She only fails if she’s wrong. Non-paranormal methods she may use to detect a missing kidneys would only help her to be right not wrong.
Thank you, Captain Obvious.
Stopping a test that requires 100% success after a failure isn’t an advantage, it’s common sense.
Another assertion with no reasoning behind it.
The problem that she may be able to identify a missing kidneys by non-paranormal means is common to all tests.
Yes. Exactly.
You seem to be saying that because there is a possibility she can cheat then a “correct” answer can never be accepted as an actual correct answer.
Where in the world did you get that idea? I never said any such thing. Seriously, man, is English your native language?
In other words she can never claim to win. So what’s the point of running any test unless your only intention is to prove her wrong?
1) She can claim whatever she wants.
2) The results are self-evident, so #1 doesn't matter.
3) If a claimant wins the challenge, it has proven nothing to the world of science. The most likely reason for success is cheating, probably by collusion. Otherwise, why accept the challenge in the first place?
4) Failure indicates that the ability described did not function as claimed.
Let me try to explain the problem with stopping again because you're just not getting it. By itself and in a vacuum, stopping confers no advantage to the claimant. However, it doesn't happen in a vacuum. Stopping at the first wrong answer by definition requires affirming all of the correct answers up to that point. This is providing feedback to the claimant, who, as you admit above, may be using some ordinary means of making educated guesses rather than relying on the fantasy they call a paranormal claim. Feedback provides an advantage to the claimant.
That aside, there's another very important reason not to stop testing. Suppose on the very first trial the claimant gets it wrong. You stop the test. Later, upon reviewing the tape, the claimant finds that you violated protocol. This automatically means a retest.
Suppose you proceed with all 12 trials (or however many) and the claimant misses the first one and the last one. The same violation is found in the first trial but not the last. Since the claimant still had one miss, there are no grounds for a retest because the single mistake did not affect the outcome.
If you can't understand the feedback issue, surely you can understand this very simply concept.
