It was a faustian bargainand it certainly made editors at National Public Radio squirm. The deal was this: NPR, along with a select group of media outlets, would get a briefing about an upcoming announcement by the U.S. Food and Drug Administration a day before anyone else. But in exchange for the scoop, NPR would have to abandon its reportorial independence. The FDA would dictate whom NPR's reporter could and couldn't interview. My editors are uncomfortable with the condition that we cannot seek reaction, NPR reporter Rob Stein wrote back to the government officials offering the deal. Stein asked for a little bit of leeway to do some independent reporting but was turned down flat. Take the deal or leave it. NPR took the deal along with reporters from more than a dozen other top-tier media organizations, including CBS, NBC, CNN, the Washington Post, the Wall Street Journal and the New York Times. This kind of deal offered by the FDA - known as a close-hold embargo - is an increasingly important tool used by scientific and government agencies to control the behavior of the science press. By using close-hold embargoes and other methods, the FDA, like other sources of scientific information, are gaining control of journalists who are supposed to keep an eye on those institutions. The watchdogs are being turned into lapdogs. It is hard to tell when a close-hold embargo is afoot because, by its very nature, it is a secret.
