Magicians are the most honest people in the world; they tell you they're gonna fool you, and then they do it. - James Randi

There exists in society a very special class of persons that I have always referred to as the Believers. These are folks who have chosen to accept a certain religion, philosophy, theory, idea or notion and cling to that belief regardless of any evidence that might, for anyone else, bring it into doubt. They are the ones who encourage and support the fanatics and the frauds of any given age. No amount of evidence, no matter how strong, will bring them any enlightenment. They are the sheep who beg to be fleeced and butchered, and who will battle fiercely to preserve their right to be victimized… the U.S. Patent Office handles an endless succession of inventors who still produce perpetual-motion machines that don't work, but no number of idle flywheels will convince these zealots of their folly; dozens of these patent applications flow in every year. In ashrams all over the world, hopping devotees of the Maharishi Mahesh Yogi will never abandon their goal of blissful levitation of their bodies by mind power, despite bruises and sprains aplenty suffered as they bounce about on gym mats like demented (though smiling) frogs, trying to get airborne. Absolutely nothing will discourage them.

The conjuror or con man is a very good provider of information. He supplies lots of data, by inference or direct statement, but it's false data. Scientists aren't used to that scenario. An electron or a galaxy is not capricious, nor deceptive; but a human can be either or both.

Uri Geller may have psychic powers by means of which he can bend spoons; if so, he appears to be doing it the hard way.
