Why do people, even smart and educated people, believe absurd things? Why don’t they get that exceptional claims require exceptional evidence? If you believe that this is a fascinating and sometimes amusing, but more often tragic part of the human condition then the series of books by Martin Gardner are essential. His “Fads and Fallacies in the Name of Science” was a revolutionary compendium of what can easily be dismissed as stupidity and delusion. That is, if so many people didn’t believe in them. But these magical ideas are so seductive (dismissing the most absurd – flat earth, hollow earth, etc.) – can water have memory? Does the body have an inner energy? - that without someone to point out that “the emperor has no clothes,” and to do so wit and brilliance, the dividing line remains squishy. Well the dividing line does remain squishy. As Gardner pointed out from the beginning, and repeats in SGBaB, there is a spectrum of nonsense from the flat earthers on one side, through chiropractic and homeopathy, to the seeming nonsense of time reversal that is actually quite true (modern physics). But to most people a guide like Gardner is essential in the clarification of this spectrum – once identified it becomes quite easy to place (most) pseudoscience with great confidence.
So why read another book on the same subject, this one mostly constrained to PK and ESP? Because it’s fun! OK, most of it – since this is many years of essays and reviews there is much repetition as the same intros need to be given and the same targets taken down (I get it, Uri Geller is a good magician posing as a PK and fooling a lot of physicists with huge egos and poor sense of grifting). The best essays are reviews on popular science books – astrophysics, brains, catastrophe theory, etc. But all with the Gardner sparkle.
