Power is a psychological accelerator, propelling people toward their goals; however, these goals are often egocentrically focused. Perspective-taking is a psychological steering wheel that helps people navigate their social worlds; however, perspective-taking needs a catalyst to be effective. The current research explores whether combining power with perspective-taking can lead to fairer interpersonal treatment and higher quality decisions by increasing other-oriented information sharing, the propensity to communicate and integrate information that recognizes the knowledge and interests of others. Experiments 1 and 2 found that the combining power with perspective-taking or accountability increased interactional justice, the tendency for decision makers to explain their decisions candidly and respectfully. Experiment 3 involved role-based power embedded in a face-to-face dyadic decision-making task; the combination of power and perspective-taking facilitated the sharing of critical information and led to more accurate dyadic decisions. Combining power and perspective-taking had synergistic effects, producing superior outcomes to what each one achieved separately.
