Interesting. I disagree, believing that culture drives most of the mentioned traits. The mind is inherently flexible, adaptable in many ways. A Laplander raised in Jamaica by an average Jamaican family would have more traits in your "black race" category than a black man raised in Siberia. A violinist from Venezuela might easily have more in common (from your list) with a violinist from Australia than with Hispanics from Argentina. Culture, taught didactically in school and through observance of social norms, shapes a tremendous part of any group. Individuals add their own gifts and handicaps to the group.
