From The Problem With All Those Liberal Professors by Cass R. Sunstein. The original research is Homogenous: The Political Affiliations of Elite Liberal Arts College Faculty by Mitchell Langbert

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).

Democrats 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.

The faculties of Wellesley, Williams and Swarthmore are overwhelmingly Democratic, with ratios at or above 120 to 1. At Harvey Mudd and Lafayette, the ratios are 6 to 1. At the U.S. Naval Academy at Annapolis, it is 2.3 to 1; it is just 1.3 to 1 at West Point.

But despite the variability, none of the 51 colleges had more Republicans than Democrats. According to the survey, over a third of them had no Republicans at all.

First, those who teach in departments lacking ideological diversity have an obligation to offer competing views and to present them fairly and with respect. A political philosopher who leans left should be willing and able to ask students to think about the force of the argument for free markets, even if they produce a lot of inequality.

Second, those who run departments lacking ideological diversity have an obligation to find people who will represent competing views — visiting speakers, visiting professors and new hires. Faculties need not be expected to mirror their societies, but students and teachers ought not live in information cocoons.

John Stuart Mill put it well: “It is hardly possible to overrate the value ... of placing human beings in contact with persons dissimilar to themselves, and with modes of thought and action unlike those with which they are familiar. Such communication has always been, and is peculiarly in the present age, one of the primary sources of progress.”

Seems like academia's commitment to diversity is, as it were, only skin deep.
