Sorry I don't have a citation for that. As far as I know it hasn't been researched. I was mostly being flippant but I'm not ready to let go of the concept of Talent. There are people who are no more knowledgeable or experienced than I who are way better than me at stuff.

Being able to spend that much time in that focused of an effort seems like a talent or perhaps a "condition" like Asperger's.
