#16  Lies, Tells, and Body Language with David Allan

Loading player...
Body language, deception detection, and the signals liars can't hide.

Can you really spot a liar? In this fascinating episode of The Laundromat, Dawn Pretorius sits down with internationally renowned body language expert David Allen to separate fact from fiction in deception detection. From eye movements and nervous gestures to interview techniques used by law enforcement, David explains how behavioural analysis can reveal discomfort, concealment, and potential deception. He shares real-world cases involving criminal investigations, false reports, and leadership environments, while exploring why body language is never about a single "tell" but a pattern of clues. The discussion also examines the role of AI, the importance of establishing behavioural baselines, and how investigators, compliance professionals, and business leaders can use these skills to ask better questions and uncover the truth.
