#Republic: Divided Democracy in the Age of Social Media
Sunstein, Cass R. #Republic: Divided Democracy in the Age of Social Media. Princeton, NJ: Princeton University Press, 2017.
Why this matters here
Sunstein analyzes how social-media filtering and like-minded networks can reinforce polarization and confidence. The chapter cites that argument to distinguish platform-shaped amplification from careful evaluation of representative evidence; its broader criticism of certainty remains the author's.
