My brother-in-law's father is a schizophrenic who believes the Government monitors his thoughts. He would pass a lie detector test because he truly believes this. I think it was the guy who killed Rebecca Sheafer who passed a lie detector test that he was in a relationship with her.
This woman could have been bought a drink in a bar, developed a fantasy and now believes it to be true. We don't know. But the lie detector test is not fail safe.
The device is wrongly referred to as a lie detector. It is actually a polygraph. It measures breathing rate, pulse, blood pressure, and perspiration. If you are calm and you do not get flustered or nervous during the polygraph you can pass the test. Shizophrenics,psychopaths, and sociopaths can pass the polygraph much easier than the average. joe.
