In more recent discussions, Daniel Shenk’s book “The Genius in All of Us” suggests that we all can be geniuses if we nurture children and have an optimum environment. This is an interesting argument and it’s become understood that environment influences many outcomes including culture, behavior and intelligence. It’s an interesting response to the Bell Curve. One can clearly support the idea that children should be given a positive environment to grow up in. Lead and other toxins can lead to lowered intelligence and learning disorders, and nutrition is very important, lack of certain vitamins can lead to birth defects. I have seen many exceptions to this, people from questionable, and even problematical backgrounds who show brilliance. Why does this happen. I have also seen in this within large families, numbers of people with giftedness in those families. I doubt gifted people grow up in families with normal or sub-normal intelligence like the television show “Family Guy” would suggest. There may be many cases where giftedness is masked by other problems and one may hide their giftedness from others for fear of ostracism and rejection. I suspect that one’s ability can be enhanced by an enriched environment, but the real differences between gifted and non gifted people are unlikely to be the result of environment solely.
In another book by Steven Pinker, “The Blank Slate: The Modern Denial of Human Nature” he reminds us how John Locke’s (1632-1704) idea Tabula Rasa, which suggests we are born a blank slate has permeated social science research and every day beliefs about what contributes to human development and behavior and the world in general. He suggests that we deny human nature. I doubt that we want to see this as an either/or type of situation, but we need to consider how influential Locke’s theory was.
