A lie detector test (or otherwise known as polygraph) was created to examine physiological responses to questions in order to establish whether the subject is lying or telling the truth. Many people, including National the Academy of Science, the US Congress Office of Technology Assessment, and the American Psychological Association are skeptical about the accuracy of the polygraph test. However, lie detector tests are still being used very often to interrogate criminal suspects, and they’re also used to screen employment applicants in some companies.

You might have heard that you need to answer all the questions honestly, but it’s important to know that lie detector tests are created to evaluate responses to ‘white lies’. Therefore, even truly honest people can generate a false positive on the test. Moreover, I’m sure there are people who would want to lie to the test without getting caught. The good news is, beating a polygraph test is not as hard as you’d imagine. But you can’t pass the test if you don’t understand its mechanisms and how it works.
