What kind of skeptics are you? Imagine this, similar to the scenario earlier, Ug comes along, and does the exact card trick Randi outlined in his commentary, and says "I can do that coz I'm psychic" I cry out in anguish and all my friends go "He must be psychic" and I say to Ug "Prove you are really psychic do it under controlled conditions so everyone can see." But Ug won't prove it, he says "Just believe I'm psychic".
Then oh fellow skeptics, Randi comes to town, does the exact same trick, and says "I am NOT psychic, it was a trick" All my friends go "He's right, Ug was a fake" and I say to Randi "Prove it was a trick, show us all how the trick was done, so that we might be wiser and avoid being fooled again" but Randi won't prove it, he says "Just believe I'm not psychic"
Well where the hell does that leave me? I must choose to take someones word for it. That aint good enough I'm afraid. And why is it that I have to go out and spend money to find out how the trick was done? Why won't people just tell me?
