Stigmatized sources and persuasion: Prejudice as a determinant of argument scrutiny.

Abstract

Two experiments examined the viability of several explanations for why majority group individuals process persuasive messages from stigmatized sources more than those from nonstigmatized sources. In each study, majority group participants who either were high or low in prejudice or were high or low in ambivalence toward a stigmatized source's group were exposed to a persuasive communication attributed to a stigmatized (Black, Experiment 1; homosexual, Experiment 2) or nonstigmatized (White, Experiment 1; heterosexual, Experiment 2) source. In both studies, source stigmatization increased message scrutiny only among those who were low in prejudice toward the stigmatized group. This finding is most consistent with the view that people scrutinize messages from stigmatized sources in order to guard against possibly unfair reactions by themselves or others.
