Why is the academy dominated by liberals?

Hence the purpose of this book: to examine standard rationales for an occupation that pledges diversity and tolerance but has ended up so dominated by the left half of the ideological spectrum. Gross combines existing data with his own Politics of the American Professoriate project, which queried 1,416 professors in different disciplines and types of institutions for, among other things, their political self–conception. The results provide an empirical base on which he evaluates theories about the conservative mindset, discrimination in hiring, indoctrination in the classroom, and just how liberal the faculty really are.
