The effectiveness of Jane Elliott's well-known “blue-eyes/brown-eyes” exercise in reducing college students’ stereotyping and prejudice was assessed. College students were randomly assigned to either the exercise group or a comparison group. Blue-eyed and brown-eyed exercise participants were given discriminatory versus preferential treatment, respectively; a procedure purportedly designed to sensitize participants to the emotional and behavioral consequences of discrimination. Participation in the exercise was found to be associated with White students (a) indicating significantly more positive attitudes toward Asian American and Latino/Latina individuals, but only marginally more positive attitudes toward African American individuals; and (b) reporting anger with themselves when noticing themselves engaging in prejudiced thoughts or actions—negative affect that theoretically could prove to be either helpful or detrimental in promoting long-term reduction of stereotyping and prejudice.
