ABSTRACT: Conservatives in the United States have grown increasingly critical of universities and their faculty, convinced that professors are ideologues from the political left. Universities, for their part, have increasingly adopted a mantra of diversity and inclusivity, but have shown little interest in diversifying the political and ideological profile of their faculties. This essay argues that the lack of political diversity among American university faculty hampers the ability of universities to fulfill their core mission of advancing and dissemination knowledge. The argument is advanced through a series of four questions: Is it true that university faculty are not ideologically diverse? Why might it be true? Does it matter? How might it be fixed.
