On any task more complicated than sheer physical strength, there is no such thing as inborn talent or practice effects. Any non-retarded human could easily do as well as the top performers in every field, from golf to violin to theoretical physics. All supposed "talent differential" is unconscious social signaling of one's proper social status, linked to self-esteem.

A young child sees how much respect a great violinist gets, knows she's not entitled to as much respect as that violinist, and so does badly at violin to signal cooperation with the social structure. After practicing for many years, she thinks she's signaled enough dedication to earn some more respect, and so plays the violin better.

"Child prodigies" are autistic types who don't understand the unspoken rules of society and so naively use their full powers right away. They end out as social outcasts not by coincidence but as unconscious social punishment for this defection.
