Ways to detect a liar


Deceptive behaviour has become so common in today’s world. Teens lying to parents, teachers and elders have trained them to be effective and ‘professional’ liars. This habit is usually hard to get rid of. Here we take a look at cues that indicate if a person is lying to you or not.

When you want to know if someone is lying, look for inconsistencies in what they are saying. They may seem nervous and blurt out unnecessary information that has no relevance to the topic being discussed.

Body language

Physical expression will be limited and stiff, with few arm and hand movements. A person who is lying to you will avoid making eye contact. Movements will be very impulsive and mostly unnecessary.


A guilty person will get defensive when questioned, while an innocent may get offensive. This is not an acid test however.

Emotional gestures

Timing and duration of emotional gestures and emotions are off a normal pace. The display of emotion is delayed, stays longer it would naturally, and then stops suddenly. Expressions are mostly limited to mouth movements when someone is faking emotions instead of the whole face.

Speaking too much

The guilty person may speak more than natural, adding unnecessary details to convince you. They are not comfortable with silence or pauses in the conversation. Words may be garbled and spoken softly, and syntax and grammar may be off.

Change of topic

Usually when you want to detect a liar, try changing the topic just to see his/her reaction. If the person is guilty you will see a sense of relaxation on their face.

These aren’t foolproof techniques to detect a liar, but research has proven that they work in most cases.
