#1 Eye Contact
Rumor always is if you cannot make eye contact with somebody while talking to them, you feel too bad saying it to their face. If you notice somebody focusing on something else or a different object nearby, chances are that person is lying about what he is telling you.
#2 Distraction Levels
When somebody is either standing or sitting in front of you and you suspect that he/she is lying, pay attention to the way in which they are speaking to you. When somebody is too focused or appears to be interested in something else, the chances that they are saying lies to just end the conversation with you is extremely high. Pay attention to their body language and how they are listening/talking to you.
#3 Body Language
Pay attention to the person you are speaking to. If that person displays a negative body language, the likelihood of that person putting all of their meaning and effort into the conversation is highly unlikely, and that person would have no issue in ending the sentence or conversation through lying, or saying what the person wants to say. Having a negative posture while discussing is a great indicator that
#4 Level of Cooperation
According to a professional psychologist named Bella M. Depaulo, “Liars are noticeably less cooperative than truth-tellers.” If somebody seems to have to have zero interest or ‘pleasantness’, chances are they will be more likely to lie. People who make negative statements towards whatever that topic is are more likely to lie their way to finishing a project or getting out of a situation.
#5 The Way He or She Talks
Do you ever notice when the person’s voice level changes, whether it be volume or pitch? When this happens, psychologists believe it could be a result in lying, which affects the nervous system, thereby raising and lowering the pitch in which that person is talking.
#6 Size of The Person’s Pupils
The size of the person’s pupils can be correlated with lying due to the nervous system, just like pitch and volume of speech is. Look into the person’s eyes to see if their pupils have excessively dilated; it is an extremely common phenomena amongst liars.
#7 Ask the Question Again
If you think somebody is lying to you, ask the question again. Chances are if they were lying, the person will make a mistake and tell you something different than the first time. This can be tested by simply saying, “I’m sorry, but what did you tell me a few minutes earlier, I forgot?” A simple question like this is not rude to ask, and can be used to determine if somebody lied to you earlier.
#8 Constant Fidgeting
Moving around in a seat, tapping your pencil, or tapping your fingers; these are all examples of fidgeting that normal people occasionally do periodically. Whether it be nerve, excitement, or anything else which results in the rapid movement of legs or arms or fingers, fidgeting is also correlated with lying. If a person is lying, he or she may be moving or tapping unnecessarily while they are lying.
