Women are maybe smarter... so do not spend there whole life studying a 'game'.
But seriously, it is to do with the way the brain is 'wired'. Women are not as good (in general) at tactical/logical pursuits in the context of a game. They also do not often posess the same winning desire. Of course there are many exceptions (Polgars, Xie Jun, Cramling etc) but even these never make it to the real top in the mens arena. I also think many younger girls were/are turned off by 'male dominated' smokey clubs and tournaments. I have been thrashed by a 9 year old girl before though (fairly quickly if i remember). Same with Snooker and Darts, I guess.
Let us hope this will change, I think it is already slowly changing.
Something I don't understand. I understand in arenas like basketball, where men simply have a natural physical advantage. But there is no proof that men and inherently smarter or better thinkers than women. The closest we have to that is that men tend, in general, by a tiny margin to be more analytic thinkers than women. And that is very vague, at best.
The classic response I've heard is that "chess is a sport/game dominated by men". And this is undoubtedly true, we have numbers to show for that. So I understand the logic there, kind of. It is undeniable that, if we assume that the average man and woman chess player are equal in skill, it is more likely that a man will win the world championship, simply because, well, there are more of us. The same could be said about the likelihood of a redhead of left-handed person winning the championship, at least going by simple probabilities.
But patterns and probabilities in the general do not determine what a person will do, it simply says what is likely. An example of this is that teenagers have way higher insurance rates for driving. That doesn't mean a teenager is a more dangerous driver, it just means that on average, they're more likely to be. If you need further proof, look at our President elect, a black man who won a completely white dominated political seat. Look at Yao Ming, a top player in the NBA, a sport with very few Chinese people. Look at Tiger Woods, who dominates perhaps the "whitest" sport in the world (next to hockey, maybe). My point is that simple probabilities say that none of these people (statistical outliers) should be where they are, and yet they are.
But we don't close sports to race, thank god. Why to genders? Is there something I'm missing?
