This was a worthwhile discussion. However, I am disappointed that Mr. Haier failed to present the actual genes associated with IQ, especially because it's his main assertion. Furthermore, I believe he contradicted himself multiple times in this conversation: For a prime example, by his own admission, IQs go up as a cohort, which means environment and nurture also play important roles in intelligence. Furthermore, he fails to acknowledge how oppression creates mal cultural practices or how it prevents others from achieving in society. Furthermore, oppression creates trauma in the brains of oppressed people, which would certainly effect cognition. He also admits that nutrition and other factors, like lead, can effect biological development, and thus, intellectual capacity. These points only scratch the surface of points he hasn't considered. I'm disappointed in his failure to apply the scientific method by only considering the data that confirms his presuppositions.
