I think there are real differences in the way our minds work. The celerity, aggression, and objectivity as mental skills associated with blackjack AP are statistically more common in men than women. But if an individual female has those skills those statistics don't apply to her, so she has nothing to worry about. She may be a freak, but so are male AP's. Every one of us is abnormal in some way. The Chess vs. Go paradox- the top-rated female chess players in the world would be mediocre players among men. Despite being non-physical, there are separate competitions for men and women. The game of go is at least as demanding and many would say more so, but men and women are equal as go players. Even more astoundingly, go is played mostly by Asians where there are still a lot of traditional social barriers which restrain females. What the heck is going on here? The mental skills for chess are completely non-transferable to go, so understanding why this is would explain a lot.
