Pat; didn't we have a breakdown of just where the E's and C's fit on a theological rating?
Seems like we took an online survey last year... IIRC.
I don't recall a survey on this website. College graduates are somewhat more likely to be atheists than others, and that's true of scientists as well. But all the articles I've seen on this say that loads of scientists are religious. I don't recall any percentages; but I think it's well more than half. (I'm not speaking of people in the "social sciences" because they're mostly all commie whackjobs.)
As for the evolution ping list, now about 354 names, and virtually all pro-evolution, I think about a dozen or so have declared themselves to be atheists. Far more have said the opposite. The rest haven't said anything on the topic (it's really not relevant in a science thread, notwithstanding your example), so believe whatever you like about them.
