Ingroup favoritism-the tendency to favor members of one's own group over those in other groups-is well documented, but the mechanisms driving this behavior are not well understood. In particular, it is unclear to what extent ingroup favoritism is driven by preferences concerning the welfare of ingroup over outgroup members, vs. beliefs about the behavior of ingroup and outgroup members. In this review we analyze research on ingroup favoritism in economic games, identifying key gaps in the literature and providing suggestions on how future work can incorporate these insights to shed further light on when, why, and how ingroup favoritism occurs. In doing so, we demonstrate how social psychological theory and research can be integrated with findings from behavioral economics, providing new theoretical and methodological directions for future research.
内群体偏袒——即偏袒自己群体成员而非其他群体成员的倾向——已有充分记载，但驱动这种行为的机制尚未得到充分理解。特别是，尚不清楚内群体偏袒在多大程度上是由对内群体成员福利优于外群体成员的偏好驱动的，还是由关于内群体和外群体成员行为的信念驱动的。在这篇综述中，我们分析了经济博弈中内群体偏袒的研究，找出文献中的关键空白，并就未来的研究如何纳入这些见解以进一步阐明内群体偏袒何时、为何以及如何发生提供建议。在此过程中，我们展示了社会心理学理论和研究如何与行为经济学的研究结果相结合，为未来的研究提供新的理论和方法指导。
