Lies are part of human nature. No matter how hard we try to be honest, we all lie - sometimes to protect ourselves or others, and sometimes simply for social acceptance. But is it possible to detect a lie in just two seconds? According to FBI consultants, the answer is "yes." While there is no single sign that will definitely reveal a liar, there are behavioral patterns and signs that can be identified if you know what to look for.

Facial and Body Micromotion: The Key to Lie Detection

According to Paul Ekman, a world-renowned psychologist who has worked with the FBI for many years, one of the most powerful tools for detecting lies is facial micro-movement. These are very quick, unintentional expressions that appear in a split second and reveal a person's true emotions. For example, if someone is trying to hide anger or fear, their face may experience micro-movement for a moment before the face returns to a "neutral" state.
