The question of learning takes a new turn... it's long, but it can change your life.?

Wow, this is some interesting stuff, and to immediately answer your question, it's kind of reassuring to know that the "talented" are within reach of most everyone's capabilities if they truly work for it and put themselves in the right setting since intellectual barriers such as IQ are mainly focused on our social upbringings and environment and don't truly express what intelligence is. It explains how people who have scored considerably low in school and other grading systems while still turning out to be some of the most brilliant people of all time (Charles Darwin and Stanley Kubrick both suddenly come to mind with this). With that in mind (supposing I've got the gist of what you are explaining), are you saying that it is our social confidence and how we believe we fare in relation to the rest of our society that determines our "talent"? If so this leaves me with a few questions that I'm hoping you could clear up: Firstly, if we are all born with the same amount of "talent" and our surroundings then shape our neurological capacities and abilities, wouldn't that mean that all upper class people would be relatively close in terms of their IQ, while everyone in the slums would maintain a poor IQ (which isn't true, brilliant people have risen out of the streets, and failures have emerged from wealthy families) such that there would be a more noticeable trend? And this may be true for our minds, but (since this is located in the tennis section) does this maintain true for the physical aspect of talent and not just the mind (the Williams sisters truly seem to be on another level of athletic ability which we attribute to natural talent)?
