In this study, we examined the effectiveness of using indirect methods to detect liars. College students viewed a video in which half of the people told some lies and half of the people were entirely truthful. Participants were either asked to detect the liars in the video or they were asked to identify people in the video whose behavior, mannerisms, or speech changed. Participants using the indirect lie detection method of looking for behavioral change were more accurate in their categorizations of liars and nonliars than were participants who were directly and explicitly looking for liars.
