Does a Polygraph Really Dectect Lies?

I really think about what I want and show if I am calm. When someone tells lies, they must always react. They must be completely mad to lie and feel calm. When you lie, will you laugh, sweat, and will your heart speed up? On another resource web site, we point out that only completely mad people should be able to exceed the polygraph test. It said that the average person did not have the opportunity to sit down and not lie on the polygraph examination without becoming nervous.

Nielsen wrote it in a review called "scientific evidence of a lie detector test" and announced it to a journal "liars" of a lie detector. Instead, Nielsen wrote that the polygraph measures how people respond and react to the problem, and how resilient people react to them. Mr. Nielsen said the process of analyzing the results is complicated. The examiner will compare the answers to the related questions with the control problems they expect. Nielsen said that it is a similar idea to test students at the beginning of the school year and end the progress. Based on these comparisons, the examiner uses statistical analysis to determine the probability that the candidate is lying.

Polygraphs are often called polygraphs, but they do not recognize lies. Certain physiological lie responses have not been confirmed and the likelihood of being present is low. Instead, it records the physiological activities associated with the awakening of the autonomic nervous system. 10 The response it measures is not specific to fraud, nor are they always generated. The purpose of the polygraph inspector is to establish a psychological setting for the candidate. This increases the likelihood that the specific problem observed is caused as a result of fraudulent reactions. The theory includes threats and emotions, but is it due to fear of losing into a lie, conditional reaction to lies, positioning of emotions, increased cognitive processing necessary for deception, or by other mechanisms It is still unclear whether something is wrong.
