When growth mindset backfires: The effect of the perceived malleability of groups and utilitarian motives on support for collective punishment

Collective punishment (CP) is deemed unfair because it sanctions group members who are not responsible for the wrongdoing. However, CP may be driven by utilitarian motives, aiming to deter other group members from committing offenses. This research investigated whether individuals’ inclination to support CP for utilitarian reasons is influenced by their belief in the malleability of groups (their belief that groups can change; a growth mindset). In Studies 1 and 2, we assessed utilitarian motives and manipulated participants’ perception of group malleability. In Study 3 , we assessed perceived group malleability and manipulated motives for justice (utilitarianism vs. retribution). Across these studies, the dependent variable was participants’ support for CP. Results consistently showed that utilitarian (more than retributive) motives increased support for CP, specifically among participants who believed in the growth mindset of groups. We discuss the relevance of these findings for social justice and growth mindset literature.
