How do we know if a treatment works, or if something causes cancer? Can the claims of homeopaths ever be as true – or as interesting as the improbable research into the placebo effect? Who created the MMR hoax? Do journalists understand science? Why do we seek scientific explanations for social, personal and political problems? Are alternative therapists and the pharmaceutical companies really so different, or do they just use the same old tricks to sell different types of pill? We are obsessed with our health. And yet – from the media’s ‘world-expert microbiologist’ with a mail-order PhD in his garden shed laboratory, via multiple health scares and miracle cures, to the million pound trial that Durham Council now denies ever existed – we are constantly bombarded with inaccurate, contradictory and sometimes even misleading information. Until now. Ben Goldacre masterfully dismantles the dodgy science behind some of the great drug trials, court cases and missed opportunities of our time, but he also goes further: out of the bulls---, he shows us the fascinating story of how we know what we know, and gives us the tools to uncover bad science for ourselves.
