The Influence of Social Consensus Information on Intergroup Attitudes: The Moderating Effects of Ingroup Identification

Abstract

ABSTRACT Two studies examined the role of ingroup identification in the influence of social consensus information (information about others' beliefs) on intergroup attitudes. Research demonstrates that consensus information influences individuals' intergroup attitudes. However, the extent to which individuals identify with the group providing consensus information seems important to understanding consensus effects. In Study 1, 100 high or low ingroup identifiers received information that other ingroup members held favorable or unfavorable attitudes toward African Americans and then provided their own attitudes. In Study 2, 250 participants completed an ingroup identification manipulation (high, low, or control) before receiving favorable or no consensus information. Results of both studies demonstrated that ingroup identification moderated consensus effects, such that high identifiers were more susceptible to others' beliefs than individuals in the low identification and control conditions. In determining critical factors involved in consensus effects, we hope to create a useful method to promote favorable intergroup attitudes and behaviors.
