We tested the joint influence of individual difference and situational factors on implicit group prejudice. Participants in Experiments 1 and 2 were briefly shown in-group or out-group pronouns prior to evaluating good or bad trait adjectives. Under standard conditions (Experiment 1), there was no difference between participants with high and low social dominance orientation (SDO), but when the intergroup context was made more salient (Experiment 2), high-SDO participants alone showed implicit group prejudice. Implications for the malleability and consensuality of implicit prejudice are discussed.

The authors tested three hypotheses from social dominance theory in four cultures: (a) that individual differences in social dominance orientation (SDO), or the preference for group-based inequality, can be reliably measured in societies that are group-based hegemonies; (b) that SDO correlates positively with attitudes supporting hegemonic groups and correlates negatively with attitudes supporting oppressed groups; and (c) that men are higher on SDO than women. For the most part, the results confirmed the hypotheses. SDO scales were internally reliable and were administered in English, Chinese, and Hebrew. SDO scores correlated with sexism, measured in culturally appropriate ways, in every culture, and with ethnic prejudice and other attitudes concerning the local hegemony except in China. Men were higher on SDO than women in most samples. Findings are discussed in terms of ideological and psychological facilitators of group dominance.
