IIRC there's a fairly strong correlation between content mastery and teaching ability, even at the high school level, far more than the correlation between level of teacher training and teaching ability.

Obviously there's other factors (effort, as you point out).

Though I think it's partly an artifact of the days when an undergrad degree would bring students to the leading edge of research, so there was simply no-one else qualified. There would have been a lot more synergy when researchers were explaining cutting edge ideas to students (it still happens a bit, but it's the exception rather than the rule).

Yes, that was my suspicion too -- historically, students were only going to those lectures where they were actually interested and which they were much closer to the level of the lecturer. In that case, the bottleneck isn't "ability to be a good explainer to novices" but "ability to answer arbitrary questions".

IOW, it looked more like grad school today, where the good researchers naturally are a better fit for teaching, and don't mind it as much.
