A talk with David Foster, who writes about polarization and media at knowthesystem.org and is the author of "Moderates of the World Unite!: Reworking the Political Media Complex." Topics discussed include: the optimal approach for reducing toxic political polarization (cultural change vs systemic changes); defining the word 'moderate' and examining some of the negative connotations it has; the difficulty of making changes in a polarized, high-animosity environment; why some conservatives dislike the idea of making systemic changes; the ideas in David's book for improving the media environment and political discourse. ------------------------------------------------------ Support the show To get ad-free episodes, and more, get a premium subscription.
