Hur ser förhållandet mellan intelligens och religiositet ut? Studien ”Average Intelligence Predicts Atheism Rates Across 137 Nations”, publicerad i Intelligence, finner följande samband:

Evidence is reviewed pointing to a negative relationship between intelligence and religious belief in the United States and Europe. It is shown that intelligence measured as psychometric g is negatively related to religious belief. We also examine whether this negative relationship between intelligence and religious belief is present between nations. We find that in a sample of 137 countries the correlation between national IQ and disbelief in God is 0.60.

Resultatet förvånar mig inte. Smarta människor inser i högre grad att religion är ett mänskligt påhitt. De mindre smarta tror mer okritiskt på de sagor de har fått lära sig som barn.
