One problem with Murray’s graph is that Hispanics are a “polyglot” of races. Another is that all the racial groupings are somewhat arbitrary as to who actually fits in each classification. Finally, you can’t use such a generalized graph to imply the IQ of any specific individual.
Valid points, but our government has bought into the idea that blacks and Hispanics (however defined - and it does change!), and even women, are genetically inferior to white/Asian men and not only must be held to lower standards, but must also be hired just to give them the appearance of productivity and assimilation.
I think it's meant to imply urban dwelling Central and South American people currently living and working in the United States. Somebody said "lets say Hispanic because everyone will know what we mean anyway"
That is why it is a normal distribution with mean median mode at the center.

So is "white." Poles have a different (higher) IQ spread than some other European (nations, tribes, whichever you prefer) distributions of IQ. Murray's (and others) research highlight and reveal trend data that is reliable statistically (produces similar results under consistent conditions).
