Data from a sample of government research scientists were used to compare the psychometric properties of pooled and consensus ratings of job performance. It was hypothesized that consensus ratings would possess less halo and leniency error and greater validity than would pooled ratings. The findings supported the halo hypothesis and partially supported the validity hypothesis. Given the severity of the “criterion problem” in validation research, further research was recommended to extend the generalizability of these findings to other performance appraisal settings.
