When we tell a lie we must build a whole base and history around it to be able to sustain it and make it credible.When this happens we require our brain to work at its maximum capacity, is this situation favorable for our intelligence or not?
The more liar the smarter?
A study by researchers at the University of California seems to indicate that the more liar a person is also more intelligent.Having to create a whole story to make a lie sustainable makes the brain must work harder so that no detail is left out , and thus prevent the inventor from being exposed.
According to this research people who often lie very often have a greater amount of dad of white matter in the frontal lobe of the brain.That increase in white matter allows the person to be able to relate different ideas and thoughts that have no relation to each other with more easily, which makes them smarter than those who do not lie so regularly or whose lies are not so elaborate.
What betrays a liar?
Other research points to the gestures that tend to betray liars, such as the University of Michigan , whose researchers discovered what are the needs that arise in a person who lies to release stress.
In this sense, the researchers explain that when a person lies experiencing a deep stress , which translates into an increase in heart rate, dilation of the pupils and increased adrenaline.The active liar's brain the body's defenses, which makes all its senses are on maximum alert.
Cognitive dissonance is also another factor experienced by people who lie.This dissonance appears because of the clash that exists between the two versions of a fact, the first is the truth and the second is the lie.
The University of Michigan came to the conclusion that when someone lies loudly feels the sudden need to brush your teeth .On the other hand, when the person lies through a written form such as an email, cell phone or letter, he has an urgent need to wash his hands.
The University of Texas also conducted various studies regarding this issue.The conclusion is that there is an intimate relationship between lies and Gastric arrhythmias.In addition, the person's temperature also changes, his pulse accelerates and the less skilled can present excessive sweating.
