Just to add another variable to consider, studies show* that men and women perform considerably better or worse at stereotypically masculine and feminine tasks depending on how their identity is primed.

Considering individual variance and societal influence, making assumptions about an individual's capabilities based solely on their sex seems foolish and even harmful.

* Sorry to provide this without citation, I believe the studies are cited in the first section of "Delusions of Gender" if anyone is interested in the topic.
