Diversity in health care institutions reduces Israeli patients’ prejudice toward Arabs

Abstract

Diversity in the lines of public institutions, such as hospitals, schools, and police forces, is thought to improve provision for minority group members. Nonetheless, whether and how diversity in public institutions shapes majority citizens' prejudice toward minorities are unclear. Building on insights from the intergroup contact literature, I suggest that diversity in public institutions can facilitate positive intergroup contact between majority group members and minorities in elevated social positions. Such unique interactions, which exceed the equal status condition for effective intergroup contact, can serve to reduce prejudice and facilitate more inclusive attitudes among majority group members. To test this expectation, I focus on health care provision-a leading sector with regard to minority representation. Leveraging a natural experiment unfolding in 21 Israeli medical clinics where Jewish patients are haphazardly assigned to receive care from Jewish or Arab doctors and embedding prejudice-related questions in a routine evaluation survey, I demonstrate that brief contact with an Arab doctor reduces prejudice. Specifically, contact with an Arab doctor reduces Jewish patients' exclusionary preferences toward Arabs by one-sixth of an SD and increases Jewish patients' optimism about peace by a 10th of an SD. The modest magnitude of these effects is similar to the impact of well-powered interventions recently reviewed in a meta-analysis of prejudice reduction experiments. These findings emphasize how the demographic makeup of public institutions can reduce mass prejudice, even in a context of intractable conflict.
