When surveys of faculty tell everyone that politically right-of-center voices are now much reduced or even in certain areas largely absent, people can be sure that the academy is damaged in at least one respect: the campus political and social climate will be unrealistic. Programs where this is central, such as political science and sociology, will be damaged most, but its effect will be felt throughout the humanities and the social sciences. The kind of damage the author attempts to talk about goes deeper than this--and that is the damage done more generally to the quality of teaching and research when the campus is so politically one-sided. In this article, the author explains how political one-sidedness damages the quality of teaching and research in campuses. (Contains 6 notes.)
