This is a murky field. A polygraph does present useful information; it's just not necessarily whether the person is telling the truth. The major decision part of any polygraph system is the operator, and they need to have sp,e training in physical psychology to be predictably any good at using the equipment.
That's nice bullshit sandwich wrapped in pseudo-science bread you've got there.
Polygraphs only work in the way that swinging a five dollar wrench at someone works. It convinces them to tell you what you want to know on their own because their afraid of it. That's it.
The phrase "He failed/passed a polygraph" is the biggest load of shit in "law enforcement."
