>The vast majority of people are not biologically incapable of making it through high-school level math, or even becoming a very capable mathematician with enough high-quality teaching and dedication.

It was hard for me to accept, but I know that after many years of University math education there are things I will never be able to understand. I have had very good grades in my Masters, but I realized that I will never be able to do research in pure mathematics.

Almost every person I know struggled with math far more than I did. How would they become research mathematicians if I couldn't after years of study? The belief that secretly almost all people are better at mathematics than me, despite me trying for many years, seems utterly absurd.

Do you think I really am in the bottom ~50% of the population in terms of mathematical ability? Because I know I will never be a pure mathematician.
