Is mathematical ability determined by your DNA? Or, is mathematical ability something that is “learnable”?
Key quote: “…the one key difference between students who are good at math and those who aren’t is simply that their belief in math as genetic, as opposed to a learned skill. Turns out, it’s much like a self-fulfilling prophecy: if you think your abilities in math are determined by your genes, chances are you probably won’t get that far. If you think math is learnable, chances are you’ll end up a calculus whiz.”
