SDO and RWA jointly explain half of overall prejudice variance

Evidence

The results which could have been quite gnarly proved utterly simple in both samples. SDO scores correlated about . with McFarland and Adelson’s index of overall prejudice, while RWA answers notched a .47. The two tests barely interconnected (. and .07), so when you plunked them into a regression analysis, they explained different segments of overall prejudice and served up a multiple r of . in each sample. None of the other personality tests mattered much once these two scales had their say. In fact, gender entered the equation next among the students, ahead of all the remaining scales (with males being more prejudiced than females). — John T.
