Also at the Acton Institute blog is a discussion of a recent MIT study that says that weekly church attendance raises your income 10 percent. I have to wonder whether they’ve fallen for the causation fallacy, i.e. that two data points don’t necessarily indicate causation rather than correlation. In other words, it may not mean that if someone wants to raise their income that going to church will help.
Instead, I think it shows that people who go to church on a regular basis are often people with those certain qualities that make them more economically productive. You have to be a certain type of person to both go to church on a regular basis and be more economically productive.
To use a familiar analogy, it would be like finding out that 90 percent of driveways in your neighborhood have expensive cars in them and deciding to park your car in your driveway expecting it to become a a luxury car.
