Last week I wrote about a study that purported to show that antidepressants have no effect in mild to moderate depression. A careful reading of the paper shows that the authors dramatically overstated their findings, particularly in their public statements to the media. The study has another implication beyond the misleading claims about antidepressants. It is an object lesson in an ongoing and disturbing phenomenon in mainstream journalism, the wholesale reprinting of press releases of scientific papers instead of reading and analyzing the papers themselves.
Pick up any newspaper or magazine and you can read about the latest scientific breakthroughs in cancer, Alzheimer’s or heart disease. Just keep in mind that what you are reading is probably a commercial message direct from the authors, not an accurate representation of the paper itself. Medical journalists are supposed to interpret the findings of recent medical publications and present them to the general public in ways that they can understand. They are supposed to provide context for the discovery, explaining what it might mean for disease treatment or cure. Yet, they rarely do. Instead, they simply copy the press release.
Most people are unaware that scientists issue press releases about their work and they are certainly unaware that medical journalists often copy them word for word. Instead of presenting an accurate representation of medical research, medical journalists have become complicit in transmitting inaccurate or deceptive “puff pieces” designed to hype the supposed discovery and hide any deficiencies in the research.
Imagine if a journalist reviewing the newest Ford cross-over vehicle didn’t bother to drive the car, but simply copied the Ford brochure word for word. Could you rely on the journalist’s evaluation? Of course not. Yet that is precisely what medical journalists are doing each and every day.
