I'll sleep on this question. I have an early show tomorrow.
It is an interesting question but as VariablePitchP has said, there is a big disparaty between the numbers of female pilots to male pilots. That's not changing any time soon.
Are women less likely to do a rash action in the flight deck? Maybe? But no one knows at this point in time. There's just not enough of us to do a valid comparison.
About the only event I can think of is the QF B744 Bangkok golf course redesign versus the QF B743 captained by a woman who decided to go around during the approach before the ill fated QF B744. Naturally, there's a lot more to it than sex differences between the captains.
Personally, I'd say there's more cultural/fleet culture/background/experience that influences behaviour at this level than sex.
