Of course, there are examples of extremely intelligent individuals with strong religious convictions. But various studies have found that, on average, belief in God is associated with lower scores on IQ tests. “It is well established that religiosity correlates inversely with intelligence,” note Richard Daws and Adam Hampshire at Imperial College London, in a new paper published in Frontiers in Psychology, which seeks to explore why.
It’s a question with some urgency – the proportion of people with a religious belief is growing: by 2050, if current trends continue, people who say they are not religious will make up only 13 per cent of the global population. Based on the low-IQ-religiosity link, it could be argued that humanity is on course to become collectively less smart.
