Warning: what follows is a horribly long, inside-baseball post that most people will likely have little interest in reading, and which I had little interest in writing. But it did need to be written. Apologies for the length and the indulgence; we will soon return to our regular programming.

I. Going on the attack is generally more fun, profitable, and attention-getting than playing defense. Politicians know this; athletes know it; even academics know it. Or perhaps I should say that especially academics know it?
Given the nature of the Freakonomics work that Steve Levitt and I do, we get our fair share of critiques. Some are ideological or political; others are emotional.
We generally look over such critiques to see if they contain worthwhile feedback, or point to an error in need of correction. But for the most part, we tend to not reply to critiques. It seems only fair to let critics have their say (as writers, we’ve already had ours). Furthermore, spending one’s time responding to wayward attacks is the kind of chore you’d rather skip in order to get on with your work.
But occasionally an attack is so spectacularly ridiculous, so riddled with errors and mangled logic, that it’s worth addressing.
The following essay responds to two such attacks. The first one was relatively minor, a recent blog post written by a Yale professor. The second was more substantial, an essay by a pair of statisticians in American Scientist. Feel free to skip ahead to that one (at section III below), or buckle up for the whole bumpy ride.
