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

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.
