The Science of Deception

The science of deception explores how people lie or hide the truth, often through subtle cues like facial expressions, eye movements, gestures, or speech patterns. Researchers analyze these signs to identify inconsistencies and signs of stress or nervousness, which can indicate deception. Techniques like polygraph tests measure physiological responses, but they’re not foolproof. Advances in psychology and neuroscience also examine brain activity linked to lying. Overall, this science aims to understand how deception works biologically and behaviorally, helping to improve detection methods while recognizing that honest and deceptive individuals may sometimes exhibit similar signals.
