Ingroup Favoritism in Cooperation: A Meta-Analysis
Research-assisted source review
- What it supports
- Cooperation favoured in-groups by d=.32 overall; the estimate was d=.19 without mutual interdependence and d=.42 in social dilemmas.
- Where it may not transfer
- Tasks, identities, cultures and publication conditions were heterogeneous. Cooperation differences do not by themselves identify hostility, unfair intent or a safe interface intervention.
