Positive social contact between members of ethnic or religious groups in conflict can reduce discriminatory behavior – while prejudice remains unchanged, a new study shows. It is based on a field experiment among Christian and Muslim young men, that was undertaken in a riot-prone city in Nigeria by WZB researcher Alexandra Scacco and Shana S. Warren (New York University). The study offers key insights for policy makers who implement peacebuilding and youth programming interventions in conflict and post-conflict regions.
