Replication Data for: Educating for inclusion: Diversity education programs can reduce prejudice towards outgroups in Israel

Intergroup prejudice is pervasive in many contexts worldwide, leading to discrimination and conflict. Existing research suggests that prejudice is acquired at an early age and that durably improving intergroup relations is extremely challenging, often requiring intense theoretically informed interventions. Building on existing research in social psychology and inspired by the Israeli TV series \"You Can't Ask That,\" which depicts charismatic children from minority groups broaching sensitive topics at the core of intergroup relations, we develop a monthlong diversity education program. Our program exposed students to the TV series and facilitated follow-up classroom discussions in which students constructively addressed various sensitive topics at the core of intergroup relations and learned about intergroup similarities, intragroup heterogeneity, and the value of taking others' perspectives. Through two field experiments implemented in Israeli schools, we show that integrating our intervention into school curricula improved Jewish students' attitudes towards minorities and increased some pro-diversity behavior up to 13 weeks post-treatment. We further provide suggestive evidence that the intervention was effective by encouraging students to take their outgroups' perspectives and address an element of scalability by delegating implementation responsibilities to classroom teachers in our second study. Our findings suggest that theoretically informed intensive education programs are a promising route to reducing prejudice at a young age.
