Previous research has suggested that power undermines cooperation in social dilemmas. However, the story may not be so simple. Guided by recent findings that power heightens sensitivity to unfairness, we examined the moderating effect of distributive justice on the association between power and cooperation. Across two experiments, when treated unfairly, high-power (vs. low-power) participants perceived greater unfairness. Moreover, high-power (vs. low-power) participants behaved less cooperatively not only when they interacted with the offender who treated them unfairly (Experiment 1), but also when they interacted with innocent third parties (Experiment 2). However, high-power and low-power participants showed no difference in perceived fairness and cooperation when treated fairly. These findings shed light on the association between power and cooperation by suggesting the modulating role of distributive justice, and they remind us that researchers should take participants' personal sense of power into account when manipulating fairness.
