Can you please explain why you feel this particular fact is relevant to the discussion? You have brought it up multiple times in this thread as well as in other threads.
1. The National Academy of Sciences concluded from studies that the polygraph is unreliable, but better than chance. Any level of significance, when viewed in synergy with all the evidence, makes the polygraph result more significant than the opinions being expressed by posters in this thread as to GZ's truthfulness, IMO.
2. The polygraph result is consistent with the forensic evidence and consistent with all of the testimony except Jeantel's. Consistency of different evidence is mutually reinforcing, aka synergistic. When one piece of information stands out as inconsistent with the totality of the evidence, that piece of information should be thrown out. Conversely, a piece of information that is consistent with the totality of the evidence may have synergistic weight.
3. GZ's willingness to submit to a polygraph suggests an absence of intent to deceive.
4. A polygraph once caught me lying. I lied solely for the purpose of testing it. Nothing was on the line, I wasn't noticeably nervous, but it still caught me.
5. The police used the polygraph in this case as an interrogation aid. If the police can use it, I can use it. This is not a trial. The trial is done. This is an extremely opinionated post-hoc discussion.
It is my understanding that lie detectors are, at best, woo, that they are meaningless and the fact that George "passed" one is completely irrelevant and unimportant.
Unreliable as stand-alone evidence. Not meaningless. The polygraph is widely used by law enforcement as an interrogation aid. Also widely used to screen applicants for sensitive positions when the screening agency doesn't care about false positives.
Surely there are enough real facts in evidence to discuss that we don't need to bring up such a pointless and irrelevant "test."
Is each of those facts in evidence 100% reliable? Can any one fact in evidence be used exclusively to determine GZ's truthfulness on the key issues with greater than 80% reliability?
