Someone who says something false or incorrect (intentionally) despite knowing it is not true is called a liar. People lying usually want others to accept that the lie is the truth. They can have many purposes for lying.
Various Types of lies
Distortion
Getting rid of or adding details to a fact. If a specialist says that "The tablet is safe in little amounts," a drug company can twist it and say, "The specialist says the tablet is safe."
Deception
Fooling someone into believing something with many lies across a more significant time.
Exaggeration
Assuming that something is higher or smaller than it is, for example, someone says, "I am starving to death," when one is hungry but far from dying, or someone says he is vital as a crocodile!"
White Lies
Telling a little lie make human feel good if it does not harm anything or anyone. For example, a girl says she likes what another girl is wearing even though she does not; it is a white lie.
Lying can only be done on reason. If a person says something that is incorrect and does not know that it is incorrect, that person is making a mistake and not lying.
How To Catch A Liar?
1. Body Language
When you talk with someone, see his hands; if he is lying, he will try to hide or touch his hands with each other. His hand will move unintentionally, and he will try to control it. He will talk with bend shoulders.
Check his facial tics. A genuine emotion will commonly symmetrically influence both sides of a person's face. When a person smiles, look for facial symmetry, as this will show real emotion. If a person uses only the mouth muscles rather than their entire face, he is simply trying to lie.
2. Facial Expression
The best way to catch a liar is by reading facial expressions. If he is biting his lips repeatedly or pushing his lips into his mouth while talking, his nose hole becomes large, sweating while talking, so be informed, there is something hidden. The sudden pinkish color that appears on the face is also a sign.
3. The Way Of Talking
The liar person mostly forgets the story. If he tells you the same story again, the story will be somewhat changed. He will try to get him separate from the story, saying that "who cares," "How he can do it," I can't even imagine," etc.
4. Face And Eyes
A liar person usually takes his hand to his face or eyes unintentionally. It happens because of natural reasons. Even he does not know about it. The brain is not accepting the story, but you try to hide it by covering your face or eyes with your hands.
5. Swearing Again and Again
Studies and research reveal a liar person swears again and again. He tries to prove his lie to the truth by saying that I am speaking the truth.
6. Inconsistencies
If you doubt someone that he is lying, give notice to any inconsistencies in his story. It is a simple lie pointer that is used by investigators and in courtrooms. It's challenging to keep up with a lie, particularly when asked to repeatedly go over the circumstances. The liar will more than likely slip up and eventually tell on themselves for lying.
