He insulted me for being stupid, and after having an argument (for the sole purpose of amusing myself), that came up.
I'm not sure if I would have to say, but to make sure you understand that I am not stating the kid is superior to you in any way, although you're the one who made yourself get insulted by his words. That itself could be made to prove that you would be stupid compared to him. It's not hard to get an IQ score of 140, the majority of the population are just hypocritical and reject other perspectives.
IQ tests are a rough estimate to determine the development of youth to examine if they have flaws within their brain, and it's not a test to brag about having a higher Intelligence Quotient than other people because the test is flawed by having a "consistent" scoring system when it's a joke.
"Presidents are intellectual people, you shouldn't judge by appearances." also "Parents are superior to children." Personally I'm uncertain of which age provides more thought on average, but I would state it's the youth because adults have more experience from their childhood perspective thoughts from them being taught in previous generation which creates a one dimensional educational system which there isn't much development because the only growth would be from society acceptable thoughts and not more logical ones. Although adults should have more thoughts than children because they're the ones doing the labor (usually) and they have previous experience to contain a stable education for the young.
I ask why, but you ask how. I would probably say that's the difference at the core, and I'm not sure how people would change because I don't have experience in teaching. There's also only one problem with the world, and it'll stay one long after I'm dead.
In one word, you're the hypocrite, and in a way the kid you were "arguing" with, he was with or without the intention of learning was just in the first place by creating experience. Although the kid has potential to be more, he most likely won't because of education, and that's in my perspective an inevitable problem we've provided for the future. Whether you would agree or not the people who teach currently generally create a future generation of people who follow the instructors teaching and that's also hypocritical. You probably wouldn't fully understand to my extent of what I meant, and I don't blame you either.
