Computer-aided Credibility Assessment by Novice Lie-Catchers

History is replete with men and women who have caused a great deal of harm and damage through skillful deception. Even though effects of deceptive actions have garnered much recent attention, deception is not a new problem. Researchers have been fascinated with deception and with credibility assessment for centuries, yet humans perform poorly when assessing credibility (Bond et al. 2006). This work presents a prototype system that unobtrusively identifies kinesic and linguistic cues that may indicate deception. This research explores improving assessment accuracy through merging improved human capabilities with system use. System use was found to significantly improve assessment ability. Training in credibility assessment was found to weakly improve assessment ability.
