
revealed a preponderance of in-group choices. Therefore, it can be concluded that the results
reflect the solidarity within groups and negative attitudes toward out-groups at the end of Stage
2. Data from this unit also support the hypothesis that, as a consequence of intergroup
competition and conflict, in-group members will tend to overestimate the performance of
members of their own group and will tend to deprecate the performance by members of a rival
out-group.
The findings indicate that conceptions of the in-group and out-group can be tapped
experimentally through judgments obtained from individual members of the functionally related
groups. Their larger significance bears on the individual - group relationship. They point again
to the fallacy of dichotomies between the individual and the group. Here the relationship
between groups, a phenomenon at the group level, has consequences not only for the
formation of values or social norms within the group, but for the perception and judgments of
individual members as well.
********
Summary of End Products of Intergroup Friction
As a consequence of repeated interaction between the two experimentally formed groups in
competitive and reciprocally frustrating situations, and of the cumulative intergroup friction thus
engendered, negative attitudes toward the out-group were formed by members of each in-
group. These negative attitudes toward the out-group, crystallized in unfavorable stereotypes,
were manifested by name-calling, derogation of the out-group, and the explicit desire to avoid
association with the out-group (see observational data summarized in Chapter 5). In order to [p.
148] check these observations and to ascertain that they indicated more than merely
momentary reactions in intergroup conflict situations, an entire day was devoted to in-group
activities following the close of actual competition and conflict between the groups. On the day
following this, attitudes toward in-group and out-group were tapped through (1) sociometric
choices, (2) stereotype ratings of the in-group and out-group, and (3) judgments of performance
by in-group and out-group members in a competitive task (bean toss contest). Analysis of these
results confirms in a more precise way the observational findings. The methodological
importance of this correspondence between observational and judgmental data is two-fold.
First, it provides a check on the validity of conclusions reached. Second, it indicates the
possibilities of utilizing judgments of in-groups and out-groups as indices of the state of affairs
prevailing on the level of group relationships.
The methodology stems from the approach to the study of the complex processes of interaction
in intra- and intergroup relations stated in Chapters 1 and 2. On the one hand, it is feasible to
set up the flow of interaction processes in a life-like, natural way; on the other hand, validity and
precision can be insured through obtaining data by observation (looking from without), by
sociometric techniques (looking from within) and by the introduction of precise laboratory-type
experiments at choice points. In our opinion, only through the use of such a combination of
methods, applied to the flow of interaction process without chopping it into disjointed pieces,
can we hope to attain generalizations with some bearing on the persistent group problems of
actual life situations. If we follow such an approach in testing hypotheses, we are less likely to
be troubled with the problems of validity which plague so many current studies in this area.
From a theoretical point of view, the results of these experimental units, carried out after actual
intergroup conflict had ceased, indicate that events occuring between groups have
consequences at both a group level (norms relating to the out-group) and at a psychological
level (formation of negative attitudes toward the out-group), and that these consequences
outlast the intergroup events themselves.
The crucial question which remains to be answered is whether or not changes in the character
of relationships between groups, wrought through altering the conditions in which the groups
interact [p. 149] from those conducive to friction to those of interdependence, will result in
reduction of friction between groups and changes in negative attitudes and stereotypes
standardized in relation to the out-group. This question was the point of departure for Stage 3
of this experiment, to which the next chapter is devoted.

2. It had been planned to repeat this experimental unit and the stereotype ratings at the end of
Stage 3 to secure further evidence of the differential effects of intergroup cooperation toward
superordinate goals. However, it became evident that a repetition of this unit and of the
stereotype ratings too would yield most direct evidence with least cluttering of the on-going
trend of Stage 3.
3. The plans for the 1953 study called for utilizing the same methods to tap attitudes toward in-
group and out-group after a period of intergroup friction. However, this unit was not undertaken
until the present 1954 study.

Intergroup Relations: Reducing Friction (Stage 3)
A. Approach to Reducing Friction
At this stage of the experiment, the main objective of our study could be undertaken, namely
the reduction of intergroup friction. There are now two distinct groups in an unmistakable state
of friction with one another. The groups exhibited in word and deed repeated hostility toward
one another; they standardized unflattering attitudes and stereotypes toward one another.
The derogatory attitudes toward one another are not the consequence of pre-existing feelings
or attitudes which the subjects had when they came to the experimental site. They are not the
consequence of ethnic, religious, educational or other background differentiation among the
subjects. Nor are they the result of any extraordinary personal frustration in the particular life
histories of the subjects, or of marked differentiation in physical, intellectual or other
psychological abilities or characteristics of the subjects. Possible effects of such differences
were carefully ruled out in the laborious procedures used in subject selection (Chapter 3).
The state of friction was produced systematically through the introduction of conditions of rivalry
and frustration perceived by the subjects as stemming from the other group. By the end of
Stage 2, as we have seen, the intergroup friction was crystallized in some unfavorable
stereotypes and in the repeatedly expressed desire to have nothing more to do with the other
group. To be sure, the words and deeds of hostility, the unflattering stereotypes towards the
out-group, the self-righteousness of the in-group were not expressed with the same
determination, the same vehemence, the same degree of feeling by any two group members.
But, whatever the differentiating degree or intensity in the unique personal manifestation of
hostility, the general trend of negative attitude toward the out-group was a common property of
all group members. The intergroup hostility was prevalent despite the occurrence of occasional
interpersonal rivalry, bickering and friction in the relations within each group. Two boys who
engaged in some interpersonal exchange of unfavorable reactions toward one another, at a
given time, would join hands a few minutes later in a [p. 152] concerted, common front in
carrying out the developing intergroup trend in relation to the out-group. It should also be
remembered that the in-group identification and solidarity in in-group and intergroup relations
exhibited by in-group members did not stem from pre-existing interpersonal ties. The boys were
not even personally acquainted with one another prior to the study. The two in-groups
themselves were experimentally produced from scratch in the manner reported in Chapter 4.
It would have been a relatively easy task to bring about positive relations or harmony between
groups right after the formation of the two in-groups. We deliberately postponed this positive
step in intergroup relations until after the unpleasant task of producing a state of friction,
because the vital issue of intergroup relations in the present-day world is the reduction of
existing intergroup friction.
The general character of the alternative chosen in our attempt at reducing friction was stated in
Chapter 2. In short, the alternative of appeal to a common enemy, which was effectively used in
our 1949 study because of expediency at the time, was not used. The unification of groups
against a "common enemy" necessarily implies widening the area of conflict.
The alternative of reducing tension by disintegrating the groups as units through devices which
make individual "shining" and rivalry supreme without concern for the other fellow was rejected.
By following such an approach, we would be destroying the property of intergroup relations
which makes its study so crucial today, namely, the relations between group units.
Likewise, the alternative which emphasizes exclusively the role of leaders in change misses the
mark, because the effectiveness of leaders, even though weighty, is not unlimited. Leaders are
not immune to influences coming from the rank-and-file, once a group trend starts rolling, even
though initially the leaders might have been largely responsible for starting the trend.
With such considerations in mind we chose the alternative of introducing common,
superordinate goals of sufficient appeal value. But before doing this, we studied the possible
effect of mere intergroup contact situations as equals, because there are adherents of this
approach both in academic and practitioner circles.
[p. 153] At this point a word of clarification concerning the concept "contact" will be helpful. The
word "contact" has flexible denotations which allow it to become a blanket term. It could be
used to refer to any kind of interpersonal or intergroup interaction which is within the actual
perceptual range. In customary usage, the word "contact" in intergroup relations refers to
having individuals from different social, ethnic, or national backgrounds come together on some
specific occasion, such as a tea party, lecture, dinner, or dancing party. We are using the term
"contact" in this customary sense and reserving the concept "interaction" for broader generic
reference.
We shall report the intergroup contact situations and their results in the next section. The
common superordinate goal situations and their products are presented in section C.
B. Intergroup Relations: Contacts Introduced to Reduce Friction
The first part of Stage 3 was devoted to a series of contact situations varying in duration from
about 15 minutes to an hour or so, and differing in the character, such as (a) participating
together in a psychological experiment with opportunity to interact before and after the
experiment, (b) attending a movie together, (c) having meals together in the same mess hall
with utmost freedom to choose seats and interact with anyone in any way desired.
Essentially the same general procedure was followed in each of the contact situations. The two
groups were taken to the place of contact (for example, the recreation hall or mess hall), both
groups arriving at the same time or one shortly after the other, and then they were left to their
own devices. Once the groups were in the contact situation, the staff walked away from the
immediate contact range and pretended to be engaged in some activity, such as sitting under a
tree in conversation. In no contact situations did the Eagle and Rattler staff members associate
with one another during the period while the contact situations were being initiated and carried
out.
The first contact situation was during the second part of the "bean toss" experiment, in which
the subjects were to estimate individually the projected number of beans supposedly picked up
by each of the subjects in both groups. The first part of the experiment consisted of picking up
as many beans as possible in a [p. 154] unit of time. (See description of this experiment at the
end of Chapter 6). Each group was strongly opposed to taking part in the "bean toss"
experiment because it involved association with the other group. Even a prize of $5 for the
winners was not very effective at first in reducing the resistance of the groups.
Later in the day during a Rattler cookout at Lake Carlton it was announced to them that they
had won the bean toss contest and they were given the prize, a $5 bill. They were told they
could spend it any way they liked. Assent was unanimous to the first suggestion to the effect
that they spend their $5 for the repair of one of their two boats which they had been unable to
use for several days because of a leak.
The Eagles, especially, were dead set against participating in any activity which had anything
whatsoever to do with the Rattlers. In an early morning swim that day, the Eagles had
discovered their flag in the water, burned the previous evening by the Rattlers. Upon making
this discovery, they denounced the Rattlers as "dirty bums," and accused them of having put
ice in the water (because it appeared to one of them as colder than usual), and of throwing
rocks in their creek (because one of them stubbed his toes a number of times during the swim).
Shortly after the beans were collected as one aspect of the experiment, both groups were
instructed to come to the recreation hall to estimate the number of beans each "picked up."
Two sets of four rows of benches were arranged for subjects during the experiment, only a
narrow aisle of about one yard separating the two sets of benches (see pictures, last part of
Chapter 6). When both groups arrived in front of the building, they were told to wait there for a
short time until the apparatus was fixed. During the wait there was some bantering back and
forth between the groups about who had won the tournament. During this waiting period the
staff kept away from the groups. When the staff gave the signal to enter (addressed to no
particular group), the Rattlers went in the building first. One of the Eagles remarked, "Ladies
first." Until the last days of Stage 3, when the Rattlers went in first on such occasions, this
"Ladies first" remark was made by the Eagles. The Rattlers took the front seats, leaving the
back seats for the Eagles, thus producing seating arrangements strictly along group lines.
There were jeering, cat-calls and insulting remarks as the [p. 155] proceedings permitted.
During the event, Mason (E) warned Simpson (R) to stay out of the Eagles' swimming hole.
When the beans which were supposed to be Mills' (R leader) were projected, Everett (R) said
"Whew!" and several other Rattlers whistled, presumably in respect. It will be remembered that
the number of beans projected for all subjects was exactly the same (35 in each case). Toward
the end of the event, a Rattler noticed that the pencils were "Eagle" brand, and dropped his,
saying in a loud voice that he did not want to touch anything that had anything to do with the
Eagles. Most of the other Rattlers followed suit. When the affair was over the groups parted
yelling insults at each other. The outstanding among these were Eagles calling Rattlers "Dirty
Bums," and Rattlers calling Eagles "Sissies" and "Babies."
The second contact situation took place about half an hour later before the first stereotype
rating session. Neither group appeared to be pleased with the prospect of participating in this
task in the company of the other group. The Rattlers felt positively insulted at being asked to do
so. The same procedure of a short wait for both groups in front of the building was followed.
When they were asked to come in, with no indication of which group was to enter first, the
Rattlers again entered first, eliciting the "Ladies first" remark from the Eagles. The response to
this remark was derisive. The tables for this event were arranged in a V-shape, something that
had not been done before. This was done so that position habits would not determine that the
groups sit separately, and in their accustomed eating positions. The seating arrangement was
strictly along group lines. Again there were no signs of intermingling, but there were complaints
about the Eagle pencils and derogatory remarks hurled, especially by Rattlers.
The rest of the day was spent in in-group activities. The Rattlers had their lunch at Lake
Carlton, the public picnic ground about two miles south of the camp grounds. The picnic area
was full of outside people. The Rattlers' dealings were almost entire within their in-group. The
Eagles had lunch at the usual camp mess hall. The Eagle participant observer intentionally sat
down at the Rattlers' table to see what would happen. Only Bryan came to sit beside him.
Wilson shouted to him to get up because he would get all dirty sitting at that table. Bryan got up
and brushed his clothes off.
[p. 156] The third contact situation was before supper in front of the mess hall. Both groups
waited in close proximity, the pretext for the wait being that the food was not yet ready. The
staff again withdrew from the scene. While waiting, an argument arose as to which group was
the best, and invectives were exchanged. When a neutral party gave the signal that the food
was ready, the Rattlers started in first, accompanied by the Eagles' now standardized remark:
"Ladies first." The Rattlers were in the mess hall quite a while, but the Eagles were not making
a move to go in as they usually did. Seeing this, the Eagle participant observer told them to go
in when they wanted to. The Eagles waited until the Rattlers had all gotten food on their trays.
After the Eagles entered the mess hall, the exchange of unflattering words between the two
groups became louder and louder. The Rattlers lived up to their "tough" boy self-image and
became somewhat vulgar.
Staff stayed outside, talking until supper was half-way through. The row inside increased in
proportion. Both sides were throwing papers and left-overs at each other. This lasted until the
Eagles finished eating and left the hall (at their observer's instructions), followed by yells and
jeers.
The fourth contact situation was centered around the showing of two 15 minute films, both
devoted to maritime topics. The procedure of a joint wait in front of the building (while the
projector was being "fixed") and free choice of seats was followed. The Eagles passed the
Rattler cabin on the way, and were yelled at by Rattlers. The staff moved away. There was
again the exchange of hostile remarks, again the same "Ladies first" remark. During the movie
there was practically no exchange between groups. But there was some exchange during the
change of films. The seating arrangement was strikingly along group lines. When the event
ended, around 9:30 P. M., the staff walked out without telling the boys to leave or anything else.
The boys arose and went out, intermingling. But at the door they completely split - each group
in the direction of its respective cabin.
The fifth contact situation was planned as breakfast the following morning. The positions of the
tables in the mess hall had been completely changed, so that any habitual fixations on a
particular table would be broken. The two tables, which had been placed across the mess hall,
now ran longitudinally; and the staff table was moved to the opposite end of the hall - away
from the [p. 157] boys. (At no meal during any of the three stages did any of the staff members
sit at any of the subjects' tables in the mess hall.) When both groups came in front of the hall,
the counselors and other authority figures withdrew on a pretext. During a short wait an
argument arose as to which group had the most firecrackers. Again a person who had no
authority in the eyes of the subjects announced that breakfast was ready. The same "Ladies
first" ritual followed.
One of the low status Rattlers (Allen) happened to be the first one in front of the Rattler line. He
picked up his food first and carried his tray to the table by the south wall of the mess hall. (The
south side of the mess hall was in the general direction of the Eagle area.) Seeing one Rattler
at that table (for the choice of which there was no facilitation from previous experience), all the
rest of the Rattlers sat at that table. This, of course, determined that the Eagles choose the
table by the north wall of the mess hall. During the meal there was razzing and yelling, but not
as intense as during supper on the previous night. There were attempts at kicking each other
between two different Rattler and Eagle pairs during the course of breakfast.
The sixth contact situation was planned in relation to shooting firecrackers. It was the Fourth of
July. In line with the decision not to appeal to values from the larger setting in achieving
reduction of intergroup friction, and in line with the subjects' preference, separate ceremonies
appropriate to the national holiday were held by each group. However, the shooting of
firecrackers was planned as a special contact situation. On the previous day, the Eagles went
to town as a group and bought firecrackers with their staff. A similar supply of firecrackers was
bought for the Rattlers. Both groups were taken in close succession to a place by the wayside
outside of the State Park area to shoot their firecrackers. (It is prohibited to shoot firecrackers
within the park area, and the camp is within its bounds.) Wilson of the Eagles said that he didn't
want to get out of the truck if they had to shoot their firecrackers with the Rattlers. The subjects
were told that they could shoot their firecrackers with anyone they wanted to. Both groups
started shooting them at about the same time. At no time was there intermingling of the two
groups. At one particular time, Simpson (R) and Clark (E) were closest to one another.
Simpson accused Clark of shooting a rock up in the air and hitting him on the head.
[p. 158] The seventh contact situation: Both groups arrived at the mess hall for lunch at the
same time, as planned. All staff members withdrew from the immediate area of contact. From
that distance, conversation within or between groups could not be heard. Each group stayed on
the side of the mess hall entrance nearest its own cabin. There was no crossing-over between
groups.
When the announcement "food is ready" was made, both groups moved in. This time the
Eagles rushed in first to form the line to pick up trays and food. The Rattlers followed them.
McGraw (E), who was the first person through the line, sat at the same table that the Eagles
had used in the morning after the new table arrangement.
After eating for a while, someone threw something, and the fight was on. The fight consisted of
throwing rolls, napkins rolled in a ball, mashed potatoes, etc. accompanied by yelling the
standardized unflattering words at each other. The throwing continued for about 8-10 minutes,
then the cook announced that cake and ice cream were ready for them. Some members of
each group went after their dessert, but most of them continued throwing things awhile longer.
As soon as each gobbled his dessert, he resumed throwing. As the Eagles were leaving they
shouted at the Rattlers that they would resume the fight at supper, and the Rattlers responded
to this challenge with counter-challenges.
After describing the events summarized above, the Eagle participant observer added the
following comment to his report written that day: "It was apparent by this time that mere contact
between the groups without the introduction of superordinate goals was going to be insufficient
to reduce the negative between the groups." The Rattler participant observer wrote in his daily
report his opinion concerning the inadequacy of mere contact situations in reducing the
intergroup friction and name-calling in much stronger terms.
The intergroup events accompanying and following the series of contact situations summarized
above confirm the following hypothesis:
Hypothesis 1, Stage 3
It is predicted that contact in itself will not produce marked decrease in the existing
state of tension between [p. 159] groups.
[Classics Editor's note: Apologies for the quality of the above images. The "waffle" pattern was
in the source images.]
Accordingly, it was decided to start introducing interaction situations involving common
superordinate goals, instead of situations involving mere contact. In spite of the fact that the
activity engaged in during contacts (such as eating, shooting firecrackers) was gratifying or
pleasing for each individual member within the in-group bounds, the mere fact of contact had
no positive effect toward reducing existing hostility.
C. Intergroup Interaction Involving Superordinate Goals
Thus, contacts which did not involve superordinate goals, in the sense defined at the outset
(Chapter 2), were far from effective in reducing intergroup friction. If anything such contacts
served as occasions for further irritation and for expressing unflattering attitudes of group
against group.
At this point we turned to procedures suitable for testing the main hypothesis concerning the
reduction of intergroup conflict:
When groups in a state of friction are brought into contact under conditions
embodying superordinate goals, the attainment of which is compelling but which
cannot be achieved by the efforts of one group alone, they will tend to cooperate
toward the common goal. (Hypothesis 2, Stage 3)
The present section will be devoted to a summary report of stimulus conditions introduced
which were conducive to the emergence of superordinate goals and to reactions of the subjects
obtained by various measurement techniques. Thus this section includes:
1. A brief account of stimulus conditions introduced for the arousal of superordinate
goals and observational data relevant to the hypothesis stated above.
2. Sociometric choices of group members revealing their attitudes toward in-group
and out-group members and a comparison of these choices with those obtained at
the end of Stage 2.
3. Judgment indices of attitudes toward the respective [p. 160] in-groups and out-
groups in the form of stereotype ratings and their comparison with the stereotype
ratings obtained at the end of Stage 2.
1. Superordinate Goals and Interaction Episodes Related to Them
The Drinking Water Problem: The first superordinate goal to be introduced pertained to
drinking-water at a time when both groups faced the prospect of thirst and became
progressively thirstier with the successive steps of activities directed toward solution of the
problem. In general outline, the plan consisted of having members of both groups perceive
common deprivation which could be alleviated (so it appeared to them) by the cooperation of
members of both groups. Thus a situation of functional interdependence involving a common
goal was produced.
First, a word concerning the preparation of stimulus conditions is necessary. All of the drinking
water in the camp, which is distributed to various parts of the camp (kitchen, latrines, drinking
fountains located near cabins and other convenient spots), comes from a reservoir on the
mountain north of the camp. It is pumped up to the large water tank higher on the mountain
(about 1 1/4 miles from camp) and stored there in sufficient supply for a certain period. A valve
at one end of the tank controls the flow of water and can be cut off to prevent the passage of
water to the main pipe which, as it reaches the camp grounds, runs into various smaller pipes
to the various outlets. (For location of the places and items mentioned above, see the map,
Chapter 3.)
Several hours before the execution of the plan, the valve on the tank was cut off, leaving only
the water already in the main pipe to supply the camp for the time being. After turning off the
valve, two large boulders were placed over it, which had to be removed before the valve could
be turned on again. In addition, the faucet at the end of the tank opposite the valve was stuffed
with pieces of sacking so that no water came from the faucet when it was turned on. The latter
device was planned to require a solution of the problem, since getting a drink when members of
both groups were thirsty would itself have very high common appeal value.
Right after the water was cut off at the tank, the boys were [p. 161] informed by their respective
participant observers that there might be a water shortage in the whole camp as there seemed
to be some trouble with the water system, but that it was being investigated. They advised
members of each group to fill their canteens in case the water shortage became worse. The
boys were told that in the past, on occasion, vandals had tinkered with the water system,
causing difficulties. This warning was given in order that the blame for their thirst not be placed
on the camp staff. After this all of the remaining water was drained out through faucets which
were not within sight of the subjects. (Of course, for any emergency sufficient water was stored
in the small tank in the kitchen both for cooking and drinking purposes. But the subjects did not
know this.)
The execution of the plan was postponed until 4 P. M. so that there would not be much, if any,
water left in the subjects' canteens. Before actual efforts toward getting the water to run again
the topic of the water shortage became a common topic for concern in both groups.
The experimentally planned activities may be summarized as follows: All members of both
groups were present at the announcement of the complete failure of the water system,
depriving the entire camp of drinking water. In order to make the situation real to the subjects,
this took place at the spot where the end of the main water pipe from the tank was visible and
where there were a number of faucets in a row which could be turned on. Thus subjects could
see for themselves that there was not a drop of water coming through.
After the above demonstration the subjects were informed that there was something wrong with
the water system and that the trouble could not be located. They were told that the difficulty
might be a leakage in the pipe between camp and the reservoir, it might be at the pump by the
reservoir, or it might be at the tank. Thus the first step was to find the cause so that necessary
steps could be taken to remedy the difficulty. The announcement went on to say that the help of
about 25 people was needed.
Upon hearing the announcement, members of both groups volunteered to help. The area
between the camp and the reservoir, it was announced, was to be divided into four segments to
be inspected by four different searching details. One staff member would accompany each
detail. It was announced that five boys [p. 162] were needed for the area around the reservoir.
This was the detail to go farthest, and it would be accompanied by an Eagle staff member. The
volunteers that stepped forward for this detail were all Eagles. The detail for the segment
adjacent to the reservoir area up to the tank was to be accompanied by a Rattler staff member.
Volunteers for that detail were all Rattlers. The same alternation was followed for the remaining
two segments with an Eagle staff member and Rattler staff member accompanying the two
details, respectively. Without any exception, each detail consisted of volunteers from the same
group as the staff member accompanying the detail. (A detail of 2 boys and a staff member was
to stay by the faucets in camp for an hour, and then go to report at the tank area.) The details
at the end segments were to move toward the tank area, reporting on the way to the adjacent
detail if they found any difficulty. All groups would congregate at the tank to investigate it if
nothing was found along the way. Thus, the division of the area into segments and alternation
of adjacent segments between Rattlers and Eagles produced a situation of interdependence in
a coordinated activity.
In a little over an hour, all the details from both sides of the tank congregated at the tank, of
course having found nothing wrong on the way. Thus the tank was the only alternative left for
locating the trouble.
The first object to attract attention of everyone in both groups was the faucet at the north end of
the tank, since most of them were thirsty. Some of the Rattlers still had a little water in their
canteens, but the Eagles did not even have their canteens with them. The appeal of water was
great and urgent, especially for the Eagles. (Both groups had come to this faucet for drinking
water during their camp-outs at the reservoir during Stage 1.) Of course, no water came out of
the faucet. The next problem was immediate and compelling: to secure drinking water then and
there. The fact that no water came out of the faucet led to a discussion within and between
groups as to whether there was any water in the tank. During this discussion, there was
pounding of the sides of the tank. Then some Rattlers discovered a ladder about 30 feet from
the tank (where it had been moved in the morning when the faucet was stopped up and the
valve turned off). There was rejoicing over this discovery. Immediately some of the Rattlers
brought the ladder to the side of the tank and climbed to the top, followed by the Eagles. The
boys took turns taking off the lid to inspect the inside of the tank (see [p. 163] picture in this
chapter). There were several exclamations that the tank was three-fourths full.
The discovery of a practically full tank turned attention of both groups to the faucet again. In
investigating the outlet, Mills (R leader) found the sack stuffed in the faucet. Almost all the boys
gathered around the faucet to try to clear it. Suggestions from members of both groups
concerning effective ways to do it were thrown in from all sides simultaneously with actual
efforts at the work itself. Especially Craig (E) gave continual advice to whoever was trying to get
the material out, no matter which group that boy belonged to.
In the actual extraction of the sack, various improvised tools (knives) belonging to different
individuals were used. Mills worked for a time; Clark (E) was one of the first to work, making
suggestions at the same time. First one and then another boy tried to get the sacking out:
Simpson (R), Clark (E), Mills (R), McGraw (E), Brown (R), Mason (E), Allen (R), Swift (R) all
taking turns. The work on the faucet lasted over 45 minutes, during the first 30 minutes being
the focus of interest for most members of both groups. During this first period, there were
continually from 15 to 19 boys standing in a tight bunch watching the work. A few drops of
water aroused enthusiasm, but completion of the task was not in view. Interest started lagging
toward the end. At this point Everett (R) suggested that the Eagle participant observer (calling
him by his first name) was a big guy, and how about letting him try it. (This same Everett had
been very vociferous in denouncing this same Eagle staff member when he had come near the
Rattler cabin on some occasion.) Everett's suggestion was taken up by other boys, and the
staff took over, eventually completing the job with the use of wrenches.
When the water finally came through, there was common rejoicing. The Rattlers did not object
to having the Eagles get ahead of them when they all got a drink, since the Eagles did not have
can teens with them and were thirstier. No protests or "Ladies first" type of remarks were made.
When the first enthusiasm for the work on clearing the faucet had died down, individual drifting
away from the faucet increased. Among these boys there was a noticeable increase of mingling
across group lines in such activities as catching lizards and making [p. 164] wooden whistles.
This good-natured mingling in several spontaneous activities took place within the framework of
the common deprivation and of the interdependence that arose as a consequence of the
immediate concern of everyone. This was the first striking instance in which we observed
friendly interaction among members of the two groups on a general scale. For example, during
the work, Everett (R) offered the use of his knife. Craig (E) told him that if it worked he would
shake hands with him for supplying the tool that did the job.
After the Eagle staff member took over work on the faucet, staff called attention to the fact that
there should be a valve leading to the main water pipe, which might be the cause of the water
shortage at camp. Some of the Rattlers went to that side of the tank and removed the boulders,
then turned on the valve. Subsequently there were contradictory claims as to who discovered
the valve.
It cannot be said that the negative attitudes toward the out-groups, the standardized
unfavorable stereotypes were disappearing as a consequence of the introduction of this single
superordinate goal of high appeal value, even though there was cooperation and friendly
mingling at the time of the activities related to it. The carry-over effects of the negative
intergroup attitudes were observed at supper that very evening, and on subsequent occasions
as well.
At supper time the procedure was followed again of having both groups wait for a short time
before the meal while the staff members withdrew from the contact area. When announcement
was made for the groups to enter, the Eagles went in first, and this time the Rattlers expressed
the insinuation: "Ladies first." During the meal, members of both groups started throwing
leftovers, bottle caps, and paper. Thus they did live up to the public announcement which they
made to each other when leaving the mess hall after lunch that they would resume the
"garbage fight," as the Eagles called it. At this supper, throwing of objects started in a rather
good-natured way, but, in time, took on serious proportions. The throwing continued and had to
be stopped.
On the way to breakfast the following morning, the Rattlers saw the Eagles coming and made
several derisive comments. Barton (R) remarked that the Eagles had gone in the mess hall [p.
165] first the last time. When they got close to the front of the mess hall, Simpson (high status
R) said "Howdy," and was answered by several Eagles. The same procedure was followed of
having both groups wait for a time while staff members kept away. The Eagle entered first
again. While in line the Rattlers started singing the Caisson Song and were joined by several
Eagles. As the boys started putting food on their trays, the cook (who had no special authority
in their eyes) asked for their attention. She told them that throwing things at each other during
meals made such a mess and cleaning up was taking so much time that she would not be able
to cook such good meals if it did not stop. This appeal was effective. During breakfast there
was some horseplay and intermingling between groups. Someone started to throw something
and McGraw (E) said, "Remember, you guys, no throwing." The groups parted peacefully after
the meal.
In spite of the cessation of "garbage fights" there was tangible evidence of negative intergroup
attitudes when the Rattlers were told before lunch that there was a possibility of going to a nice
lake 60 miles away for an overnight camp-out. The Rattlers showed general enthusiasm until
Mills (R leader) asked, "Are those damn Eagles going?" Another Rattler added, "I'm not going if
they go."
Similarly, when the Eagles were told of the possibility of getting a movie to show, Craig said,
"Do we have to do it with the Rattlers?" Later he said, "We want to do some things by
ourselves." On the other hand, other Eagles indicated that they had no serious objection if the
Rattlers were in on the movie too.
The Problem of Securing a Movie: The next superordinate goal to be introduced was a feature-
length movie which has been a favorite for boys of this age level. Two films had been chosen
after consulting experts on films and brought to camp along with other stimulus materials. The
plan was to ascertain the appeal value of the film for the boys and then to make securing it
(supposedly from the neighboring town) dependent on both groups contributing a sum of
money which would appear rather prohibitive for one group to contribute alone.
In the afternoon, the boys were called together and the staff suggested the possibility of
securing either "Treasure Island" or "Kidnapped": Both groups yelled approval of these films.
After [p. 166] some discussion, one Rattler said, "Everyone that wants Treasure Island raise
their hands." The majority of members in both groups gave enthusiastic approval to "Treasure
Island" even though a few dissensions were expressed to this choice.
Then the staff announced that securing the film would cost $15 and the camp could not pay the
whole sum. Members of both groups began to make all kinds of suggestions. Mills (R leader)
jumped out between the two groups and suggested $5 each from the camp, Rattlers, and
Eagles. Myers (E) said the camp should pay $5, the Rattlers $10, and the Eagles nothing.
Harrison (R) suggested that the Eagles pay $15, and the camp and Rattlers nothing. Simpson
(R) suggested that the Eagles pay $5 and the Rattlers $2. Then Myers (E) proposed that each
group pay $3. 50. Mills (R) took this suggestion from Myers (E) and called for a vote. He
counted votes in both groups. The proposal was strongly supported. After this, there was
heated discussion in both groups concerning who would do the figuring for each group to find
out how much each member of the respective groups would have to pay. While the groups
were figuring this out, there was a great deal of horseplay and intermixing of the groups.
At last, each group came up with its solution. The Rattlers figured that each of the 11 Rattlers
would have to contribute 31¢. Each of the 9 Eagles would have to contribute 39¢ toward
securing the common goal. The Rattlers asked their staff members to contribute so that their
total would come to $3.50. McGraw and Myers (E's) told the Eagle staff members that they
would have to pay too, and gave the reason that the staff would get to see the movie too. Both
staff members agreed to do so. Martin read the list of contributions from the Rattlers, and
McGraw those of the Eagles.
It is worth noting that in individual terms this scheme of contribution was not equitable. But it
was an equitable solution between the two groups. The cooperation needed to secure the
movie was cooperation between groups, and it was perceived as such by individual members.
Therefore, the solution was seen as an equitable one by individual members of both groups.
At supper there were no objections to eating together. Some scuffling and play at sticking
chewing gum around occurred between members of the two groups, but it involved fewer boys
on both sides than were usually involved in such encounters. It [p. 167] looked like a fist fight
might develop between Simpson (R) and Mason (E), but their tempers cooled off.
After supper, "Treasure Island" was shown in the mess hall. Five rows of benches were placed
in the hall with an aisle in between. Both groups were waiting to enter, and were told to come
in. There was some confusion momentarily as to where to sit. When the milling about stopped,
the seating arrangement was pretty much along group lines with a few exceptions. The boys
were absorbed in the film, and there was very little conversation.
*****
In line with the main hypotheses of this stage, it was planned to have a series of situations
embodying superordinate goals. However, a serious concern arose for further planning of
superordinate goals. It became evident that in a camp situation like this one, isolated from a city
or town and from outside influences, the facilities for daily activities were by this time acquiring
decidedly routine aspects. Since the subjects had come to know the facilities afforded by the
camp and in the general surroundings, it became increasingly difficult to introduce
superordinate goals that would arouse high motivational appeal but were also inherent in the
situations. Therefore, an attempt was made during the day to secure additional transportation
facilities to take both groups to Cedar Lake, which is 60 miles southeast of the camp and
affords complete detachment from the accustomed camp facilities in many respects.
Of course, this procedure does not imply that under all circumstances and for all groups one
has to search for an isolated place to find situations embodying superordinate goals for
functionally related groups. If there are goals of sufficient strength for both groups in question,
or serious issues in which both groups are involved with high concern, these superordinate
goals can be introduced even within some neighborhood of a metropolis. But in a camp
situation which was by now familiar and with subjects of the age level in question, the
alternatives for superordinate goals were limited in number. The immediate possibilities at the
camp were fairly static, since no outside influences intervened.
[p. 168] The attempt to carry out the plan to go to Cedar Lake on the day following the showing
of "Treasure Island" failed because transportation was not secured. Therefore, instead of
introducing superordinate goals in an improvised way with items which might appear artificial to
the subjects, the day was marked by a return to in-group areas and activities.
While waiting in line for breakfast on the day following the movie, the two groups discussed and
reached an agreement that the Rattlers would go into breakfast first, and at lunch the Eagles
would be first. (Such alternation had been discussed the previous day, but no agreement
reached.) Thus the notion of "taking turns" was introduced by the boys on the intergroup level
to regulate matters of mutual concern, rather than each group rushing to be first.
The Rattler group went to their hideout to look after their boat, tent, and other equipment there
to take them back to their cabin. One of the activities they engaged in there had important
carry-over effects and significant implications in the course of intergroup interaction on the
following day when the joint overnight camp actually did materialize. Before lunch, the Rattlers
again started chopping on a big, dead pine tree which they had been trying to chop down for
two days in leisure moments. When the trunk was chopped through, the tree still did not fall.
The standing tree constituted both a challenge and a hazard (since it might crash down at some
inopportune moment). The boys discussed how to get it down. One suggested that they had
beaten the Eagles at Tug-of-War, so let's have a Tug-of-War against the tree. The tug-rope
was tied to the tree, and they all pulled the tree down - to everyone's great satisfaction. Thus, a
means once used in conflict with the out-group was now employed to defeat a stubborn and
hazardous tree.
In the meantime, the staff was planning the overnight camp at Cedar Lake, both its introduction
to the groups and its execution. Both groups were asked to name their preferred activities for
the remaining three days of camp, with the promise that as many as possible would be carried
out. The selection of activities was discussed in the two groups separately. Camping out was
on the list of preferred activities prepared by both groups. During the two previous days, the
staff had been dropping descriptions of the Cedar Lake site, 14 miles south of Heavener, [p.
169] Oklahoma. Objectively that site is an attractive spot -- a clearwater lake surrounded by
wooded hills, picnic facilities on high flat ground with tall shady trees, a fresh water pump
centrally located. The greatest advantage this site afforded was that there were practically no
people visiting there. It looked as though it were an abandoned island. This isolation, as well as
other characteristics of the site, were carefully checked beforehand on two trips to the site by
different staff members.
The "build-up" of the Cedar Lake site to the subjects became almost superfluous. While the
Eagle participant observer was trying to describe it, the boys had decided they wanted to go
there, even before he finished. One of the attractions for them was riding there in a truck. When
the fact was mentioned that Cedar Lake was only about 30 miles from Arkansas, the immediate
response was "Maybe we could go to Arkansas." This desire spread among the members of
both groups. However, Mason (E) asked in a displeased way if the Rattlers would be in on
every thing the Eagles wanted to do.
It will be recalled that the Rattlers had also raised some objections on the previous day to going
to Cedar Lake with the Eagles. Staff members in both groups assured the members that they
could have their own trucks for the trip to Cedar Lake.
Camp-out at Cedar Lake: The staff spent most of the night before the departure for Cedar Lake
on final preparation. A separate truck was parked near each cabin, and equipment for each
group was placed near their respective truck. A special point was made by staff to mix up the
tent accessories (poles, stakes, hammers) in a way that would make it impossible for either
group to erect their tent without exchanging parts with the other group. Food was chosen for
lunch in bulk form so that the problem of dividing it between groups and then of slicing it into
individual portions would arise.
Both groups were most enthusiastic about the trip. Breakfast was eaten at 6 A. M. in short
order. Especially in the case of the Rattlers enthusiasm was so great that their insistence on an
early start acquired nuisance proportions for the staff. They had voluntarily loaded and packed
the truck before breakfast, the truck being floored with mattresses, with bedrolls around the [p.
170] sides to lean on. The trucks pulled out around 7 o'clock, the Rattlers' shortly after the
Eagles'. Except for intervals of rest, the boys sang their preferred songs during most of the trip.
On arrival at Cedar Lake each group was taken first to a level place over the concrete dock by
the lake. The swimming place was about one-fifth of a mile from the main camping area and
separated from it by a little valley and trees so that it was not visible. When the Rattlers arrived
the Eagles were already in the water. The Rattlers went in the water also. There was about a
half-hour overlap when both groups were in the water together. There was some intermingling
between groups, but most conversation was directed to fellow group members.
While both groups were swimming, the trucks moved to the main camp area. The gear, tents,
etc. were dumped in two piles about 50-60 yards apart, the water pump being approximately
half-way between the Eagle pile and the Rattler pile. Beside each pile of belongings there were
separate picnic tables and fireplaces, in case the Eagles and Rattlers chose to have their meals
separately. Only one truck was left at this main camp area, and this was the older-looking of the
two. The tug-of-war rope was thrown on the ground about 20 feet from the truck, which was
parked at a central point. The newer truck and a station wagon were removed and hidden
behind trees on side paths away from the main camping area. The food was left in the station
wagon; however eating utensils (paper plates, cups, flatware) and jars of pickles and mustard
were stacked on a table centrally located and near the lake.
After swimming, the counselor of each group took his group to its respective tent and picnic
table location. The boys were getting hungry after the early breakfast, trip, and swim. Members
of both groups went to inspect the centrally located table on which utensils and accessories
were piled. This set the stage for the introduction of a superordinate goal.
Tug-of-War against the Truck: The staff member who drove the truck announced, so that
everyone could hear, that he would go down the road a piece to get the food. Both groups
(about 15 yards apart now) watched with interest as the driver got into the truck. The driver
struggled and perspired, the truck made all [p. 171] sorts of noises, but it just would not start
(as planned). The boys became more and more interested. Several Rattlers suggested, "Let's
push it," but they abandoned the idea because the truck was parked facing up-hill. The tug-of-
war rope was in plain sight of both groups. Mills (R) said, "Let's get 'our' tug-of-war rope and
have a tug-of-war against the truck." Someone said, "Yeah, we can't push it." Swift (R) said,
"20 of us can." Several boys agreed loudly with this, Mills adding, "20 of us can pull it for sure."
The idea of having a tug-of-war against the truck was repeated by several boys in both groups.
Mills (R) ran over to get the rope and started to tie it to the front bumper of the truck. An Eagle
said it would be too long, and suggested pulling it halfway through the bumper, thus making 2
pulling ropes. Clark (E) fed it through the bumper while Mills (R) stretched it out. Harrison (R)
suggested that the Eagles pull one rope and the Rattlers the other. Barton (R) said, "It doesn't
make any difference."
The line-up pulling on the two ends of the rope was Eagles on one side and Rattlers on the
other, with the exception that Swift (big R) joined the Eagle side as anchor-man and Craig (E)
was next to Brown (R), the anchor-man on the Rattler side.
The first pull did not "start" the truck, and it was allowed to roll back down the hill for another
pull. (The truck was, of course in running order, but the performance was completely
convincing.) On the second pull, the members of both groups were thoroughly intermixed on
both ropes. Some members of both groups began chanting "Heave, heave" in rhythm,
something the Eagles had started during the tug-of-wars in Stage 2. Finally the truck started,
and the boys all jumped and cheered. Allen (R) shouted: "We won the tug-of-war against the
truck!" Bryan (E) repeated, "Yeah! We won the tug-of-war against the truck." This cry was
echoed with satisfaction by others from both groups.
Immediately following this success, there was much intermingling of groups, friendly talk, and
backslapping. Four boys went to the pump and pumped water for each other: Mills (R), Hill (R),
Craig (E), and Bryan (E). Thus the successful, interdependent efforts of both groups in pulling
the truck, which was to get their food, had an immediate effect similar to that of superordinate
goals introduced on previous days at the camp - intermingling of members of the two groups
and friendly interaction between them.
[p. 172] Separate vs. Integrated Meal Preparation: The driver went to get the food in the truck.
While waiting for it to arrive, the participant observer of each group brought up the problem of
whether his group wanted to alternate preparing meals with the other group or prepare them
separately for themselves. In the Rattler group, Mills (leader) suggested that the Rattlers
prepare one meal that day and the Eagles the other. This was discussed at some length and
agreed upon by the Rattlers. There were no derisive comments about the Eagles during this
discussion, and no objections made to eating with them, although prior to the trip, several
Rattlers had objected to the idea of coming to the same place the Eagles were.
The discussion on this topic in the Eagle group took a different turn: At the outset, Craig and
McGraw objected to an alternating arrangement in preparing meals, saying they wanted to cook
for themselves. Low status Eagles (Clark, Cutler, Lane) were in favor of alternating with the
Rattlers. After some discussion the decision was crystallized by Mason (E leader) who stated
his opposition to alternating food preparation, and other high status members supported his
position, one after another.
These discussions and the decisions reached are particularly enlightening in view of what
actually took place immediately thereafter. The lunch materials had been selected so that if the
groups decided to eat separately, they would have to divide the ingredients before doing so.
For example, the main item was an 8 pound can of uncut luncheon meat. These situational
factors, including the location of the food, took the upper hand in determining how the meal
would be prepared. Here curtailment of effort involved in division of the supplies became
dominant.
When the truck arrived with the food, both groups rushed from their respective camp areas and
started carrying the food to the centrally located picnic table. At the table, they gathered around
discussing across group lines whether they would alternate in meal preparation, the Rattlers
favoring it and the Eagles opposing it. But in the midst of this discussion, food preparation
together actually began. McGraw, the customary meat-cutter in the Eagle group, began cutting
the meat. He received much advice from everyone, and Mills (R) stood at his elbow for a time
and helped him. In the meantime, Simpson (R) and Craig (E) poured Kool Aid into a bucket,
Harrison (R) went for water to [p. 173] mix it, and Myers (E) poured in what he thought was
sugar. Unfortunately, it turned out to be salt; but Myers was not berated by either Eagles or
Rattlers for his mistake, even though the only immediately available Kool Aid was ruined.
Harrison (R) pointed out that it wasn't really Myers' fault since the salt was in a sugar sack. Low
status members on both sides were particularly active after this in preparing and distributing
food. At one point, Mason (E leader) and Simpson (R) were talking and Simpson said, "You
never thought we'd be eating together?" The reply was laughter. (See pictures.)
The first Eagles through the line went to a centrally located picnic shed nearby and sat down at
the tables. The first five or six Rattlers went to tables near their own camp area. Allen (R) asked
a staff member where he should sit, and was told to sit any place he wanted. He then went to
the shed and sat down with the Eagles. Neither at this time nor later was he criticized for his
action. After eating, Mills (R) and Barton (R) also drifted over to the Eagle table for a short time.
Shortly both groups went to their respective camp areas for a rest period.
After separate rests, the two groups were taken to swim, one shortly after the other. This time
the Rattlers were in first, but got out of the water on seeing a water moccasin darting about.
When the Eagles arrived, the Rattlers told them in excited tones of a snake moving around in
the vicinity, describing it in detail. For about 15 minutes, all of the boys stood together at the
pier and discussed this common threat coming from nature. Then they swam together at
another spot for a short period, both groups mixing together in the water.
Tent-pitching: At about 4 o'clock in the afternoon, after the swim, another superordinate goal
was introduced. It will be remembered that in packing the tents, the accessories were mixed so
that for either group to erect a tent, some exchange of parts would be necessary. Now when
each group prepared to erect their tents for the night, each noticed right away that they did not
have all the complete and necessary accessories. The staff member who was regarded by the
boys as the camp authority was standing between the two camp areas. The two groups started
toward him carrying extra parts and arrived in front of him at about the same time. Members of
the two groups began telling [p. 174] each other what extra parts they had, and what was
needed. After exchanging very few words, the trading of necessary items was accomplished in
a matter-of-fact way between the two groups - the perceptual situation was so compelling.
When the Rattlers started to erect their tent, they found they had neglected to get a stake-
driving mallet in the trade. They used rocks instead, with staff assistance, finishing the job by
themselves. They were aware throughout of the Eagles' progress in tent-pitching and felt quite
satisfied when their own tent was up first, since the Eagles had won the tent-pitching contest in
Stage 2. Someone commented that they had won this time even using rocks; and another
Rattler suggested that maybe they should have used rocks for driving stakes in the contest.
The Eagles were also aware of the Rattlers' progress; but since they were having a hard time
putting their tent up on uneven ground, they did not try to compete with the Rattlers.
The Truck Stalls Again: Before supper, the truck going to get food stalled again, as planned.
This time, discussion was practically unnecessary. The pattern for cooperation was established.
The first effort, initiated by Rattlers, was to push the truck (see picture). When the truck rolled
into a hanging tree limb, Mills (R) got the tug-of-war rope again. The rope was pulled through
the bumper, and two bunches of boys lined up to pull. However, these two lines on each side
were not the Eagle and Rattler groups. Members of both groups were thoroughly mixed
together in the pulling, which was accompanied by concerted rhythmic chants of "Heave,
heave."
Again there was pride in the joint accomplishment. Thus the same tool which had served first in
a competitive situation during group conflict, and which was later used by one group in their
efforts to fell a tree, now became the standard means for interdependent efforts by both groups
toward a common, superordinate goal (starting the truck which brought food for all).
This sequence probably points to the fact that the nature of intergroup relations - for good or
evil - does not necessarily stem from the existence of tools and techniques: the same tools and
techniques can be used in the service of harmony and integration as well as in the service of
deadly competition and conflict.
[p. 175] As soon as the boys saw the truck returning with food, they rushed to the table where
food was served at noon. This time the main dish was steak-meat in a big chunk, and the
necessary division of labor was more elaborate. However, the cooperative pattern was now
established and there was no appreciable discussion of it. As soon as the truck was unloaded,
in which the boys helped both groups began to work at preparing supper. There was much
intermingling - Rattlers and Eagles working side by side, taking suggestions from each other,
and reaching decisions about what to do together. For example, McGraw (E) told three Rattlers
to "Come on, boys, and put that Kool Aid in there," and they did. Simpson (R), Hill (R), and
McGraw (E) all tried their hand in the initial stage of cutting steaks off the big chunk of meat.
McGraw (E), Simpson (R), and Wilson (E) declared that they were going to cook.
After these boys declared their intention to cut meat and cook, staff members stepped in to give
effective assistance in getting the meat cut and the steaks broiled. Other Eagles and Rattlers
worked together in setting out utensils and other food. After the preliminary preparations, those
boys who were not helping rushed to pick up paper plates and to form a line by the fire, in
which no one gave a moment's thought of preserving arrangements in terms of group lines.
All of the boys ate under the shed where the Eagles had eaten lunch. Eagles and Rattlers were
interspersed up and down the table on both sides. There was considerable changing and
shifting back and forth in the seating arrangements throughout the meal.
After supper a good-natured water fight started at the edge of the lake, but the throwing and
splashing was not along group lines. The leading parties on one side were Simpson (R), Mason
(E), and Swift (R), while those leading the other side were Mills (R) and Brown (R). The boys
engaged in this until they were soaking wet, then dried out by the fire. Rain clouds came up
over the hill with a strong wind. The boys retired for the night to their respective group areas.
The Trip to the Border: The following morning (Day 6, Stage 3), the Rattlers awoke first and
started talking about the [p. 176] trip to Arkansas, exchanging notes on the states they had
visited. The Rattlers attention was concentrated on the Eagle camp. Martin (R) asked if the
Eagles were going to Arkansas too. When the counsellor answered affirmatively, there was no
objection or comment. Simpson, Newman, Harrison, and Alien (all R's) went to the Eagle camp
to see the lizards Mason (E) had caught and frogs that Cutler (E) and Clark (E) had collected.
The Rattlers were anxious to start on the trip to Arkansas before breakfast, and they kept
getting in and out of their truck, which they had loaded even before breakfast. A short time later
both groups were asked to come to a central location for an announcement.
It was announced that, as they well knew from experiences of the previous day, the older truck
was not in good shape for the trip to Arkansas and back to the camp. (The truck referred to
happened to be the Eagle truck. Of course it was in running condition. But it had been
demonstrated to be liable to break down on the previous day as a part of the plans for
producing problem situations embodying superordinate goals. This build-up of a poor reputation
for the truck was also appropriate for the introduction of the problem situation now being
described.) It was added that in view of the condition of the truck, it might be preferable to give
up the idea of going to Arkansas, since there was only one truck. General disappointment was
voiced, especially by the Eagles.
McGraw (E) suggested that the Rattlers go to Arkansas first, and then that the Eagles would go
in the Rattler truck when they returned. But Craig (E) objected that the Eagles didn't want to
wait around all morning; and when Mason (erstwhile E leader) started chanting "Let's go home,
Let's go home..." (meaning camp), Craig joined him.
At one point, Clark (E) said, "We could all go together" but Simpson (R) said, "No" - that the
Rattlers would go to Arkansas and the Eagles could go back to the camp. This discussion
illustrates well the state of flux which prevailed at this time in intergroup affairs. At times, as at
supper the previous evening, the group lines seemed to disappear; at others the group
demarcations would re-appear. Whether or not group lines would be followed was coming to
depend more and more on factors in the immediate situation (situational factors).
[p. 177] In this instance, the problem at hand was discussed for a short time. Then Mills (R
leader) proposed that they all go in the Rattler truck: "We can move some of the mattresses
into the other truck, and then we can all get in our truck." Allen (low status R) repeated this
suggestion and several Eagles expressed approval. Simpson (R) agreed that would be
possible, but added, "Let's don't."
Mills (R) now moved out of his group and paced up and down between the groups, explaining
his ideas to both of them. When staff asked what they were going to do, there was a general
hub-bub which was resolved when Mills (R) and Clark (E) said "Let's go!" and headed for the
Rattler truck. All the other boys, both Rattlers and Eagles, ran after them, piled in the truck, and
yelled out to staff to "Hurry up!", "Let' s go!" This is another striking instance of action taking
precedence over verbal discussion, although the latter played an important part even in this
decision.
While both groups were in the Rattler truck waiting to pull out, the Rattlers asked the Eagles to
tell them who got homesick and went home from their group. Then as the truck started out on
the trip, notes and memories were exchanged concerning the raids which had aroused so much
indignation during Stage 2. Now there was mirth over some of the episodes, and some
bragging over who did what. Shortly, Clark (E) began to whistle the Star Spangled Banner and
was joined by several boys. Boys from both groups joined and shortly everyone was singing.
Without any discussion, the members of both groups now continued signing for about half-an-
hour, alternating a song which had become associated with the Eagles with one which the
Rattlers had adopted. No one suggested that the songs of the two groups be alternated, but in
fact they were. The arrangement of "taking turns" at an intergroup level was being extended
from one activity to others.
The truck stopped in Heavener, Oklahoma to allow the boys to have cool drinks. They
streamed out of the truck into a drugstore; and the seating arrangements at the tables, which
seated four or five boys each, reflected little of the group demarcations.
Back in the truck and onto the highway, the Arkansas line was reached, but the road had
turned from a hard-surfaced highway to a dirt road. Conversation died down during this dusty
[p. 178] portion of the trip. When the truck finally arrived at the prearranged lunch stop, the boys
felt they had "been through" something together: the fine dust was deposited over everything
and everyone.
Lunch was eaten in a private dining room, secured at a restaurant, amid much laughter and
boisterous conversation. Members from both groups were thoroughly intermixed at the four
tables. After second servings, a paper and pencil were placed on each table, and the boys were
told to list the flavors of ice cream they wanted. Then they were told to combine the lists at a
side table. Myers (E) and Martin (R) both volunteered to do this. Myers was closest to the table,
and therefore was able to get the pencil and paper first. But boys from both groups intervened,
insisting that Myers and Martin work up the combined list together, which they did.
After lunch most of the boys wrote postcards to send home as evidence that they had been in
Arkansas. Then the trip continued back to the Arkansas line, which had been crossed in the
morning but not noted because there was no marker and the road was so dusty.
At a coke stop near Fort Smith, Craig (E) and Allen (R) suggested that when the camp was
over everyone should return to Oklahoma City together on the same bus. This idea was
approved by most boys in both groups, although some said nothing and Harrison (R) muttered,
"Let's go back like we came." Mills (R leader) said nothing until it was evident that the majority
supported the idea, then he backed it too.
When the truck arrived at the state line between Arkansas and Oklahoma, the boys got out of
the truck and most of them posed to have their pictures taken. Many of them stood straddling
the state line so they could tell their family and friends that they had been in two states at the
same time when they returned home (see picture).
During the entire trip from Cedar Lake into Arkansas and back across the line into Oklahoma,
there were very few signs of group demarcations or identifications. However, when the truck
arrived at camp and the Eagles were dropped off at their cabin, the Rattlers started yelling
"Goodbye, Eagles", and the Eagles reciprocated.
[p. 179] The Last Evening in Camp: In order to check the influence of situational factors at this
rather fluid state of intergroup relations, the staff re-arranged the camp dining room while the
two groups were at their cabins cleaning up from the trip. Four tables smaller than the usual
mess hall tables were brought from various parts of the camp. They were square and could
conveniently seat eight people, two to a side. This change was made that the habitual spacing
and size of tables in the mess hall situation would be entirely different. The influence of
situational factors has been noted previously. It was thought that if the mess hall situation were
different than it had been previously, the present state of relationship between the two groups
would be revealed more clearly through a new seating arrangement.
The wisdom of this plan was confirmed even outside of the mess hall. There the two groups
formed two lines, just as they had done prior to the Cedar Lake camp-out, even though they
had been mixing up at meals as well as in other situations during the past 24 hours. The groups
began discussing who would go in first the trip away from camp having upset their "taking
turns" arrangement. There was discussion on both sides as to whose "turn" it was. When
Simpson (R) finally said, "O.K., let them go ahead", the Eagles entered the mess hall first
without further objections by the Rattlers.
Once inside the two groups went through the line to get their food separately, but there was
friendly conversation between members of the two groups. The reactions to the new table
arrangement were as anticipated. In spite of the fact that the groups had lined up separately in
habitual fashion to get food, the seating at the newly arranged tables cut across the in-group
demarcations. The two tables in the middle were occupied by Eagles and Rattlers sitting
together. The few Rattlers left over occupied one or the other of the two end tables.
During the meal several boys commented that everyone was going back to Oklahoma City on
the same bus. Almost all the boys seemed to be planning on it, although one voice was heard
to say, "No, we're not " There was even some talk about what they would do on the bus.
After supper the boys were asked what they wanted to do on their last night at camp. There
were several suggestions, including a Rattler's that they all go to the Stone Corral. The Rattlers
[p. 180] backed this idea strongly, since the Stone Corral was the site of their campfires, and
was considered "theirs." Wilson (E) wanted to go to Robbers Cave, and most of the Eagles
backed this idea. But the Rattlers replied that the Stone Corral was a part of Robbers Cave,
and they couldn't build a fire at the Cave itself. The discussion ended when Mills (R)
announced they would all meet in five minutes to go to the Stone Corral. The Eagles said they
would meet at the mess hall, but Mills (R) kept insisting that they should meet at the Rattlers'
cabin, because this was closer to the Stone Corral. The groups parted with that understanding.
When the Eagles arrived at the Rattler cabin, both groups went together to the Stone Corral.
Simpson (R) took his ukulele with him and began to play as soon as they arrived. Everyone
began singing the favorite songs of both groups, then it started to rain. The boys scattered to
find cover. Some of them continued singing until the rain stopped and the campfire could be
built. While waiting for the fire, a Rattler suggested that the two groups entertain each other by
putting on the skits they had done for the tournament. Two or three boys thought this was a
good idea, but nothing came of it until after both groups joined in roasting marshmellows.
Then Mills (R leader) started organizing the "Dragnet" skit which he had put on with several
other Rattlers before his own group earlier in camp. Myers and Craig, both Eagles, were asked
to help the Rattlers put the skit on. Some of the Eagles called to Myers (E), and he answered
that he would be in the Eagle skit too.
After the Rattler skit, Mills (R) announced that the Eagles were next. There was some
discussion on what to do, then Wilson and Myers put on an act for the Eagles. The Rattlers
next started trying to persuade Brown to do his "Donald Duck" imitation. This performance was
received with great enthusiasm. Then Allen (R) said, "Now it's the Eagles' turn," and the Eagles
did a "spitball act."
At this point the Eagles wanted the Rattlers to be next on the evening's program; but the
Rattlers replied that since the Eagles had won the singing during the tournament, they should
sing for them now. After some discussion, Myers (E) announced that Simpson (R) would sing a
song, which he did. Then the Eagles [p. 181] took their turn, singing "Zem Bones" (actually
"Dem Bones").
Following this request performance by the Eagles, Mills (R) announced that the Rattlers would
do a skit called "Murder in the Haunted House." The evening ended with both groups singing
together some of their favorite songs (see pictures).
Up to the time of this joint campfire at the Stone Corral, the observations had revealed
increasing reduction of intergroup friction and increasingly friendly relations between the groups
as a consequence of interdependent activities embodying superordinate goals which were
experimentally introduced. The Eagle observer noted that derogatory references to the out-
groups had decreased gradually, until there were none.
However, the evening campfire was a striking demonstration of the cumulative effectiveness of
situations requiring interdependent activities toward common superordinate goals. Procedures
for cooperative give-and-take between groups had been developed. The entire program was
arranged and presented by the two groups themselves to entertain each other. The notion of
"taking turns", which had started as a way of regulating activities in which a conflict of interests
was involved (going in to meals), had been extended to joint singing of the two groups' favorite
songs on previous occasions. Now the "taking turns" idea was spontaneously used to regulate
group participation in entertaining one another, as groups and as individuals. Thus the
establishment of friendly relations between groups through functional interdependence in
situations involving experimentally introduced goals was carried over (transferred) to
spontaneous intergroup cooperation in a situation in which no superordinate goal was formally
introduced.
During the following day, which was the last day of camp, no planned stimulus conditions were
introduced. It was designated as "follow-up" day. Observations were restricted to striking
instances of the interaction patterns and carry-over effects of the experimentally introduced
conditions. At breakfast and lunch the last day of camp, the seating arrangements were again
mixed up insofar as group membership was concerned. The morning was devoted to
preparations for leaving camp and to securing checks on observational findings through
sociometric choices and stereotype ratings. The results of these units are reported in the
following parts of this chapter.
[p. 182] The Trip Home: The majority of subjects had agreed by the last day that it would be a
good thing to return to Oklahoma City all together on one bus. When they asked if this might be
done and received an affirmative answer from the staff, some of them actually cheered. When
the bus pulled out, the seating arrangement did not follow group lines. Many boys looked back
at the camp, and Wilson (E) cried because camp was over.
Just before the bus pulled into the town where a refreshment stop was planned, a Rattler
inquired if they still had the five dollar reward they had won in the bean toss contest. This
inquiry was repeated by others when the boys were at the refreshment stand, and Mills (R
leader) suggested that their five dollars be spent on malts for all the boys in both groups.
Several Rattlers nearby agreed; the others approved the idea when asked. This meant that
malted milks for all 20 boys would be paid for exactly with the five dollars contributed by the
Rattlers, but that each boy would have to pay for sandwiches and other treats himself.
Several Rattlers were questioned by observers while they were eating, and they were all fully
aware that this sum would have paid for everything the Rattlers wanted if it had not been
shared with the Eagles. Nevertheless, they were glad they had shared it. A few boys were short
of money for other refreshments and other boys (several from the out-group) paid for them.
Nearing Oklahoma City, the boys at the front of the bus (mostly high status members from both
groups) began to sing "Oklahoma." Several boys seated near the back rushed up to join them.
Everyone in both groups took part, all sitting or standing as close together as possible in the
front end of the bus. The gaiety lasted during the last half hour of the trip; no one went back to
the rear. A few boys exchanged addresses, and many told their closest companions that they
would meet again.
At the bus station, goodbyes blended with the excitement of meeting parents.
Summary of Observations in Stage 3
On the basis of the above observations reported by participant observers and independent
observations by other staff members, it can be concluded that:
[p. 183] When groups in a state of friction are brought into contact under conditions
embodying superordinate goals the attainment of which is compelling but which
cannot be achieved by the efforts of one group alone, they cooperate toward the
common goal.
On the basis of the above observational data it can also be concluded that:
Cooperation between groups necessitated by a series of situations embodying
superordinate goals will have a cumulative effect in the direction of reduction of
existing tension between groups.
Thus, our hypotheses 2 and 2a (Stage 3) are confirmed. In the following parts of this chapter
the validity of the above conclusions based on observational findings will be tested in terms of
sociometric choices and also in terms of laboratory-type judgmental indices.
Verification of Observational Findings Revealing Reduction of Intergroup Friction
Evidence of reduced intergroup friction and increasingly cooperative relations during the closing
days of Stage 3 was dramatic to those who had witnessed the hectic days of intergroup conflict
in Stage 2 and the early contact situations without superordinate goals early in Stage 3. The
intermingling among members of the previously antagonistic groups at meals, campfires and at
play; their joint efforts at tasks and entertainment during the camp-out and on the return to
camp; their preference to return home together - all of these and other observational data
indicated unmistakable shifts in attitudes toward the out-group. If these observed alterations in
behavior of the two groups in a variety of interaction situations were in fact indicative of
changed attitudes toward the out-group, they would be revealed as well through more precise
methods for assessing attitudes of individual members.
Accordingly, at the end of Stage 3 attitudes toward in-group and out-group were tapped, as a
further check on observational [p. 184] data, through:
1. sociometric choices of in-group and out-group members, and
2. ratings of in-group and out-group in terms of the stereotypes actually used during the period
of intergroup friction.
The results of both measurements could be evaluated in relation to (a) observational findings of
Stage 3, and (b) the results obtained by these same methods at the end of Stage 2 when in-
group solidarity and glorification, and out-group avoidance and derogation were at their height.
In line with the chief methodological concern of this experiment, findings throughout were
checked by as many different methods as it was feasible to introduce without destroying the
dominant trend of the on-going interaction processes. We sought to achieve the combination of
methods which are frequently (though erroneously) viewed as antithetical: observation of the
natural flow of interaction processes in life-like situations and more precise measurement of the
effects of interaction on the perception and judgment of individual members through laboratory-
like methods.
The interaction situations are "life-like" because they embody valued goals and appear to
subjects as spontaneous and natural, even though they are controlled and systematically
altered by experimenters. The techniques used for verification of observational data are
"laboratory-like" because they are introduced with little of the artificiality of the laboratory, but
with no loss in precision. When it has been necessary, we have sacrificed precision rather than
cluttering or unduly interrupting the interaction process, with the conviction that the flow, events,
and effects of interaction within and between groups are the basic data which cannot be easily
restored if trifled with. Sociometric choices were not obtained at the end of Stage i, but only at
the close of Stages 2 and 3 on the grounds that three repetitions within such a short time might
very well arouse the subjects' suspicions. Similarly, the experimental unit tapping attitudes
toward in-group and out-group members through judgments of their performance executed at
the end of Stage 2 was not repeated in Stage 3 because of the serious concern that its
repetition would clutter the main flow of the interaction process at that time.
[p. 185] The results of the two techniques employed at the end of Stage 3 to check the validity
of observational findings are summarized in the following two sections.
2. Verification of Shifts in Attitudes Toward In-group and Out-group Through
Sociometric Choices
At the end of Stage 3, sociometric choices were obtained by participant observers through
informal interviews with individual members of their group (see Chapter 6). Sociometric scores
were again computed for each group member on the basis of total weighted choices on four
criteria (see Chapter 6). Since the most general criterion permitted out-group choices as well as
in-group choices, total scores were computed separately for in-group and out-group choices
and also by combining in-group and out-group choices (the latter had been insignificant at the
end of Stage 2). The ranks within each group were the same by either method of computing
total sociometric scores (viz., including out-group choices or not including them).
Table 1 compares the ranks of members of each group in terms of sociometric scores with the
status ratings by participant observers of each group. The rank order correlations for status
ranking by the two methods are high and significant for both groups.

[p. 186] For purposes of comparison with data at the end of Stage 2, the members of the
Rattler and Eagle groups are listed below in terms of rank of sociometric score at the end of
Stage 3. The list of boys in each group is divided in terms of score values. Those boys in the
top level of the list received scores above 50; those in the second section 40-50; in the third
section 20-30; and in the bottom section below 20 (see Sociograms, Chapter 6).

In line with the hypothesis stated in general form in Stage 2, it was predicted that shifts in in-
group relationships might occur concomitant with changes of consequence in relations between
groups. The most significant of these (according to sociometric indices) is Mason's slip from the
leadership position in the Eagles. As elaborated in Chapter 6, Mason came to the leadership
position in the Eagle group in the early days of intergroup competition and rivalry in the
tournament. He was intensely involved with the group effort to win and identified with its victory.
It was Mason who took the lead in attempting retaliation on the Rattlers for their last raid.
Perhaps this partially explains why Mason resisted the trend in his group toward increased
intermingling with the Rattlers near the end of Stage 3. While he became quite friendly with
individual Rattlers, he made it known that he preferred that the Eagles do things together and
without the Rattlers. Although his status in the Eagle group remained high, he was followed
less and less in his separatist preferences.
[p. 187] In-group and out-group choices: The data obtained from the most general criterion on
the sociometric questionnaire, and through an item on the questionnaire tapping rejections
(dislike), provide clear-cut verification of changed attitudes toward the out-group as a
consequence of intergroup relationships in a series of situations embodying superordinate
goals.
Table 2 gives the choices of in-group and out-group members by Rattlers and Eagles made at
the end of Stage 3. As indicated in the table, friendship choices were still predominantly for in-
group members.

f % f %
In-group choices 63 63.6 41 76.8
Out-group choices 36 36.4 15 23.2
However when the choices of out-group members at the end of Stage 3 are compared with
those at the end of Stage 2, a substantial and significant increase is found for both groups. This
comparison is made in graphic form in the figure on the next page.
At the end of Stage 2, only 6.4 per cent of the Rattlers' choices were for Eagles; but by the end
of Stage 3, 36.4 per cent of their total friendship choices were for Eagles. In the Eagle group,
the proportion of choices for the out -group (Rattlers) shifted from 7.5 per cent at the end of
Stage 2 to 23.2 per cent [p. 188] at the end of Stage 3.
Concomitant with the increased tendency to choose out-group members as friends there was a
decreased tendency to reject members of the out-group as persons most disliked. In the Rattler
group, 75 per cent of the rejections at the end of Stage 2 were of Eagles; however by the end
of Stage 3, only 15 per cent of their rejections were of Eagles. Similarly, in the Eagle group, 95
per cent of their rejections at the end of Stage 2 were Rattlers, but the proportion of rejections
directed at out-group members decreased to 47.1 per cent at the end of Stage 3.
Table 3 compares the changes toward increased choice of out-group members from Stage 2 to
the end of Stage 3 and the changes toward decreased rejection of out-group members for both
groups.

Stage 2 and Stage 3
In the Rattler group, the increase in out-group choices from the end of Stage 2 to the end of
Stage 3 is significant at less than .001 level (McNemar test). The decrease in rejection of out-
group members from Stage 2 to the end of Stage 3 is significant at less than the .01 level. The
observational data revealed some divergence among members of the Eagle group in attitudes
toward the out-group. As might be expected, the differences between out-group choices at the
end of Stage 2 and at the end of Stage 3 were slightly less than for Rattlers and significant at
[p. 189]
[p. 190] lower levels.
These data obtained through sociometric techniques constitute, therefore, clear-cut verification
of observational findings that when the two hostile out-groups interacted repeatedly in
situations embodying goals superordinate to both, the prevailing tendency in both groups was
to intermingle with the other, to have increasingly friendly associations with out-group
members, and friendly attitudes toward them.
3. Verification of Effects of a Series of Superordinate Goals on Attitudes Toward the Out-
group Through Stereotype
Ratings
As a result of the series of situations embodying superordinate goals in Stage 3 and the
interdependent interaction between the hitherto antagonistic out-groups, the two groups
engaged in a greater variety of activities together and with increasing freedom. The
observations during Stage 3 revealed sharp decrease in the standardized name-calling and
derogation of the out-group which had become so familiar during the closing days of Stage 2
and the contact situations without superordinate goals early in Stage 3. In addition, there was
less of the blatant glorification of the in-group and bragging on its accomplishments than during
the days of rivalry in Stage 2. These observational data were believed to imply changes in
attitudes toward the out-group in a more favorable direction, weakening of negative stereotypes
of the out-group, and shifts in conception of the in-group as well.
The validity of these observational findings was checked at the end of Stage 3 through ratings
by both groups of their in-group and the out-group on the stereotypes which had been
standardized in Stage 2. It is significant that when it was announced that the ratings were to be
made again, several boys remarked that they were glad, because they had changed their
minds since the last ratings.
At the end of Stage 3, the procedures utilized for tapping stereotypes at the end of Stage 2
(intergroup friction) were repeated (see Chapter 6). The second ratings of in-group and out-
group on stereotypes which had been used by subjects during [p. 191] Stage 2 were obtained
in order to compare them with those obtained before the series of superordinate goals was
introduced in Stage 3 The comparison reveals the effects of interdependence created by
compelling goals superordinate to both groups and of the subsequent cooperation between
groups. The data to be presented here, therefore, will constitute additional evidence for the
verification of the following hypothesis:
Hypothesis 2 a, Stage 2
Cooperation between groups necessitated by a series of situations embodying
superordinate goals will have a cumulative effect in the direction of reduction of
existing tension between them.
Observational and sociometric data relevant to this hypothesis were summarized earlier in this
chapter.
Table 4 shows ratings of out-group members made by Rattlers and Eagles at the end of Stage
2 (friction) and at the end of Stage 3.

[p. 192] A comparison of these data obtained following intergroup friction and following
cooperative interaction in situations embodying superordinate goals shows a marked shift in the
nature of characteristics attributed to the out-group. At the end of the friction stage ratings of
out-group members tended to be unfavorable, but by the end of the integration stage, ratings of
out-group members were preponderantly favorable in both groups. At the end of Stage 2, 53
per cent of the ratings made by Rattlers of the Eagles had been unfavorable; but at the end of
Stage 3 only 4.5 per cent of these ratings were unfavorable and 86.3 per cent were favorable.
Most ratings of the Rattlers by the Eagles (76.9%) were unfavorable at the end of the friction
stage; but by the end of Stage 3 the proportion of unfavorable ratings was reduced to 22.6, and
the favorable ratings of Rattlers increased to 68 per cent.
The Eagles' ratings of the Rattlers did not change as much in the favorable direction from
conditions of competition to conditions of cooperative interaction as the Rattlers' ratings of the
Eagles. However, these shifts in the positive direction from Stage 2 to Stage 3 were significant
for both groups (Table 4).
Table 5 presents ratings made of members of the in-group at the end of Stage 2 (friction) and
Stage 3 (integration). These results suggest that changes in the functional relations between
groups tend to produce changes in the conceptions of the in-group.The ratings of in-group
members after cooperation with the out-group were not as favorable as the highly positive
ratings of the in-group made after the intense intergroup rivalry of Stage 2 although the trend is
not statistically significant. At the end of Stage 3, in-groups were still rated favorably by their
own members.
For the Rattler group, the difference in proportions of ratings in the most favorable category at
the end of Stage 2 and the end of Stage 3 was 9 per cent, and the proportion of ratings in the
middle category increased by 4.5 per cent. In the Eagle group, the proportion of ratings in most
favorable category after the cooperative activities with the out-group (Stage 3) was 25.9 per
cent less than at the end of Stage 2 (intergroup friction).
The trend toward rating the in-group less favorably was more pronounced in the Eagle group.
This finding is in line with

observational data indicating that the Eagle group revealed shifts in status structure, during the
interaction in cooperative activities with the Rattlers during Stage 3. Briefly, most of the Eagles
were drawn into the compelling interdependence between groups in Stage 3 and all
participated in cooperative intergroup activities. A few Eagles, including the leader during Stage
2, entered into these activities and became friendly with individual members of the Rattler
group, but were more tenacious than others in preferring in-group association to contacts with
the whole Rattler group. As noted earlier, this state of affairs, in turn, reduced the effectiveness
of the Eagle leader, who had achieved his greatest eminence during intergroup rivalry.
The accompanying figures present a graphic summary of the stereotype ratings of in-group and
out-group by the Eagles and Rattlers on the six characteristics (combined) following Stage 2
and Stage 3. At the end of Stage 3, ratings of in-group and out-group members did not differ
significantly (p .10).
[p. 194]
[p. 195] Thus, at the end of Stage 3:
(a) Favorable characteristics tended to be attributed to the out-group, in contrast to
the predominantly unfavorable picture of the outgroups the end of Stage 2 (friction).
(b) Ratings of both the in-group and the out-group were favorable and did not differ
significantly.
(c) The relative frequency of favorable ratings made in relation to in-group members
was slightly less than at the end of Stage 2 (friction), particularly in the case of the
Eagle group which was undergoing some shifts in in-group structure.
Competition and rivalry between groups in Stage 2 was accompanied by attribution of
unfavorable characteristics to the out-group and favorable characteristics to the in-group
(Chapter 6). This generalisation takes on added significance when viewed in terms of the
backgrounds, personal and socio-cultural, of the two groups of boys. All were normal, well-
adjusted boys who enjoyed high and secure status positions both at home and in school. None
were problem children who had suffered unusual frustrations and privations. The results
indicating the formation of negative stereotypes of the out-group during competitive intergroup
relationships cannot be attributed to unusual psychological conditions brought by the boys to
the experimental situation. The enthusiastic participation in intergroup competition reflects, of
course, the strong emphasis on competition in the larger socio-cultural setting. However, the
rise of intergroup hostility and attribution of derogatory labels to the out-group was a
development opposite in direction to another important value from the larger setting, namely
"good sportsmanship" on the part of participants in competitive activities.
The observance of norms of social distance between the groups and maintenance of a
derogatory picture of the out-group did not decrease until the two groups had interacted in a
series of situations embodying superordinate goals. The subsequent cooperation between the
groups was accompanied in time by a marked change in the conception of the out-group in the
favorable direction.
These results may be taken as further evidence supporting [p. 196] our hypothesis that
cooperation between groups as a consequence of interaction in situations embodying
superordinate goals has a cumulative effect in the direction of reducing existing tensions
between them (Hypothesis 2 a, Stage 3).
The data obtained by tapping judgments concerning the character of one's in-group and of the
out-group under conditions of competition and rivalry (Stage 2, see Chapter 6) and conditions
leading to cooperative intergroup activity are congruent with observational findings concerning
behavior in relation to the in-group and out-group. Together they are presented as a
contribution to the study of the formation and change of values or social norms. Specifically,
these data confirm the hypotheses concerning conditions conducive to the formation of
unfavorable attitudes toward functionally related out-groups and conditions conducive to their
change to attitudes of cooperation and friendship between groups.
[p. 197] CHAPTER 8
Summary and Conclusions
A. The Present Approach
In this book we have presented an experiment on Intergroup relations. The theoretical
approach to the problem, the definitions of groups and relations between them, the hypotheses,
the selection of subjects, the study design in successive stages, the methods and techniques,
and the conclusions to be drawn are closely related. This chapter is a summary statement of
these interrelated parts.
The word "group" in the phrase "intergroup relations" is not a superfluous label. If our claim is
the study of relations between two or more groups or the investigation of intergroup attitudes,
we have to bring into the picture the properties of the groups and the consequences of
membership for the individuals in question. Otherwise, whatever we may be studying, we are
not, properly speaking, studying intergroup problems.
Accordingly, our first concern was an adequate conception of the key word "group" and
clarification of the implications of an individual's membership in groups. A definition of the
concept improvised just for the sake of research convenience does not carry us far if we are
interested in the validity of our conclusions. The actual properties of groups which brought them
to the foreground in the study of serious human problems have to be spelled out.
The task of defining groups and intergroup relations can be carried out only through an
interdisciplinary approach. Problems pertaining to groups and their relations are not studied by
psychologists alone. They are studied on various levels of analysis by men in different social
sciences. In the extensive literature on relations within and between small groups, we found
crucial leads for a realistic conception of groups and their relations (Chapter 1).
Abstracting the recurrent properties of actual groups, we attained a definition applicable to
small groups of any description. A group is a social unit which consists of a number of
individuals who, at a given time, stand in more or less definite
[p. 198] interdependent status and role relationships with one another, and which explicitly or
implicitly possesses a set of norms or values regulating the behavior of the individual members,
at least in matters of consequence to the group.
Intergroup relations refer to relations between groups thus defined. Intergroup attitudes (such
as prejudice) and intergroup behavior (such as discriminatory practice) refer to the attitudes
and the behavior manifested by members of groups collectively or individually. The
characteristic of an intergroup attitude or an intergroup behavior is that it is related to the
individual's membership in a group. In research the relationship between a given attitude and
facts pertaining to the individual's role relative to the groups in question has to be made explicit.
Unrepresentative intergroup attitudes and behavior are, to be sure, important psychological
facts. But attitude and behavior unrepresentative of a group do not constitute the focal problem
of intergroup relations, nor are they the cases which make the study of intergroup relations
crucial in human affairs. The central problem of intergroup relations is not primarily the problem
of deviate behavior.
In shaping the reciprocal attitudes of members of two groups toward one another, the limiting
determinant is the nature of functional relations between the groups. The groups in question
may be competing to attain some goal or some vital prize so that the success of one group
necessarily means the failure of the other. One group may have claims on another group in the
way of managing, controlling or exploiting them, in the way of taking over their actual or
assumed rights or possessions. On the other hand, groups may have complementary goals,
such that each may attain its goal without hindrance to the achievement of the other and even
aiding this achievement.
Even though the nature of relations between groups is the limiting condition, various other
factors have to be brought into the picture for an adequate accounting of the resulting
intergroup trends and intergroup products (such as norms for positive or negative treatment of
the other group, stereotypes of one's own group and the other group, etc.). Among these
factors are the kind of leadership, the degree of solidarity, the kind of norms prevailing within
each group. Reciprocal intergroup appraisals [p. 199] of their relative strengths and resources,
and the intellectual level attained in assessing their worth and rights in relation to others need
special mention among these factors. The frustrations, deprivations and the gratifications in the
life histories of the individual members also have to be considered.
Theories of intergroup relations which posit single factors (such as the kind of leadership,
national character, individual frustrations) as sovereign determinants of intergroup conflict or
harmony have, at best, explained only selectively chosen cases.
Of course leadership counts in shaping intergroup behavior, the prevailing norms of social
distance count, so do the structure and practices within the groups, and so do the personal
frustrations of individual members. But none of these singly determines the trend of intergroup
behavior at a given time. They all contribute to the structuring of intergroup behavior, but with
different relative weights at different times. Intergroup behavior at a given time can be explained
only in terms of the entire frame of reference in which all these various factors function
interdependently. This approach, here stated briefly, constituted the starting point of our
experiments on intergroup relations. The approach was elaborated fully in our previous work,
Groups in Harmony and Tension.
The relative weights of various factors contributing to intergroup trends and practices are not
fixed quantities. Their relative importance varies according to the particular set of conditions
prevailing at the time. For example, in more or less closed, homogeneous or highly organized
groups, and in times of greater stability and little change, the prevailing social distance scale
and established practices toward out-group which have been standardized in the past for group
members will have greater weight in determining the intergroup behavior of individual members.
But when groups are in greater functional interdependence with each other and during periods
of transition and flux, other factors contribute more heavily. In these latter cases, there is a
greater discrepancy between expressed attitude and intergroup behavior in different situations,
attributable to situational factors, as insistently noted by some leading investigators in this area
of research. Alliances and combinations among groups which seem strange bedfellows are not
infrequent in the present world of flux and tension.
[p. 200] Because of their influence in social psychology today, two other approaches to
intergroup behavior deserve explicit mention. A brief discussion of them will help clarify the
conception of the experiment reported in this book.
One of these approaches advances frustration suffered in the life history of the individual as the
main causal factor and constructs a whole explanatory edifice for intergroup aggression on this
basis. Certainly aggression is one of the possible consequences of frustration experienced by
the individual. But, in order that individual frustration may appreciably affect the course of
intergroup trends and be conducive to standardization of negative attitudes toward an out-
group, the frustration has to be shared by other group members and perceived as an issue in
group interaction. Whether interaction focusses on matters within a group or between groups,
group trends and attitudes of members are not crystallized from thin air. The problem of
intergroup behavior, we repeat, is not primarily the problem of the behavior of one or a few
deviate individuals. The realistic contribution of frustration as a factor can be studied only within
the framework of in-group and intergroup relations.
The other important approach to intergroup relations concentrates primarily on processes within
the groups in question. It is assumed that measures introduced to increase cooperativeness
and harmony within the groups will be conducive to cooperativeness and harmony in intergroup
relations. This assumption amounts to extrapolating the properties of in-group relations to
intergroup relations, as if in-group norms and practices were commodities easily transferable.
Probably, when friendly relations already prevail between groups, cooperative and harmonious
in-group relations do contribute to solutions of joint problems among groups. However, there
are numerous cases showing that in-group cooperativeness and harmony may contribute
effectively to intergroup competitiveness and conflict when interaction between groups is
negative and incompatible.
The important generalization to be drawn is that the properties of intergroup relations cannot be
extrapolated either (1) from individual experiences and behavior or (2) from the properties of
interaction within groups. The limiting factor bounding intergroup attitudes and behavior is the
nature of relations between groups. Demonstration of these generalizations has been one of
the primary objectives of our experiment.
[p.201] B. The Experiment
The Design in Successive Stages
Experimental Formation of Groups: In order to deal with the essential characteristics of
intergroup relations, one prerequisite was the production of two distinct groups, each with a
definite hierarchical structure and a set of norms. The formation of groups whose natural
histories could thus be ascertained has a decided advantage for experimental control and
exclusion of other influences. Accordingly, Stage l of the experiment was devoted to the
formation of autonomous groups under specified conditions. A major precaution during this
initial stage was that group formation proceed independently in each group without contacts
between them. This separation was necessary to insure that the specified conditions
introduced, and not intergroup relations, were the determining factors in group formation.
Independent formation of distinct groups permitted conclusions to be drawn later from
observations on the effects of intergroup encounters and engagements upon the group
structure.
The distinctive features of our study are Stages 2 and 3 pertaining to intergroup relations. The
main objective of the study was to find effective measures for reducing friction between groups
and to discover realistic steps toward harmonious relations between them. If we had attempted
to get two groups to cooperate without first bringing about a state of friction between them,
there would have been no serious problem to be solved. The great task that social scientists,
practitioners and policy-makers face today is the reduction of prevailing intergroup frictions.
Intergroup Conflict: After formation of definite in-groups, we introduced a period of intergroup
relations as Stage 2 of the experiment. During this stage, the two experimentally formed groups
came into contact under conditions which were competitive, so that the victory of one group
meant loss for the other. This series of encounters was conducive to successive frustrations
whose causes were experienced as coming from the other group.
Only after an unmistakable state of friction between the two groups was manifested in hostile
acts and derogatory stereotypes was the stage of reducing intergroup friction introduced.
[p. 202] Reduction of Intergroup Hostility: Various measures could have been tried in this
experimental attempt toward the reduction of intergroup friction. One possible measure is the
introduction of a "common enemy." Exposed to a common enemy, groups may join hands to do
away with the common threat. This measure was not resorted to because it implies intergroup
conflict on a larger scale.
Another possible approach is through dissemination of specific information designed to correct
prevailing group stereotypes. This measure was not seriously considered because of the large
body of research showing that discrete information, unrelated to central concerns of a group, is
relatively ineffective in changing attitudes. Stereotypes crystallized during the eventful course of
competition and conflict with the out-group are usually more real in the experience of the group
members than bits of information handed down to them.
The alternative of channeling competition for highly valued rewards and prizes along
individualized directions may be effective in reducing intergroup friction by breaking down group
action to individual action. This measure may be practicable for small groups and is attempted
at times by supervisors in classroom and recreational situations. However, frictions and
conflicts of significant consequence in life and the problem of their resolution are in terms of
group demarcations and alignments.
The initial phase of Stage 3 was devoted to testing the effects of intergroup contact involving
close physical proximity in activities that were, satisfying in themselves, such as eating meals or
seeing a movie. This initial phase was introduced with the objective of clarifying the blanket
term "contact" as applied to intergroup relations.
The alternative chosen as the most effective measure for reducing intergroup friction was the
introduction of a series of superordinate goals, in line with the hypothesis stated prior to the
experiment. Superordinate goals are goals of high appeal value for both groups, which cannot
be ignored by the groups in question, but whose attainment is beyond the resources and efforts
of any one group alone.
[p. 203] Research Methods
The methods used in this experiment to bring about the formation and subsequent change of
attitude and behavior ill directions predicted by the hypotheses were neither lecture method nor
discussion method. Instead, the procedure was to place the members of respective groups in
demanding problem situations, the specifications of which met the criteria established for the
experimental stage in question. The problem situations concerned activities, objects or
materials which we knew, on the basis of the expressed preferences of the individuals or the
state of their organisms, were highly appealing to them at the time. Facing a problem situation
which is immediate, which must be attended to, which embodies a goal that cannot be ignored,
group members do initiate discussion, do plan, do make decisions and do carry through the
plans by word and deed until the objective is achieved. In this process, the discussion becomes
their discussion, the plan becomes their plan, the decision becomes their decision, the action
becomes their action. in this process, discussion has its place, planning has its place, action
has its place, and when occasion arises, lecture has its place, too. The sequence of these
related activities need not be the same in all cases. In many instances, we observed two or
three of them carried on simultaneously.
Thus, problem situations introduced in Stage 1 embodied goals of immediate appeal value to
all members-within a group, and the goals required their concerted activity or coordinated
division of labor for attainment. The problem situations of Stage 2 offered goals whose
attainment by one group necessarily meant failure for the other group. Intergroup conflict was
generated in the course of such engagements. The main part of Stage 3 consisted of
introducing a series of situations conducive to super-ordinate goals requiring joint action by
both groups towards common ends. In every stage, changes in attitudes and action were not
attempted through a single problem situation, but through the cumulative effect of a series of
varied activities which, during each stage, had the distinctive characteristics summarized here.
All problem situations were introduced in a naturalistic setting and were in harmony with
activities usually carried out in such a setting. The individuals participating in the study were not
aware that each step was especially designed to study a particular phase of group relations.
Once the problem situation was [p. 204] introduced under specified conditions and at a
specified time, the initiative, discussion and planning were theirs, of course within bounds
insuring health, security and well-being of the individuals studied.
Every effort was made that the activities and the flow of interaction in these activities appear
natural to the subjects. Yet these activities and the interaction in them were experimental:
Problem situations were chosen for each stage according to specified criteria (Chapter 2) and
were introduced under specified conditions (including the place, terrain, time, arrangement of
facilities, stimulus materials available, etc.). The choice of an isolated site made it possible to
restrict interaction situations and the individuals involved in them to those appropriate during
each experimental stage.
Techniques of data collection were also determined by the theoretical approach and
methodological considerations briefly stated above. The subjects were not aware that
behavioral trends reflecting favorable or unfavorable, friendly or hostile intergroup attitudes
were being studied. Knowing that one is under constant observation cannot help becoming a
factor in structuring experience and behavior, particularly when the observation is related to our
status concerns, our acceptance or rejection by others, our good or bad intentions toward
others.
To the subjects, the participant observers appeared to be personnel of a usual camp situation.
They were introduced as senior counselors. In this capacity they were close to their respective
groups in a continuing way. True to their announced roles, the participant observers jotted
down relevant observations out of the subjects' sight, and then expended their notes later each
day.
When the technique of observation is adapted to the flow of interaction, there is danger of being
selective in the choice of events to be recorded. The effective remedy against possible
selectivity is using a combination of methods to check findings obtained with one method
against those obtained by other methods.
The events which revealed stabilization and shifts in statuses, and crystallization of negative
and then positive intergroup attitudes were recurrent and so striking that one could not help
observing them. However, in testing our main hypotheses, we [p. 205] supplemented the
observational method with sociometric and laboratory-like methods. One distinctive feature of
this study was introducing, at choice points, laboratory-like techniques to assess emerging
attitudes through indirect, yet precise indices. Such laboratory-like assessment of attitudes is
based on the finding that under relevant conditions, simple judgments or perceptions reflect
major concerns, attitudes and other motives of man.
Reliability of observation and observer ratings was checked by comparing those of the
participant observer with independent observations by others in crucial test situations. One
such test situation illustrates the technique. When the status hierarchy in one group became
stabilized toward the end of Stage 1, a problem situation was introduced which, like other
problem situations of this stage, required initiative and coordination of the membership. A staff
member who was not with the group regularly and who had not rated the status positions from
day-to-day, observed the group interaction in this situation. On this basis he made independent
ratings of the status hierarchy, which were significantly correlated with those of the participant
observer of that group.
C. Main Conclusions
Individual Characteristics and Intergroup Behavior
In this experiment, the rigorous criteria and painstaking procedures for selecting subjects ruled
out explanations of hostile or friendly intergroup attitudes in terms of differences in socio-
economic, ethnic, religious, or family backgrounds. Similarly, the criteria for subject selection
insured against explanations on the basis of unusual individual frustrations, failures,
maladjustment or instability.
The subjects came from families who were established residents of the same city. They were
stable families composed of natural parents and siblings. No subjects came from broken
homes. Their religious affiliations were similar. They were from the middle socio-economic
class. They were of the same chronological and educational level. They had all made
satisfactory progress academically; none had failed in school. In school and neighborhood, their
social adjustment was above average. None was a behavior problem in home, neighborhood or
school.
[p. 206] In short, they were normal, healthy, socially well-adjusted boys who came from families
with the same or closely similar socio-economic, ethnic, and religious backgrounds.
Since none of the individuals was personally acquainted with others prior to the experiment,
pre-existing positive or negative interpersonal relations did not enter into the rise of intergroup
attitudes.
The conclusion that explanations of the intergroup trends and attitudes on the basis of
individual characteristics are ruled out in this experiment should not be construed to mean that
the relative contributions of individuals within their own groups and in intergroup relationships
are unimportant. Individuals do contribute differentially both in shaping and carrying on the
trend of group relationships. This experiment does indicate, however, that intergroup attitudes
are not merely products of severe individual frustrations or background differences brought to
the situation.
Formation of Group Organization and Norms
When the individuals interacted in a series of situations toward goals with common appeal
value which required interdependent activity for their attainment, definite group structures
arose. These groups developed stable, but by no means immutable status hierarchies and
group norms regulating experience and behavior of individual members.
More concretely, a pattern of leader-follower relations evolved within each group as members
faced compelling problem situations and attained goals through coordinated action. As group
structure was stabilized, it was unmistakably delineated as an "in-group." Certain places and
objects important in group activities were incorporated as "ours." Ways of doing things, of
meeting problems, of behaving under certain conditions were standardized, permitting variation
only within limits. Beyond the limits of the group norms, behavior was subject to group
sanctions, which ranged from ridicule, through ignoring the offender and his behavior, to
threats, and occasionally to physical chastisement.
[p. 207] In-Group Cooperativeness Is Not Directly Transferable
When two groups met in competitive and reciprocally frustrating engagements, in-group
solidarity and cooperativeness increased. Toward the end of intergroup friction (Stage 2), in-
group solidarity became so strong that when the groups were taken to a public beach crowded
with outsiders and affording various distractions, our groups stuck almost exclusively to
activities within their respective in-groups. Psychologically, other people did not count as far as
they were concerned. In the presence of so many people and distractions, this intensive
concentration of interests and activities within the group atmosphere would have been
impossible had the groups gone there before attaining such a high degree of solidarity.
This heightened in-group solidarity and cooperativeness were observed at the very time when
intergroup hostility was at its peak, during the period when the groups asserted emphatically
that they would not have anything more to do with each other. This can only mean that the
nature of intergroup relations cannot be extrapolated from the nature of in-group relations. In-
group solidarity, in-group cooperativeness and democratic procedures need not necessarily be
transferred to the out-group and its members. Intergroup relations cannot be improved simply
by developing cooperative and friendly attitudes and habits within groups.
Consequential Intergroup Relations Affect In-group Relations
Special note should be made of a related finding, namely that consequential intergroup
relations have an impact on the in-group organization.
When it became evident that certain members of one group, including the leader, were not
living up to the responsibilities expected of them by other members during the eventful course
of intergroup competition, leadership changed hands. Those individuals who distinguished
themselves by giving a good account for their group rose in the status hierarchy. Internal shifts
in status were observed again during the cooperative intergroup activities of Stage 3.
Functional relations between groups which are of consequence tend to bring about changes in
the pattern of in-group relations.
[p. 208] Limiting Conditions for Intergroup Attitude and Behavior
We have seen that the individuals studied in this experiment were selected in ways which rule
out explanations for the direction of intergroup behavior on the basis of differences in their
backgrounds or on the basis of their individual frustrations, instabilities and the like. In the
preceding sections, we have seen evidence that in-group properties were affected by
consequential intergroup relations. Thus the intergroup hostility and its reduction cannot be
explained merely by the nature of relationships within the groups.
Our findings indicate that the limiting condition determining friendly or hostile attitudes between
groups is the nature of functional relations between them, as defined by analysis of their goals.
When the groups competed for goals which could be attained by only one group, to the dismay
and disappointment of the other, hostile deeds and unflattering labels developed in relation to
one another. In time, derogatory stereotypes and negative attitudes toward the out-group were
crystallized. These conclusions are based on observations made independently by observers of
both groups and other staff members. Sociometric indices pointed to the overwhelming
preponderance of friendship choices for in-group members. Experimental assessment of
intergroup attitudes showed unmistakable attribution of derogatory stereotypes to the villainous
out-group and of favorable qualities to the in-group. Laboratory-type judgments of performance
showed the tendency to overestimate the performance attributed to fellow group members and
to minimize the performance of members of the out-group.
What Kind of Contact Between Groups is Effective?
The novel step in this experiment was Stage 3, in which intergroup friction was reduced. We
have already stated why we discarded certain procedures in this stage, such as introducing a
"common enemy" or disseminating information. In order to clarify the term "contact," we tried
the method of bringing the groups into close proximity in a series of activities. Most of these
contact situations involved activities which were satisfying in themselves, such as eating good
food in the same room, attending a movie together, or engaging in an exciting activity like [p.
209] shooting fireworks. But none of them created a state of interdependence between the
groups. Such contact situations did not prove effective in reducing friction. Instead contact
situations not conducive to interdependence were used by our groups for overt acts of hostility
and further exchanges of unflattering invectives.
The ineffectiveness of contacts during which hostile groups engaged, while in close physical
contiguity, in activities which were themselves satisfying to each individual has obvious
implications for psychological theorizing.
The Introduction of Superordinate Goals
During the final period of the experiment, the prevailing friction between groups was reduced.
Reduction of the conflict and hostility was observed in reciprocally cooperative and helpful
intergroup actions, in friendly exchanges of tools, in developing standard procedures for
alternating responsibilities and in meeting problems. The change in behavior and patterns of
interaction between the groups was striking to all observers. The reliability of these
observations is established by sociometric indices which showed increases of friendship
choices for the erstwhile antagonists and also in the sharp decrease of unfavorable stereotypes
toward the out-group. Favorable conceptions of the out-group developed, so that ratings of the
in-group and out-group were no longer a set of contrasted polarities.
The end result was obtained through introduction of a series of superordinate goals which had
compelling appeal value for both groups but which could not be achieved by the efforts and
resources of one group alone. When a state of interdependence between groups was produced
for the attainment of superordinate goals, the groups realistically faced common problems.
They took them up as common problems, jointly moving toward their solution, preceding to plan
and to execute the plans which they had jointly envisaged.
In this experiment, the setting and circumstances for the introduction of superordinate goals
were elaborately prepared by the experimenters. But beyond setting the scene, the methods
followed, the discussion necessary for the solution, the plans to [p. 210] be made and executed
were left to the groups themselves. Faced with superordinate goals, the groups carried on
discussion when necessary, listened to the advice and suggestions of members of both groups
who were resourceful, made decisions, and even combined discussion, decision and deeds
simultaneously when the goal was attained more effectively this way.
Cumulative Effects of Superordinate Goals
If the hostile attitudes generated during intergroup friction had any stability, it could not be
expected that one or two situations embodying superordinate goals could wipe them out.
Indeed intergroup antagonisms did not disappear in one stroke. At first, cooperative interaction
involving both groups developed in specific situations in response to common problems and
goals, only to be followed by a renewal of sharply drawn group lines and intergroup friction after
the challenge had been met. Patterns and procedures for intergroup cooperation were laid
down at first on a small scale in specific activities. Only during interaction in a series of
situations involving superordinate goals did intergroup friction begin to disappear and the
procedures for intergroup reciprocity developed in specific situations extend spontaneously to
widening areas of activity.
In the sequential events of Stage 3 (Chapter 7), it was abundantly evident that the series of
activities conducive to superordinate goals provided opportunities for members of the two
groups to work out and develop procedures for cooperation in various spheres of action. Once
a cooperative pattern was effective in a specific activity, it was extended by members of both
groups to related actions. In the face of successful functioning of such procedures, the
occasional dissident member who preferred the old days of intergroup strife or self-imposed
separation found it more difficult to make his voice count in his own group.
Some procedures successful in intergroup interaction had previously been used by the groups
in meeting problems within their own groups. But their transfer to intergroup interaction involved
a significant step: the tacit recognition that the procedures now involved groups of individuals
and not merely so many individual members within a group. Each individual within his group
had been expected and encouraged by others to contribute to group efforts to the best of his
abilities. Now, each [p. 211] group expected the other to contribute its share to meeting
intergroup problems. While previously solutions were experienced as equitable or not relative to
the individual's expectations and contributions within his group, now justice was also evaluated
relative to equitable participation and opportunity for the groups as well.
The Same Tools May Serve Intergroup Conflict or Cooperation
In planning and working towards superordinate goals, there were times when the groups used
jointly the tools and techniques which had been used by one or both groups separately in the
service of tights during the intergroup conflict. Tools and techniques can be put to the service of
harmony and integration as well as of deadly competition and conflict. Tools, in themselves, are
not opposed to cooperation among individuals using them. It is the individuals as group
members who put the tool to use in their opposition to other groups.
Even the proprietary pride that a place, a technique, a tool is "ours" takes on a different
significance when the trend in intergroup relations is cooperation toward superordinate goals.
Use of the technique or the tool in intergroup activities now implies a contribution toward a goal
common to both groups - a contribution by the group in which members may take personal
pride and which can be reciprocated by the other group equally enjoying its benefits through its
own contributions at that or future occasions.
Superordinate Goals Alter the Significance of Other Influences
Contacts between groups in the course of actions towards superordinate goals are effective.
They are used for developing plans, making decisions, and for pleasant personal exchanges.
Information about the out-group becomes a matter of interest to group members and is actually
sought in the course of interactions between members of the two groups. Leaders find that the
trend toward intergroup cooperation in activities involving superordinate goals widens the
spheres in which they may take positive steps toward working out procedures for joint
endeavors and planning future contacts. Mingling with members of the other group and sharing
in activities with them is no longer perceived.
[p. 212] by in-group members as "betrayal" or "treason". Similarly, the out-group member who
engages in activities with the in-group is no longer seen by them as a strange and threatening
figure in "our midst." On the contrary, intermingling of persons from different groups becomes a
joint opportunity to work towards goals shared by both groups.
These are products of interaction toward goals superordinate to all groups, which are genuinely
appealing to all, whose attainment requires equitable participation and contributions from all
groups in interdependent activities.
