Recently, we looked at a claim, published in a serious science journal, Intelligence, that belief in God correlates worldwide with lower IQ. From the same journal in the same year, we learned that religion correlates with lower IQ among American teenagers.
If half of the Catholics and Baptist teens are sporadically observant and doctrinally indifferent (no unusual state of affairs), religious orthodoxy collapses as a predictor of IQ. So it is not clear just what Nyborg is measuring. Social class is a possibility.More.
