Since skepticism is indeed logically compatible with atheism, how is it that so many theists are convinced to accept claims for a deity for which there is no good evidence? Why is it that theists are more likely than atheists to be political and social conservatives? Why is it that theists are more likely than atheists to be denialists of science in general and of global warming in particular?
The answer, I think, is not merely that theists are statistically more likely than atheists to score lower on IQ tests or to lack a good education in science. The answer, it seems to me, is that conservative theists are more likely than liberal atheists to have inherited the equivalent of a 'selfishness gene' that makes them prone to favor emotionally appealing, though unsupported and illogical, arguments.
