A propos my observation last week that academic law has more conservatives and libertarians than academic philosophy, along comes this study, which doesn't cover philosophy (but one can infer the likely result):

We investigate the voter registration of faculty at 40 leading U.S. universities in the fields of Economics, History, Journalism/Communications, Law, and Psychology. We looked up 7,243 professors and found 3,623 to be registered Democratic and 314 Republican, for an overall D:R ratio of 11.5:1. The D:R ratios for the five fields were: Economics 4.5:1, History 33.5:1, Journalism/Communications 20.0:1, Law 8.6:1, and Psychology 17.4:1. The results indicate that D:R ratios have increased since 2004, and the age profile suggests that in the future they will be even higher. We provide a breakdown by department at each university. The data support the established finding that D:R ratios are highest at the apex of disciplinary pyramids, that is, at the most prestigious departments.

These results are not surprising, given that the Republican Party is now nothing more than a FOX-created freak show.  But the variation by field is telling:  economists have many more Republicans because they are in the grips of a theoretically coherent but false world view about markets and regulation that make support of Republicans instrumentally rational against that background worldview (academic law is parasitic on this).   "Journalism/communication" is not a Wissenschaft, so put that to one side.   Most parts of current academic psychology mimic and sometimes live up to wissenschaftlich standards, but nothing about the field's self-conception as a scientific discipline would lead anyone to think Republicans are anything other than a fringe party.  My guess would be that academic philosophy is closer to Psychology than Law, but if anyone looks at the facts about party registration let me know.  Unnoted in studies like this is that the Republican Party in the U.S. is now a radical outlier, a "freak show" as I've put it.  The old Republican Party now occupies the Democratic Party, which still also has its liberal, FDR wing.  The current official Republican Party is, as Donald Trump has made finally clear, a deranged amalgamation of the pathologies of capitalism in America in the early 21st-century.
