This is true in so many areas of journalism but lately seems especially egregious in the NYT. And I don't really blame them, as the incentives for any individual reporter are just too great - having the government make a major policy change based on your article is basically the brass ring for an investigative reporter.
I basically can only use these types of articles as a jumping off point for my own research, as I usually find the moralizing conclusion the article comes to as unsupported.
