The polygraph industry continues to claim an accuracy rate of over 90%, but they never cite the "studies" that back this up - simply because there are no such studies. The only investigative study that has ever been done on the accuracy of the polygraph as a lie detector was done by CBS 60 MINUTES - and that study proved the polygraph was 100% wrong 100% of the time. Three separate polygraph operators called three different innocent truthful people liars on a crime that never even happened. Check it out: https://youtu.be/ziMAoHhxiYQ
From the aforementioned article...
But Hopkins allegedly also told police she must have "blacked out" and was "so drunk that she did not remember," saying she had drunk whiskey and ingested the antihistamine drug Benadryl, according to a police affidavit filed with the court.
In my professional opinion, even the most rabid polygraph apologists will have a tough time defending this particular "test."
The defendant's admitted lack of self-awareness during the time in question is a gross violation of Backster's "Distinctness of Issue" requirement.
