In certain departments, Republicans are literally nonexistent. There are no Republicans in either the anthropology or sociology departments at Stanford or UC-Berkeley. At Berkeley, the ratio of Democrats to Republicans is 11 to 1 in the economics department and 14 to 1 in the political science department. Stanford is a model of intellectual diversity by contrast, with a Democrat/Republican ratio of 7 to 3 in economics and 9 to 1 in political science.Moreover, the bias among the faculty is self-reinforcing due to the tenure system of US universities. It is incredibly difficult, if not outright impossible in some departments, for an academic with non-progressive credentials to get hired or to get tenure.
In a larger study, Klein looked at voting patterns from a survey of academics throughout the country. He found that in anthropology, there are more than 30 votes cast for Democratic candidates for each 1 cast for a Republican. In sociology, the ratio is 28 to 1. Republicans do best among economists, who only vote Democratic by a 3 to 1 margin. In political science, the ratio is 6.7 to 1. On average, across all departments, Democrats get 15 votes for every 1 going to Republicans.
And the hiring process is unlike anything in a private business. In most cases, one needs a unanimous vote of the professors in ones department to get tenure. This puts a high priority on intangibles like collegiality, which often translates into sharing the same politics and ideology.If the point of universities is to provide a "marketplace of ideas", they are failing miserably.
Bias works in other ways as well. It is extraordinarily difficult to get an article in a top academic journal or get a book published by a university press unless it slavishly parrots the liberal line. That is because such things must be peer-reviewed by experts in the field before they can be published. This makes it very easy for anonymous reviewers to blackball those with a conservative point of view, effectively killing the careers of those who must publish or perish.
