8. Polygraphs are anxiety detectors, not lie detectors

The only thing polygraphs show is the degree of anxiety over the questions the polygraph administrator asks. They're useless for their traditional purpose, i.e., detecting liars.

Sociopaths can easily ace polygraphs and persons with anxiety disorders will no doubt flunk them, even when they're telling the truth.
