That’s correct. A polygraph works by measuring subtle physiological changes that typically occur during stress. Most normal people feel stress when lying.
Sociopaths don’t. Pathological liars don’t. They sail right through polygraphs.
Note that polygraph results are not admissible in court due to their unreliability.
exactly.
many accomlished or routine liars (the ones you really want to catch!) sail right thru lie detector tests
and
some honest people get so nervous being electroded and questioned .. that they flunk LD Tests even tho they are truthful
these reasons are why LD tests are inadmissible in court and why a normal person should NEVER submit to LD testing, imho.
too much risk of error that could cause serious problems
“That’s correct. A polygraph works by measuring subtle physiological changes that typically occur during stress. Most normal people feel stress when lying. Sociopaths don’t. Pathological liars don’t. They sail right through polygraphs.”
And some people get stressed by being put on a polygraph, even though they are telling the truth.
If the Federal Gov’t rank and file must take polygraphs on demand then so should the top brass. polygraphs are very reliable these days. They are not admissible but tell that to the lower level workers than are fired upon poor test results. Make the big shots take them also. Whats the difference if they don’t work well in a small percentage of cases. There are other ways to catch the bad guys.
