I have to agree with Clause on this one.
The "study" mentioned in the OP assumes that polygraphs can connote anything meaningful. Considering that courts don't allow them as evidence, I don't quite see if they would stand up to scientific rigorous standards in any way, shape, or form.
If anyone can demonstrate that they are valid through studies, that would go a short way towards giving any sort of credibility to their tests.
Though there's still that issue of a too-small study sample, and various other factors.
Excuse me, but is this not the "James Randi Educational Foundation"?
I would like to think that people would be able to learn things, such as, say, whether or not polygraphs work.
And how exactly is that off topic for a thread that states, from it's very premise, that a polygraph was used, even if the case is fictional? I don't see why explaining that polygraphs are not reliable is somehow OMG OFF TOPIC TERRITORY!
Perhaps you should explain your logic as to why the subject shouldn't even be discussed, whether or not the original story was fictional or not?
