One hundred fifty-five men and 256 women were assessed on authoritarianism, social dominance, and other personality traits. Authoritarianism showed few correlations with personality measures; however, social dominance correlated with disagreeableness, coldness, vindictiveness, and aggressiveness for all participants and with masculine interests for men. Ninety-three questionnaire participants (47 men and 16 women) were interviewed and rated on various personality traits. Both authoritarianism and social dominance were highly judgable from interviews. Authoritarian individuals, especially men, were judged to be defensive, maladjusted, and prejudiced. Socially dominant individuals, especially women, were judged to be disagreeable, cold, and prejudiced. Authoritarianism correlated particularly strongly with negative attitudes toward homosexuality, and social dominance with the endorsement of gender inequality. Results are discussed in terms of two kinds of dispositional prejudice. (C) 1999 Academic Press.
