Who supports redistribution? Replicating and refining effects of compassion, malicious envy, and self-interest

Abstract

Debate over wealth redistribution plays a prominent role in society, but the causes of differences in support for redistribution remain contested. A recent three-person two-situation model suggests these differences are shaped by evolved motivational systems of self-interest, compassion, and dispositional envy. We conducted a close replication testing this prediction, all subjects were British, recruited from an online subject pool. Study 1 (N = 206) confirmed the roles of self-interest (β = 0.20) and compassion for others (β = 0.37), as well as a predicted null effect of procedural fairness. Dispositional envy was non-significant (β = 0.06). In study 2 (N = 304), we tested whether it was better to conceptualize envy as being two separate emotions, benign envy and malicious envy. A significant effect of malicious envy was found (β = 0.13) and no significant effect of benign envy (β = −0.06). Study 3 (N = 501) closely replicated this improved model, confirming significant effects of compassion (β = 0.40), self-interest (β = 0.21), and malicious envy (β = 0.15), accounting for one third of variance in support for redistribution. These results support the role of evolved motivational systems to explain and improve important aspects of contemporary economic redistribution.


The authors conducted three studies to test their hypotheses. In Study 1, they replicated the findings of a previous study that found that compassion, malicious envy, and self-interest all predict support for redistribution. In Study 2, they developed a new measure of envy and found that this measure also predicted support for redistribution. In Study 3, they found that left-political support was associated with higher support for redistribution.

The authors conclude that their findings support the hypothesis that compassion, malicious envy, and self-interest all play a role in shaping people's support for wealth redistribution. They suggest that future research should examine the relative importance of these three motivational systems in different contexts.

Here are some additional key points from the article:
  • The authors propose a model of wealth redistribution that is based on three motivational systems: compassion, malicious envy, and self-interest.
  • They conducted three studies to test their hypotheses.
  • The findings of the studies support the hypothesis that compassion, malicious envy, and self-interest all play a role in shaping people's support for wealth redistribution.
  • The authors suggest that future research should examine the relative importance of these three motivational systems in different contexts.
