It is widely understood and accepted that males and females differ in their physiology in ways that have dramatic impacts on their capabilities. However, the two groups form overlapping bell curves, and if you're seeking someone for a task you'd be a lot better off focusing on the attributes of the individual, which may be at either end of their group bell curve or anywhere in between.
Put differently, my wife, when she was a serious triathlete, would never have been able to beat the best males at any distance. But she could beat most of the males in a half ironman. So if you were interviewing her and some male to do something like a half ironman, you'd better make sure you ask a lot more than "what sex are they?". You'd better find out if the male is in the top X%, because if not, you should be hiring her instead.
All of that is true despite the group differences being real and significant.
Hiring is never about groups ... unless you're a racist/sexist/*ist ...
Frankly this just reads like a cover story for "I don't want to have to care about this".
So now...what? You've won, because I've "outed" myself as "racist"? Sorry to have to break the bad news to you, but there are very few intelligent people who still believe that there are no genetic group differences. The intelligent people who hold onto the blank-slate and group-egalitarian ideas either haven't given it enough thought or just choose beliefs that don't make them uncomfortable.
