The historical battles between religious institutions and science, such as those in physics, astronomy and biology, indicate there is something wrong with the religious approach to the study of reality. The underlying problem extends to negative effects on the individual intelligence of believers, and a related negative effect on educational achievements. Hardly any of the several-hundred Nobel Prize winning scientists have been Christians. Only 3.3% of the Members of the Royal Society in the UK and 7% the National Academy of Sciences in the USA, believe in a personal God. The more senior and learnéd the scientist, the less likely they are to believe in God. The children of highly religious parents suffer diminished IQs – averaging 7 to 10 points lower compared to their non-religious counterparts in similar socio-economic groups. As you would expect from these results, multiple studies have also shown that IQ is opposed to the strength of religious belief. 39 studies since 1927 (out of 43) have found that the more educated a person is, and the higher one’s intelligence, the less likely someone is to hold religious beliefs – “religion declines in proportion to the rise in education and personal income”1. This correlation isn’t new and was also observed in ancient Greece by Polybius (200-118BCE)2.
The effect extends beyond individual countries and is visible inter-nationally. Countries with a higher rate of belief in God have lower average intelligence. All countries with high average intelligence have low national levels of belief in God. For countries where belief in God is over 80%, the average national IQ is 83 points. For those countries where stated disbelief in God (atheism) is greater than 20%, the national average IQ is 98 points. Instead of belief in God, countries with the highest IQs adhere to Far-Eastern belief systems such as Buddhism, Taoism and Shintoism. It is not just intelligence and education that is inversely correlated with religion – it has also been found that the more you know about religion itself, the less likely you are to be religious3.
