Abstract
Ingroup bias and outgroup prejudice are pervasive features of human behavior, motivating various forms of discrimination and conflict. In an era of increased cross-border migration, these tendencies exacerbate intergroup conflict between native populations and immigrant groups, raising the question of how conflict can be overcome. We address this question through a large-scale field intervention conducted in 28 cities across three German states, designed to measure assistance provided to immigrants during everyday social interactions. This randomized trial found that cultural integration signaled through shared social norms mitigates—but does not eliminate—bias against immigrants driven by perceptions of religious differences. Our results suggest that eliminating or suppressing ascriptive (e.g., ethnic) differences is not a necessary path to conflict reduction in multicultural societies; rather, achieving a shared understanding of civic behavior can form the basis of cooperation.
