No. What you're missing is that the judging process necessarily has two steps: (1) Judging which of the six subjects is missing a kidney; and (2) Judging for the subject that was selected the location of the missing kidney. If (1) is incorrect, (2) is necessarily incorrect, but it's illogical to discount (1) being correct on the basis that (2) was incorrect. If you think I'm wrong, please set forth your probability calculation.
No probability calculations necessary. You're wrong about the judging process. It was based on 100% success in Anita's claimed ability to see the location of a missing kidney. Seeing a kidney where there wasn't one and not seeing a kidney where there was one are both wrong guesses, 100% wrong, regardless of which person the wrong guesses applied to. If you think some points should be given for close-but-no-cigar, guessing the wrong side on a person missing a kidney is actually two wrong guesses and is therefore
further from being correct, not closer. The only thing significant about any of her wrong guesses is that they were, well, wrong.
Let's say this is the line-up. Six people sitting in a row. The
X is the missing kidney...
OO --- OO --- XO --- OO --- OO --- OO
This is the wrong guess...
OO --- OO --- OX --- OO --- OO --- OO
According to the protocol
and the claim made by the woo peddler, it is exactly as wrong as this...
OO --- OX --- OO --- OO --- OO --- OO
A wrong guess of the next one over,
to the left or to the right of the correct position, is exactly as wrong as this...
OO --- OO --- OO --- OO --- OO --- XO
... your insistence on redefining the claim and the requirements for success as spelled out in the protocol notwithstanding.
