Damore said higher proportion of men in engineering positions wasn't because of explicit discrimination. And we know Google fired him afterwards stating he was wrong. But All 25 Finalists In Its Code Jam Coding Competition are Men. In fact, With the exception of 2011, in 14 years of Code Jam, no Female has ever made it to the finals. Google's own non-discriminatory machine tool that evaluates codes, which doesn't tak…
How? Assume for the sake of argument that discrimination is the only factor influencing the gender distribution among CS professionals. From kindergarten onwards the numbers are slowly winnowed down to 80% men and 20% women.
But now this 80/20 population enters a highly selective but objective contest and comes out with 349/1 (assuming there have always been 25 finalists in the 14 years of the competition and there was only this one woman I can't see in the photo proof). Surely this means that men are just better at programming?
But in fact men are just better at being outliers. The effect is not very strong at small deviations (i.e. the difference between an average person and an average programmer), but can absolutely become significant when you only look at the extreme ends of the distribution. (I have written a comment about that here https://news.ycombinator.com/item?id=14997524) When you only look at the 25 top performers, that is bound to influence the result.
Again, I don't think things are nearly so black-and-white, but pointing at one extreme case of men performing better wouldn't be enough to completely validate Damore's memo, if anyone were so stupid to make that argument.
