Individuals defend and rationalize social systems in order to maintain the belief that the world in which they live is fair and good. This justification often involves seeing intergroup inequality as legitimate and holding negative attitudes toward lower status groups. Although research on system justification is plentiful, the effects of perceived threat to the system on intergroup interaction behavior and dynamics have remained unexamined. With ethnic diversity increasing in North America, it is imperative that we understand the factors that promote more positive (and negative) intergroup interactions. Across three studies I examined individuals’ reactions to system threatening information versus low threat in the context of an intragroup or intergroup interaction. In general, priming dominant group members with system threat (versus low threat) led to less negative intergroup interaction behavior. Specifically, being primed with system unfairness led dominant group members in Study 1 to express more positive other-directed remarks during a written exchange with an ostensible outgroup member. Study 2, conducted with a different minority group than Study 1, found that dominant group members feel more guilt when interacting with minority group members versus members of their own group in the face of system threat. Finally, a face-to-face intergroup interaction study replicated the positive behavioral effects of salient system threat found in Study 1, this time manifest in increased nonverbal friendliness and self-disclosure for both pair members. These findings suggest that system threat instantiated in an interaction setting leads dominant group members toward exhibiting more positive behavior to minority group members that benefits both parties involved, rather than toward derogation. Implications for social change initiatives are discussed.

本研究では，外集団から内集団に対して抱かれているイメージに関する認知（メタステレオタイプ）の働きに焦点を当て，そのような集団間葛藤の問題における新たなモデルや低減方法について議論した。 / Unfriendliness towards members of an out-group is considered to be shaped not only by an individual's beliefs about members of the out-group (stereotypes), but also by an individual's beliefs about how members of the out-group view his or her own group (meta-stereotypes). This dissertation investigated the role of negative meta-stereotypes in intergroup interactions and suggested factors that can change negative attitudes towards the members of the out-group. / 博士(心理学) / Doctor of Philosophy in Psychology / 同志社大学 / Doshisha University
