Rokeach’s dogmatism model came from personal theorizing, not data

Evidence

The resulting model, in all its complexity, cannot be said to have been guided by a particular theory in psychology (as the Berkeley model was by psychoanalytic theory), or developed from mindless, grind-‘em-out item-testing experiments (the way my model of right-wing authoritarianism was inferred). Instead, it mainly flowed from Rokeach’s own thinking about ideologies. — Bob Altemeyer, The Authoritarian Specter, 2539
