There's tons of exceptions. But there's a reason people who graduate with teaching degrees have the lowest SAT scores of pretty much any major/discipline.
Not denying the validity of that but if we agree that “teaching” as the ability to relay unintuitive concepts in a way relevant to the student, there’s not an section on standardized tests where that burgeoning skill would be detectable.
A teacher obviously has to have some baseline level of intellect/subject knowledge but so much of teaching is everything else (eg pertinent examples, optimally sequencing lessons, illustrating how things fit together etc).
Anecdotal but similarly in sports it seems like many of the best coaches were career role players and given their lesser talent, have a much better understanding of the myriad techniques that aided their development. Whereas someone like lebron (not saying he’d be a bad coach) is so inherently talented he probably has less of a grasp on communication because it comes so naturally. The passing reads he was making as a junior in high school were more advanced than most of the NBA today lol.
And learning is exponential so I don’t think it’s a teacher job to lead you all the way there just far along enough so anyone with enough aptitude can figure out the rest themselves. I could just be trying to further validate my belief but I almost think it’s dangerous to inherit the entirely of someone else’s knowledge since every view we develop is influenced to some extent by our own life experiences. Also just for diversity of thought
