The persuasive “power” of stigma?

We predicted that able-bodied individuals and White Americans would have a difficult time saying no to persuasive appeals offered by disabled individuals and Black Americans, due to their desire to make such interactions proceed smoothly. In two experiments, we show that members of stigmatized groups have a peculiar kind of persuasive “power” in face-to-face interactions with non-stigmatized individuals. In Experiment 1, wheelchair-bound confederates were more effective in publicly soliciting donations to a range of charities than confederates seated in a regular chair. In Experiment 2, Whites changed their private attitudes more following face-to-face appeals from Black than White confederates, an effect mediated by their increased efforts to appear agreeable by nodding and expressing agreement. This difference was eliminated when impression management concerns were minimized – when participants viewed the appeals on video.

► People can experience discomfort when interacting with stigmatized individuals.
► This discomfort lends stigmatized individuals persuasive “power”.
► Wheelchair-bound individuals were more effective in soliciting donations.
► Whites changed their attitudes more following appeals from Blacks than Whites.
► Efforts to appear agreeable underlie the impact of stigma on persuasion.
