RWA and SDO are the strongest individual-difference predictors of prejudice

Evidence

The SDO scale powerfully predicts a range of sociopolitical and intergroup phenomena similar to those predicted by the RWA scale. Nevertheless, the two scales are relatively independent (nonsignificantly or only weakly correlated) and predict prejudice independently of each other (Altemeyer, 1998; McFarland, 1998; Pratto et al., 1994). Moreover, studies using a large number of individual-difference variables (i.e., personality, cognitive style, or social values and attitudes) to simultaneously predict prejudice found that both RWA and SDO were powerful predictors of prejudice when all other variables were controlled, and no other psychological variables were able to explain materially significant variance in generalized prejudice once RWA and SDO were controlled (Altemeyer, 1998; McFarland, 1998; McFarland & Adelson, 1996). Thus, RWA and SDO appear to be the strongest individual-difference predictors of prejudice. — John F. Dovidio, Peter Glick, Laurie A.

It has produced an extraordinary measure of prejudice. Indeed, with some help from the RWA scale this test explains most of the prejudice in the samples studied thus far. That amazes me. Also the SDO scale provides the best measure we have of the missing link in the domination-submission authoritarian social system—a link I never realized was missing. Furthermore, high SDOs certainly grip one, and merit study in their own right. And finally, social dominance orientation helps explain most of the confusing findings that have popped up thus far in research using the RWA Scale. — John T.
