Social identity complexity (SIC) as defined by Roccas and Brewer is an individual’s subjective representation of the combination of his or her multiple ingroup memberships. Almost all prior research on SIC and its relationship to intergroup attitudes has been conducted with members of ethnic majority groups. The present research assesses SIC and its correlates among ethnic majority group members (Anglo-Australian students) and members of a salient ethnic minority group (Asian-Australian students). Study 1 found that Asian-Australians perceived significantly more overlap among their ingroups (lower SIC) than did Anglo-Australians, despite the fact that objective overlap is actually greater for majority than minority ethnic groups. Study 2 replicated this difference and found that perceived overlap was predicted by proportion of ingroup friends. Further, for the majority group, low SIC is associated with less inclusive Australian identity, but for minority group members, SIC and Australian identity inclusiveness are essentially independent. Results are discussed in terms of the social-structural environment in which multiple identities are managed.
