Wall Street Journal (and not paywalled for me): Why Social Media Is So Good at Polarizing Us. “A growing body of research suggests that social media is accelerating the trend, and many political scientists worry it’s tearing our country apart. It isn’t clear how to solve the problem. And new research suggests that one often-proposed solution—exposing users on the platforms to more content from the other side—might actually be making things worse, because of how social media amplifies extreme opinions.” It was interesting to read this in context with a recent article in Scientific American. I encourage you to read both.
