Effects of social value orientations on fairness judgments.

The authors assessed the impact that social value orientations--prosocial (i.e., concerned about outcomes for both oneself and others) versus proself (i.e., concerned about one's own outcome only)--had on fairness judgments in a non-negotiation setting. The results indicated that prosocials generally formed fairness judgments in a manner suggested by equity theory: Given the same input as a comparison other, they saw an equal outcome as fairer than a favorable or unfavorable outcome. The fairness determinations of proselfs, however, tended to follow the tenets of self-interest theory: Given the same input as a comparison other, they saw a favorable outcome as fairer than an unfavorable outcome. Contrary to self-interest theory, proselfs did not find a favorable outcome fairer than an equal outcome. These findings indicate that social value orientations differentially affect the evaluation of outcome information in the formation of fairness judgments.
