Economic Inequality Fosters the Belief That Success Is Zero-Sum

Ten studies (N = 3,628; including five pre-registered), using correlational and experimental methods and employing various measures and manipulations, reveal that perceived economic inequality fosters zero-sum beliefs about economic success-the belief that one person's gains are inevitably offset by others' losses. As the gap between the rich and the poor expands, American participants increasingly believed that one can only get richer at others' expense. Moreover, perceptions of economic inequality fostered zero-sum beliefs even when the distribution of resources was not strictly zero-sum and did so beyond the effect of various demographics variables (household income, education, subjective socioeconomic status) and individual differences (political ideology, social dominance orientation, interpersonal trust). Finally, I find that zero-sum beliefs account for the effect of inequality on people's view of the world as unjust. The article concludes with a discussion of the theoretical and practical implications of zero-sum beliefs about economic success.
