Comparing the accuracy of personality judgements by the self and knowledgeable others.

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