  Adam keeps playing gleefully with balls and what&apos;s basically a simple metal tube, nothing more.<br>Jamie: &quot;Yeah, I know it&apos;s fun, let me get back to work.&quot;<br>That&apos;s probably the most succinct characterization of the two possible..

  When they talk about the studies on the polygraph. They fail to mention that the lower figure would mean two out of ten being wrongly convicted if they used this in court. Why are the figures not more consistent if it&apos;s so good?

  What the lie detector thing was missing, is the &quot;penalty for a false positive&quot; - i.e. in real life, if it&apos;s wrongfully telling somebody did something wrong, they have consequences to fear. So their truthful answers will also be given under stress. In this case, a false positive would have no consequences, so the answers are much more relaxed by definition.

  By the way, Kari and Tory never took that bus trip. The producer made it up to stress them out. They talked about it on the Mythfits podcast

  How do they know the polygraph hasn&apos;t been beaten? Surely the whole point of defeating a lie detector is to not get detected beating the detector.

  Polygraphs (I refuse to call it a &quot;Lie detector&quot;) measure stress responses. Which physiological stress is CORELATED to lying, but not a guaranteed indicator.

  Polygraphs are not &quot;Lie Detectors&quot;<br><br>Hence why they&apos;re not admissible in court

  It always disgusts me how the polygraph people lie about the accuracy &amp; efficacy of their stupid pseudoscience machine, and about the related scientific research. The fact of the matter is they <b>need</b> people to believe it works, in order for it to have the intimidating effect that the operators rely on.<br><br>The process needs to intimidate people in order to put the subject under stress in order to break their composure and force mistakes and inconsistencies in their answers. A &quot;lie detector test&quot; is less about the stupid machine, and more about the interrogation techniques of the operator.<br><br>In theory, you might think, if someone is telling the truth they shouldn&apos;t feel the stress, right? Wrong! The &quot;false positive&quot; rate of a polygraph &quot;test&quot; is estimated to be about 50%. That is, assuming you&apos;re being truthful, there&apos;s still a 1-in-2 chance that the operator will conclude that you are lying. <br><br>For most honest people, simply being falsely accused of something is incredibly stressful, and polygraph tests are <b>not</b> designed to be reassuring in any way. Polygraph tests have been an integral part of innumerable false convictions and forced false confessions. If you are someone who cares more about justice than about securing a conviction (ie, you&apos;re a normal person, and not a police detective), I believe the more you look into this ridiculous tool of injustice, the stronger your moral conviction against it should be.
