Recent research suggests that inducing fixed (rather than malleable) beliefs about groups leads to more negative attitudes toward out-groups. The present paper identifies the underlying mechanism of this effect. We show that individuals with a fixed belief about groups tend to construe intergroup settings as threatening situations that might reveal shortcomings of their in-group (perceived threat). In the present research, we measured (Study 1) and manipulated (Study 2) participants' lay theories about group malleability. We found that the extent to which individuals had an entity (versus an incremental) group theory influenced the level of threat they felt when interacting with out-group members, and that perceived threat in turn affected their level of ethnocentrism and prejudice. These findings shed new light on the role of lay theories in intergroup attitudes and suggest new ways to reduce prejudice. Copyright © 2015 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Decades of research have shown that social dominance orientation (SDO) is one of the most important predictors of anti‐immigrant attitudes. However, the mechanisms through which SDO can explain prejudice have been studied insufficiently. Using rich and diverse samples from France and from the province of Québec in Canada, the present research provides a cross‐national (N = 1,852) and prospective (N = 534) analysis of a theoretical model in which the dimensions of SDO are indirectly predicting anti‐immigrant prejudice via the intergroup ideologies of assimilation, multiculturalism, colour blindness and interculturalism. Results showed that interculturalism, a hierarchy‐attenuating ideology was found to be a robust mechanism to explain the subtle effects of SDO‐E on anti‐immigrant prejudice whereas assimilation, a hierarchy‐enhancing ideology was playing a more important role to explain direct and blatant effects of SDO‐D on prejudice. The two most studied diversity approaches, multiculturalism and colour blindness, were largely redundant once interculturalism was considered. This pattern occurred in both France and Québec hence, favouring the context‐independent pathway. [ABSTRACT FROM AUTHOR]
