The Hollywood movies put some idea to us that the prepared person can cope with any task, brave heroes are not afraid of either fighting sorties, or checks on a polygraph because precisely know how it is possible to deceive the lie detector. But whether these receptions are available to ordinary people or to dupe of smart electronics by all means it is necessary to be trained in a special school?
How it is possible to deceive the lie detector?
For a start it is necessary to understand that a polygraph – the difficult device equipped with the mass of the sensors fixing even the minimum changes of indicators. Some devices can even estimate electric activity of a brain. But at all technical complexity the method is not strictly scientific as a lot of things depend on a human factor. Our organism can react with increase in pressure or increase of pressure for various reasons, and not just because of desire to lie. Therefore the huge role will be played by qualification of the expert who will interpret the results which are written down by the device. That is why to think of how to deceive the lie detector, costs, only if an inspection on a polygraph is carried out not by the best expert. That is, at communication with law enforcement agencies it will hardly turn out to count on the hitroumnost, and here the shameless employers considering themselves have the right to obtain the most personal information, will hardly be able to distinguish a lie. The fact is that the rare company is capable to hire the employee who not only is capable to work with the device, but also is an experienced psychologist. So, most likely, you should deal with the pseudo-specialist who will not be able correctly to make questions at the right time to cause reaction, and on the basis of the received records at all you should not dream of the correct conclusions.
How to outwit the lie detector?
There is a lot of options of counteraction to such pseudo-printers. One of the most obvious – it is good to think over the lie. If to answer quickly and rather surely all questions, then reactions of an organism will not give a lie. But there are also other ways to deceive the lie detector. One of sensors reacts to sweating of palms which has to increase in a stressful situation. To exclude this factor, in day of testing wipe all phalanxes of fingers with medical alcohol. It has the tanning effect therefore hands will sweat much less. It is not necessary to wash them this day any more. Of course, the expert will try to change position of sensors, can also ask you to wash up hands. In the latter case the effect will be reduced, but completely will not disappear.
Be trained to take a sharp breath so that it was imperceptible from outside. You breathe so at the answer not each question, then the device will define the increased reactions throughout all testing. If the polygraphologist is surprised to it, tell that you just are afraid of the procedure.
If you quite quiet person, then can try to show the lowered reactions to all questions. For this purpose you need to relax and present yourself not the participant of the events, but the viewer watching not the most fascinating movie. It is also possible to drink soothing for half an hour before testing. It will help to give the lowered reaction to all questions too. If you have to tell about drug intake, then you say that you drink it constantly according to the recommendation of the doctor.
To deceive the lie detector it is possible to try to cause the increased or reduced reaction at the answer to control questions. For this purpose accelerate or slow down breath, step on the button which lies in a boot, try to submit the weakening picture, etc.
It is important to remember that your interlocutor is not among your friends, and it will be obligatory to tell a lie, trying to confuse you. So you should not trust him as far as charming the polygraphologist would not be. Also other option is possible, some try to intimidate tested, for this purpose the room situation, stories about supersensitivity of the device can be used, it is not necessary to trust it too. Also you should not give the culture concerning the principle of operation of the lie detector, do not tell that were interested in this question.
