Check out FLIM FLAM, by James Randi, introduction by Isaac Asimov, quote Asimov ""Folly and Fakery has never before been as dangerous as it is now".

It seems to me that in this age of information, people are not well prepared to sort through misinformation and fraud, to reason and be able to use critical thinking.

Other books by James Randi are "An Encyclopedia of Claims, Frauds, and Hoaxes of the Occult and Supernatural", introduction by Arthur C. Clarke, "The Faith Healers", by James Randi and Carl Sagan, "The Mask of Nostradamus" by Randi. "The Demon Haunted World" by Carl Sagan is another good one on this subject.
