The accuracy of social perception relates to the connection between judgments people make of others' psychological attributes, and the reality of those attributes with regards to the people being judged. There are three slightly varying approaches to interpreting accuracy the: pragmatic, constructivist, and realistic approaches. Empirical research suggests that social perception is mostly accurate, but the degree of accuracy is based on four major moderator variables. These moderators are attributes of the: judge, target, trait that is judged, and information on which the judgment is based. The Realistic Accuracy Model (RAM) explains that these moderators are a result of the process for accurate judgment. The process of accurate personality judgment starts with the target revealing relevant information, which then must be available to a judge, who then identifies and uses it to form a final judgment.
