Authorities in America have traditionally left governance of pubic universities to faculty and administrators, under a presumption of academic freedom and an apparent trust that all was well. This hands-off policy persisted as radicals virtually extinguished intellectual pluralism. Throughout the process, the NAS has seen successes in a campaign to preserve the marketplace for divergent ideas, but now we're on the offensive locally with an arsenal of statistics and a preponderance of evidence on the effects of political lopsidedness in the academy. When Pennsylvania legislators requested a briefing on how things stood on their campuses, NAS president Steven H. Balch obliged with persuasive testimony about the shrill advocacy and activism that incline women's studies, schools of social work, ed schools, and many other departments and programs in Pennsylvania's public system tendentiously leftward, away from the intellectual free-for-all that is a hallmark of the dispassionate pursuit of truth.
