On average, there is a 15 IQ points gap between whites and blacks. Is there a scientific consensus on whether this gap is explained by nature/genetics, nurture/environment, or both?
This NYT article refers to a quote from Dr Francis Collins saying that most experts on intelligence “consider any black-white differences in I.Q. testing to arise primarily from environmental, not genetic, differences.”

Is that true, or is he being politically correct?
The article also mentions James Watson's unchanged views that the gap is explained mostly by genetics. It refers to his infamous comment on black people's intelligence being the same as whites: “people who have to deal with black employees find this not true.”
After looking at the bell curves, I am afraid I would never look at a black/african person the same again. I never thought that science would teach me to be racist.
Edit: My thread may share the same 'topic' with others, but it is not a duplicate. I am asking more specific questions with regards to the scientific consensus on the matter, and whether Dr Collins statement in the NYT article is true.
