Body Language "Experts" | Can They Actually Detect Deception?

This video attempts to answer the question: Can body language be used to detect deception or reveal other details about thinking, feelings, or behavior? There are a number of so-called body language “experts" who claim that body language reveals information unconsciously and believe they have the ability to decode this language. These individuals claim that they can read posture facial expressions and body movements to uncover information that's not communicated verbally. A number of gestures have been ostensibly been connected to specific motives or behaviors: closing one's eyes, scratching the neck, touching the nose, covering the mouth, not making eye contact, making too much eye contact, rate of speech, crossed arms, and blink rate. Although many of these body gestures have meaning, they can't be used to reliably detect deception.
