Peer evaluation in self-managing work groups.

A series of 3 experiments with business students examined how a rater's relative performance affects peer ratings. In Study 1, with 36 groups consisting of 178 Ss, outstanding contributors were the most discriminating evaluators. In Study 2, with 39 groups consisting of 186 Ss, individuals rated their own performance as well as that of their peers. Once again, outstanding contributors were the most discriminating evaluators, and self-evaluations were higher than the respective ratings received from peers. In Study 3, with 12 groups consisting of 61 Ss, below-average and average contributors may have discounted their individual performance outcomes by making allowances for external factors that affected their contributions. Together, these studies indicate that self-other comparisons in a work group influence peer-performance evaluations
