Do Polygraphs really work? Yes.
  • Employee Polygraph Protection Act of 1988 bans the use of polygraph tests for pre-employment screening because they work.
  • New Mexico allows polygraph results to be submitted as evidence in court.
  • The FBI and CIA use the polygraph
  • Used on telvision shows: Moment of Truth, and Maury Povich
  • In episode 109 of the popular science show Mythbusters, they attempted to fool the polygraph by using pain to try and increase the readings when answering truthfully (so the machine will supposedly interpret the truthful and non-truthful answers as the same.) They also attempted to fool the polygraph by thinking happy thoughts when lying and thinking stressful thoughts when telling the truth to try and confuse the machine. However, neither technique was successful and the examiner Michael Martin correctly identified each guilty and innocent subject. The show also noted the widely held opinion that, when done properly, polygraphs are correct 80-99% of the time. [1]
  • It was widely reported that OJ Simpson repeatedly failed polygraph exams administered by his defense team. [2]
