I didn't mean that it was because of gender or skin colour. What I meant, really, is that we select the people who get power in some way. And then we complain that people in positions of power are like that.

My point was that there are probably a lot of "white old males" that just do not apply for positions of power, because they have learned all their life that they don't have the profile we usually select. And those may actually have qualities (like humility) that would make them better in those positions.

Now, it's difficult to say "this time, we will try to select a white old male who has humility, but first we have to convince him to apply even though he has learned his all career that it's not worth applying". But saying "let's try to hire a woman instead" may be a proxy to that. Sure, some women can be exactly like those people we already select (maybe Margaret Thatcher had a profile of the typical "old white male" that usually got into a position of power).

But I do believe that most women or people from minorities have a profile different from the typical "old white males" who are selected. So it may be a good proxy for "trying a different profile". The idea being that by trying a different profile, we may realise that it actually makes better leaders, and eventually the white old males who do have humility may get selected as well.

Not sure if I'm being clear? :-)
