Looking Closely At What Lie Detectors Can Do

A lie detector test works when a polygraph detector starts measuring the respiratory rate, the amount of perspiration on the fingertips of the person, and also the heart rate. Then there is an examiner which checks the results of the test, they also study the differences of the spikes as well as the results of the person’s behavior. When you are under the test, you are hooked up on with wires as well as tubes then connected with the lie detector machine. You will be facing a series of questions by the examiner and you will also be asked to tell your own version of the story.

What you need to know is that it’s not the lie detector which decides if you are telling the truth or not, it will be the examiner and what he or she has deduced from the results. Everyone has their own different reaction when subjected under the lie detector which is why it is not wise to depend on the wires alone. The questions are designed in a way to help find the truth from the person. The questions would usually be general in nature, which people would have a hard time saying no to, as well as asking controlled questions.
