Exactly. Information is not the problem, or at least not the most fundamental one. The problem is that humans have a natural bias towards believing anything that agrees with one's existing worldview, and a natural bias against believing anything contrary to that worldview. In short, the underlying problem really is a function of how our brains work. Social media may not be the cause, but IMO it's definitely not helping either. In the past, the kinds of political disagreements you see on social media would almost always have happened in person instead (or over the phone at least). I suspect most people find it a lot easier to be a jerk online than in person.
