It's long been determined that lack of stimulation and neglect in infancy/childhood can produce a mentally-deficient individual. I think there may be things we can yet do in developing children that can more closely approach the genetic limits of their potential intelligence.

This is a good point. There is no reason we couldn't maximize the intelligence of people who aren't operating at their full potential, and there probably is some therapy that could help with this. It isn't like there is an over-abundance of super-intelligent people in the world. :-)
