Groupy versus Non-Groupy Social Preferences: Personality, Region, and Political Party
通过实验复制了部分人在收入分配中表现出群体内偏袒而多数人没有的现象，并探究了人格、人口统计和政治因素的相关性，发现大五人格、性别、教育和政党均无预测力，但政治独立者更少群体偏好，去工业化地区或深南部共和党人则更多。
This paper replicates results that some people, when allocating income, are “groupy” and discriminate between in and out groups, but many show no such bias. The paper explores psychometric, demographic, and political correlates. In an M-Turk experiment, no “Big Five” personality trait relates to this individual difference. Gender, education, and political party are not predictive. Political independents, however, are more likely to be non-groupy, and participants in deindustrialized counties or Deep South Republicans are more likely to be groupy. The results indicate (i) psychological notions of personality do not capture this heterogeneity and (ii) groupiness might relate to political and social contestation.
