I agree with HiddenTruth and prase. The original post is flawed, because it starts with a perfectly good idea: "if there were a group that 'did science' but was always wrong, it would be a good control group to compare to 'real science'", but then blows it by assuming parapsychologists are indeed always wrong.

FWIW, I too believe parapsychologists are probably almost always wrong, but so what? Who cares what I believe? No one does, and no one should (without evidence), and that's the point.
