ABSTRACT

Many studies have found inverse correlations between intelligence and religiosity, intelligence and political conservatism, and intelligence and political extremism. Other studies have found that academics tend to be significantly less religious and more liberal than the general population. In this article, we argue that interdisciplinary differences in religiosity and political perspective among academics are predicted by interdisciplinary differences in intelligence between academics. Once personality factors correlating with religiosity have been substantially controlled for, physicists, who have higher average intelligence, are less religious than are social scientists, who have lower average intelligence. Physical scientists are also less politically extreme than are social scientists.
