How to cheat the lie detector: 7 ways

The mysterious invention called the polygraph has made a real revolution.

With its help it was possible to determine when a person is lying, and when telling the truth.

It would seem, with his appearance in prisons, there will no longer be innocent convicts.

Asked the suspect: "Have you committed a crime?" And close the case if there is a guilty person in front of you.

But, as it turned out, the polygraph is not ideal, because he accuses some of the most nervous and unstable people of lying unjustifiably, whereas people with steel nerves know how to deceive the lie detector and avoid justice.

It's not that hard to really get around this finger.

Moreover, many people have succeeded in this.

Will be successful for you if you learn more about the lie detector.

How did the lie detector come about?

Such categories as "truth" and "lie" have always interested humanity.

Shamans, priests tried to find out the truth with the help of some rituals, the priests - through confession, the ancient Chinese - with the help of a handful of rice placed in the mouth( the rice should remain dry if the person is innocent), etc.

The story of the modern lie detector looks like this:

1. In 1877, Angelo Mosso invented a tool that measured the pressure.

   He worked simply: if a man lied, his pressure increased.

2. Focusing only on increasing pressure, worked and forensic specialist Cesare Lombroso.

   He owns one more discovery: he found out that the suspects-liars have a faster pulse.

3. The first polygraph, which took into account several indicators at once and was attached to a person, was designed in 1933 by Leonard Keeler.

3 interesting facts about the lie detector

For a long time I thought that the appearance of a lie detector on light is in itself a very interesting fact.

But when you study this question in more detail, you realize how many incredible things happened during different tests.

Here are the 3 most interesting facts about a polygraph, in my humble opinion, naturally:

1. If the first detectors endured their verdict based on only a few indicators, then modern devices take into account almost 50 indicators: pressure increase, sweating, pupil size change,ligaments, subconscious reactions, etc.

2. Polygraphists themselves insist that the polygraph is not called a lie detector, because this device does not determine so much, the person says the truth or not, how many notes the change in the state of a person when answering various questions.

   It is because of this that the polygraph is so often mistaken.

3. The scientists who are engaged in the study of lies, against testing people on this detector, because they consider the results obtained with its help, too inaccurate. Who can deceive the lie detector?

   
   Not everyone can deceive the lie detector. More precisely, anyone can try, but there are those who can do it without much effort:

   1. To Scouts and spies - they are specially trained for such, and not for one year.
   2. Pathological liars - these simply do not understand the difference between truth and deceit.
   3. Sociopaths - they react to many things differently than normal people, so they just confuse the lie detector.
   4. To children, because they can sincerely believe even in fictitious things and old people staying in marasmus.
   5. Professional actors - they used to lie a lot, pretending to be other people, so they can easily deceive the car.

   But, even if you do not belong to any of the above categories, you can still outwit the polygraph.

   You can achieve this by understanding how the device works.

   Go to several tests and analyze everything you see.

   Real people who managed to deceive the lie detector

   
   Those who work on a polygraph with a heat prove that it is impossible to deceive the lie detector in any way.

   Like, even a yogi who knows how to stop his heart can not cope with such a difficult task.

   Ha!

   I can give you at least three examples, when people managed to deceive a polygraph, and not once.

   1. American Floyd Fay was not a pay-boy, but the murder that wanted to hang on him, did not commit.

      It was the polygraph test that was decisive for the conviction and imprisonment of Floyd.

      He was so angry with a stupid typewriter that he decided to take revenge on her.

      Fay began to teach other prisoners how to deceive the lie detector.

      And what do you think?

      23 of 27 of his students succeeded.

   2. Aldrich Ames was considered a valuable CIA employee, had an impeccable reputation, good track record.

      During the years of service, he repeatedly passed a test on the lie detector and each time he was asked whether he was a double agent working for the USSR.

      "Of course not!", Ames responded indignantly and the polygraph confirmed that this was a true answer.

      Only after many years it turned out that Aldrich always managed to circle a miracle device around his finger, and over the years of service he sold many secrets of the KGB.

   3. Kim Philby's name is familiar to those who are interested in information about spies.

      British intelligence received a crushing blow when it learned that one of its leaders was an underground communist and for decades served the interests of the government of the USSR, not Her Majesty.

      Yes, no James Bond films can not wash this shame!

      What is most interesting - Kim Philby was tested on a lie detector, which he managed to deceive, taking Valium - a sedative.

   2. Sedatives.

   3. Abuse of something harmful on the eve of ( alcohol, light drugs), which will reduce your sensitivity.
