“Everybody knows it’s true”: Social dominance orientation and right-wing authoritarianism moderate false consensus for stereotypic beliefs

European American university students (N = 89) judged the percentage of African Americans who possess 16 traits (e.g., poor, violent, and emotionally expressive) and then estimated how other students would make the same judgments. Participants also completed measures of social dominance orientation (SDO) and right-wing authoritarianism (RWA). Individuals with both high SDO and high RWA held the least positive views of African Americans. False consensus emerged in the form of a significant positive average within-person partial correlation between participants’ own ratings and their judgments of how other students would respond, controlling for the actual responses of other students. False consensus was positively related to SDO and a significant SDO × RWA interaction indicated that false consensus was highest for participants with both high SDO and high RWA. Results suggest that hierarchy-legitimizing beliefs in the form of stereotypes may be sustained internally through false consensus, especially among those most prone to prejudice.
