Parapsychologists 'count' the improbable losses as evidence of paranormal abilities. It's called 'psi-missing'.
Sorry about the slow response.
I am totally with where you and Cuddels are coming from on the the probability missing being just as important as the probability of succeeding in any sort of trial. And it may well be an interesting follow up study to an MDC failure.
My point is, though, that the MDC is not a parapsychologist's study - it is a Paranormal Challenge. The only thing that is being tested (or should be tested, I should say) is the Applicant's claim. Now if, as in this case, the applicant's claimed success rate cannot be shown to be significantly better than random chance, I don't think that there's much more discussion needed by JREF on the MDC and the Applicant should try to ply his trade with a parapsychologist instead, perhaps.
The idea is that people deliberately miss through shyness or fear. Then you have the 'experimenter effect' whereby the belief or lack of belief of the person running the experiment influences the results.
I personally feel that these are just lame excuses by people that know that they cannot demonstrate any paranormal skills despite their brave boasting. I admit that this is a slightly peeving opinion based on observing such boasting for years on usenet and other forums including this one.
A skeptic will get ordinary results from their subjects, while a non-skeptic will get extraordinary results. Except, of course, when they don't. All of these effects are testable and applicable to the MDC. The problem is that none of them can be specified beforehand, but rather show up in the results a posteriori.
I disagree here, because this is not the nature of the MDC. While, yes, these *could* be tested by protocols designed for the MDC, the MDC is not a parapsychology study - it is merely a challenge for boasters to put up or shut up.
That is, if your results fall on the extremes of the normal curve (and remember, parapsychologists use an easier standard than is used in other scientific fields, as they usually use one-tailed testing), psi or psi-missing is present. If your results were ordinary and they can't be made to be extraordinary through sub-group analysis (a fairly easy task with enough heterogeneity), then they were performed in the presence of a skeptic. If after all that, they are still unremarkable, then a meta-analysis which includes poor quality studies (quality refers to the likelihood of producing the appearance of an effect when one is not present) so that a bias can be spread out over very large numbers and return p-values which dazzle you into not noticing effect sizes that represent not guessing one time in a hundred or a thousand or ten thousand, is supposed to persuade you that those people who used confirmation bias and informal observation to discover that they have amazing powers were really on to something.

But again, it is not the purpose of the MDC to be a parapsychologist study or metastudy, it is a Challenge only. While the
one of the aims of the JREF is to support and conduct research into the paranormal, it is not the aim of the MDC.
From the above link, "
About the Foundation";
To raise public awareness of these issues, the Foundation offers a
$1,000,000 prize to any person or persons who can demonstrate any psychic, supernatural or paranormal ability of any kind under mutually agreed upon scientific conditions.
It's pretty unequivocal as far as I can see. I don't believe that I'm entering into semantics or attempting to split hairs, I just don't see anywhere that the MDC purports to be anything but a Challenge. IF an applicant was sufficiently educated to propose in an Application the conditions, results and conclusions you outline above, I agree that the MDC *could* and should test such a claim, but the fact is that no one has opted for this approach as they inevitably boast only of great and significant successes, then backpedal when challenged with excuses about the skill not being consistent, often with the "excuses" you outlined above.
I put together a spreadsheet of all the claims to date (ok a year out of date) in an attempt to statistically analyse the types of applications and their relative success in getting tested. If I can find some time it may prove interesting to review those 8 or so tests to see if there are any failures that fall into the lower end of probability that we're talking about.
ETA: Cuddles, I hope the above addresses your last response to my post as well? I'm sure you'll point it out if it does not.
