Secrets to Detecting a Lie

Do you always tell the truth?

Of course you don’t and neither do I. Most people lie everyday. It’s not that they get out of bed and plot their lies, it’s more like people lie to smooth over situations, to ensure someone’s feeling don’t get hurt and to fit in socially. Most of these lies are pretty harmless.

But what about an employee, colleague or leader who lies about their practice, behaviour or specific situations? Would it be helpful to know if they are lying? I’m guessing . . . “Yes!”

I recently had the privilege of hearing a colleague, Traci Brown, give a presentation on how to detect lying . . . and I’m going to share some of her secrets with you.


Before I begin, remember . . .

Do not judge these behaviours in isolation!


To detect lying, you need to consider the entire situation and conversation. The following ‘secrets’ are considered additional tools to detect lying.

Ok, here we go . . .


Secrets To Detecting a Lie:

  1. The Body Cannot Lie!
  • When words are saying one thing and the body is saying another, remember the body tells the truth.
  • For example a nodding head means “Yes” and a shaking head means “No.”
  • When I say, “I like your haircut” and subtly shake my head – what do you think my true thoughts are?
  • When I say, “I would never call in sick to go skiing” while subtly nodding my head, what do you think the truth is?
  1. Mouth Cover
  • When people want to withhold information, they cover their mouth
  • It’s kind of like they are trying to prevent deceitful words from exiting their mouth.
  • It doesn’t matter whether one finger is used to cover the lips, or an entire fist, the meaning is the same.
  1. Neck Rub
  • When people feel scared, nervous or worried, they touch or rub their neck
  • Stressful circumstances prompt our brain to stimulate certain behaviours that are protective, pacifying and unique i.e. The neck rub
  • Women may also pacify by playing with their necklace which equates to the neck rub.

Ok, there you have it . . . 3 secrets to detecting a lie.

Use them wisely and use them in conjunction with the other information being offered in terms of conversation and behaviours.
