The question of why economically developed countries turn to atheism has been batted around by anthropologists for about eighty years. Anthropologist James Fraser proposed that scientific prediction and control of nature supplants religion as a means of controlling uncertainty in our lives. This hunch is supported by data showing that the more educated countries have higher levels of non belief and there are strong correlations between atheism and intelligence (see my earlier post on this).
Atheists are more likely to be college-educated people who live in cities and they are highly concentrated in the social democracies of Europe. Atheism thus blossoms amid affluence where most people feel economically secure. But why?
It seems that people turn to religion as a salve for the difficulties and uncertainties of their lives. In social democracies, there is less fear and uncertainty about the future because social welfare programs provide a safety net and better health care means that fewer people can expect to die young. People who are less vulnerable to the hostile forces of nature feel more in control of their lives and less in need of religion.
