This, like the Bell Curve, ignores the environmental impact on career choice. I scored in the 98th percentile on science achievement tests. No one encouraged me to pursue medical research. It was unheard of because of my race and gender. Never tested, they said I had average or below average intelligence. At the age of 47 years,  I scored as intellectually superior on one test and higher than 705 of the population on the other. These scores were met with displeasure by my career counselor. Empowered I finished my B.S. degree, pursued a career in technical communication. Exclusionary and abusive environments limit academic and career choice.  Blacks pursue careers in sports not because their brains and bodies are hardwired to excel there, but because they are exposed to it in their environment and it is where they see people that look like them succeed.  My premise: women exposed to exclusionary and abusive environments cause changes in the areas of the brain that impact career choice.
