About Half of Kids' Learning Ability Is In Their DNA
Taco Cowboy writes with this story about new research that finds a strong genetic component to a child's ability in math and reading. "You may think you're better at reading than you are at math (or vice versa), but new research suggests you're probably equally good (or bad) at both. The reason: The genes that determine a person's ability to tackle one subject influence their aptitude at the other, accounting for about half of a person's overall ability. The study, published Tuesday in the journal Nature Communications, used nearly 1,500 pairs of 12-year-old twins to tease apart the effects of genetic inheritance and environmental variables on math and reading ability. The researchers administered a set of math and verbal tests to the children and then compared the performance of different sets of twins. They found that the twins' scores — no matter if they were high or low — were twice as similar among pairs of identical twins as among pairs of fraternal twins. The results indicated that approximately half of the children's math and reading ability stemmed from their genetic makeup.
A complementary analysis of unrelated kids corroborated this conclusion — strangers with equivalent academic abilities shared genetic similarities. What's more, the genes responsible for math and reading ability appear to be numerous and interconnected, not specifically targeted toward one set of skills. These so-called 'generalist genes' act in concert to determine a child's aptitude across multiple disciplines. The finding that one's propensities for math and reading go hand in hand may come as a surprise to many, but it shouldn't. People often feel that they possess skills in only one area simply because they perform slightly worse in the other."

and these are unequally distributed in different races
I've got a kid who is clearly ahead of the class with mathematics but clearly behind the class with reading. So, these studies probably mean it isn't a fundamental ability problem, so where do I go from here?
Aptitude is only half the story. The other half is being interested in the subject.
Well, possibly, but experience teaches that flat-out racism is a more likely culprit. We've seen people of all races and ethnic background perform at a very high level at every possible field, including Jewish and Italian basketball players and African-American pure mathematicians. What Murray (and you) are always looking for is the ceiling and floor. That's racist.
Plus, we've learned that there is one additional defining characteristic of racists: They will go to great lengths to try to rationalize their bigotry. And that, was my point. You've confirmed that.
You are welcome on my lawn.
