John Lott writes in Barron’s that we should be sceptical of the populist economics trend that’s been prevalent in the past few years. Specifically, Lott criticizes Steven Levitt and Stephen Dubner, authors of Freakonomics, for peddling a kind of “naïve economics” that fascinates readers, but doesn’t hold up to serious scrutiny (rather than “naïve economics,” maybe “economics for the naïve” would be better).
I’ve been working through some similar ideas myself, especially in a new paper criticizing aspects of the pop econ literature. I should point out that these books—including Freakonomics and its many imitators—do have a reasonable goal, namely, to bring the economic point of view to the general public. Now, the fact that economics needs a special literature to explain its ideas to the public is telling, and to some extent an indictment of how the profession has developed (e.g. into an abstract and often excessively technical discipline). Still, as writers like Hazlitt show, it’s a great advantage to be able to communicate economic ideas simply and powerfully. But while in general we should welcome economic writing for non-economists, too often pop econ forgets to stop when descending the ivory tower, and ends up on the intellectual parking sublevel.
