Self-Expansion and Intergroup Contact: Expectancies and Motives to Self-Expand Lead to Greater Interest in Outgroup Contact and More Positive Intergroup Relations

Sixty years of research on intergroup contact demonstrates that positive interactions across group boundaries can improve intergroup attitudes and can contribute to forging tolerant, integrated, multicultural societies. However, to fully realize the benefits of growing diversity around the globe, individuals need to exploit opportunities for intergroup contact that are available to them. Yet, it is relatively unknown why people might deliberately engage in cross-group interactions and how individuals' expectations and motives prepare them to develop positive interpersonal relationships with outgroup members. In this article, we begin to address these research gaps. We discuss the self-expansion model and present new evidence that is consistent with this model. Two studies, one correlational in a cross-cultural setting and the other experimental, show the value of high self-expansion expectancies and motivation in promoting interest in and producing more and higher quality interactions across group boundaries. We discuss implications of these findings for policy and intervention.
