On a related note, was watching Olympics yesterday. It was a shooting day, and I was kind of surprised that men and women competed separately. I understand separation in physically demanding sports like weightlifting, but pistol and rifle shooting have no such requirements. And historically war snipers were a mix of men and women.

Fun fact: Shooting was only segregated by sex after 1992 - when a woman won gold.

For those who want to fact check. It was not the whole Shooting category but only Skeet. https://en.wikipedia.org/wiki/Shooting_at_the_1992_Summer_Ol...

> It was the last Olympic skeet competition open to both men and women, and the only mixed shooting competition at the Olympics ever won by a woman: Zhang Shan.

Particularly interesting, as Skeet is, if anything, more physically challenging.

I was thinking about it, like why there are separate competitions in chess or cybersport or like you said shooting. Can't say for sure, but probably it is because tournament is a tip of the iceberg of what contenders are actually competing in.

For non physically demanding sports most of the work is in training prior to this competition: being able to find good coach, stick to regime, balance life vs sport, emotional control, managing finances and sponsorships, chances of getting into the sport in the first place etc. These aspects are quite different for men and women, so they naturally have separated tournaments.

As far as I know about chess, there are no men-only tournaments in chess. Instead everyone, both men and women, can compete in the "usual" tournaments. But because there are so few female chess players around, to encourage girls and women to play chess women-only competitions were introduced. Some think that such women-only tournaments work as intended by promoting chess among females, some don't. Famously arguably the strongest female chess player in history Judit Polgár never competed in the women's world championship.

IMHO it should be the same in sports. This would also make it easier conceptually to prevent trans women from competing with other women iff they have an unfair advantage, as the other category woul not be marked as men only.

Twice as many events and medals for competitors, assuming you don't buy into the idea that men have their own competitions so they don't have to lose to women (see also: ski jumping).

They compete separately in Chess as well.

Chess is special case. Women are allowed to play in men torunaments. Not reverse. There are even special rules (since 1976) which specifically says that women cannot be prevented from participating based on gender (it wasn't clear to Indians at this time). Some (Judit Polgár,Vera Menchik) almost never played in woman ones. Chess rating system didn't take take gender into account but in 1986 active woman chess players excpt Susan Polgár got small bonus to rating.

There is research from 2007 ( https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejsp.440 ) which shows that if is via Internet and women thinks their opponent are men - they show worse results. If gender is not known to both sides - results are mostly same.

It's not currently clear if M2F transgenders should be allowed to play in women competitions.

This is one of the weirdest for me, because there's literally no barrier that can justify this separation. And GMs like Hou Yifan for example can go toe to toe with anyone now.

In theory there's no reason. Yet aside from Yifan and Polgar there is no women GM which could go toe to toe with the top male GMs. The same is true historically.

It is unclear why, this requires further research - the Chess world decided to just roll with it and have separate tournaments.

You can't just make stuff up. Hou Yifan says herself that chess is very exhausting and men have an advantage in this aspect.

"I think there is a physical aspect because chess exhausts a lot of energy, especially when games last 6-7 hours, and here women could be more disadvantaged."

Why deny differences in biology to further a false reality?

You mean the same Hou Yifan who said multiple times that she was speculating?

I'd trust the world champion of chess to not mention physicality as a possible reason unless it had merit. She's been playing chess her whole life.

I'm not disagreeing with her opinion or negating her experiences, it's not my place. That said, classical (3h+) isn't the only form of chess, and it could be something that is personal to her and not representative of female players as a monolith.

Logically speaking, it's still a disadvantage even if it's one that matters less in some scenarios. Gender is highly predictive of a lot of biological statistics. Truly, we should be basing brackets on the biological stats themselves and make gender segregation a thing of the past. How will people react when the brackets reflect genetic potential rather than gender potential? Probably just as oppositional. People hate being told that someone else has a higher potential than them even if it's true. I don't blame them. But we can't live in a reality where we pretend that some aren't better built for certain endeavors.
