Ever since polygraphs became popular, some people have taken it upon themselves to try to fool them. Despite the fact that throughout history there have been people who have claimed that you can fool a polygrapherHowever, the truth is that this is not proven and it is practically impossible to do so nowadays.
Polygraphs have evolved over time to such an extent that they have become increasingly accurate and reliable. As a result, the chances of attempting to circumvent this device are virtually nil.
So, in case you have to face one and want to try to outwit it at all costs, you should know that it is very unlikely that you will succeed.
Why can't the polygraph be fooled?
Have you heard the saying "the body doesn't lie"? Well, this is very true and the polygraph uses this as a basis for detecting whether or not you are lying. You see, the polygraph is responsible for detecting physiological variations in the human body. This includes blood pressure, pulse, sweating, among others.
So, even if you try to fool the polygraph, the truth is that mastering your body in such a way that you can avoid these changes is very complex. Both the device and the interrogation are designed to prevent you from lying.
When there is a change, it registers it immediately and it is up to the person reading it to interpret it. While some people claim to have been able to get around it, the truth is that it may be due more to the person's misinterpretation than to a failure of the polygraph.
Myths about fooling a polygraph
Over the years, there have been a number of myths about "techniques" to fool the polygraph. The truth is that none of them have been proven, not to mention the fact that there are scientific answers as to why they don't work.
Below, we are going to talk very briefly about some of the most common polygraph myths today.
Use of sedatives before the test
This is one of the most classic myths and it is that, according to logic, by attending the test "relaxed", it is not possible to obtain an accurate physiological response. This is completely false, not only because there are still slight changes that the polygraph detects, but there is another factor to take into account and that is the experience of the tester.
If you attend an assessment sedated or drowsy, it will be noticed, so the test will not be taken in that state.
The use of pain
Another thing that many people claim works is the use of pain. This means that many people bite their tongue to generate pain during the interview. Others even talk about placing a sharp object inside the shoe.
This is not at all recommended, not only because inflicting pain on yourself does not work, but also because the test may take longer as there is no concise result.
Practising relaxation and meditation
Very similar to the first case we talked about, in this case, it is more difficult to achieve, as reaching such a state of relaxation that you can confuse a polygrapher is very difficult. And this is mainly because the pace of the interviews does not allow it.
No matter how much you practice or how much you document yourself on the subject, it is highly unlikely that you will be able to fool the polygraph. So, it is advisable not to try, because you will fail.
