The Reliability of Lie Detector Machines
There are a lot of people who are asking whether lie detectors are really that reliable. The answer to that is that it depends. It is important to know that lie detector tests are only allowed by the court to happen if both parties agree to it. If one of the parties does not agree to a lie detector, then it is not allowed by court to happen.
Knowing the Mechanics of a Lie Detector Test
These lie detector tests are also inadmissible in court. One of the interesting things about these is that there are already a lot of people who can attest to the test’s unreliability, as they themselves claim to have beaten it. If ever a complainant wishes to use a lie detector test to see if you are telling the truth, and you think that it will only cause trouble on your part, you have the privilege and right to not let it happen.
Variation from Person to Person
Not all people remain calm when they undergo a lie detector test. Different people have their own different variations in terms of calmness and nervousness. It is because of this that makes lie detector tests really challenging. What happens during a lie detector test is that the person’s vitals are measured out. Any spike in any of the vitals of the person would then mean something.
Spikes tell that the person might probably be telling a lie. The person’s blood pressure, breathing, and heart beat are all measured, as these are one of the many vital signs in one’s body. Yes, each machine has its own variation, and that is where one can see the difference. But all in all, every lie detector machine follows the same.
