Be a Lie Detector

Most of human's life time are spent by lying, even lying to the others or lying to their own self. However mouth (Verbal Language) can tell the lies, body language always tells the truth. There are some unique body reactions when people are lying.

Nonverbal communication, such as Body Language, reacted by subconcious mind. Because of when someone is not telling the truth, their nonverbal behavior speaks volumes.

There are some ways to spot a liar :

Liar can't talk fluently when they are lying

You know, such as too much using "ummm....", "...", "err..". And they always trying to misdirect the topics of the conversation.

Eyes never lie

"Eyes are speaker in trust". When someone try to lie, they always try to avoid eye contact. Another thing a liar will do is look down rather than up. Studies have shown that when we're trying to recall something we look up (and to the right I think) whereas if we're lying we look down whilst we think what to say next.

Never stop moving, and hard to calm down

Look at their body movement! Never stop of making a movement. Look at their hands! Their hand wringing/palm rubbing; it's as if they're trying to wash the lie off themselves. Touch their nose frequently, grab their ear, try to cover their mouth.

Collar Pulling
A Liar pull their collar sometimes. Pulling collar can means "It's hot here" or "Oh My Gosh! They will know the truth!"

Moaning

A person who lies will generally be more downbeat about what they're saying with negative statements and moaning rather than being upbeat and cheery.

A question that never be answered

Some questions which you asked to a liar, won't be answered. Because of the liar afraid of they will blow their lie if answer your question.

NO ONE CAN LIE TO THEIR SELF!
