Most theories in social and political psychology stress self-interest, intergroup conflict, ethnocentrism, homophily, ingroup bias, outgroup antipathy, dominance, and resistance. System justification theory is influenced by these perspectives—including social identity and social dominance theories—but it departs from them in several respects. Specifically, we argue that (a) there is a general ideological motive to justify the existing social order, (b) this motive is at least partially responsible for the internalization of inferiority among members of disadvantaged groups, and (c) paradoxically, it is sometimes strongest among those who are most harmed by the status quo. In this article, we review and integrate 10 years of research on 20 hypotheses derived from a system justification perspective, focusing especially on the phenomenon of implicit outgroup favoritism among members of disadvantaged groups (including African Americans, the elderly, and gays/lesbians) and its relation to political ideology (especially liberalism-conservatism).
