The answer may be lying right in front of you. To complete this How-To you will need: A good ear Good eyes A healthy skepticism Step 1: Watch their hands Watch the suspected liar's hands. Body language studies show that people tend to touch their face and scratch their nose when they lie. Step 2: Follow their eyes Follow their eyes. Liars tend to blink a lot and don't maintain eye contact. Step 3: Note their words Note their words. A liar will skip contractions—saying "I did not" instead of "I didn't"—and avoid pronouns, using someone's full name instead of "he" or "she." Step 4: Check their smile Check their smile. People who are telling the truth use many facial muscles, but liars smile with just their mouth. Step 5: Note their posture Notice their posture. Liars tend to keep their body posture closed (by folding their arms, for example). They may also unconsciously put an object between you, like a cup of coffee. Step 6: Pause before responding Pause momentarily before responding; if the silence makes them uncomfortable, they may be lying. Step 7: Note the details Pay attention to details. If they provide more information than necessary, that's a bad sign. People tend to be overly specific when they're making something up. Step 8: Change the subject Change the subject. If they seem relieved, that's probably a red flag that they've been lying straight to your face! Step 9: Teach your liar a lesson What you do from here is up to you. It may be smart to file your knowledge away for future use. However, if you're noticing a trend, it might just be time to teach your liar a lesson. Thanks for watching How To Detect a Lie!
