This is an interesting interview with Ray Hyman, who talks about how easy it is to fool people, for people to fool themselves, and why pseudoscience is so persistent. It's also nice to read Physicist Richard Feynman's excellent and justly famous piece on Cargo Cults. People do not look for disconfirming evidence. We are not cognitively well equipped to understand the world around us (the fact that we can at all is remarkable). Just for those of you out there who want to understand why the Web is suddenly filled with crazy people.
