Correlation is not causation:
[Researchers] combined 25 indicators of societal and economic stability — things like crime, suicide, drug use, incarceration, unemployment, income, abortion and public corruption — to score each country using what he calls the “successful societies scale.” He also scored countries on their degree of religiosity, as determined by such measures as church attendance, belief in a creator deity and acceptance of Bible literalism. Comparing the two scores, he found, with little exception, that the least religious countries enjoyed the most prosperity. Of particular note, the U.S. holds the distinction of most religious and least prosperous among the 17 countries included in the study, ranking last in 14 of the 25 socioeconomic measures.
How could that be? We’re the richest country in the world! Right?
