How to fool a lie detector? Revelations of a Ufa polygraph examiner

Is it possible to fool a lie detector?

There is no single answer to the question of how non-experts can deceive a lie detector. According to reviews from people who service the device, the program has perfect sensitivity and is able to detect any slightest desire to lie. This is due to the fact that our subconscious mind keeps a trace of events that took place in the past, so no matter what you try to think about, the subconscious mind itself will give a reaction. A lie causes a kind of conflict between the consciousness, which is trying to control the situation, and the subconscious, which is recognized by a lie detector.

Secret service workers who undergo special training can deceive a polygraph. There is an opinion that not only agents, but also certain categories of people are capable of outwitting a lie detector: pathological liars who themselves believe in their lies, and actors. Lawyers who have to deal with the polygraph believe that rumors about it are an advertisement for the device and a kind of psychological preparation of subjects for the procedure, and the result of the test largely depends on the level of training of the specialist reading the indicators.

Behavioral opposition

Behavioral opposition is the line of behavior of the person involved, aimed more at the specialist than at distorting the polygram recording. These include:

• inappropriate behavior (for example, a sharp change in mood from depression to excessive emotionality);
• taking control of the conversation, asking questions during testing instead of answering “yes” or “no”;
• evoking pity, simulating illness;
• charm, laughter;
• slow responses.

Questions related to haste and the desire to finish testing as quickly as possible are also signs of insincerity and they will not go unnoticed by the examiner, because The pre-test conversation always talks about how to behave when passing the test.

Where can I take the test and the cost of the service?

In almost every city there are companies offering lie detector testing. For example, in St. Petersburg it is the “Laboratory of Truth”. This service is not provided free of charge. Its cost depends on the reason for the application and varies from 4 to 5 thousand rubles: investigation of theft - 5,000 rubles, employment verification - 4,000 rubles. Muscovites can order the service at the Center for Applied Psychophysiology.

Depending on the reason for the request, the price varies, ranging from 3 to 6 thousand rubles. The most expensive studies are those of a private nature. For residents of other cities, the website Detector-online.ru offers an online lie detector service. In addition, there are several free applications that can be installed on your phone. With their help, gadget owners can take the test themselves.

The third method is to apply cosmetics to the fingertips that reduce the level of reaction, for example, talc or deodorants for sweaty feet. One of the most common methods is rubbing salicylic-zinc ointment into pre-steamed skin of the hands and fingertips. Rubbing with alcohol.

All of the methods described above are not suitable if the research is really serious (for example, when investigating a crime, terrorism) and you first have to undergo a blood or urine test for the presence of psychotropic substances.

Ways to fool a lie detector

There are several very diverse, sometimes naive, methods of protection against this device, described in the literature for specialists working with polygraphs. Among them are such as rubbing antiperspirants on the palms of the hands, armpits, and taking 5 aspirin tablets before the test. Real practice proves the low effectiveness of such methods. In addition to them, there are also ways to deceive the polygraph, which are usually divided into three types:

• Psychological – ways to concentrate on other situations (solving problems in the mind, reading poetry),
• Pharmacological – use of sleeping pills, psychotropic, stimulant drugs before the test,
• Mechanical – attempts to distract from the procedure by causing unpleasant sensations to oneself (biting the tongue, squeezing the sphincter).

The seventh method is not very suitable for modern polygraphs, but still deserves to be described in this article - physical impact on the body, the client causing pain to himself, which confuses the body's reactions. The nervous system reacts not to the question and answer, but to the expectation of pain, which also disorganizes the computer. There are some nuances in this method. Often the client's body is hung with motion sensors to exclude the possibility of him using such methods as putting a button in the shoe and pressing on it with his big toe or biting the tip of his tongue.

What questions are asked during the inspection?

Lie detector testing lasts from two to three hours with short five-minute breaks. During this time, the printer will be able to ask about a hundred questions. They are repeated periodically, which allows you to find out accurate information about the subject. The text includes questions that determine the presence of negative or illegal experiences: has the subject ever stolen, taken and is taking drugs, committed minor violations (has crossed the road in the wrong place).

In some cases, the printer is interested in his personal life: has there been any family betrayal? Overly frank and intimate questions are not asked during the interview. In addition, if testing using a lie detector is carried out when applying for a job, then they ask about the attitude towards management in general, towards others, towards a specific company, and towards maintaining trade secrets. Before asking tricky questions, printers offer to talk about their negative experiences without using equipment.

How to pass a polygraph without problems when applying for a job

Testing an employee applying for a job with a lie detector comes down to finding out his lifestyle, attitude towards his professional responsibilities, and ability to meet the requirements of the team. First of all, you cannot lie during testing, because a lie is perceived by the employer as evidence of dishonesty. In fact, the employer is more interested not in the fact of your past mistakes, but in your attitude towards them. How can a test subject fool a lie detector?

1. Do not take any medications, alcohol or drugs before the procedure. This step will be regarded as an attempt to hide the truth. The specialist will definitely note this in the examination report on the detector.
2. Get a good night's sleep.
3. Use the oxymoron method, the deliberate use of contradictory answers.
4. If questions are used that are incorrect, unclear, or that affect your interests, views, or beliefs, you have the right to refuse to answer them or you can ask to reformulate them during the polygraph test.
5. Don't try to hide the truth, answer sincerely.
6. The results of testing on the detector in many companies, with the exception of government agencies, are advisory in nature. The final word remains with the leader. Therefore, do not lose your composure and confidence in the successful outcome of the matter.

How to influence the test results

Several tips from polygraph specialists can help influence the results of a lie detector examination. Among them is breathing control. After a problematic question, subjects take a “breath of relief.” In addition, with the help of breathing it is possible to control blood pressure and heart rate. To learn this, use breathing exercises and yoga. Playing the fool will help you bypass the polygraph.

In this case, you should be extremely non-serious when testing on the detector. Due to frequent illogical answers, the lie detector will become confused and will not be able to determine the required calibration. To avoid being suspected of deliberately strange behavior, which will only cause a negative attitude towards your person, you must adhere to the rule of the “golden mean”. Acting skills will help to cope with the lie detector, thanks to which the test subject tries on the role of another person.

A long lack of sleep will help you bypass the polygraph, deceive it, and hide your true thoughts. At this time, the body is in a state of trance, reactions to questions will be insignificant, which will be shown by the result. But the most important recommendation is not to exaggerate the role of the polygraph, perceive the procedure on the detector as something ordinary, nothing insignificant in your life, and certainly not fateful.

False identity or memory reboot

Is it possible to fool a polygraph? Yes, with appropriate preparation. There are categories of people who can do this easily. Spies and scouts. They undergo lengthy training on how not to fail a lie detector test. The ability to “get used to” a role helps artists deceive the apparatus without much effort, and there are people who are so accustomed to lying that they no longer notice what is true or false. Recent research in the field of the brain and memory development has discovered a sensational feature of our body, which allows us not only to deceive a polygraph, but also calls into question the very existence of a person’s personality. It turns out that our personality is not stable, it is constantly in rewrite mode. As a result of this, many memories may change to others, but the person is sure that all this really happened. Thus, the easiest way to deceive the detector is to believe your own lies.

“This is a slightly different situation,” says Vladlen Statny. “When a person is being trained to try to fool a polygraph, he has two truths: his main life line, and the life line in which he must truly believe.”

Back in the 60s of the last century, American intelligence agencies conducted experiments to create a false human identity. The so-called “MK-ultra” project. People under the influence of drugs and hypnosis had their real memory erased and a new one installed. The man forgot everything that happened to him and was confident in the truth of the new memories. So, upon a certain signal, a simple worker turned into a superkiller and vice versa. Moreover, he really considered himself the way he was programmed. And not a single polygraph could determine the truth.

“The question is whether we exist at all as individuals,” says Ilya Martynov. - This is a very good question. Why does modern philosophy come to the idea that there is no personality? Namely because we constantly correspond. How can you be a person when the real you is not there? From there, from the inside, you don’t remember yourself!”

The detector is designed to record changes in pressure and heart rate in order to determine the veracity of the subject’s answers. To do this, sensors are attached to the human body to ensure that changes in physiological parameters are transmitted to the computer. Experts from the NLP Institute demonstrate how this is done. In preparation for the examination procedure, the polygraph examiner and his subject reveal some secrets of the lie detector, which you can learn about if you watch the video from YouTube:
