Common Misunderstanding about Liars

I read this in a forum.

"This is how to detect someone lie.

Notice the person's eye movements. Contrary to popular belief, a liar does not always avoid eye contact. Humans naturally break eye contact and look upwards when remembering something. Liars may deliberately make eye contact to seem more sincere. Liars also tend to blink more often. A typical right-handed person tends to look towards their left (your right) when remembering something that actually happened (remembered images, sounds and internal dialogue) and towards their right or downwards (constructed images, sounds and kinesthetic sensations) when they're making something up.

Be sensitive to the person's emotional expression.

Timing and duration tends to be off when someone is lying. Emotions can be delayed, remain longer than usual, then stop suddenly. Likewise, they might not match appropriately with verbal statements. And, as with smiling, facial expressions of a poor liar will be limited to the mouth area.

Pay close attention to the person's reaction to your questions. A liar will often feel uncomfortable and turn their head or body away, or even subconsciously put an object between the two of you. Also, while an innocent person would go on the offensive, a guilty person will often go immediately on the defensive."
