Legions Put Their Faith in Superstition and Pseudo-Science
Why do so many people put their faith in pseudo-scientific pursuits such as astrology, alternative medicine and psychics? ABCNEWS' John Stossel seeks to find out in his special report, "The Power of Belief". Stossel walks on hot coals, visits New Age emporia, checks the accuracy of his horoscope, and invites a voodoo priest to place a curse on him.

He discovers people are attracted to belief - often in defiance of evidence. It begins at a young age, with our capacity for imaginative play. Stossel talks to a group of children as they create - and come to believe in - an imaginary fox. "There is a fox, there is a fox, I know it. We saw one, I know it!," says a child.
