Abstract
Bringing members of different social groups into contact is thought to be as one of the most promising approaches for improving intergroup relations. Indeed, a plethora of studies has shown that this intergroup contact is an effective means not only to reduce mutual prejudice but also to increase trust and forgiveness. In this chapter, we will first review evidence for the effectiveness of intergroup contact and introduce different forms of intergroup contact – direct (i.e., face-to-face contact) as well as more indirect forms of contact (i.e., extended, vicarious, and imagined contact). We will then discuss moderators (e.g., types of in- and outgroup categorization) and mediators (e.g., intergroup anxiety and empathy) of contact effects as well as potential unintended effects of intergroup contact. Finally, we will summarize research on the effectiveness of intergroup contact interventions and give two examples of such interventions that have been implemented in the context of conflictual intergroup relations (i.e., Israeli-Palestinian conflict and Hutu-Tutsi conflict in Rwanda).
