Record Set For World's Youngest Chess Champion

Pickens writes "Hou Yifan, a 16-year-old chess player from China, became the youngest world chess champion on Friday, in the final of the Women's World Chess Championship held in Antakya, Turkey, toppling a record held since 1978. Currently, the top-ranked woman is Judit Polgar of Hungary, who is thought to be the best female player in history but Polgar, once ranked No. 8 in the world among all players, men and women combined, does not compete in women's tournaments and did not play. No one really knows why the best female players are typically not as good at chess as the best men. One theory, common among some top male players, is that men are usually more aggressive by nature than women, and are therefore better suited to a game that simulates warfare. Another, cited in at least one university study, is that the talent pool among women has not been big enough to produce many great players."

Not surprising

[NoSig]

Chess requires high IQ, the variance (not average) of IQ (and lots of things) is higher among men than women so you get more male idiots and geniuses. In other words, more men are further away from the average than women - be that better or worse. Hence better top performers in many areas of human activity. Also, more male bottom performers. It's not exactly surprising that women have less variance since they have two different X chromosomes, so the effect of every gene on the X chromosome is the average of two genes from the gene pool, while in men the effect of every gene on the X or Y chromosome is just the effect of 1 gene. So a good X or Y gene gets full effect in a man and a bad X or Y gene gets full effect in a man. In a woman the X genes have two copies so both bad and good genes are likely to be counteracted by the second copy of that gene on the other chromosome. Women don't have a Y chromosome which also means they can't differ in their Y chromosome, again reducing variance.
