The Science of Lying

The science of lying involves understanding how the brain and body react during deception. When we lie, the brain activates different areas responsible for decision-making and control, often increasing cognitive load and making liars more mentally strained. Physiological responses, such as increased heart rate, sweating, or changes in speech patterns, may also occur due to this stress. Modern techniques like lie detection analyze these subtle signs, but they are not infallible. Essentially, lying is a complex interplay between cognition, emotion, and physiology, reflecting the brain’s effort to create and maintain falsehoods.
