How economic success shapes redistribution: The role of self-serving beliefs, in-group bias and justice principles

In the face of economic inequalities, redistribution of wealth is a key debate for society, and understanding the reasons why individuals may support more or less redistribution can inform this debate. Here we investigate the mechanisms by which experiencing success in a task decreases the support for redistribution of the wealth generated by the task, such that overachievers favor less redistribution than under-achievers. In a laboratory experiment, we replicate this effect and explore how it that may be mediated by an in-group bias, or by changes in individuals’ principles of redis-tributive justice. Critically, both in-group favoritism and self-serving adjustments of justice principles partially accounted for the effect of status on redistribution choices. Our study thus sheds new light on the various ways by which economic experience affects support for redistribution.
