Bad Science is an excellent entry to the genre of skeptical books that are, in this country, associated with Michael Shermer, James Randi, and Paul Kurtz. It is a pleasure to read, both because Goldacre writes well, and because the books from Shermer, et al, are very similar to each other and this one is in many regards refreshingly different.
Part of this stems from its national origin -- this is a very British book. As a result, it has a lot more about the MMR-vaccine-causes-autism nonsense than would have appeared in an American book, as the media panic in the U.K. was much greater than the one here. It similarly has less on faith healing and other topics that loom larger in the American consciousness.
But the book also differs in approach. In the quintessential American members of the genre, various bits of nonsense are debunked with a combination of common sense and powerful anecdote. American writers are particularly fond of grand gestures, sneaking into the back room and discovering the wizard hiding behind the curtain. That's not Goldacre's style at all. Instead, his favorite tool is the statistical blobbogram. The main targets of his scorn are holistic healers, vendors of pharmaceuticals and vitamins, who lie and abuse statistical techniques to mislead people into buying products that don't work instead of using ones that do. He similarly rails against the journalists who enable these malefactors.
Goldacre is a physician, so he spends most of his time on medical topics, but not all.
I enjoyed and appreciated every chapter of this book, and I hope many other people read it too.
