SDO predicts generalized prejudice while RWA predicts religion-based prejudice

Evidence

SDO and RWA correlated only .08, but both predicted ethnocentrism (. and .27, respectively) and hostility toward homosexuals (. and .70). Together they explained 56% of the variance of the sum of standardized scores from these two prejudice scales, with RWA taking the lead because of its strong relationship with attitudes toward homosexuals. (This is not surprising, as it mentions homosexuals in several items, whereas the SDO scale piles up its correlations without naming any particular group.) Social dominance orientation did not correlate with religious fundamentalism (−.04) nor with emphasis placed on religion while growing up (−.17), but RWA did, . and .58. Once again, social dominance cropped up more among guys (.30), but authoritarianism did not (.11). — John T. Jost and Jim Sidanius, Political Psychology, 965
