If tutors really do reliably produce two-sigma learning gains, then why aren't most top achievers the product of tutors? Yes, they're expensive, but perhaps "only" 2-3x private school; there are a lot of wealthy parents. Diminishing returns for high achievers?

Interestingly, most (all?) top achievers in athletics and conservatory music are tutored. Why is this not true of most fields? Is it that music/athletics have so much more tacit knowledge? Or by contrast is so much more legible, so that a tutor/coach can be much more effective?

“conservatory music” means performance? performance seems like a fundamentally different thing from creativity; wouldn’t make sense to me to compare this to e.g. science. but composing music would make sense as a comparison. are top composers tutored? probably not?
Right. And athletes are all playing the same game with the same rules.
In science and creative work, the rules and methods are constantly changing.
