I think you have two reversed, if you want to buy into such racist garbage. As for Asians, it depends on the part of Asia. Japanese are believed to have the highest IQ, though newer evidence suggests that is not genetic. In fact, the smart Asian stereotype probably didn't exist prior to WWII. We felt a certain amount of guilt and did war reparations, and not only did we give them factories more modern than our own, we sent some of our best leaders down there to teach them new philosophies. Think of Lee Iacocca of Chrysler and men like that. They went down there and brought their ideas about success. Then the Japanese merged it in with their traditions and spiritual practices, and this was all taught in the schools, and they created a competitive society, and parents were applying tremendous academic pressure.Blacks have the highest iq while Asians have the lowest. The white devil is somewhere in the middle.
You may have noticed that most of the Japanese people from a couple of generations back wore thick eyeglasses. For many years, people assumed it came from Hiroshima and radiation causing genetic mutations. Scientists also once assumed nearsightedness was mostly genetic. Since then, studies have seemed to refute both notions. One thing that is a supposed risk factor for nearsightedness in children is sleeping in the light. If there is a lot of light, the eyes try to focus, even if closed. So all night long, they are tensing their eyes and unconsciously trying to focus on the vessels in their eyelids. Since they are still young, the eyes are still soft and growing and that constant tension causes them to elongate over time, thus creating a need for corrective lenses. Now if that is true, what about constant tension to elongate during the day? So if you are shamed for not knowing certain things, and your self-worth is tied to your IQ, what will you do? Probably nonstop reading, studying, technical endeavors, etc., most of which is done very close. And if this is your entire childhood from maybe age 3 or 4 on, you just might need thick glasses.
So back to IQ, even if you have less genetic predisposition to high IQ, if you are healthy and relatively "normal" and pushed hard enough, long enough, you'd certainly have higher IQ than if nothing were done. A study done in my state years ago proved this, where it took mostly minority toddlers and placed them in a special high intensity "day care" sort of environment. It was a bit like Head Start, but more intense and started even sooner in life. There was also a control group, and both groups got medical exams and care, food assistance if necessary, police and social services attention at home if necessary, etc. In other words, they tried to remove some of the factors related to poverty to be able to test just the program. So they wanted the education intervention evaluated, not any incidental interventions done as part of the study. This program was studied longitudinally and the participants and controls tracked throughout their lives until adulthood. The study group was about half as likely to drop out, get pregnant while in school, use drugs, or break the law, and more likely to finish high school and go to college and graduate. Head Start has not shown the same level of success.
