“Dishonesty is an integral part of our social world, which influences both financial, political as well as personal relationships.” So a study with the title “The brain adapts to dishonesty”, the researchers from London published in the journal “Nature Neuroscience”.
The researchers, however, had already in autumn 2016, a study published around a Central question: does frequent lying the brain? “In many cases, it starts with a small lie, but quickly escalated it,” said Tali Sharot of University College in London. Their Thesis is that With every lie, the brain dulls a little and get used to it, to tell the truth, as you get used to violent images, if you see them often enough.
The bolder the lie, the greater the profit
Their theses, the experts verified with an Experiment in which Volunteers should be mutually lie to. The people was shown a glass full of coins, each with a different level. Then the protagonist (Person A) had to inform their Partner (Person B), who was in another room, how much money is in the vessel. In this case, the brain was examined with a functional magnetic resonance imaging (fMRI).
The Partner (Person B) got, in turn, only a low-resolution, blurred image of the container to see, and had to rely, therefore, on the testimony of Person A is.
There were several variants: Either both of them got a correct answer, the same reward, in other cases, one was rewarded, if you lied to the other participants aware of it. It was found that The bolder you lied to his Partner, the more you are rewarded.
The first time you lie, you will feel the worst
An interesting finding was: In the round, in which both participants benefited from the lie always on a similar Level. You could get, however its own advantages, and were lying with each progressive round. Some people lie in the first round, an additional pounds, in the end they stopped at eight pounds.
The brain Scans showed later that the first lie fired the Amygdala. It is also regarded as the “fear center” of the brain. With each falsehood, the response was weaker. The effect was so clear that the Team was only able to detect on the basis of the activity of the Amygdala, how big is the next lie would be, writes “New Scientist”.
The conclusion: “If you’re lying to its own advantage or to cheat, you feel bad,” says Sophie van der Zee of the University of Amsterdam. “But if you do it again and again, disappears this feeling at some point, and it is more likely that you’re doing it again.”
Frequent liars are more difficult to transfer to
The Experiment provided valuable insights. “This shows the risk of frequent, small falsehoods,” explains Sharot the “New Scientist”. Notorious liars are, therefore, usually better to transfer heavy. Because the Amygdala is aroused when practiced liars are less and many symptoms, which otherwise holds out, are hardly to be discovered – such as sweating or evasive glances.
