The IQ differences, while statistically significant, are not stunning -- on the order of 6 to 11 points -- and the data should not be used to stereotype or make assumptions about people..suggesting that religious and social decision making for humans, is not all genetically programmed. To me IQ or any other quotient, describes the effect of training on our genetic makeup. That is also the fundamental origin of the limitations quoted above.
This analysis is exciting, because it allows an avenue to think of the problem of why science largely stays out of our society. What forces people to read or hear about that bridge or whatever NASA imaged around North-west Sri Lanka and think of some religious fundamentalism and not realize that the thought process is 'unscientific'?
