This episode explores the experiences of conservative professors on campus, and why ‘viewpoint diversity’ matters in academia. We hear from Josh Dunn, Professor of Political Science at the University of Colorado and John Shields, Associate Professor of Government at Claremont McKenna College, who co-authored a book on conservative academics. Zack Beauchamp from vox.com joins Arthur in a discussion about de-platforming and freedom of speech on campus, and Professor Robert George talks about his experience at Princeton.
