A model of the ingroup as a social resource.

Drawing on theories of social comparison, realistic group conflict, and social identity, we present an integrative model designed to describe the psychological utility of social groups. We review diverse motivations that group membership may satisfy (e.g., the need for acceptance or ideological consensus) and attempt to link these particular needs to a global concern for self-worth. We then examine several factors hypothesized to influence an ingroup's utility in the eyes of its members. Attempting to unite our understanding of (a) why groups are needed and (b) what kinds of groups are useful in meeting those needs, a proposed model of the ingroup as a social resource (MISR) suggests that the dimensions of perceived value, entitativity, and identification interact to determine the overall psychological utility of an ingroup. We discuss empirical and theoretical support for this model, as well as its implications for intra- and intergroup attitudes.
