Here is a quick-n-easy example

Am I reading the linked example correctly, that Asian-Americans' IQ keeps growing during the last decade, and everyone else's IQ in USA keeps dropping?

I mean, if you assume that the differences is SAT scores between races reflect their differences in IQ, it seems reasonable to assume that the differences in SAT scores between now and ten years ago reflect the differences in IQ between now and ten years ago. (Either that, or SAT also reflects something else beyond IQ.)

Several things here.

First, look at the magnitudes. The difference between Asians and blacks is about 380 points in 2015. Compared to that number the declines (-6 to -28) are very minor.

Second, while I don't have data at hand, I strongly suspect that the Asian population of SAT takers changed during the last decade. In particular, the upper class of China got wealthy enough and "international" enough to start sending their kids to US universities (which usually involves taking the SAT) and that's besides increased immigration from China in general...
