There are times when a woman asks if she looks fat in pants and to keep things smooth mostly the answer is No. this is a blatant lie and this is apparent, yet the lie continues. These are simple situations and do not cause any trouble, but there are situations featuring higher stakes that it becomes crucial to know if someone is telling a lie.


Fortunately, nowadays there are detecting signs to bring out the truth and it is also believed that polygraph is one such effective tool that it traces peoples mind. Thus, the notions of looking at eye and speaking directly are overruled as some are experts in maintaining a direct eye contact and diligently lie.

Here are few things to consider the next time if you believe someone is lying to you.



  • If they cover the mouth trying to suppress the lies said. Even a gesture of fake cough is deceitful.
  • Touching nose bottom. The chemicals in the nose tissue swells on telling lies as these chemicals cause a bit irritation that the lie telling person has an urge to scratch nose.
  • Rubbing eye is also an attempt of the brain to block the lie or deceit. Of course, here women will not try this gesture as it may smudge their makeup.
  • Grabbing ear or rubbing the backside of the ear. This also includes tugging the earlobe or bending forward the entire ear.
  • Fingers in the mouth are put as self-calming measure while lying. This is also done when people insert gum, pen or cigarette in their mouth.



Eye Contact: They hold the eye contact now while lying, yet fail in attempts after sometime and end up doing the opposite.

Pupil Dilation: Pupils of a person will dilate to four sizes.  Actually, this varies with lighting and so cannot be considered an effective way of lie detection test.


Blinking:  Normally, people blink per minute around six to eight times. However, a person lying will show an increase in the blinking rate.

Eye Movement: Research says eyes moving to left side up is to recall imagery, mid for sounds and down for self-talking, while eyes moving to right side up is to create imagery, mid for noises and down to recall emotion. Thus, a person moving eyes to right (that is your left) may be making something. Note these movements; it may help in detecting a lie.



  • Scratching neck is a sign of telling lie. This gesture shows uncertainty in a person.
  • Crossed arms denote the person creating a barrier with lies.


Open Palms: Innocent people quickly raise their hands up showing they are clean, but it is noted that liars are reluctant.
