This study investigated U.S. ethnic majority and minority youth's perceptions of fair and unfair treatment by authorities and evaluations of three situations of interracial exclusion (N = 685). Findings revealed that older adolescents who reported fair treatment by authorities were more likely to perceive wrongfulness in interracial exclusion scenarios than were their peers who reported unfair treatment. Additionally, in explaining the wrongfulness of interracial exclusion, older adolescents who had not experienced unfair treatment by authorities were more likely to mention racial prejudice than were their counterparts who had experienced unfair treatment. Results are discussed with reference to developmental theory on authority relations and the positive benefits of authority-adolescent relationships that reflect just and fair treatment.
