Have you ever wondered how one day the media can assert that alcohol is bad for us and the next unashamedly run a story touting the benefits of daily alcohol consumption? Or how a drug that is pulled off the market for causing heart attacks ever got approved in the first place? How can average readers, who aren't medical doctors or Ph.D.s in biochemistry, tell what they should be paying attention to and what's, well, just more bullshit?
Ben Goldacre has made a point of exposing quack doctors and nutritionists, bogus credentialing programs, and biased scientific studies.

And he wants you, the reader, to share his feelings . . . There's more here than just debunking nonsense. The appearance of scienceiness': the diagrams and graphs, the experiments (where exactly was that study published?) that prove their efficacy are all superficially plausible, with enough of a hassle barrier to deter a closer look. Dr. Goldacre (a very boyish-looking 36-year-old British physician and author of the popular weeklyBad Sciencecolumn inThe Guardian) shows us why that closer look is necessary and how to do it . . . You'll get a good grounding in the importance of evidence-based medicine . . . You'll learn how to weigh the results of competing trials using a funnel plot, the value of meta-analysis and the Cochrane Collaboration. He points out common methodological flaws . . .
