Polgar treated his theory as a controlled experiment by raising three daughters under identical conditions — and all three became elite chess players. One became the only woman ever to rank in the global top 10, another won the women's world championship, and the youngest became the first female grandmaster in history. The sample size of three, all successful in the same domain, makes this one of the strongest natural experiments in nurture-over-nature.
