Crystal Shackleford

Crystal Shackleford is a psychologist in the Department of Psychology at Yale University whose research examines intergroup relations, stigma-based solidarity, and the social psychology of collective resistance. Shackleford has investigated how religious cognition shapes attitudes toward outgroups, including work on prosociality, dehumanization, and cooperation across religious divides in cross-cultural contexts including Fiji, Israel, and Palestine. Additional work addresses folk theories of gender, attitudes toward ethnic and religious diversity in the United States, and the motivational role of beliefs in human conflict. Current research interests include intergroup betrayal, political alliances, and resistance to ethno-nationalism.
