We must use our brains to overcome our brains. You are the solution to this crazy world we find ourselves in. Do everything you can to reach others. … - Guy P. Harrison

Humility is the key. If you are an arrogant, condescending skeptic then you are doing it wrong. Science and critical thinking rest upon a premise that says anyone can be wrong about anything. A good thinker is humble. We also must be mindful of the fact that very intelligent people can hold very dumb beliefs. It's a human condition. Irrational believers are not inferior people; they simply made a misstep somewhere along the way in their thinking.

The crucial ever-present factor in 2020 was critical thinking. Those who thought well were less likely to tumble into the rabbit holes of QAnon, COVID is a hoax, 5-G towers help spread the virus, racism is scientific, hydroxychloroquine cures COVID, demon sperm is a problem, tracking devices are in vaccines, mass election fraud, etc. The ability and willingness to lean toward evidence and logic rather than side with blind trust and emotion was the key metric behind the madness.

The world's biggest problem is not sexism, racism, political polarization, war, or income inequality. The key never-ending crisis is that most people can't or won't think. Poor thinking skills cut cross all the usual lines to drag down societies like nothing else. Thinking well could alleviate or solve virtually all our problems.
