Did you ever have the uneasy feeling the experts are not . . . well, expert? "Stocks have reached what looks like a permanently high plateau." --Irving Fisher, professor of economics at Yale University, October 17, 1929 "Forget it, Louis, no Civil War picture ever made a nickel." --Irving Thalberg's warning to Louis B. Mayer regarding Gone With the Wind "We don't like their sound. Groups of guitars are on the way out." --Decca Recording Company executive, turning down the Beatles, 1962 "With over fifty foreign cars already on sale here the Japanese auto industry isn't likely to carve out a big share of the market for itself."--Business Week, 1968 "There is no reason for any individual to have a computer in their home." --President of Digital Equipment Corporation, 1977 "Bill Clinton will lose to any Republican who doesn't drool on stage." --The Wall Street Journal, in a 1995 editorial The Experts Speak systematically catalogues, footnotes, and sets straight these and a couple of thousand other examples of expert misunderstanding, miscalculation, egregious prognostication, boo-boos, and just plain lies. The experts have been wrong about everything under, including, and beyond the sun: time, space, the sexes, the races, the environment, economics, politics, crime, education, the media, history, and science. In this expanded and updated edition (now more error-filled than ever), we see just how much the experts don't know.  But the book also goes deeper, presenting a through-the-looking-glass chronicle of human knowledge: the story of what was and is so, as seen through the story of what we wanted to and did believe.
