How the 'propaganda feedback loop' of right-wing media keeps more than a quarter of Americans siloed

Why is there so often no overlap, no resemblance whatsoever between the news events reported in mainstream print and broadcast coverage, and even on liberal outlets like MSNBC, and the topics that get broadcast as news on the Fox network and its fellows on the right? What process lets even the most outlandish conspiracy notions survive and flourish in the right’s echo-chamber ecosystem, in a way they don’t come close to doing elsewhere? Yochai Benkler is a Harvard law professor, the co-director of the university’s center for studying the internet and society, and co-author of a new book with the unmistakably alarming title “Network Propaganda: Manipulation, Disinformation and Radicalization in American Politics.” The book is a work of anatomy, dissecting how this deep disequilibrium is imperiling the nation’s civic and public life. Benkler has also rethought the part that social media play in all of this, beginning with our perceptions of what free speech has come to mean in the age of Facebook and Twitter.
