Sorry Nick, I have to disagree. Of course a scientific experiment can never prove that the phenomena are not real, merely that they don't occur reliably under the conditions of the experiment. It can never prove that a phenomenon is real and is as stated either - it can merely provide evidence for a certain line of thought. This is why scientists refer to theories.
[edit: I should have put "attempt to clarify" rather than disagree. I think I misread something you wrote]
(Remember the words of Einstein "No amount of experimentation can ever prove me right; a single experiment can prove me wrong.")
What I think you were trying to say is that it's impossible to prove by experiment that something can't be done.
Despite having been accused of it before. I'm not fan of Randi, although I have some sympathies with some of his ideas. I imagine in certain circumstances the prize money would be able to be claimed, although they would almost certainly be set in such a way as to make it impossible to claim for most people.
Of course Randi can't offer a prize in a field as wide as this, and publish the rules for all cases in advance, otherwise he'd be in significant danger of leaving out a specific case, and having to hand over the money to some harmless old codger with a well known card trick, just because the rules weren't specific enough for testing for that case.
To accuse Randi of being unscientific is probably accurate, but possibly unfair, as the very things that are being questioned are not by nature things that submit well to rigourously scientific testing.
True scientific method can't really be applied to people, their reactions, emotions, and agendas - the basis of it is that there is a level playing field for testing in the first place. Further, it's almost impossible to be correctly scientific about repeatable studies, as I imagine it's often claimed that the applicant has special powers that can't be repeated by just anyone. Repeatability is key to being accepted by the scientific community.
When a scientist measures a specific property of a sample, a substance will be tested a number of times, and the results recorded and analysed, but there is no question of the sample having an agenda to fool the scientist, so it is not examined on that basis. The general trend of evidence with be used to build a hypothesis, which will then be examined and tested by other scientists to see whether there is a consensus, and modified if necessary.
Randi's challenge may be dressed in scientific terminology, but by the very nature of what he's trying to test/debunk, it can't be truly scientific. Randi has an agenda, in just the same way that Joe Spoonbender has an agenda.
Randi states that he doesn't believe in paranormal phenomena (or whatever), and Joe Spoonbender states that he has incredible an unusual powers. This is by nature a confrontational dispute, and can't be solved directly by scientific approach, although scientific methods may be useful to both parties in demonstrating their case.
It seems completely appropriate to me that the testing should be setup in this way, although I think it's probably appropriate that people have an understanding of what the aims of the challenge are, and the agendas involved. Anyone who thinks that the foundation has no agenda clearly hasn't understood the situation.
It may be appropriate for someone else to be appointed to judge the criteria, but under those circumstances, it would possibly also be appropriate for any applicant to put up equal money to that they are trying to claim (in the manner of a bet). As it is, the claimant is wagering nothing (other than the dubious value of their reputation) against the possibility of winning a large sum of money. Randi may have an agenda, but he's probably not insane - anyone would be a bit cautious about criteria and judging under those circumstances.
