From the memo:
"I’m simply stating that the distribution of preferences and abilities of men and women differ in part due to biological causes and that these differences may explain why we don’t see equal representation of women in tech and leadership"
preferences and abilities he says.
He suggests ways to alter Google's engineering jobs to suit abilities females are more likely to excel at, such as making work more social.
Its almost like different doesn't mean worse.
oh and diversity programs are bad. for some reason.
