The Dunning-Kruger Effect Does Not Explain “Why Society Is So Screwed-Up”

Besides being simplistic, your assertion is also a perfect illustration of the Dunning-Kruger effect. Is it possible that you have not read enough articles about the issue? Because, as you say: “This is also commonly seen on social media, where people share their ideas as if they were experts. In reality, many of the noisiest on Twitter, Facebook, Reddit, etc. have only read an article or two, saw another user’s video, or browsed comments.” Should we add Medium to that list?

It seems that today we can no longer meet each other at even some basic level of respect, but must always diagnose each other instead.

While that doesn’t explain why society is so screwed-up, perhaps its a start.
