 Publishing their results in the 1975 book "The Divided Academy", Ladd and Lipset found that about 46% of professors described themselves as liberal, 27% described themselves as moderates, and 28% described themselves as conservative.They also reported that faculty in the humanities and social sciences tended to be the most liberal, while those in "applied professional schools such as nursing and home economics" and in agriculture were the most conservative.Younger faculty tended to be more liberal than older faculty, and faculty across the political spectrum tended to disapprove of the student activism of the 1960s.
