How To Spot A Liar

Body language – How can you spot a liar?

It has a lot to do with instinct. We’re programmed to sense when there is something amiss and so when behaviour alters, or information doesn’t ring true, our brains raise a red flag. There are behavioural trends which a liar tends to follow because the self-conscious mind triggers non-verbal reactions which are beyond the subject’s control.

Did you know too that people have great difficulty relating lies backwards?  This is why X Three Surveillance’s investigators and law enforcement agencies often ask someone to make time jumps when telling their story. They may have repeated a lie from start to finish many times but their ability to lie from the end to the start to the middle to the start again is severely hampered by human biology.

When our investigators carry out an investigation we appreciate that more truth can be gleaned from non- verbal communication, even when we don’t have the subject we’re questioning attached to a lie detector machine. We take the situation and similar occurrences of gestures displayed to construct a pattern and a clear picture of deceptive behaviours. Pupils dilate when someone lies and as a rule, if the eyes turn to the right this means a lie is being created rather than a memory being recalled.

Be warned: Non-verbal communication has 5 times more impact than verbal responses. Liars will show themselves as liars, it’s impossible not to. The onus rests on the other people to detect the signs.

Instinctively, a child covers their mouth when they tell a lie. Similarly, if someone tells them something they don’t want to see or hear, like a scary puppet, bed time or a request to tidy their room they will cover their eyes or ears. This carries through to some adults but becomes subtler. Adults normally touch their face to conceal that they are lying, exaggerating or uncertain about the information they are speaking. Be careful with this that the person is not simply shy or lacking confidence in communication.

Facial expressions, even fleeting ones, can tell our investigators a lot more than people realise. An unpleasant thought will be reflected in the face no matter what the verbal communication given.

For example: “Do you have any grievances with Bob?”

Tightening of the jawline for a moment and then a broad, forced smile, “No, Bob and I have always got on well. Very well.”

Untrained interviewers might think that the jaw tightening was related to thinking of a response but isn’t the broad smile and the very positive statement at odds with this initial facial tightening? Bob created an unpleasant response unconsciously before the conscious mind had time to cover it.

Our investigators are trained to spot anomalies, evaluate whether they are talking to “professional” liars who practice how to evade detection and we know every trick in the proverbial book to throw doubt on a lie detector test’s validity. Several clients have tried. They don’t succeed.

If you think you have a liar in your midst, call us about a lie detector test or interview with them. We’re here to help.
