Here's a secret. They don't really care about any readings. It's just a tool for interrogation and gaslighting you. If you're doing stuff like squeezing your sphincter, yea they have sensors on the chairs to detect that.
Polygraphers are skilled at reading people & telling stories. But them reading the machines? It's kinda nonsense - they'd only read results to find excuses to gaslight you. They pretend to rip off the polygraph sheets and yell. Playing good cop/bad cop and making up stories to try to build a rapport. It's really just an interrogation. If you can handle being yelled at for a week, then you'd pass.
