It’s refreshing to see a new book on pseudoscience, given how rampant belief in all sorts of nonsense is these days, especially (but not only) in the United States. Kang and Pedersen cover an impressive range of unscientific claims, from the obvious ones (UFOs, Bermuda Triangle, ghosts, cryptozoology, and so forth) to the more esoteric ones (I bet you never heard of “Lawsonomy”!). The various chapters are organized under four major headings: “Pure nonscience” (flat Earth, perpetual motion machines, phrenology, and others), “Aliens! Ghosts! Bigfoot! Atlantis!” (the title of the section being self-explanatory), “Wishful Thinking” (cryonics, astrology, personality psychology, ecc.), and “Grifters, Nihilism, and Denialism” (fake Moon landings, climate change denial, dowsing, and so on). The book is indeed an amusing history of crackpot ideas, though much less discussion, unfortunately, is devoted to the second part of the subtitle: why people love this sort of crap so much. That would have required a deep dive into research in both personal and social psychology, and perhaps it can be left for another book. In each chapter, Kang and Pedersen present their subject matter in a captivating and entertaining fashion and then proceed to the debunking, though the latter could have been a bit more in-depth in some cases. All things considered, this is a must-read for anyone seriously interested in pseudoscience. Mind you, it will not change any true believer’s opinion, but that’s not its goal anyway. “Pseudoscience” is for the rest of us, who have no trouble agreeing to the proposition that there is no Big Foot and yet are befuddled by the fact that so many think otherwise.
