Intuitive reasoning... we don't care about sample size and bias--at least not immediately, right? All we care about is the case study on Usain Bolt.

Who is a product of an intense selection process that includes every track and field team in the entire world. My high school had less than 300 students and it sent boys to run the 100M. None of them went to the Olympics.

Sure. And why do you think that it's not because the ones who made to the Olympics don't have de novo mutations, rather than germline transmitted loci?

Because then maybe a Euro or Malay or Patagonian would have an Olympic gold medal for sprinting right now. West Africans tending to mutate into sprinters is not a parsimonious explanation.

The greatest sprinter in the world, Bolt, comes from dead in the center of tons of other great sprinters. Similarly, the greatest marathoner, Kipchoge, is from dead in the center of the peak Kenyan district for distance running talent.

Not sure if this is true or not. But assuming it's true, you obviously can see how this can be a cultural confounder.

It's almost as if to be the greatest of all time, you need both Nature and Nurture working together. E.g., Michael Jordan is very black and he grew up in North Carolina, one of the 4 most basketball crazed states (with Kentucky, Indiana, and Kansas).

I do wonder when Francis Collins said "it" is "primarily" due environmental he meant 51% or like 95%.

My default is to begin by assuming that the likeliest answer to a Nature - Nurture question is 50%-50%.

it IS a common temptation for new right bro-science theorycrafters to assume the total opposite of conventional wisdom - thus the bloggers claiming fathers have 0 effect on outcomes, but just happen to have genes that correlate to staying with kids. We should follow the facts.

That particular claim is absurd - if it were the case the actual sticking around is a massive cost for zero benefit - evolution would quickly dispose of such wasteful behavior.
