He says that many people still insist on seeing the human brain as predominantly moulded by culture, despite scientific evidence to the contrary. There tends to be a hesitancy towards attributing any differences between people to any cause that is biological in origin.

I agree with the first paragraph here, but not the second. I really believe that culture plays more of a part than most people think. Cultural differences would explain the higher wages among Asian Americans and Jews, this despite the historic racism that both of those groups have experienced. Both groups are minorities, yet on average still exceed in our society more than others.
