Abstract

Previous research suggests that economic inequality has caused a wide range of negative societal impacts. However, little is known about how economic inequality influences prosocial behaviour as a socioecological environment determinant. In five studies (N = 62,342), we examined whether economic inequality reduces prosocial behaviour by decreasing interpersonal trust and the moderation role of interpersonal targets. Studies 1, 2a, and 2b showed that interpersonal trust mediated the negative relationship between perceived economic inequality and prosocial behaviour. In Study 3, we used data from the World Values Survey to explore the relation between inequality and trust and found that it was moderated by the closeness of trust targets. In Study 4, we demonstrated that economic inequality only reduced trust and prosocial behaviour towards strangers, but not among friends and family. Taken together, the current research shed light on how economic inequality undermines trust and negatively impacts prosocial behaviour among different targets.
