The sqiggly lines on the page, have zero information about if someone is lying.
All a polygraph test is a Dick behind his proverbial bones/tea leaves that gives a reading based on nothing more than if he/she likes you.
The other method is to simply be born a psychopath with an absence of conscience
No you fucking don't. Polygraphs don't work. THEY ARE BULLSHIT. Reading fucking tea leaves is as effective at detecting a lie as a polygraph. The guy who "invented" the polygraph when on to show that if you hook up the polygraph to a *plant* it can *read your mind*. This shit is crazy. Even worse is the credibility of any organization at all that puts any stock into a polygraph test.
Long story short. You can just lie to defeat (what does that even mean here) a polygraph.
