the "general desire for unequal relations among social groups, regardless of whether this means ingroup domination or ingroup subordination" (p. 312). Given these changes, Rubin and Hewstone believe that evidence for social dominance theory should be considered "as supporting three separate SDO hypotheses, rather than one single theory" (p. 22). Group-based and individual dominance Robert Altemeyer said that people with a high SDO want more power (agreeing with items such as "Winning is more important than how you play the game") and are higher on Machiavellianism. These observations are at odds with conceptualisations of SDO as a group-based phenomenon, suggesting that the SDO reflects interpersonal dominance, not only group-based dominance. This is supported by Sidanius and Pratto's own evidence that high-SDO individuals tend to gravitate toward hierarchy-enhancing jobs and institutions, such as law enforcement, that are themselves hierarchically structured vis-a-vis individuals within them. Relations with other personality traits Connection with right-wing authoritarianism SDO correlates weakly with right-wing authoritarianism (RWA) (r ≈ .18). Both predict attitudes, such as sexist, racist, and heterosexist attitudes. The two contribute to different forms of prejudice; SDO correlates to higher prejudice against subordinate and disadvantaged groups, RWA correlates to higher prejudice against groups deemed threatening to traditional norms, while both are associated with increases in prejudice for "dissident" groups. SDO and RWA contribute to prejudice in an additive rather than interactive way (the interaction of SDO and RWA accounted, in one study, for an average of less than .001% variance in addition to their linear combination), that is the association between SDO and prejudice is similar regardless of a person's level of RWA, and vice versa. Crawford et al. (2013) found that RWA and SDO differentially predicted interpretations of media reports about socially threatening (for example, gays and lesbians) and disadvantaged groups (for example, African Americans), respectively. Subjects with high SDO, but not RWA, scores reacted positively to articles and authors that opposed affirmative action, and negatively to pro-affirmative-action article content. Moreover, RWA, but not SDO, predicted subjects' evaluations of same-sex relationships, such that high-RWA individuals favored anti-same-sex relationships article content and low-RWA individuals favorably rated pro-same-sex relationships content. Correlation with Big Five personality traits Studies on the relationship of SDO with the higher order Big Five personality traits have associated high SDO with lower openness to experience and lower agreeableness. Meta-analytic aggregation of these studies indicates that the association with low Agreeableness is more robust
