How to Detect a Lie

    Are you getting the whole truth and nothing but? The answer may be lying right in front of you.
    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.
    Did You Know?
    In a recent poll, 91% of Americans reported lying on a regular basis.

    You know, back in jr. high there was this one dude who told me he's all rich in stuff(for example he said he owned a Bugatti Veyron and that his parents were founders of some random company or organization). I felt like he was lying because I have never seen anyone drive around in a Bugatti around my place. If I ever see that guy again and he tells me some stuff about his "rich life" I'm gonna use this video just to see if he is lying, also thanks for the info in the video Howcast!

    Soo... I'm bad at eye contact but I always tell the truth *sometimes* I now just started wonder if people think I'm "always lying". I pay attention to people's voices when I speak to them and I can easily tell if someone is lying about something that they are saying just by their voices.

    And now everyone will think they detected a liar each time someone is being nervous, while confident liars never get detected. Plus people that have confidence while lying probably tend to lie more. If you don't know the person, you most likely do not know anything about their typical lying bodylanguage. I think analysing body language for lying signs can be very unecessary and misleading, unless you think someone's words doesn't make any sense, no matter how they are spoken.

    I can tell if someones lying without looking out for any of these things. I'm just a good judge of character. I grew up with alot of deceit and had to learn fast when I was being lied to or not as a matter of survival. You can't lie to me for a protracted time and get away with, I don't take anything as guaranteed without tangible proof, even from a lifelong friend.
