Lie detectors tell you nothing really.. yeah they can be accurate, but not always. Some people can fool them and others could just be nervous because they know they're being tested.. it's relying on a machine to determine a person's fate, not good.

ANSWER #5 of 7

There is no such thing as a lie detector. There is a polygraph test that measures several physiological responses. We tend to have physical reactions to lying but detecting deceit from these responses is tricky and entirely subjective. I've met several people who's careers have been ruined because they volunteered to take a polygraph test to clear their name only to find out that they "failed" it. You have nothing to gain and everything to loose from taking a polygraph test; especially if you are innocent. Nobody should volunteer to take a polygraph test and it is foolish to work for companies that require them as a condition of employment. Employers and law enforcement may claim that declining to take a polygraph test itself is considered an admission of guilt but don't fall for it.
