S2 Episode 41: Can Universities Change Without Government Intervention? | Mary Kate Cary

How can universities rekindle public trust and foster genuine viewpoint diversity, without relying on government mandates? 

Today’s guest is Mary Kate Cary, adjunct professor at the University of Virginia (UVA), seasoned presidential speechwriter, and co-chair of Heterodox Academy’s campus community at UVA. John Tomasi and Mary Kate examine the urgent need to move beyond top-down reforms and build cultures of open inquiry from the ground up.

Drawing on recent Gallup polling that shows public confidence in higher education has plummeted from 60% to 32%, Mary Kate argues for bottom-up solutions rooted in the distinctive ethos and history of each campus. She shares examples of innovative, student-facing programming at UVA, such as “Think Again,” “Free Speech Fridays,” and “Disagree with the Professor,” that encourage intellectual humility, critical thinking, and constructive disagreement.

The conversation provides actionable insights for faculty, administrators, and students committed to strengthening open inquiry and viewpoint diversity, highlighting the role of both faculty leadership and supportive administration in achieving durable change.

Mary Kate Cary is Deputy Chief of Staff for Communications and Strategic Initiatives in the Office of the Interim President at the University of Virginia and a long-time advocate for open inquiry, free speech, and viewpoint diversity on campus. She previously served as an adjunct professor in UVA’s Politics Department, where she taught courses on political speechwriting, the greatest speeches in American history, and co-taught a bipartisan election class. Cary is the founding director of Think Again at UVA, a student-facing initiative promoting free speech, critical thinking, and respectful debate, and she co-chairs the HxA Campus Community at UVA, one of the largest chapters of the organization. Before her work in higher education, Cary was a White House speechwriter for President George H.W. Bush and has worked as a political commentator, professional speaker, and writer. She was a recipient of the 2024 Heterodox Academy Open Inquiry Leadership Award for her efforts in advancing open inquiry and constructive disagreement on campus.
