I've worked with/for brilliant female scientists and engineers before. I personally believe that what makes a good scientist or engineer is a profound insatiable curiosity, and a drive to understand. I've seen this in both females and males.
My point was, when you encourage this, and you help the person understand and adapt to challenges they may face, society is often better off, as we have added to our scientific and engineering pool of talent. If you discourage this by saying "your brain is different", or "you are more interested in feelings than quantitative science", we wind up with a discouraging environment for 1/2 of our prospective scientists and engineers.
I don't see how the latter is a good thing. Damore had a right to author his text. I'd argue that sending it out to others in his company was a bad idea ... generally one should separate personal politics from corporate life. But I disagree with numerous things in the text (I read it when it came out).
The difference in chromosomes trigger all sorts changes in the development cycle of humans. Unless you want to argue that males having 10x the testosterone levels has no effect on behaviour. Not to mention all sorts of differences in brain structures.
Which is how I interpreted what Damore was trying to do with his memo: saying that women are capable, but that the environment was not appealing to them. Either/both of (a) what they got to work on, and/or (b) how they were treated.
IMHO, men and women perceive and react to the world differently, and treating them the same is foolish and counter-productive. Damore was simply pointing out those differences.
I found The Female Brain a good book on this topic:
