Hello dear blog readers! The lie detector is not able to read a person’s thoughts, it is only able to detect the slightest changes in the body that occur under the influence of micro stress. And today we will try to figure out whether it is possible to deceive a lie detector if you learn to control your body systems or carry out thorough work with the subconscious?
Device and principle of operation of the device
The lie detector captures various characteristics of our body, which change if a person lies. People have long noticed these features, and even in ancient times they tested suspects. For example, they put rice or rice flour in their mouths and forced them to eat. It was believed that with strong experiences, the amount of saliva is significantly reduced, so the process of swallowing the culprit will be in jeopardy. Or it was necessary to touch the red-hot sword with the tongue, and if the person was alarmed, accordingly, salivation slowed down, and he received burns.
There were many such methods, but all of them did not take into account one thing — a person could simply worry about the upcoming test, thus falling under the threat of accusations. Therefore, over time, all observations were taken into account and a polygraph was created, which, using sensors, captures:
- Flashing
- Pulse
- Sweating
- Change in pressure
- Volume or voice change
- brain activity
- Micromovements of the body
These are the main indicators, but there are polygraphs that cover more characteristics, such as changes in the direction of movement and pupil sizes. But the most important thing in passing the test is the very qualification of the person who will interpret the values of the indicators. After all, it is very important to correctly formulate questions that will not cause a surge of emotions, which can very likely be mistaken for untruthfulness.
It doesn’t matter if you were tested for employment or to identify your involvement in a crime, its most basic rule is voluntariness. That is, you have every right to refuse for purely personal reasons. The only nuance is that refusal can only strengthen the belief in your guilt. Often, in order not to frighten off qualified workers, they are tested after they have taken shape and worked for some part of the time. To avoid this, check with employers in advance at interviews whether they practice this method.
The methodology itself consists of the following steps.
1.Screening
To do this, it is necessary to study in detail all the materials that caused the use of a polygraph test. After that, the specialist will understand how and what exactly should be asked. Sometimes, in order to eliminate the risk of subjective assessment, a whole team of specialists is engaged in this.
2.Preparation
The operator talks about how the device works and calibrates. That is, it reveals exactly how the subject’s body reacts to lies and how it behaves when it tells the truth. To find out, you have to answer a number of questions in the negative, even when you have to lie. Usually biographical data is specified, that is, the name, place of residence, and then, for example, it will sound: “Are you human?”, And you have to answer “no”.
When a response occurs in the body, the polygraph examiner will fix it, and then, for verification, he may offer to guess a number or a card, which he will guess based on changes in the body’s indicators, when he lists the probable answers in turn and calls exactly the one that was conceived. Calibration has two goals: to set up the device and to show the subject that it works without failure, and there is no point in distorting the truth.
3.Testing
The second stage is the testing itself. It usually takes about three hours in time, and in order to exclude incorrect interpretation, the question to which there was some kind of reflex will be asked several times, only in a different form. I said, the polygraph cannot read minds and recognize lies, it only captures the minimum processes that occur as a reaction in the human body, and which are not noticeable at first glance. You can sit with a stone face, not expressing any emotions, but not everyone can control the pulse rate.
Sometimes it happens that a person has tension not because he is guilty, but based on the very attitude to a situation. For example, a man is suspected of stealing in the workplace, and during the passage of the detector, he shows a very bright and strong reaction when asked directly whether he stole at this job. Such a situation can cause a storm of indignation based on his personal beliefs that stealing is not good and shameful, and a lot of anger and resentment, because he was a responsible employee, but this was not appreciated. Therefore, he could fail this test, but experienced polygraph examiners can reformulate or even have a conversation in order to find out about the true reasons for such a body recall.
4. Interpretation
The specialist looks through a series of answers, during which the device recorded changes, and conducts a control conversation on them, after which he can realistically assess the situation and issue a conclusion.
Walkthrough Recommendations
- Before starting testing, raise a topic that concerns you, ask a specialist about your fears so that he can dispel any fantasies by explaining the nuances and working moments.
- If you know that you react very strongly, remembering some moments from the past, and you understand that this can affect the results, be sure to talk about it.
- A polygraph examiner is a person who is not interested in your guilt, or vice versa, he is a third person who is important to do his job well, so you should not withdraw into yourself, be afraid of him, consider him an “enemy” or even try to seduce in order to change the results. Just be open, as the result will depend only on you.
- No matter how trite, but answer truthfully, at least you yourself must believe in your sincerity.
- Do not rush to answer, always listen to the end. But at the same time, do not delve into memories, otherwise you can only harm yourself. For example, there were no cases of theft for you, you are an honest person who will never take someone else’s. But suddenly they remembered that in childhood they stole a typewriter from a friend, and that’s it, consider that you failed the test. Just mentally isolate yourself from the current situation.
- Answer only when you understand the essence of the question. There are situations when, not quite understanding what is at stake, a person answers, and then thinks. The polygraph does not forgive this. In which case, you can repeat again if there are difficulties.
- It may seem difficult, but it is very important not to get hung up on what is happening, try to relax. Explore in advance at home your fantasies of what exactly causes tension and fear, especially if you are not threatened with punishment for committing a crime. You will be checked by a live person who is also experiencing excitement.
- You should definitely have a good rest the day before, because you will need a lot of strength to be focused and included in the process. Still, three hours is a long time.
Tricks
Professionals who work with this device claim that it is not at all easy to outwit it, but there are still daredevils who try to check it out. There are options such as taking alcohol the day before, which will simply dull the reactions. Or take a sedative. It is also recommended to cheat in this way: to give reactions that are completely opposite in order to knock down the calibration settings. Only now the complexity arises, external equanimity is easy to maintain, and it is almost impossible to influence internal processes.
To elicit a reaction when speaking sincerely, experts recommend using the sensation of pain by putting, for example, a button in the toe of your shoe and pressing it with your finger if necessary. These tips can help only in one case — if you have a beginner in front of you, who himself has just studied the device device. Experts interrupt attempts to meditate instantly, as they notice a stopped look and a changed, detached intonation.
Do not experiment, the possibility of retaking is not always given, and the testing itself is expensive, so very few companies can afford it when hiring employees. Those who lie, but at the same time sincerely believe in what they say, can successfully pass it. Pathological liars have a great chance, they distort the truth so often that they themselves then do not understand the boundaries between fiction and reality.
There are some essential tips that can make it easier for you to pass the «interrogation»:
- To abstract a little, concentrate on an object in front of you, for example, some kind of strip on the wallpaper, and try to imagine that what is happening, for example, you are dreaming, and you are watching the process from the side. This will help not to react so closely and in general, help to relax a little.
- In the case when you want to deliberately increase the physiological reaction a little, try to think about what makes you angry, or, for example, try to remember the multiplication table or some kind of formula in order to strain your brain at that moment, thus causing tension .
- Imperceptibly micro-movement of the muscles can be achieved by touching the tip of the tongue to the palate, or resting the tips of the toes in the toes of the shoe, the effect will be the same as from the buttons that cause pain.
