Effects of interactional justice on egocentric bias in resource allocation decisions

Three studies demonstrated that interactional justice was able to attenuate egocentric bias, i.e., the tendency to regard a larger share for oneself as fair. Study 1, an experimental study of negotiation, showed that fair interpersonal treatment led to a smaller egocentric bias, quicker settlements, and fewer stalemates. Study 2 showed that fair treatment was related to a smaller egocentric bias in a real-life context. University students were more willing to accept a higher tuition fee and less willing to cut the salary of their teachers if the interpersonal treatment received from the teachers was more positive. Study 3 showed experimentally that in support of fairness heuristic theory, when the fair interpersonal treatment received could be attributed externally, its attenuating effect on the egocentric bias disappeared.
