Nothing is obvious. If you think the solution to some widespread problem is “obvious” and everyone else is simply foolish for missing it, then there’s only one fool in the room, I’m afraid.
People know things because they learn things, and they learn things through effort and challenge. Other than how to walk and eat, virtually no knowledge comes “naturally” to humans. But the brain is a funny thing, and loves to be confident where it shouldn’t be. So your brain will jump with great certainty to “obvious” answers, especially when the risk of being wrong is virtually zero.
(The above paragraph explains why almost all opinions are terrible.)
Experts can lie, and non-experts don’t know anything. So your only reasonable path is to become an expert yourself on things that actually matter, and ignore everything else. It’s hard, but it’s happier.
