It is surely the sign of a good discussion when you max-out your blog's commenting system. Turns out Daniel (and maybe others) have tried to post further responses but weren't able, so we'll keep the discussion going here. At any rate, it will be good for the comments to not be attached to an admittedly tendentious entry that, thanks to the dialogue, I feel we've gotten past.
While I have the floor, I should mention my earlier response to the John Hopkins studies, as well as one of several spurnings of Enlightenment rationalism, which has proved at least one point of Pinchbeck/Millinerd agreement.
