Reader demographics

The commercial success of anti-religion books has gotten a bit of attention (here’s a Freakonomics post for instance), and here is a piece in The Weekly Standard offering up its explanation. The part that made me pause is this passing comment:

We know from behavioral studies that, to the embarrassment of atheists, believers, or at least churchgoers, are better citizens–more active and law-abiding–than those who spend Sunday morning reading the New York Times.

Is reading the Sunday Times a proxy for atheism?
