The main one is that they took fewer kids from good high schools and more kids from bad ones. What makes a high school good or bad? The attitudes and abilities of the students, which are strongly correlated with the wealth of their parents. These also fall generally along racial lines, but then America sets income opportunities, from above and below, largely along racial lines.

So I have a serious question for you (this comes on the heels of me doing a deep dive on PISA testing results, and it honestly has been weighing heavily on my mind lately).
I 100% believe that socioeconomic factors are probably the single biggest factor in academic success.
Is there any possibility that average population-wide genetics play a role in academic success? (I very much do NOT want to use the word "race" because I think it's basically meaningless). Is it possible that, on average, Americans with a large Far East Asian genetic component perform academically better than, on average, American students with primarily Western European backgrounds? What about those with large sub-Saharan African genetic components? Etc.
The question really is--is it _possible_?
My answer is that yes, I think it's possible. I don't think academic achievement is the most important thing out there, but it's important.
And, if it's possible? What the heck do we, in a free and democratic society do about it?
It's bleak and dystopian to think about!
