Bravo for responding so clearly and accurately to such a pervasive and wrong belief. The best overview/summary I have read is The Genius in All of Us by David Shenk[1]. It would probably not add much to your understanding, but to anyone who hasn't looked extensively into these ideas, read this book.

Seriously, if you're reading right now, stop what you are doing, and read this book. It will change your understand of what you are capable of.
