Uncertainty, Social Identity, and Ideology

A social identity analysis, based on Hogg's (2000) uncertainty reduction theory, of the emergence and maintenance of ideological belief systems is presented. Uncertainty, particularly self-uncertainty, motivates identification with high-entitativity groups and behaviors that promote entitativity. Under more extreme uncertainty, identification is more pronounced and entitativity can be associated with orthodoxy, hierarchy and extremism, and with ideological belief systems. I develop and describe a social identity and uncertainty reduction analysis of ideology, and contextualize this in a brief discussion of the concept of ideology and in coverage of other contemporary social psychological treatments of ideology, such as social dominance theory, system justification theory, right-wing authoritarianism, belief in a just world, and the protestant work ethic.
