Of the many differences between the West and the rest of the world the issue of religiosity is one of the most striking. In the West ever fewer people belong to a religion – the number for the UK is now around 50% - and in the US around a third of people are religiously unaffiliated. But elsewhere in the world religions are growing – and in the world as a whole nearly 90% of people are religious. Robin Dunbar – Professor of Evolutionary Biology at Oxford University has been thinking about the reason for religion’s appeal for his book How Religion Evolved and Why it Endures (Oxford UP, 2022).
