Myths About Lying Exposed


    Eye contact, body movement, and incoherence are not indicators that someone is lying, says Jason Voss, content director at the CFA Institute. Speaking at the CFA Society Toronto session ‘The Psychology of Deception: Fiction and Reality,’ he said studies across cultures, nations, and professions, including police officers, show most believe that signs someone is lying include gaze aversion, body movement, speech disturbances, and inconsistencies in statements. However, Dr. Maria Hartwig, associate professor at the John Jay College of Criminal Justice, said liars do not exhibit any of these tendencies. In ‘Detecting lies in the financial industry: A survey of investment professionals’ beliefs,’ that she conducted with Voss and D. Brian Wallace, of the Department of Psychology at New School of Social Research, she shows that few behaviours were related to deception and that those behaviours that were related to deception were only weakly linked. Instead, the only real way to detect if someone is lying is to have some information about an untruth and question them on it.
