Michael Brooks, writing in The New Scientist, says,

Bering considers a belief in some form of life apart from that experienced in the body to be the default setting of the human brain. Education and experience teach us to override it, but it never truly leaves us, he says. From there it is only a short step to conceptualising spirits, dead ancestors and, of course, gods, says Pascal Boyer, a psychologist at Washington University in St Louis, Missouri. Boyer points out that people expect their gods’ minds to work very much like human minds, suggesting they spring from the same brain system that enables us to think about absent or non-existent people.

The ability to conceive of gods, however, is not sufficient to give rise to religion. The mind has another essential attribute: an overdeveloped sense of cause and effect which primes us to see purpose and design everywhere, even where there is none. “You see bushes rustle, you assume there’s somebody or something there,” Bloom says.

…even adults who describe themselves as atheists and agnostics are prone to supernatural thinking. Bering has seen this too. When one of his students carried out interviews with atheists, it became clear that they often tacitly attribute purpose to significant or traumatic moments in their lives, as if some agency were intervening to make it happen. “They don’t completely exorcise the ghost of god – they just muzzle it,” Bering says.

Brooks has been known to comment on Robin Hanson’s Overcoming bias blog.

I should mention that I think that atheists are susceptible to state-worship. As a result, the disposition to believe in the supernatural gets exploited by politicians.
