Religion, spiritual practices, and faith are easily observable factors in the daily lives of people almost anywhere in the world. This leads many to speculate and theorize about the role of religion in driving economic and social outcomes. Positive correlations abound between religiosity and a host of factors that may influence economic success. Correlation, however, does not imply causation and pinning down the real causal relationship is complicated by the fact that people tend to choose their religion. Therefore, observing that people of faith experience different economic outcomes fails to account for the fact that unobservable personal characteristics may cause both religiosity and economic outcomes.
