The gap in the plot
She had previously stated that the demonstration would not falsify her claim, at the most she would simply stop calling it paranormal.
Anita's magical x-ray vision performed exactly the same as the non-magical body language cues an audience member used to make his guesses. Will she admit she used that same technique?
ETA: Also, many of the issues I have with the protocol weren't reflected in how the test was actually conducted. For example, the protocol did not specify that all the subjects would have the same color and style t-shirt and wear the same straw hats and head cloths. It also didn't specify that they'd all be sitting backwards in chairs resting their arms on the cushioned chairbacks (which doubtless reduced a lot of the fidgeting). It also didn't specify how the groups of subjects were selected or assigned.
I found the whole thing horribly sad. The spectacle this girl is making of herself in order to maintain an illusion that does not benefit her in any real way. One can only hope that she'll realize she didn't lose, she was thrown a life-line. She can now escape the trap she's built around herself and move forward into a happier adulthood that is less reliant on silly props and pronouncements. I wish her all the best.
Was it poor protocol design that allowed a 23% chance of a hit that too the layman *looks* much more unlikely? In fact, can someone talk me through how that % is arrived at?
But is that right? It wasn't 36 independent trials - we knew that only 1 kidney in 12 was missing (0.08333). 3 would be the correct value for n, yielding a 23% chance of getting 1 or more correct.OK. Go to http://www.graphpad.com/quickcalcs/binomial1.cfm and enter the n, that is 36, the number of potential kidneys. The number correct is 1, the probability is .083333333333333333, and hit "calculate".
Playing with that calculator with various p values and n can be quite enlightening. For example, if you flip a coin ten times, what's the odds of getting seven or more heads?
Less than what she got.
I would like to try and help Anita, if she continues her involvement in FACT. This whole thing got started when I invited Anita to our monthly meeting after reading her posts lo those many years ago (what do you mean it's only been 12 months!?!?). A while back skeen posted a link to this I was wondering if anyone would like to discuss, in a reasonable non-combative manner, the possibility that Anita might really believe, on some level, what she says?I found the whole thing horribly sad.

It wasn't 36 independent trials, you are correct. But let's look at the whole picture. She looked at the backs of 18 people who had a total of 33 kidneys, a priori. Her task in each case was to determine who had a kidney missing and which one it was. We can consider that a total of 36 judgements, each of which had a p=.0833 chance of being correct. The number of hits was 1.But is that right?

I guess only ten people were allowed to download it. I must have been number 11. Has the www.stopvisionfromfeeling.com chat been archived anywhere?
