Individual,social group and intergroup behaviour. Some conceptual remarks on the social identity theory

An investigation of the group concept proposed by Tqjfel and Turner shows that group formation and intergroup behaviour cannot be explained by the similarity of group members. Taking into account only similarity of elements leads to conceptual contaminations concerning group and class, group and collective, personal and social identity, and finally interpersonal and intergroup behaviour. It is claimed that only the consideration of group structure and the differentiation of partially individual and partially structural attributes of the group members results in a conceptually adequate theory of group formation and intergroup behaviour of its members.
