The accuracy-confidence correlation in the detection of deception
A meta-analysis was conducted of research on the relation between judges' accuracy at detecting deception and their confidence in their judgments. A total of 18 independent samples revealed an average weighted accuracy-confidence correlation of .04, a relation not significantly different from zero. However, confidence was positively correlated with judges' tendency to perceive messages as truthful, regardless of the actual truthfulness of the messages. Judges were also more confident when they really were rating truths compared to when they were rating lies. Also, men were more confident than women, and judges who had a closer relationship to the message sender felt more confident in their judgments of truths and lies. Methodological and theoretical explanations for these findings are discussed. Copyright © 1997 by Lawrence Erlbaum Associates, Inc.
