A polygraphy doesn't actually say "truth" or "lie".. it records vital signs, and the assessor makes a determination based on the results of the vital sign readings vs. typical human bodily reactions to telling lies. It's not a guaranteed method by any means, and that's why polygraphy results aren't eligible to be submitted as evidence in court.

Yes and no. What polygraph machines do is monitor specific biological functions such as pulse and skin temperature. The polygraph operator asks a series of test questions with known answers to esatblish a baseline for the subject. When humans lie there are a few typical responses, such as an elevated pulse. The polygraph operator decides whether or not the subject has responded honestly or not based on the changes in the measured functions.

Yes. Polygraphs are designed to detect heightened levels of anxiety, they cannot detect whether someone is telling the truth or lying. Most people when they lie become anxious/nervous, however if someone suffers from anxiety or is particularly nervous the polygraph will also detect this. If the examiner refers to the polygraph as a "lie detector" then the chances are they have little understanding as to the function of the machine and would likely mistake someone with anxiety as a chronic liar.
