“Religious people branded as less intelligent than atheists…That’s the provocative conclusion of a new review of 63 studies of intelligence and religion that span the past century. The meta-analysis showed that in 53 of the studies, conducted between 1928 to 2012, there was an inverse relation between religiosity — having religious beliefs, or performing religious rituals — and intelligence. That is, on average, non-believers scored higher than religious people on intelligence tests.”
If you are an atheist, you probably already knew this, being intelligent an all (and you were probably aware of at least one of the previous studies). If you are a religious person, you will reject the findings. For me, I’m not quite either, I would add a reason religious people are less intelligent than atheists (and other non-religious people) to those given in the Huffington Post article by the scientists; many religious leaders tell their flock not to question. Questioning engages the brain whereas acceptance without thought just numbs it.
