Freedman (coauthor of A Perfect Mess
) makes the case that scientists, finance wizards, relationship gurus, health researchers, and other supposed authorities are as likely to be wrong as right. Drawing from personal interviews with experts on experts, he leads the reader on a merry chase down the road of skepticism, uncovering conflicting solutions to how to sleep better, lose weight, avoid heart attacks, build a financial nest egg, lower cholesterol, etc. In accessible language, Freedman explains the flaws that all too easily worm their way into research, including deliberate fudging of data and downright fraud. Fellow journalists, more interested in flashy copy than accuracy, come in for their share of the blame. Google and other Internet search engines add to the problem, sending unfounded “facts” to millions of computer users. Fortunately, after pulling the rug from under the reader's feet on every imaginable topic—from the relationship of body fat to dementia, the effect of Tylenol on dogs, and how to prevent inflation, Freedman provides 11 “never-fail” rules for not being misled—but of course, he admits, he could be wrong.
