Beyond that, polygraphs are garbage and unscientific. When I was in high school, one of my teachers

invited a psych prof in every year with basically the equivalent of a polygraph, which tracked heart rate, body temp, et cetera. I volunteered to be hooked up in front of the class because I was curious about its legitimacy. In less than two minutes of being hooked up to it, I began to figure out how to lower my heart rate and body temp. He had some auditory gizmo hooked up as well, and if your heart rate and body temp rose, it would squeal higher and higher. For the kid before me, it was squealing the whole time. After a short period, I had it sounding like bass. The teacher said, "Frankly, no one has ever taken it as low as MAS." I am 100% confident in saying that bright people can figure out how to "fool" polygraph machines, and I know it has happened before in high-profile criminal cases. I may be wrong, but I believe Kenneth Bianchi, one of the Hillside Stranglers, did this at some point when detained by police.
