Ah, yes, the Gauquelin affair – now I remember – your favorite fallback argument!
You won’t be able to pick much of a fight with me here – I have parted company with Kurtz, partly because he didn’t support Randi when the Geller suit came up. Although I fully agree with Kurtz’ philosophy and ideals, I think others (like Shermer, Randi, Plait) make better leaders for skeptics; their tactics and foci are in a better direction.
So My Eyes Have Glazed Over whenever the Gauquelin affair is mentioned. This has been going back and forth for a long time and it’s too time consuming to keep up with the details. So I won’t agree or disagree with you here. I do know that you like to pick out small details, possibly misunderstood, possibly unimportant, never significant, and harp away at them ad nauseum. I don’t have the stomach for that again.
I do think that the Gauquelin premise (that persons born under certain signs share significant characteristics that cannot be explained otherwise) has not been sustained by subsequent studies, and the hoped-for verification of astrology is no closer now than 50 years ago. Dennis Rawlins’ claims are as much BS now as ever, and I don’t see how Rawlins or Gauquelin relate to this thread.
As far “the test was fair because all participants agreed it was”, with regards to the OP, or dowsing, I am referring specifically to the Million Dollar Challenge from JREF. AFAIK, for all tests given under that banner, the participants:[ul][li]First are given a chance to perform without blinding, and they perform adequately,[]Sign a statement that they can perform as promised when blinded and that the test meets their requirements and is fair,[]Fail spectacularly when the test is blinded in a scientific manner.[/ul]No one has been able to prove any claimed dowsing ability of any kind exists under proper controls.[/li]
That’s the bottom line. Dowsing simply doesn’t work. Cecil said it, and I believe it.
Why does it appear to work to some? Wishful thinking and ignorance.
