Spotting a liar is very interesting social experience. the most import thing is to know what to do after to confront that person!
here is few ways to help you out spotting one.
Body language giveawaysWatch for the facial touching. Discovered by the Spanish study, people who are uncomfortable being dishonest tend to cover their mouth or touch their nose when they tell a lie. This could be an attempt to hide micro facial expressions or perhaps due to the sudden heat rush.
Watch what they do with their eyes. While breaking eye contact in itself is not a clear indicator of lying – people often look away in order to concentrate or remember details – if there is a distinct change in a person’s eye-movements, rapid blinking, looking up or down for long periods while speaking it can indicate dishonesty.
Also if they suddenly become hyper-focussed on staring you in the eye, it could be an attempt to counter-act the looking away factor and convince you of the lie.
People who are lying often fidget more than those who are giving straight answers. Fidgeting is usually caused by discomfort or nervousness – both of which are symptoms of someone worried that they’ll be caught out for being dishonest. (Keep this in mind in job interviews. If you’re nervous, remember to keep your fidgeting in check. Worse than simply implying a lack of confidence – it could cause your interviewer to distrust your answers.)
Linguistic indicators of dishonestyThe Harvard study, Evidence for the Pinocchio Effect, tested people involved in business negotiations where trust was required and money was on the line. You can access the full details of the experiment here, but these were interesting findings:People who are lying tend to use a lot more words than people who are telling the truth, probably because they feel the need to convince the listener of what they’re saying, rather than just tell them something. Researchers also called this the Pinocchio Effect – as similar to Pinocchio’s nose – the length of the sentence grew along with the lie.People who told lies of omission – leaving out relevant information rather than outright lying – actually went the other way, using even shorter sentences and fewer words than people telling the truth.
People who told outright lies were believed more often than people who attempted to hide the truth through not talking about it. (So if you really need to deceive, you’re more likely to get away with making something up than with attempting to avoid the subject.)Liars swear more often than people who are telling the truth. (Note – in the job interview scenario – don’t swear either way, whether or not you’re lying.)
Liars used far more third-person pronouns (“him, her, it, one, they, their” rather than “I”) than people who were telling the truth – or lying by omission. Similarly they also used much more complex sentence structures. Researchers interpret this as an attempt to separate themselves from the dishonesty at the heart of what they’re saying.
