Update: Although this post was written a while back, people are still finding it and reading it. I have updated it here and there to reflect the post-Trump realities.Right after the 2016 US election, we heard a lot about the "echo chamber" that saw a lot of people talking about issues in social media, but mostly to people of similar beliefs.
Why did neither side have much success persuading people of conflicting beliefs and what should we do differently for the futute?
