The Kernel of Truth in Judgments of Deceptiveness

We investigated the relation between appearance-based impressions of honesty and individuals' willingness to engage in deceptive behaviors. The data reveal that people who were thought to look dishonest were more likely to volunteer to participate in research that was described as requiring deception on their part than were individuals who were perceived to look honest. The data are consistent with the predictions of a self-fulfilling prophecy model of social behavior, as well as recent research that documents a kernel of truth in appearance-based impressions. The results further suggest that naive judgments of deception are more accurate than has been supposed.
