Truth is that many Anglo Americans and Latinos are to the left on the curve to the Asians. One doesn't hear Anglos and Latinos complaining.
You will if you go to a few "race realist" websites. There's a number of whites who refuse to believe that anybody could be smarter than they are. They think Asians cheat on tests or study harder. (Of course, Asians do study very hard, but that's part of having a high IQ). Nothing to do with superior intelligence as far as they, the "race realists" believe. Which proves a number of whites are unwilling to accept reality as well as many blacks and other minorities.
My own view is IQ is an excellent determinant of future success. If you can find me numerous SV employees (or physicists, nuclear biologists, mathematicians) with average or low IQs, then I'll believe otherwise.
