- Checks the Signs
What happens during a polygraph test is that the machine checks the signs that are show by your body. Unknown to most people, what happens when they are lying or making up stories is that their body exerts more effort. The process of exerting more effort is then made noticeable by the different vital signs such as your breathing, eye movement, heartbeat, sweating, and much more. When you tell the truth, what usually happens is that these signs just show normal numbers. However, when you tell a lie, you double your effort because you make up a story, instead of just relaying what really happened. Hence, your vital sign numbers go beyond the normal count.
Interpretation is very important because this is where the output of the entire polygraph relies on. It would surely be useless to have a very advanced polygraph, but the operator doesn’t know how to properly use it or even analyze and interpret the results. This is where human intervention comes in. Even though polygraph tests are all about the processes made by the polygraph, it still needs a human touch in terms of analyzing and interpreting the results. Just be sure that the person interpreting the results is unbiased and that he or she doesn’t have any hidden agenda in twisting the facts of the polygraph test.
To sum it all up, one can clearly see how effective, important, and reliable polygraph tests and polygraphs are. This is because these follow a systematic procedure. Surely, these polygraphs have already given justice to millions of people throughout the world.
