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.
Memorization have importance. We, as a species, are as intelligent as primitive cavemen. Our brains haven’t changed that much since those times.
What allows us to be different, to have a prosper civilization, is the information we have stored. Much of that information is stored in our brains.
Critical thinking is of great importance. Of course. But let’s not dismiss the ability to store that critical information.
Memory is often used as a facade to demonstrate intelligence that lacks thinking, though.
If we define intelligence by the development of the brain’s abilities, memorization is one of those abilities. Then, great memorization would be, per se, a feat of intelligence.
