An Epidemic of False Claims
False positives and exaggerated results in peer-reviewed scientific studies have reached epidemic proportions in recent years. The problem is rampant in economics, the social sciences and even the natural sciences, but it is particularly egregious in biomedicine. Many studies that claim some drug or treatment is beneficial have turned out not to be true. We need only look to conflicting findings about beta-carotene, vitamin E, hormone treatments, Vioxx and Avandia. Even when effects are genuine, their true magnitude is often smaller than originally claimed.

The problem begins with the public’s rising expectations of science. Being human, scientists are tempted to show that they know more than they do. The number of investigators—and the number of experiments, observations and analyses they produce—has also increased exponentially in many fields, but adequate safeguards against bias are lacking. Research is fragmented, competition is fierce and emphasis is often given to single studies instead of the big picture....

I Fooled Millions Into Thinking Chocolate Helps Weight Loss. Here's How.
...We science journalists like to think of ourselves as more clever than the average hack. After all, we have to understand arcane scientific research well enough to explain it. And for reporters who don’t have science chops, as soon as they tapped outside sources for their stories—really anyone with a science degree, let alone an actual nutrition scientist—they would discover that the study was laughably flimsy. Not to mention that a Google search yielded no trace of Johannes Bohannon or his alleged institute. Reporters on the health science beat were going to smell this a mile away. But I didn’t want to sound pessimistic. “Let’s see how far we can take this,” I said....

...With the paper out, it was time to make some noise. I called a friend of a friend who works in scientific PR. She walked me through some of the dirty tricks for grabbing headlines. It was eerie to hear the other side of something I experience every day.

The key is to exploit journalists’ incredible laziness. If you lay out the information just right, you can shape the story that emerges in the media almost like you were writing those stories yourself. In fact, that’s literally what you’re doing, since many reporters just copied and pasted our text....
