What he said.
It's "negative proof" again.
Now, if you're talking "open mind" in the sense of "this is kind of cool, and I wonder if they're going to find some real proof someday, but this item certainly isn't it," that's okay by me. That's how I think about these things.
The hard core anomalists say "there it is, it's settled."
"Negative proof" takes the proposition that if you can't proof it's false, therefore it's true. The second part is where the problem comes up. I'm not sure Jeff is taking it that far.
