On the accuracy of ratings of personality by strangers.

Past studies in person perception have shown unexpectedly high correlations between targets' self-ratings of personality traits and ratings of those targets made by stranger judges. Possible reasons for the apparent accuracy of strangers' ratings are examined, including personality judgments that are based on (a) the perceived social desirability of targets, (b) known sex-linked base rates of behavior, and (c) the inevitable presence of valid personality cues in the typical stranger rating study. A computer simulation study is then described that illustrates that a relatively small number of nonrandom accurate judgments among many random judgments can produce substantial overall correlations between self-ratings and stranger ratings. The data of the study provide some clarification of past empirical results of both stranger and acquaintance ratings of personality.
