I didn’t think it possible, but this article on the work of anthropologist James Dow actually makes Richard Dawkins’s take on religion sound subtle:

God may work in mysterious ways, but a simple computer program may explain how religion evolved.

By distilling religious belief into a genetic predisposition to pass along unverifiable information, the program predicts that religion will flourish. However, religion only takes hold if non-believers help believers out–perhaps because they are impressed by their devotion.
