The tests are completely arbitrary, based on the individual Psych doctor who interprets the results. Just like the phony polygraph aka "lie detector" tests. Poly tests are about as reliable as a hamster reading your palm and telling you what your future will hold.
All a polygraph does is record a physical reaction to what should be a "yes/no" question and compare that reaction against a control question and its reaction.
You don't really beat the machine, it doesn't say anything other than what your body did when you answered a question.
At least when I had mine - that's how the examiner explained it to me. You never beat the machine, it's a measurement device. You beat bad questions/examiners.
I do wonder how society would be were we to simply do away with all law enforcement and let the citizens handle things themselves...
