Our popular economics writers, however, are not in the business of giving their readers a ringside seat on the research action; with no exception I can think of, they use their books to do an end run around the normal structure of scholarship, to preach ideas that few serious economists share. Often, these ideas are not just at odds with the professional consensus; they are demonstrably wrong, and sometimes terminally silly. But they sound good to the unwary reader.

Paul Krugman...academic credentials are neither a necessary nor a sufficient condition for having your ideas taken seriously. If a famous professor repeatedly says stupid things, then tries to claim he never said them, there's no rule against calling him a mendacious idiot - and no special qualifications required to make that pronouncement other than doing your own homework.Conversely, if someone without formal credentials consistently makes trenchant, insightful observations, he or she has earned the right to be taken seriously, regardless of background.
