ABSTRACT
Burdens and rewards are inequitably distributed across various social group memberships (e.g., by race, gender, ethnicity, SES). While considerable research has examined the processes underlying intergroup cognition, relatively less research has considered how these mechanisms contribute to bias in morally-relevant intergroup decisions. This chapter reviews the limited behavioral and neuroscientific research on intergroup decision-making related to trust, cooperation, and fairness. This review shows that group membership affects these decisions and often contains moral dilemmas. The overlap in the neural antecedents implicated in intergroup impression formation, moral reasoning, and decision-making is also reviewed to derive a new Intergroup Moral Value Computation Model. Together the reviewed research highlights the importance of considering the flexible integration of ingroup vs. outgroup partner characteristics and social norms to understand moral judgments and decisions. We conclude by discussing remaining questions and future directions for intergroup moral decision-making research.
