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.
Intelligence is such an elusive concept, but here goes anyway…
Knowing stuff makes you knowledgeable. You’re either born intelligent, stupid or somewhere in between. No amount of studying will ever change that, unless studying also involves copious amounts of alcohol. In that case, you’ll only get dumber.
Anyway, studying gives you information and tools, and what you’re talking about is a bit of both. If you go through a training system like that, you’ll be equipped to process and evaluate information, but none of that changes how intelligent you are. Sure, you can sound really smart to other people by using fancy terms and explaining complicated things. Those words alone don’t make you intelligent. Having the innate ability to understand that level of information does.
I’m sure there are really smart people living in rural parts of India where they don’t learn to read or even count very far, but they can do really clever stuff when hunting birds or weaving baskets. Even though they didn’t receive much education beyond what they learned from the local villagers they can still be intelligent. If they were born in a wealthy family in UK, these people would probably go to Oxford and graduate with a PhD in no time.
I’m not saying people without formal education don’t have the capacity for intelligence, I’m saying education increases intelligence through reevaluating your own thoughts.
From what I recall, it’s generally accepted that your potential for intelligence is based primarily on your genetic luck and environmental factors. Your genetic potential being how well your biological processes work, the hardware you’re given, and then environmental factors like injury, nutrition, and education that determine how much of your potential you reach or are hindered from.
If there were 2 clones, one born to a rich family with high IQ parents that understand how to nurture intelligence and one born to 2 mentally challenged parents who not only lack the ability to take care of their kid properly but require their kid to take on a caregiver role as a child. 99% of the time, one of them would reach their full potential while the other wouldn’t.
