Congruity theory is used as the basis for predictions made in this study. The study deals with the effect that 1) extrinsic ethos, and 2) general susceptibility to persuasion have on a prejudiced or non-prejudiced person's degree of persuasibility to a one-sided persuasive message presented by either a white or black source. Eighty-eight white college students heard a message. Of these, 39 had the message attributed to a black source and 49 had it attributed to a white source. The results showed that white high-prejudice individuals will attemt to disassociate a message from a black source, associate the message with a white source seen as "like me," and consequently be more susceptible to persuasion. White low-prejudiced individuals are equally persuaded by either a white or black message source. (Author/JK)
