The memo suffered from a lack of 2nd order thinking. If Google really is using its diversity programs to "lower the bar", that's what should have been proven and addressed, whether men and women have innate differences in talent for certain occupations is irrelevant. It's Google's perogative/obligation to find and retain the best talent. I suspect that's what the purpose of their diversity programs are for. If they're not, and they are truly attempting to "lower the bar" for ideological reasons, then by all means call them on it, but the labor market will punish them for you. The whole memo was an irrelevant red herring to the topic of Google's hiring practices.
