Interesting link, I just skimmed it but I don't think it quite showed top talent is a myth, but rather that our ways of measuring that talent is flawed, this syncs up with ideas from Moneyball as well. We know that pitching is a talent, but we struggle to project who will be the future star due to our preconcieved biases.

So in the story they found a stronger correlation between tacit knowledge than simply IQ for instance.
