I found this comment from Digg to be interesting:

There was a study done years ago looking at IQ in Japan, and it found Catholics were the most intelligent. This would seem to apply the reverse trend applies with the Japanese... but in fact it doesn't. Japan is a culture that is mostly agnostic/atheist; those who are religious had to seek out and study it themselves. Likewise, the USA is a conservative/religious western nation. Thus those who embrace atheist/liberal ideas most likely weren't brought up in that environment but had to seek out those ideas and embrace them themselves.

Put in another way... those who are less intelligent will simply adhere to the cultural ideas/traditions without questioning them. Those who are more intelligent will question them, and may or may not agree with the cultural ideals/traditions. Thus, in the USA, those who are conservative/religion include the less intelligent and the more intelligent who came to the same conclusion. Those who are liberal/atheist include mostly those more intelligent who didn't come to the same conclusion.

This is the study:
