A bit about the polygraph

Hundreds of scientists investigate the nature and mechanism of human lies, but only a few specialists can tell if they are 100% lying or not, and for absolute accuracy it is necessary to be able to work with several technologies to detect fraud (distortions, fantasies, etc.).

Despite the fact that there are quite a lot of firms and schools advertising polygraph examiners in Russia, most of them do not give special guarantees in accuracy, and try to offer a probabilistic conclusion.

Moreover, the probability of conclusions can be not only not indicated, but also be veiled very low (unreliable). Today we very often encounter the fact that the polygraph method is used completely incorrectly and despite beautiful advertising signs the customer as a result remains (deftly or rudely) deceived, and we also have a large number of slandered people due to false polygraph examiners.

Essentially, Polygraph is a technical tool for conducting instrumental psychophysiological studies, recording respiration parameters, cardiovascular activity, electrical resistance of the skin, as well as other physiological or other parameters, followed by presenting the results of recording these parameters in analog or digital form.

As a result, the polygraph gives us a printout of the graphs (reactions) of the researched on certain issues. At the same time, one of the mistakes of polygraph examiners in interpreting the results is precisely connected with incorrectly asked questions. Currently, according to the statistics of our reviews and consultations, such an error reaches 50% of the causes of an “incorrect polygraph”.

It can also be noted that most people and novice experts do not understand that a lie detector is not a magical device that accurately determines whether a person is telling the truth or not. This is just a technique with sensors that attach to a person to receive reactions through the channels: respiratory, galvanic-skin and cardiac. Everything else is the skill, professionalism and honesty of the polygraph examiner. It is his correct questions, psychological competence, and reading the polygrams of the reactions of the researched that determine the accuracy of the conclusions.

A lie detector simply determines a person’s reaction to a particular question (a reaction can be emotion, stress, perplexity, irritation, etc.) and not necessarily a hoax. And if the polygraph examiner does not have the proper education and work experience, then the results of his research can be completely incorrect and based only on the data of the device. Here also a lot of mistakes occur, including due to the fact that a person is sweating or

got nervous, but all these and other manifestations do not indicate that the researched is lying.

Today, apart from diligent juniors, out of all kinds of schools come out, and obvious ignoramuses with crusts of specialists, and both of them in practice (at work) can “blame” a completely uncomplicated person for a particular act or crime. As a result, the subject can be fired from work or doomed to problems with law enforcement agencies.



As a positive factor, it can be noted that the polygraph method is wider and more confidently striding across Russia, there are more conferences and seminars, a lot of professional literature has appeared.

A polygraph in forensics helps determine the likelihood of a person being involved in a crime. The polygraph is increasingly used in judicial practice, in the investigation and inquiry, in the business sector, in the selection of personnel for work to work.

In conclusion, I want to note that the polygraph method is able to give clear answers to many questions (research topics), if this method is used correctly. As well as increasing the accuracy of a professional polygraph examiner, the use of additional technologies (methods) for identifying lies and truths, determining fiction and facts helps.

In Russia, there has been a bad tendency towards a decrease in the level of general education and education. People really stop reading books. People really stop writing text with a ballpoint pen. Their attention is delayed only in pictures or watching videos, in which mental work is minimal. And not comparable, for example, with memorization or memorization. Education is part of human culture. After a poor education received initially, a person decides to become also a polygraph examiner. Courses of polygraph examiners pursue profit and often do not provide basic knowledge to the extent that a specialist needs in practical work. So it turns out that the ignoramus who gets into his fate with a "biting little hand" falsely accusing him or falsely justifying him. A good education is now becoming the privilege of rich people, but we are well aware of the reluctance people learn with money. That is, there is a wave of polygraph examiners ahead who will frankly dislike their work and at the same time issue fateful verdicts to people. What is the way out of this? I think we need to change the training system for polygraph examiners. The first is to weed out those who by their qualities mental, psychological and others cannot become such a specialist. Second, Muscovites and St. Petersburg coaches of the polygraph need to change the training system by dividing it into 2 levels. The first is on-line lectures. The Internet is accessible practically in all corners of Russia. And the second stage is the training of young people in the real work of a specialist. It can last from two to five days. You need to be able to infect them with your example. And the third is to think over payment schemes for equipment that were available to most working lawyers of psychologists and engineers (it is from these specialties that people come to polygraphology). Then money will not have a decisive influence on falling into the profession. So we can expect that this "wave" about which I wrote above will not catch us off guard or will bypass it altogether.

One more important remark. Any polygraph examiner knows that there is a direct connection between the skin-galvanic reaction and the mental abilities of a person. When I wrote about a decrease in the level of education, one cannot think that it concerns only polygraph examiners, it applies to everyone, including the clients of a polygraph examiner. It is no secret that our school graduates, especially those with church education, cannot add 2 double-digit numbers in their minds. Such is their real level of knowledge! Things are no better with university graduates. Does this mean that soon the RAG channel should be canceled as having lost its relevance in recognizing the lie? I have been in the profession for more than 20 years and why so far our scientists have not said which axons of the brain affect this channel through which we remove information from a person? Is it time for scientists, along with practitioners, to set up the experiments that the Americans made 100 years ago, but at the present stage of human cognition? Maybe then the answer will come what to do with those who prefer the computer perception of information to what really develops the amount of memory and other important processes of the human brain.

Thank you, my dear colleague.
I read both of your posts with pleasure.
Although, of course, all this is very sad, then what are you writing about.
