Intergroup Conflict and Cooperation: The Robbers Cave Experiment HTML version

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
