<li><p>There's so much cultural dreck in the SAT and major-choice data that I don't think you can begin to draw conclusions about "innate" abilities from them. And, as others have noted, the terrain seems to be shifting. I know two young women who are math majors at Harvard, and they aren't the only ones; when I went to college, I doubt you could find two women math majors in the Ivy League.</p></li>
<li><p>But to jessiehl: The MIT major choices are random???? Women disproportionately like environmental stuff and earth science; men disproportionately like rockets? That doesn't seem random at all -- that seems like a cliche.</p></li>
<li><p>And what if there ARE innate differences? There could be significant innate differences on a statistical basis, and it would tell you nothing useful about any individual. It might mean that it would be unreasonable to expect that women would eventually constitite half of the tenured physics faculty at MIT or half of the physics Nobellists, but it wouldn't mean that Woman A or Woman B wasn't the greatest physicist of her generation. It is difficult, politically, to have a discussion of the possibility of intelligence-related differences that may be based on race or gender, but even if they exist their meaning is practically nothing. Cornell West and Helen Vendler are still going to be smarter than practically everyone, probably including Larry Summers (who is PLENTY smart).</p></li>
<li><p>My family: My wife and I are not science-oriented at all. She had typical (for our generation) female math anxiety; I just thought math and science were pretty pedestrian compared to literature. </p></li>

<p>In early middle school, my daughter was the best math student in her grade; everything came easily and quickly to her; she was very fluent with concepts and understood their relationships. She was placed in an advanced math track, whereupon one bad teacher just killed her interest in math. Dead. (However, she limped her way through calculus in high school.) Her math SAT was 100 points below her verbal. She chose a college where she would have to take a fair number of math and science classes, but she pretty much hates every minute of them and blows them off. She has wanted to be a writer since she was 10. The single adjective that her friends would use to describe her (and I would agree) is "analytical".</p>
<p>My son (two years younger) has always done well in math and science. He was not initially advanced-tracked, but doubled up on math in 10th grade to catch up. He won the top prize in biochemistry at his school as an 11th grader; he chooses a math/science-heavy curriculum; his math SAT is 50 points higher than his verbal. (He actually said the following a few months ago, something I did not think it was possible ever to hear: "That's my easy exam day. I have math and physics.") We made a conscious decision early on to get support for his science-type interests -- more than his parents could provide -- so we hooked him up with a neighbor who is an academic biophysicist, and helped him get a volunteer position in a paleontology lab (where he has worked for 3 years now, loving it). But. As time goes on (and to the dismay of his science teachers), he is increasingly defining himself as a humanities person. A year ago, his significant extracurricular reading interest was Richard Dawkins; now it is Salman Rushdie. He dropped robotics because he wanted to be an officer of the Drama Club. He won a regional poetry prize, too (shocking everyone, since no one knew he wrote any). While he is still nowhere near as sophisticated a writer as his sister was at this age, all of a sudden he is a fluent and stylish writer.</p>
<p>Anyway, my point is that whatever "innate" abilities people have, they get put through a very complex social/familial wringer and emerge in very complex packages. SAT scores, and even major choices, are essentially snapshots in a long process. They are certainly valid data to describe something that exists, but they don't mean as much as people claim, and don't tell you where people come from or even where they're going.</p>
