      [hesitantly raising hand in seminar] do you think ... possibly ... there might be nepotism at work here? is that a thing we should study? or inherited strong networks and superior networking opportunities? but mostly, like, nepotism? [gunshot rings out]https://twitter.com/aaronclauset/status/1375116257473789953 …

      9/ To close: Faculty tend to come from highly educated families. But, for murky reasons: how does a parent’s PhD help a child become faculty, at an elite job? Perhaps identifying with academic ideals? Early opportunities academia values? Role models? 🤷🏼 We’d love to know.

      Tiger parenting, generally much higher value placed on education by parents, and I am sure genetics plays a big role (twin studies). I'd expect much less nepotism in academia than in, say, investment bank:)

      Heritability not strong enough for genetics to play a big role -- corr between parent IQ and child IQ is 22% if they live apart (42% if they live together) which could explain parents of faculty having PhDs at a rate 1.2-1.5x more than general pop, but observed rate is 25x

      This argument smells off to me. If you'll let me make the (ok, insane) assumption that top 1% IQ=you get a PhD, then 0.4 corr means that if your parent has a PhD, you're 8-9x more likely to have one than the general population. If tails are fatter then more extreme..

      You get that result because of your (as you noted, insane) assumption that top 1% of the distribution gets a PhD. Plug in a more realistic distribution and you will get a more realistic result.

          I mean sure, I use that as an extreme example to suggest that a population correlation might not be that helpful for investigating a tail- after all, we're talking about a profession that (hopefully) selects strongly for intelligence. What assumption did you use for your figures?

          Prob(PhD) = sigmoid, centered at 120, capped at 10%, calibrated to result in ~2% of the population getting a PhD (which is the rate for 25-64 year olds in the US)
