Self‐Reported Beliefs About Verbal Cues Correlate with Deception‐Detection Performance

In this study, we investigated whether people who hold more correct beliefs about verbal cues to deception are also better lie detectors. We investigated police officers and undergraduates' beliefs about (i) cues to deception via an open‐ended question and (ii) 17 specific verbal cues, after which participants were asked to judge the truthfulness of eight video fragments. Results showed that undergraduates and police officers still hold wrongful beliefs about nonverbal cues, but have better insight into verbal cues. Moreover, a better insight in verbal cues was related to an increased accuracy for identifying truthful statements, showing that verbal cues do drive credibility judgments to some extent.Copyright © 2017 John Wiley & Sons, Ltd.
