Suppose that you start college with a keen interest in physics, and you quickly discover that almost all members of the physics department are Democrats. Would you think that something is wrong? Would your answer be different if your favorite subject is music, chemistry, computer science, anthropology or sociology?
In recent years, concern has grown over what many people see as a left-of-center political bias at colleges and universities. A few months ago, Mitchell Langbert, an associate professor of business at Brooklyn College, published a study of the political affiliations of faculty members at 51 of the 66 liberal-arts colleges ranked highest by U.S. News in 2017. The findings are eye-popping (even if they do not come as a great surprise to many people in academia).
Cass SunsteinDemocrats dominate most fields. In religion, Langbert’s survey found that the ratio of Democrats to Republicans is 70 to 1. In music, it is 33 to 1. In biology, it is 21 to 1. In philosophy, history and psychology, it is 17 to 1. In political science, it is 8 to 1.
The gap is narrower in science and engineering. In physics, economics and mathematics, the ratio is about 6 to 1. In chemistry, it is 5 to 1, and in engineering, it is just 1.6 to 1. Still, Lambert found no field in which Republicans are more numerous than Democrats.
True, these figures do not include the many professors who do not have a political affiliation, either because they are not registered at all or because they have not declared themselves as Democrats or Republicans. And, true, the ratios vary dramatically across colleges.
