Truth or Tale? How Construal Level and Judgment Mode Affect Confidence and Accuracy in Deception Detection

Abstract

Abstract Previous research has indicated that individuals typically perform quite poorly in discerning truths from lies, and that confidence in judged veracity is not predictive of objective accuracy. In this experiment, we investigated the joint influence of construal level and judgment mode on detection accuracy and confidence. Participants (N = 161) watched eight videotaped true and false statements while adopting a high or low level of construal, and received instructions to detect the deceptiveness of the statements either before (online judgments) or after (offline judgments) watching the videos. Contrary to our predictions, construal level and judgment mode did not influence detection accuracy independently or interactively. However, low level participants were less confident when making judgments offline as opposed to online, whereas the confidence of high level participants was unaffected by judgment mode. Implications for deception detection research and practice are discussed.
