Assimilation and diversity: An integrative model of subgroup relations

A model of sociostructural relations among subgroups within a superordinate category is presented. Contextualized by discussion of political and social psychological models of intergroup contact, we extend principles of social identity theory to address structural differentiation within groups. Subgroup identity threat plays a pivotal role in the nature of subgroup relations, as do the social realities of specific subgroup relations (i.e., inclusiveness, nested vs. crosscutting categories, leadership, instrumental goal relations, power and status differentials, subgroup similarity). Our analysis suggests that subgroup identity threat is the greatest obstacle to social harmony; social arrangements that threaten social identity produce defensive reactions that result in conflict. Social harmony is best achieved by maintaining, not weakening, subgroup identities, and locating them within the context of a binding superordinate identity.
