The report pointed out that 5.8 billion humans, representing 84% of the worldwide population, identify as religious. “While it is generally accepted that religion contours people’s moral judgments and pro-social behaviour, the relation between religion and morality is a contentious one,” it said.

The report was “a welcome antidote to the presumption that religion is a prerequisite of morality”, said Keith Porteus Wood of the UK National Secular Society.

“It would be interesting to see further research in this area, but we hope this goes some way to undoing the idea that religious ethics are innately superior to the secular outlook. We suspect that people of all faiths and none share similar ethical principles in their day to day lives, albeit may express them differently depending on their worldview.”

According to the respected Pew Research Center, which examines attitudes toward and practices of faith, most people around the world think it is necessary to believe in God to be a moral person. In the US, 53% of adults think that faith in God is necessary to morality, a figure which rose to seven of 10 adults in the Middle East and three-quarters of adults in six African countries surveyed by Pew.
