Differential effects of right wing authoritarianism and social dominance orientation on outgroup attitudes and their mediation by threat from and competitiveness to outgroups.

A dual-process model of individual differences in prejudice proneness proposes that Right Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) will influence prejudice against particular outgroups through different motivational mechanisms. RWA should cause negative attitudes toward groups seen as threatening social control, order, cohesion, and stability, such as deviant groups, and negativity toward these groups should be mediated through perceived threat from them. SDO should cause negative attitudes toward groups that activate competitiveness over relative dominance and superiority, such as socially subordinate groups low in power and status, and negativity toward these groups should be mediated through competitiveness toward them. Findings from four student samples that assessed attitudes toward seven social groups selected as likely to vary systematically in social threat and social subordination supported these predictions. The findings have implications for reconciling intergroup and individual difference explanations of prejudice and for interventions to reduce prejudice.
