It is a common thing for people to lie, but it is also a common thing for other people to find out if they are lying or not. More often than not, psychologists conduct experiments on liars and find out what they do when they lie. So, how to tell if someone is lying to you?

These range from simple hand movements to a quickly rising temper. Once these signs are noticed, it becomes very easy for anyone to catch a liar.Researchers have shown that all liars have a few common traits that they share. All of them have tiny actions that will give them away.

Typical Signs:

Usually, people tend to get nervous when they lie and this is what most people look for. They search for fidgeting and anxiety in the person they suspect of lying. This is not an accurate way to catch the liar because most of the liars are never nervous. They are confident and know they can get away with it, so this tactic becomes moot.
Looking for nervousness in a liar can end in vain, but there are a few things one can do to find out if and when the person is lying.

Small gestures:

A liar will often cover the place they believe is vulnerable. Their hands will move to their mouths as they talk or go over their throats, abdomens or other parts that they think are susceptible. This is a psychological reaction where the brain automatically protects the body from the person they are lying to, considering them a threat.
Lying is added stress on the brain; the person who is lying is suppressing the truth and making up another story. This causes the brain to focus on the lie and it generally tends to leave the person standing still or shuffling their feet without knowing it.

It is hard to lie because it makes people think. They often tend to focus on the story and leave out details and names of places, fearing that they might get them wrong or mixed up somewhere along the story.

Because of this, they keep repeating things or saying common nouns instead of proper nouns.
When a person is lying, their eyes tend to shift a lot, not looking at the person being lied to and not being able to control involuntary things like blinking or keeping a steady breathing pattern. As a result the liar will tend to get breathless and blink a lot while they tell their made up story.

A way to catch a liar is to ask them to tell their story backwards or name the people and places they went to. The liar will become even more nervous as the on spot thinking will have their brain pushed into over drive and they will snap at the party being lied to.

The rise in temper is a sign of the stress they are under which tends to expose their lies.
