We all know confidently incorrect people. People displaying dunning-kruger. The majority of those people have low education and without someone giving them objectively true feedback on their opinions through their developmental years, they start to believe everything they think is true even without evidence.
Memorizing facts, dates, and formulas aren’t what necessarily makes someone intelligent. It’s the ability to second guess yourself and have an appropriate amount of confidence relative to your knowledge that is a sign of intelligence.
I could be wrong though.
How about we meet in the middle and say “learning the concept that you might be wrong will help your intelligence”?
My mother who “allegedly” graduated high school has more confidence than anyone I know and will say things like “you can’t divide a small number by a bigger number” or “temperatures don’t have decimals, only full numbers”. Then as you stare at her blankly trying to figure out if she’s joking or not, she’ll tell you you’re clearly not very smart if you don’t know that
IMO you’re just describing a closed mind versus an open mind. Learning the concept that you might be wrong is fundamental to having an open mind.
And it’s difficult if not impossible to be more intelligent with a closed mind no?
