Abstract. Prior research has reported less favorable attitudes toward and more violent crimes against ethnic out-group members in East (vs. West) Germany. We conducted two pre-registered lost letter studies in West versus East German cities (Study 1, N = 400) and in West versus East German rural areas (Study 2, N = 400). To investigate supportive behavior regarding refugee integration, we manipulated the addressee (refugee-integration vs. immigration-stop projects). Contrary to predictions, letter return rates did not differ between West and East Germany. Across western and eastern German regions, return rates were higher for the refugee-integration project in urban areas while no differences emerged in rural areas. A pooled analysis found greater support for the refugee-integration (vs. immigration-stop) project.
