>Randi dedicated his time and energy to debunking shysters.

That's not how I see Randi. I see him as a profoundly dishonest person who claimed to be doing debunking when in fact he was not.

Debunking is great, but it requires actual attention and critique. Randi customarily dismissed weird claims and claimed that they had "failed his test." In fact he had not tested them; he had not done anything more than glance at them and toss the letters in his outbox or his trash.

For example, it is very weird to claim a human can go indefinitely without food. If presented as a miracle, this claim is called "inedia." Randi received letters from presumably delusional or dishonest people who claimed to be able to live without food in a miraculous sense. Randi claimed that he had debunked these claims but he never investigated them. If he had actually taken the trouble to debunk these claims, he would have been a real debunker. Because he dismissed the claims out of hand and declared victory, he was a charlatan. Randi was very willing to have CSICOP collect donations for his cause, but he did very little actual debunking.

If an honest debunker -- someone like Feynman -- had been approached by such a claim, Feynman would have met the claimant, said a lot of rude things, and written something informative. He might have actually taken some numerical measurements. That is the sort of debunking I would pay money for.

On very rare occasions, Randi tried to do some real debunking. The results were not what I would call satisfactory. His colleagues at CSICOP (later CSI) were a little more diligent, but not very good at debunking. An example is the Demkina case.

CSI/CSICOP was supposed to be providing a team of experts, but they bumbled around like the Keystone Cops. CSICOP, to me, seems to have the same problem as allegedly "Christian" churches -- the preachers talk a lot, claim to embrace lofty ideals, collect monetary donations, and nothing useful happens. I don't believe these self-proclaimed "Christians" are worthy of the name -- why would I believe that self-proclaimed "skeptics" are worthy of the name?
