Why is this game so male-dominated?

I mean I would prefer to blame biological reasons that to try to convice other people that I'm just not able to put more effort on doing it.

But if you argue that women don't put enough effort while men do, then you came back to adduce biological reasons

Not sure about "an excuse which impute," but it sounds like you don't buy the "women don't try hard" theory.  

Though of course I most Certainly can Not speak for other women, I will gladly testify to this statement in any court in the world:  Although I Very much Enjoy playing chess, I do NOT "try hard" to improve my skills in chess.  Never have, probably never will. (***See myking's colorful description of the game, wherein he makes good use of the word "flaming.")

I think the ratio of male to female players is slowly declining. This seems particually true in scholastic chess. Many other areas are also male dominated (example no female presidents in United States,few c.e.o. of major companies) but as these things change i think chess will change as well.

What did Orwell call that situation? An unperson? Did you or I miss something?

I can tell you that atleast a week and a half of each month, my wife wouldn't be on top of her game if she played. It seems it could be difficult to pursue an undertaking in which 1/3 of the time you can't concentrate, due to headache, cramps, bloating, etc...

Those can be controlled by men, by not drinking. Men don't have the feeling their guts are getting raked out, because they aren't...

While saying that I think there are extremes in both sexes, in terms of ability, I would tend to agree that men are hard wired for extreme measures in every respect. After all, it has been traditionally men who have subjected themselves to the harshest circumstances to provide for and protect our women and children that we shelter and cherish.

Ask any man who has ever been in a war, what it is like when you have no choice, but to concentrate continually for days and nights at a time. When you are weary, hungry, tired, injured and have no comfort from the ills of nature. Yet, men have a particular resolve that is quit astounding to think about at times. Their emotions are supressed until they are robotic. This is one key difference I see between men and women that certainly could account for some of the difference. Most women I have ever known are very catering to how they feel and certainly wouldn't subject themselves to what it would require to be a WCC...

Women tend to play emotionally and therefore play hyper aggressive when feeling confident and hyper defensive when feeling down. They also are less interested in chess than men. Moreover, their brains are traditionally not as good as men in the logical, mathematical, and creative aspects. Finally, they are often less motivated. 

I think there are many factors that contribute to the difference...to say it is all one or the other is wrong...

Amazing how all these people who are anything but great at chess themselves, are always going on with there silly theories, about why women are so bad at it.

It is amazing how some people keep generalizing in a pist poor attempt to prove others wrong or stir up crap...and yet, still are no more accurate...

myking: It's not like people are arguing that men are better people, except perhaps mendez.

To say that men in FIDE have a higher median rating says just that: that they have a higher median rating. It does not have to mean much else -- that men are superior, or that they have some inherent capacity for chess. Even when it comes to chess as I have said FIDE only takes into account a certain portion of tournament chess players. And indeed, a high chess rating is not a thing a lot of people have an ambition for -- certainly it's something you'd really have to want if you were going to put time into it. A man's greater tendency to concentrate on one thing and exclude others, if it's true, is obviously a double edged sword.

Again, myking finds a cogent way to make the salient point here:

Men are capable of focusing on one useless activity to the exclusion of everything that matters, something that women are not renowned for. If i left anything out, sorry! it's been a long day.

I share his pain.  What IS it that keeps driving Some of us to Keep "checking in" here?  Well, perhaps, we're being driven "mad" !-- Yes! "Mad!" I tell you! -- by the topic itself! (!)  How about we try another one:  Why is the game of "Life" so female-dominated? ... hmmm? !

It really comes down to a matter of priorities more than ability, IMO.  And in general the priorities of men and women are culturally different in so many ways that it is difficult to overcome all of that for the sake of one endeavor alone.

And just about anything that is a strength, asset or virtue in one context is a liability in another.  

Without any intended argument ensuing afterward, why do women complain that men try or do dominate everything in life? That was a rhetorical question...

I don't live life like it is a game to be played and won, therefore I am never defeated. This also let's me know my wife loves me for sure... lol

Omg, 2 wise male voices weighing in --- 2 in a row!  My faith is internet-chess-playing-guys is hereby Restored!  (Seriously, thanks, guys!  !)

Hi, Pelikan, I was about to start washing the blackboard but then I saw that you qualified your original assertion, which was far wider than "based on.... one member (or a small subset) of that group".

I live in Olympic Newham here in East London, home to people from all sorts of ethnic and national backgrounds (perhaps the most varied borough in the whole of the UK). I have noticed differences between different ethnicities and backgrounds - certain cultures tend not to marry when first living together; others are married yet don't live together; certain cultures are attracted to certain foods; certain cultures here urinate in public.

This is not to say (for example) "all White British people always do XYZ" - but we must be careful of pretending that differences do not exist.

I've lived in several places with all sorts of ethnic and national backgrounds. In my experience stereotypes are often a simple means to attempt to justify bias towards a group of people, or the prequel to it.

My bad.  Maybe I came into the discussion at the wrong time.
