He received a Ph.D. from the University of Wisconsin-Madison in August 2022 after spending two years as a Middle East Initiative predoctoral fellow at the Harvard Kennedy School. Chagai's core interest is in examining how institutions and the people within them shape intergroup relations in divided societies. He is also working on several projects examining the effects of scalable interventions for prejudice reduction, the electoral effects of conflict, the institutional origins of partisan polarization, and experimental methods.

  • Beliefs about minority representation in policing and support for diversification. Proceedings of the National Academy of Sciences of the United States of America Peyton, K., Weiss, C. M., Vaughn, P. E. 2022; 119 (52): e2213986119

    Abstract

    Diversification of police forces is widely promoted as a reform for reducing racial disparities in police-civilian interactions and increasing police legitimacy. Despite these potential benefits, nearly every municipal police department in the United States remains predominately White and male. Here, we investigate whether the scale and persistence of minority underrepresentation in policing might partly be explained by a lack of support for diversification among voters and current police officers. Across two studies (Nā€„=ā€„2, 661) sampling the US adult population and residents from a city with one of the least representative police forces in the country, individuals significantly overestimate officer diversity at both the local and national levels. We find that correcting these biased beliefs with accurate information reduces trust in police and increases support for hiring new officers from underrepresented groups. In the municipal sample, these corrections also cause an increase in residents' willingness to vote for reforms to diversify their majority White police department. Additional paired decision-making experiments (Nā€„=ā€„1, 663) conducted on these residents and current police officers demonstrate that both prefer hiring new officers from currently underrepresented groups, independent of civil service exam performance and other hiring criteria. Overall, these results suggest that attitudes among voters and police officers are unlikely to pose a major barrier to diversity reforms.
