Is There a Liberal Bias Among American Professors?

Democrats dominate academia across nearly all disciplines.

The researchers obtained data that allowed them to calculate the Democrat to Republican ratio (D:R) across all 11 institutions and broken down by faculties and disciplines. For example, common wisdom suggests that professors in the social sciences and humanities are particularly likely to be left leaning. Here are some of the key results (as reported in Tables 2, 3, and 4 in the article on pp. 243 and 246-247):

Broken Down by Institution

UC Berkeley 8.7 (adjusted to account for a less comprehensive dataset)
UCLA 7.2
Stanford 6.7 (adjusted to account for a less comprehensive dataset)
UCSD 6.6
Santa Clara 6.0
Caltech 4.2
SDSU 4.1
USD 3.6
CMC 1.8
PLNU 1.0
Pepperdine 0.9

The D:R across all 11 schools was 5.0. In Table 1 of their article (p. 239), Cardiff and Klein report D:R ratios for several other studies spanning universities and colleges (across a broader range of geographic areas). In all cases, Democrats dominate academia in profound ways ranging from a low of 1.6 to 75 (depending on the study in question).

Do you think that the ratio changes as a function of a professor's faculty/discipline? The short answer is an emphatic yes!

Broken Down by Faculty Type

Humanities 10.0
Arts 7.6
Social Sciences 6.8
Hard Sciences/Math 6.3
Medicine/Nursing/Health 4.8
Social Professional 4.4
Engineering 2.5
Business 1.3
Military/Sports 0.7

Broken Down by Department

Sociology 44.0
Ethnic Studies 16.3
Performing Arts 16.0
Neurosciences 13.1
Languages & Literature 11.9
Psychiatry 11.8
History 10.9
Biology 10.7

Physical Education 1.1
Information Systems 1.1
General Business 1.0
Finance 0.5
Military Science 0.0

Thus, in 39 out of 42 disciplines, the D:R ratio is greater than 1. Of note, the psychology D:R was 8.0 (see the bolded row in the list immediately above). Not surprisingly, psychologists are quite liberal in their political views but not nearly as much as sociologists!

What are your thoughts regarding these findings?

Note: My apologies for the slight misalignment of the numbers in the latter lists. It's tough to get these perfectly aligned via the Psychology Today interface!
