Extraordinary claims are everywhere. You can learn your future, shed pounds without dieting and read about people who have been repeatedly probed by aliens. Skepticism, in the service of science, is a tool for evaluating an observation or a hypothesis. It is in the challenge of a hypothesis that a theory may rise or fall. Well, the truth is, sometimes you can't.
Some claims are simply outside of science.
Paranormal claims sometimes have scientific explanations that are, to my way of thinking, more satisfying than the more fantastic explanations favored by friends, family, television news shows or the tabloids. Sometimes it takes a magician to see what our untrained eyes simply miss. Magicians have caught psychics using tricks that scientists have missed. Still, it's pretty easy to spot suspect claims. The other day I was buying some soda at a liquor store.
