Late exposure to higher mathematics sounds perfectly plausible. Someone getting into sports at 15 is rarely going to compete with those that started at 10, assuming equal innate talent. The same principle applies to academics. Would be nice to see some envelope math on the respective importance of IQ and socioeconomic background/nepotism in academia (many PhDs have parents with PhDs etc).
