Body language reveals a lot about you

Body Language Giveaways

Did you know that we’re programmed to detect when we’re being lied to or when information is being hidden?

Even before we hook someone up to a lie detector test we can have a very good instinctive idea about a subject’s probable innocence or guilt thanks to their non-verbal communication. What the body does is approximately five times more effective than the spoken word. Professional liars, con artists and cheating partners who may look to avoid displaying tell-tale signs will still reveal their deception because the sub-conscious mind responds to a question or thought before the conscious mind does, if only for a moment. A tightened jaw, a twitch or a dark look can be their undoing.

In that moment the person has no control over their non-verbal communication; it is invaluable when assessing people’s integrity. Data collected during a lie detector test calculates perspiration, respiration and other indicators to create a comprehensive suite of information. Evidence is analysed within context and the gesture patterns shown during a baseline test.

Some basic body language:

  • An open posture:  the trunk (chest) of the body is open and exposed. This posture illustrates friendliness and honesty.
  • The closed posture: The torso is hidden. hunched forward, arms and/or legs crossed. Clues that the subject is defensive and anxious.
  • Arms:Close to the body means the person may be trying to make themselves smaller, perhaps a confidence or defence mechanism; widened arms suggest that they are trying to be bigger, more of an impressive, dominant presence.
  • Hands on hips: In control of the situation, ready to start. Or an aggressive stance.

Even when a person isn’t speaking, their mouth can communicate true emotions.

  • Chewing on the bottom lip:Anxiety, uncertainty and fear.
  • Pursed lips: Tightening of the lips is an indication of disapproval or distrust.
  • Lip biting: People sometimes bite their lips when they are worried, anxious, or stressed.
  • Covering the mouth or face: Instinctively, a child covers their mouth when they tell a lie and may cover their ears, so they supposedly won’t hear anything they don’t want to. Adults often touch the face to conceal lies, exaggeration or uncertainty. On the flip side, shy and unconfident people may cover part of their face as a protective measure.

Remember the saying that the eyes are the window of the soul? They also unveil deceit.

  • Solid eye contact: When a person looks directly in to your eyes they are either interested and engaged or if the look seems to last for too long, this is threatening.
  • Breaking eye contact:A clear sign that the person is uncomfortable, lying, hiding something.  
  • Pupil size: The pupil dilates when a person is lying – and the light levels do not change.
  • Blinking: A natural reflex that speaks volumes; uncomfortable or distressed people tend to blink more and if a subject tries to manage their blinking to confuse us, this appears awkward, there is no rhythm.
