A lie has no legs and the truth will come out?
You most likely heard of those idioms people use to brighten up their language with and use to teach you (a lesson) as well. One of them is honesty is the best policy.
Whoever came up with this one and is it true?
You might say it is but if you like it or not it's not true.
In reality, we are hardly able to recognize a lie. Even a bad liar gets away with it. The problem is in principle we think people do speak the truth. We adjust to it they do which means we love to believe lying true the teeth are rare. We love to think people are honest and speak the truth therefore not lie because it's easier for us to cope with. That is why we do not like to hear those who reflect their doubts or dare to say "he's a lying bastard".
The Twente University in the Netherlands did experiments to figure out all about liars and the ability to recognize them.
They were eager to find out who speaks the truth and who lies. If a lie has no legs and the truth does come out. If it pays to be honest. Can we recognize a liar? Are there signals, is there a certain behavior?
Touching your nose while speaking, not able to sit still, avoiding looking at someone while speaking are seen as proof of telling a lie
Again this turns out not to be true. It's even the opposite of it. Most people are not capable of recognizing a lie at all.
How to recognize a liar?
That will be a hard one if we refuse to believe people do lie and dare to lie straight into our faces. To those who really want to find out the truth, the only way is to ignore the idioms of "wisdom", leave out all prejudices, and count on the fact that those who are most dear to us are the biggest liars of all (unfortunately this is proved too).
