How to trick a polygraph

In today's world, there is a strong belief that the lie detector can not be deceived - it can almost follow the course of our thoughts. It is believed that the accuracy of the test on it exceeds ninety percent. Belief in this myth is beneficial to people directly working with polygraph. This trick makes it possible to psychologically suppress the subjects. And the companies that provide such services, the popularity of such checks provides a chance to earn good money. But still - is it possible to deceive the lie detector?

Naturally, in recent years, science has been improved, but the generally accepted accuracy of "calculating the truth" is far from the truth, because it does not exceed even seventy percent. This means that it is enough only to know some secrets that will help answer the question "How to deceive a polygraph?". Let's get acquainted with the main ones.

First of all, stop worshiping this miracle machine. Have not yet come up with a mechanism that can penetrate to your head and read your thoughts. The lie detector only records how your physiological parameters change when answering pre-selected questions. The main thing is that a person should believe in his own conscientiousness or inspire himself with it. Then the polygraph will perceive his answers as true. People who constantly deceive, and, as they say, do not blush at the same time, can easily pass such a test without even thinking about how to deceive the polygraph.

The day before the test, you can use a little alcohol. On testing, "hindered" reaction will prevent the polygraph from accurately assessing your answers. But do not overdo it with alcohol. Also, if a few days before the test your sleep was short, then you will not be able to assess the situation objectively. However, it should be noted that, in addition to the lie detector, you are tested by a specialist. It will not be difficult for him to visually recognize that you are very sleepy and listless.

To use the next method, fortunately, you do not need to take anything. You just have to concentrate on some abstract subject: a table, a wall or a window, and to answer questions quickly, without much thought.

You can also apply the following simple method. When you need to give the employee a positive answer, but this is a lie, forget about what the expert is interested in. Mentally ask yourself a question, to which you can say yes (for example, I am twenty-five years old, my name is Maxim, etc.). Then just sound your answer. However, in practice, such a method is usually more complex than in theory. Therefore, you should practice beforehand.

The slightest muscle tension will work in the right direction and cause the necessary changes (strong pressing of the toes into the floor, tight pressure of the tongue against the palate), but only one that the expert will not notice.

In order not to wonder how to pass a lie detector, before testing it will not hurt to moisten the phalanx of fingers with alcohol. Do not worry if the expert suggests that you wash your hands. Although the effect, of course, after this will be slightly weakened, this method will continue to work.

So, now you know the basic tricks that help to understand how to trick the polygraph. Finally I would like to clarify that even if at a meaningful level we imagine to ourselves that truth, which for some reason or another benefits us, our subconscious still knows the real truth. The discrepancy between your responses to reality can manifest itself in increased sweating, increased heart rate, and also the frequency of breathing. All such reactions of our body are fixed by the lie detector. Therefore, the most unerring way in which we will know exactly how to deceive a polygraph is a genuine belief in our deception. But, unfortunately, not every person is capable of sincerely accepting the invented lie for the truth.
