The matter with data

Truth

Would you believe that chocolate actually reduces your chance of getting cavities? Or that milk is the number one health hazard facing young children?

Well, the first study was commissioned by the M&M/Mars Company and the second by an antidairy vegetarian group. And that, says an outraged newspaper reporter, is warping everyone's sense of truth. Buying and selling information to advance private agendas is only one way truth gets twisted, according to Cynthia Crossen of The Wall Street Journal. More and more of the information we use to buy, elect, advise, acquit, and heal has been created not to enlarge our body of knowledge but to sell a product or advance a cause.

In a new book, Tainted Truth: The Corruption of Fact in the Information Age (Simon & Schuster), Crossen charges that in the information business, truth has come to belong to those who commission it. Unfortunately, regardless of its source or validity, the majority of statistical information is swallowed by the public.

Even medical studies are not exempt. Like product surveys and public opinion polls, many are conducted under conditions skewed by biased researchers--and still remain well within acceptable standards. Even the simplest public opinion poll can be contrived to obtain a desired result by the wording of questions, their order, and whether a question is multiple choice or open-ended.

But there are ways to get to the truth. Crossen suggests: Demand to see the technical index--a list of methods, data, and study population--required of every credible survey. She urges Americans to become active, not passive, thinkers. Freedom of speech hardly ensures its truth, even in numbers.
