Polarization Feels Unstoppable. Will it Destroy Democracy?
In this episode of At the Boundary, we explore how America’s deepening divides are shaking the very foundations of democracy. Dr. Josh Scacco—USF’s first-ever Carnegie Fellow and founding director of the Center for Sustainable Democracy—joins us to dissect the troubling link between political polarization, public trust, and national security. From social media echo chambers and disinformation to local political violence and eroding public health consensus, Scacco explains why polarization feels so relentless—and what it could ultimately cost us.

He also reveals his new research on vaccine attitudes in Latino and Hispanic communities, showing how polarized messaging threatens long-term democratic resilience. Most importantly, we discuss practical ways to rebuild trust and civic engagement, starting close to home. If you’re concerned about America’s democratic future—or just curious about how communication shapes the security landscape—this is an episode you won’t want to miss.

At the Boundary from the Global and National Security Institute at the University of South Florida, features global and national security issues we’ve found to be insightful, intriguing, fascinating, maybe controversial, but overall just worth talking about.
A "boundary" is a place, either literal or figurative, where two forces exist in close proximity to each other. Sometimes that boundary is in a state of harmony. More often than not, that boundary has a bit of chaos baked in. The Global and National Security Institute will live on the boundary of security policy and technology and that's where this podcast will focus.
The mission of GNSI is to provide actionable solutions to 21st-century security challenges for decision-makers at the local, state, national and global levels. We hope you enjoy At the Boundary.
