It's a valid question, but Singer gets the answer wrong.<p>This is politics, not science.<p>1) Biology is a red herring. There's a huge chasm between any supposed biological difference, and an actual model that can predict what proportion of employees should 'naturally' be male or female.<p>Then there are culture issues (which are likely much larger than any biological ones, after all countries like India have roughly 50/50 representation without needing special intervention).<p>Then there are bias issues.<p>To leap all the way from some small (debated) physiological differences to suggested HR policy in a single bound speaks more to politics than science.<p>This requires primary research, not memos and hyperlinks.<p>2) Damore takes his selection of gender research and then generalises to <i>all</i> forms of diversity... even accusing diversity programs of "lowering the bar", which is incorrect and damaging to his colleagues hired through those programs.
