  • How do you pass a polygraph test?

    Q: How do you pass a polygraph test?

    A: A polygraph test can be passed by manipulating the body's response to control questions. A participant's lies are only considered lies when they register a higher response than control questions. The results can therefore be manipulated in a participant's favor if the participant is able to elicit a higher response to control questions than the relevant questions of the examination.
