Sages Aristotle once said: the lies of private grounds, the real you for no reason.

On this sentence can think about it this way: you have a reason to lie, lie in order to achieve a purpose exists; to tell the truth you do not need any motivation, because it is the same. Due to a strong purpose, lie looking very difficult: to make people believe is the truth, lying before careful to not leak flaws lie carefully; when you want to tell the truth you don't have to charge what trouble, have something worthy to say directly to said.

In short, a lie is a trouble, tell the truth is much more easily.

I'm afraid that everyone experience across both of this distinction, but more and more from scientific evidence also indicates true.

The truth lies in different brain areas

The proof lies need brains of the best evidence comes from Brain Science, a functional brain imaging studies show that people are telling the truth and the lie of brain activity.

First, the active area, both have their preference, the truth brain areas including frontal, temporal lobe in 4 brain regions that lie brain areas including frontal, temporal lobe and edge system 7 brain regions. Followed by the number of active area, which is more conducive to the description of the problem lies in brain regions of quantity advantage inescapable that lie some really more laborious.

On the analysis of specific brain region lies a more persuasive.

When to lie not lumajiao, often very concerned about his own words, ready to analyze and judge, and make adjustments to justify, but the truth is usually not necessary so carefully, so the charge of rational thinking and language memory associated frontal brain regions are located in thetemporal lobe is lying is more involvement.

Of course, sometimes lie not needed careful consideration, such as the boss suddenly appear behind you, see you playing the game, so concerned about the progress of the work and asked: how to? you switch the screen on the side, side quickly answer: fairly smoothly.

This is improvising, blurted out, didn't go through too many thoughts. But this time the situation in the brain and the truth is there is still a very big difference, the difference is that although your batting an eye, but inevitably anxious, the result is responsible for the emotional edge system highly excited, truth and therefore exposure.

The results of this study is still very rough, in future, deal with more style, more categories of lying way more surveys, in-depth exploration.

Even so, these results are still of great importance, its significance is not only to prove that lie you sure you want to spend, but also to lie detection provides a more reliable method. To lie, the brain to do more work and this is not to the person's will as to transfer.

Lying and small independent

From behavioral research confirms brain imaging findings: when people are lying and not, as we previously thought will unconsciously blinked, touching nose, scratching his head, restless, and make all sorts of little tricks, but tend to be obedient decorum, quiet.

This is explained and compared to the usual, lie to harder to think, because when we fall into thinking tends to reduce body on the occasion of the action, in order to maintain the spirit of dedication.

In order to disguise the lies, liar will consciously controlled blink frequency, so it fell to normal levels, even as a question of Minnesota's eyes open, calm as usual.

But we still have a simpler approach to the identification of the person opposite lying without using cumbersome instrument. Would be to observe his hand. Liar in needs action, usually with exaggerated hand gestures to conceal the truth, such as the extension arm or used rhythmicity of gestures to emphasize a point.

Former landmark case took place in April 2003, the then Minister of Iraq News Sahaf retreat in Iraq Army General, arm, hand and effectively toward the front, he told the media: "Baghdad is safe.

" The latter is a representative of the United States President Bill Clinton, he has been tame and waving, full of rhythm hand, each syllable firmly said:" I have not experienced with Ms. Lewinsky sex! "

Visible, lying not easy not only to consume a large amount of brain power, there will be actions too cause risk of muscle injury.
