ABSTRACT In this article we compare the accuracy of personality judgments by the self and by knowledgeable others. Self- and acquaintance judgments of general personality attributes were used to predict general, videotaped behavioral criteria. Results slightly favored the predictive validity of personality judgments made by single acquaintances over self-judgments, and significantly favored the aggregated personality judgments of two acquaintances over self-judgments. These findings imply that the most valid source for personality judgments that are relevant to patterns of overt behavior may not be self-reports but the consensus of the judgment of the community of one's peers.
