John Grant's "Bogus Science" is the latest in his series of highly readable and entertaining books, the first two being Corrupted Science: Fraud, Ideology and Politics in Science and Discarded Science: Ideas That Seemed Good at the Time.... Grant begins "Bogus Science" with the customary lament about the state of scientific knowledge in modern society. Among other things, according to recent polls, 20% of Americans believe the sun orbits the earth, 25% reject Darwin's law of evolution by natural selection, 36% think the matter is still open to question, and only 39% understand that evolution by natural selectiuon is a correct description of reality. A 2009 survey of Britons found, among other things, that 39% believe in ghost, 22% in astrology and 27% in reincarnation. And these numbers have purportedly risen significantly since the 1950s, suggesting that people believe more unscientific things than ever. (Perhaps, but it's also possible that people are more willing to share their odd beliefs with a stranger than they were in the 1950s, or even that some folks enjoy giving silly answers to pollsters' silly questions.)
Regardless, the apparently dismal state of scientific knowledge and the presumed need to fix it are good excuses for a romp through the history of odd beliefs. Grant discusses the origins and status of a wide range of theories about flat and hollow earths, legendary vanished civilizations (Atlantis, Mu and Lemuria), perpetual motion machines, anti-gravity devices, ancient astronauts, seamonsters and Sasquatches, all in a readable style and with wit and erudition. The author is generally kind to his subjects and their beliefs, although he from time to time makes his views clear with a bit of sarcasm. On the whole, I think "Bogus Science" goes well with other "gently skeptical" books like Brian Dunning's Skeptoid: Critical Analysis Of Pop Phenomena and Skeptoid 2: More Critical Analysis Of Pop Phenomena and Gregory Reece's Weird Science and Bizarre Beliefs: Mysterious Creatures, Lost Worlds and Amazing Inventions.
