Authoritarians are less educated but education explains little of their behavior

Evidence

Education. University students differ little among themselves in educational attainment, so there is no risk that findings obtained with students have been confounded by years of schooling. On the other hand, many studies of nonstudent samples have shown that authoritarians tend to be less educated. But the RWA-education relationships have almost always ranged between . and .30. Controlling for this connection reduces RWA-criterion coefficients very little. — Bob Altemeyer, The Authoritarian Specter, 554
