In response to my article on citations as a measure of faculty quality, several Ricochet members rightfully commented that this approach could allow the liberal bias in universities to entrench themselves. Liberal academics might boost their numbers by choosing to cite each other -- you often cite things you agree with, and one could strategically cite only other liberals to advance their careers and one's own.
This might be going on, and I tended to doubt it. That was, until I read this post by David Lat over at Above the Law, which shows a deliberate liberal bias in a leading law journal in selecting articles. Lat posts leaked emails between the student editors that seem to show a rejection of an author because of his conservative c.v. If true, this only shows yet again that the system for hiring and promotion at law schools, which is based primarily if not exclusively on publications, suffers from an intentional, conscious bias against conservatives. (Of course, this might be a good reason for law, like most other scholarly disciplines, to have journals where other professors select the articles, rather than students -- but this might also make the bias worse).
