Just because a person passes a polygraph test doesn't mean a thing because people can be trained to pass polygraphs. I can imagine a Buddhist Monk in perfect tranquility being the perfect candidate. In order to pass a polygraph test you must control your heart rate and breathing rate, there are people that can lie with out missing a beat.

While it’s possible to fake a test, it’s not as simple as most would like to believe. The main ways are drugs (apparently ruled out), an abnormally high baseline (which can be spotted by a decent examiner) and by being a psychopath (how a guy like Ted Bundy was able to pass).

There is a reason that polygraph tests are commonly used by law enforcement even though they are generally not admissible in court.

You don’t have to be a zen master. Every test has control questions — something like “have you ever taken office supplies home?” that provoke a guilty response. Learn to spot the control questions, put a tack in your shoe, and you can generate a stress response to the control questions. That way, you can mask the lies.
