John Sides defends political science:

Let’s leave aside the notion that “multiple regression analysis” is the “only legitimate tool.” That’s the impression of someone who doesn’t read much political science. I’m more interested in Middle East peace. Here’s my question: if Hayward picks up the American Economic Review, does he envision that their mathematical formulas will produce global prosperity? That’s the standard to which he seems to hold academic research. If so, he should be disappointed by virtually the entire corpus of social science, and perhaps by a decent bit of the hard sciences as well. After all, there’s still that cancer thing.
