There's an article in the current issue of The Economist that you should read carefully: "Trouble at the lab", 10/19/2013. If you're a regular reader of Language Log, you'll be familiar with the issues that it raises — lack of replication, inappropriate use of "statistical significance" testing, data dredging, the "file drawer effect", inadequate documentation of experimental methods and data-analysis procedures, failure to publish raw data, the role of ambition and ideology, and so on.
But all the same, I'm going to push back. The problems in science, though serious, are nothing new. And the alternative approaches to understanding and changing the world, including journalism, are much worse. In fact, some of the worst problems in science are the direct result, in my opinion, of the poor quality of science journalism. One of the key reasons that leading scientific journals publish bad papers is that both the authors and the editors are looking for media buzz, and can usually count on the media to oblige.
