I didn't give any definition to talent, I just said that it is related, very closely, to luck so I don't see how you can oppose them to each other.
I see it similar to asking "what is more important for a fruit - the peel or the meat?" while you can't have one without another, both are there together making a fruit what it is :)
That doesn't answer either of my questions. Sorry I was unclear about "your defintion" - it was implicit and allowed for folding in all the "luck" aspects you are including.
I see why you are saying the factors are somewhat confounded, but that does not implicitly mean that separable analysis is not possible or useful. I don't think your analogy holds and these are nearly as coupled concepts as parts of a fruit.
