Answer:
Both Cass Sunstein and Julian Sanchez are scholars who have written about the effects of the internet on democracy and public discourse. They share a common concern that the internet, especially social media, can create echo chambers and filter bubbles that isolate people from diverse and challenging views, and make them more susceptible to misinformation and conspiracy theories1234. They argue that this can undermine the quality of democratic deliberation and the common ground that is necessary for a healthy society. They also propose some possible solutions, such as encouraging exposure to different perspectives, promoting critical thinking, and fostering online civility.
