I've heard about this before and have thought about the problem, but even if I hadn't, hearing the same superstition repeated many times does not make it real.

I've heard about this before and have thought about the problem, but even if I hadn't, hearing the same superstition repeated many times does not make it real. I'm willing to bet a small sum of money, say, $100 for 75%, but as I said, I tried to come up with a good experiment and I find it quite hard. I think that a more productive continuation to the discussion would be a collaborative attempt at inventing such an experiment, rather than just throwing spewing inflammatory rhetoric.
