The problem with lottery tickets is that in buying one, you accept that the chances of winning are slim to none. The expected payoff of any activity which tests if knowledge is true, is true knowledge. I always win that gamble, so long as I play the game (as stated previously in numbers 1 through 4). And it is about fun--what's more fun than educating people, helping people, finding new stuff, or validating someone's claims? Seems like the essence of science to me... Skepticism is useful only when you know something the one making the claim doesn't know, after all. For example, the probability of Deepok Chopra's ideas about the mind being correct are so small because of what we already know about psychology, and because his stuff contradicts itself. Deepok Chopra's claims are, therefore, not worth testing, not because all weird claims are not worth testing, but because even the payoff of "proven wrong" may be impossible in such a case (no learning will take place).

PS: I suspect I'm getting something wrong here. Still, I will go forward, to see what I can learn. As I said, I look forward to seeing how people estimate the whole cold fusion business. So, what kind of game do you think is being played? Is this the same as playing the lottery (dumping money into something that won't even produce learning, and hence fun)? Is it worth it to test cold fusion, based on previous knowledge? Why? My own position is, of course, cautious optimism (not investing in cold fusion for a while yet), because I expect to see SOME kind of reward no matter the outcome--it SEEMS to me like scientists are doing science, here (not that I know enough to say with 90 percent certainty)...
