A person who studies mental control of biological functions or eastern meditation can play a polygraph however they like.
Right. I discussed this on another thread. Some people are mentally ill and do not worry about lying at all, so will remain calm (sociopaths, people with strong delusions who can calmly and honestly say the spaceship aliens told her about Kavanaugh and what they said was true.)
And what if the phony agent gave her five tests until one worked okay? What professional conditions were adhered to?
