In the context of a discussion about chess, they are.

I've played chess since I was young, have taught many people to play chess, have played in company tournaments, play whoever I can when I travel, and there's just no question that the vast, overwhelming majority of women don't enjoy playing chess.

I can't even speak to a possible difference in gender capability because I've never known a single woman who enjoyed it enough to do anything more than learn how the pieces move.

In Sweden, a mere 3% of adult chess club players are women. Women and men then evidently feel quite differently about playing chess (I don't have an explanation.)

Although gender is a political correctness nuclear landmine, imagine if chess had aptitude diversity rules. "No, you can't castle if your Elo is 800+."

My impression is contract bridge has somewhat gender parity in terms of who plays it. [0] The ranking of contract bridge players doesn't appear to measure current quantitative strength, which seems to encourage volume of play rather than skill.

In the context of a discussion about how chess players (and people in general) are treated, however, they are not.

It would be, but that isn't this particular discussion, this is about chess. And so for all intents and purposes men and women are equal.

This discussion is about tournaments, which are about a lot more than what happens over the board.

Is there any evidence to think that? Are there games similar to chess that are dominated by women at the top levels? Is there some reason to think that chess-ability genes are evenly distributed by gender?

My own intuition is that, just like there are more men above 130 IQ and below 70, there are probably more great male chess players than female. This is just the idea of greater male variability which is found across a number of different measures - everything from variation in height to things like polydactyly being more common in men.

> The title of Grandmaster, along with the lesser FIDE titles of International Master (IM), FIDE Master (FM), and Candidate Master (CM), is open to all players regardless of gender. The great majority of grandmasters are men, but 40 women have been awarded the GM title as of 2022, out of a total of about 2000 grandmasters. Since about the year 2000, most of the top 10 women have held the GM title. There is also a Woman Grandmaster title with lower requirements awarded only to women.

Seems like yes.. but also no.

Only when it comes to some biological factors. Most of what we believe separates men from women is learned behavior.

> Most of what we believe separates men from women is learned behavior.

I haven't seen convincing evidence to support this.

There's the possibility that the differences we see in the higher echelons of chess arise from biological differences between men and women. But that possibility is not being explored for political/social reasons.

Ultimately we are all products of evolution. While some aspects of our nature are instinctive (no external sensorial input is needed to exhibit certain hebaviour), others we learn from observing the surrounding (external sensorial input). If you say all behavior is ultimatelly biological, well, of course you are right, but you are not considering what could have been observed learned behavior on the way.

The point of segregating physical sports is to give women (people who went through female puberty) a fighting chance.

There’s a famous experiment by the Williams sisters, two of the best female tennis players ever, who got demolished by a guy ranked 203rd in the world. There is no way for a woman to make up the testosterone difference in sports where physical prowess matters.

No that doesn’t mean every man is fitter than every woman. It matters in top ranks of a sport.

But chess is not a sport. Think about it, how many calories do I burn sitting in a chair and moving my hands occasionally?!

And no, the brain consumes mostly sugars.

Interestingly, grandmasters burn ridiculous energy during tournaments.

Hm, interesting. But doing sports do all kind of things to muscles. And physiology wise men have more muscles. But intelligence is the same for men and women.

EDIT: They don't cite any papers though

That still counts in practice. We can't immediately rewind time and redo things, even if we wanted to.
