I mean, we have good evidence that "New Math" pedagogical approach in the 70s was very ineffective compared to traditional learning by example, memorizing multiplication tables at younger ages. Would you say that is "gibberish" as well?
> In reality math teachers who are good are extremely rare because people who are good at math tend to not be teachers.
It's hard to take your argument seriously when your own sentence corroborates what I'm trying to convey.
You could say that not every adult, 2 deviations from the IQ median for the sake of rigor (we lose 2.5% of the population under), capable of reading might be able to follow it, and I would accept the argument. At the same time almost every adult was also indoctrinated in such a way they "hate maths", even though their only experience is dealing with numbers, operations and memorizing formulas that might eventually be useful.
I'm not sure this translates well, but the best allegory I could make to illustrate my point is "the fish does not think about the water".
I am fine with the research results, it's important to note that it does not control for pedagogical variance. [Edit: I'd like refer to the last 2 paragraphs on the Discussion section to point out other issues in the paper the author acknowledges]
One speculation I'd be fine to make would be that high IQ could be associated with survival bias, e.g. someone who is already quite adept at identifying patterns might be able to derive meaning from structures without requiring the motivation that compounds over time for others "less gifted". But I am happy to accept it's just a very convenient speculation.
Sure, Terence Tao might be a gifted unicorn with a special brain, he had of course the circumstance and means to have his potential thoroughly leveraged. Maybe someone "gifted" that is forced to memorize the quadratic formula to pass a test gets bored (but not gifted or motivated enough to complete the square on their own).
Edit: I agree with the rigor on "everyone" and "maths" (not everyone, not all maths), I hoped we had shared context on this basic assumption (which I expected to be a frivolous pedantism, I stand corrected nevertheless). I also appreciate the point about cruelty (which, in the schooling context, I believe goes beyond just our specific topic) but this textbox is too small to contain my wonderful argument.
You are being disingenuous. Of course people with disabilities or severely deficient in cognition have innate difficulties that might hamper or completely preclude the development of mathematical skills.
The main point is that the educational environment most people have to deal with: public school in most countries, focused on rote memorization of formulas for passing tests, is the main factor on the incredibly inefficient and adversarial perception of most students and adults.
If you are able to understand something as "basic" as higher order effects in economics and societies, accrued from an understanding of rates of change from calculus, you are of course extremely privileged. On the other hand you are not some gifted unicorn with a special brain, you are just lucky (exceptions exist, but even they have to be somewhat lucky).
A bit of a tangent, but the more complete reason depends on what civilization (Aztecs/Incas), the common factor is an extreme loss of life due to old world disease.
Additionally, for the projectile velocity at the time the gambeson-like garment the Aztecs had available was surprisingly effective.
