You can beat polygraph tests by tightening your sphincter during questioning. Tightening the sphincter increase the bloodflow, and that's one of the things a polygraph is measuring during an interview. So unless someone sticks a finger up your butt to feel if you're clenching or not, they will have no idea you're fooling the machine.

@dragonlordpeter9006 I'm just stating the facts. As long as polygraphs use bloodflow readings, you can fool the machine through strategic sphincter tightening. I know it sounds ridiculous but it's true. Doing this will cause a temporary spike in bloodflow which any medical apparatus designed to detect it will pick up on. Even Penn and Teller did an episode of "Bullshit" revealing this.
