HK, do you really think that observed SES differences in IQ and academic achievement are *primarily* due to "gaming the system"?

I am heartened to see that tons of NYT commenters understand The Bell Curve. I will quote just one, named ".N".

There isn't a single mention of the possible (likely) role of IQ differences. IQ is heritable--the extent to which it is heritable is debated, but there's overwhelming agreement that it is largely heritable. IQ is correlated with "life outcomes," a proxy for which is often income.

So, we would expect lower IQ members of the population to be poorer (on average) and to beget children who are (on average) of a similar IQ as the parents. From that perspective, it's completely predictable to have lower income families with children with (on average) worse academic achievement. Throw on top of that a misplacement of priorities, and the disparity isn't all that surprising.
