Lying. Everyone does it at some point. Children begin lying around age 3, according to the American Psychology Association in a January 2008 study. No matter where they are born or their race or education, children learn that lying avoids consequences. And they get better with time, improving their ability to tell plausible lies.
But, of course, some people never quite grow out of the habit. They become lifelong habitual liars, professors in the fine art of deception.
Lies can be destructive, destroying trust in our marriages and personal relationships, destroying even our life's savings if we fall victim to the wrong lies. Because we can be harmed by the lies of others, in business and in our personal lives, we all have an enduring critical need to learn how to detect when someone is not telling the truth. "Did she lie?" "Is he lying to my face?" "Can I believe them?"
But even though we all have a need to tell when someone is lying, the truth is, most of us are just not very good at it. Numerous studies conducted over 3 decades have revealed that most of us can only tell when someone is lying about 50- 55% of the time. An even money gamble. The same odds as a flip of a coin.
So, we are babes in the woods when it comes to matching wits against the polished skills of expert liars. What is the Number One tool people use to tell when they're being lied to?
The answer comes from a 2006 study conducted by 91 scientists in a global initative on lie detection published in the Journal of Cross-Cultural Psychiatry. Scientists asked more than 2,000 people from nearly 60 countries, "How can you tell when people are lying?"
And, it turns out that, whoever we are or whatever slice of the world we inhabit-- whether you are a citydweller in a skyrise apartment in Manhattan or London or a near naked bushman in a goatskin hut in Australia-- we humans have remarkably all arrived at the same coping tool for detecting lying.
We all think liars can't look us in the eye. As the scientists concluded" “[There are] common stereotypes about the liar, and these should not be ignored. Liars shift their posture, they touch and scratch themselves, liars are nervous, and their speech is flawed. These beliefs are common across the globe. Yet in prevalence, these stereotypes are dwarfed by the most common belief about liars: ‘they can’t look you in the eye’. "
"This is the most prevalent stereotype about deception in the world," says Charles Bond of Texas Christian University in Fort Worth, who led the research project.
But is this true? Are shifty eyes the tell-tale mark of a liar?
The answer, sadly, is just the opposite. Studies have shown no correlation between shifty eyes and lying. This common stereotype, like many others about liars--they clear their throats, they shift their weight--tell you nothing about whether a person in front of you is lying.
Fortunately, there is a growing science behind the pursuit of lying. What are the true telltale signs of lying?
Micro-Expressions
The face has two kinds of muscles. Some of them are under our control--we use them when we smile, grimace, talk. But others are not under our conscious control. These involuntary muscles are the ones that produce what are called "micro-expressions", movements so tiny that most of them go undetected. Ticks are an example of a micro- expression, as are sudden flutters of surprise, fear or suppressed guilt.
A study by psycholgist Paul Ekman of the University of California found that 90% of liars show 35 different micro- expressions and other gestures when they lie.
