I'm talking about the sentence I specifically quoted in my OP, which states that all individuals are born with approximately equal potential for intelligence. I don't believe that to be the case. I believe genetics provide varying levels of potential across the human population. Admittedly, this is based largely on my experience as a highly intelligent individual from a family that displays far above average intelligence in general, which is why I am seeking out science that speaks to this. I don't like relying on my own anecdotes. My reading from links gathered in this conversation seems to back my intuitive position thus far, but I'm always willing to re-examine my ideas based on evidence, so if you have something to throw at me, please do!
