Evidence

There may, in fact, be real differences between groups that inform the images people hold of one another and the evaluations they make (Campbell, 1967). For that reason, affective hostility alone, in the absence of an exaggerated or faulty stereotype, may not be a form of prejudice. — John T. Jost and Jim Sidanius, Political Psychology, 3396
