Lying makes most people panic, sweat, experience a faster heart rate and higher blood pressure. This makes them susceptible to the the polygraph machine or the lie detector, which looks for signs of such physiological alterations. However, if you learn how these devices work, you can beat them by lying with words as well as your body.
When taking the test, the device initially registers the baseline of your crucial signs. The examiner then tricks you into lying by asking as series of control questions that are not related to the issue they are investigating. Such questions include- Have you ever committed a crime? Have you ever lied to get out of trouble? Most examinees will usually answer ‘No’ to such questions to come across as honest, but the examiners assume that the answer to at least one question will be ‘Yes’. Chances are you have lied at one point in your life to get out of trouble. As soon as the examiner tells an obvious lie, the machine blips and puts a baseline which serves as a signature of that person’s lies.
So, how do you really beat the polygraph test?
Change your respiratory rate, heart rate, sweat level and blood pressure when answering the control questions. This sends the control lies off the charts and by comparison, the answers to the relevant ones, whether true or not will seem true. An effective method of ramping up your crucial signs when answering the control questions is pressing down on a thumbtack, or a sharp item in your shoe. The pain will certainly cause most of your vitals to spike and the response will most likely read as a lie. While this trick can be quite effective if properly applied, polygraph examiners have developed a countermeasure for it, the simplest being having the subject take the test barefoot.
When answering the relevant questions, it is crucial that you remain calm. Your mind should be at ease and you should maintain the baseline breathing pattern. Keep in mind that you are in control and not the examiner. Even if you produce a small response to relevant questions, you’ll have created bigger responses when answering the control questions and that clouds the final results.
The simple fact that it is possible to beat the lie detector is the reason why many strongly object to them. Some say that Lie-detector and polygraph testing is a procedure that’s primarily dependent on trickery and so, it has no scientific validity.
