Earlier quoted context omitted.
In other words, our mirror neurons and empathy aren't made for online communication. On the Internet, we're all psychopaths.
> On the Internet, we're all psychopaths. That might be the best one-line summary of the problems with social media I've ever seen.
On the internet, people often are honest, and say what they really think. This reflects their (often divergent) beliefs about the world.
Again, in the context of meta-discussions like this, most people do not know what a belief is. For example, it does not mean only religious belief. It does not mean "a false idea that someone else has". Beliefs are actually foundational concepts and viewpoints in everyone's brain.
And the most core beliefs are generally reductionist regardless of who you are. Think about looking off into the distance. You can't have an infinite concept of what's out there so it all fades to a point.
A big part of the problem in many of these online conflicts is that the opposing parties are effectively occupying different realities. But even more difficult is that each is 100% certain theirs is the correct version. And even more difficult is the fact that as I said, they don't understand this concept of worldview or realize that no worldview is perfectly accurate. Actually most don't understand the difference between a worldview, a normal viewpoint, and a true fact about the universe.
Even more difficult is the fact that worldviews are closely linked to group identity. So much of the behavior is raw tribalism (trying to protect/promote your own group subconsciously) attached to worldviews, but the people think they are just defending true facts about the world.
