First published in 1976, this A Theory of Group Structures is a study of the aggregation of individuals into groups, which cuts across many different social sciences.

Volume one attempts to formulate a more rigorous theory of group structures by providing consistent definitions, assumptions, measures, methodology, theory and results. Volume two examines a sequence of twelve experiments and reports empirical tests of the theory presented in volume one. The result is a major revision of existing research into problems of group structure and a case study in paradigm development.

This book will be of interest to students of all social sciences.
