What do scientists think about the claims in the Google anti-diversity document?

Google CEO Sundar Pichai (note to employees):

> Our co-workers shouldn’t have to worry that each time they open their mouths to speak in a meeting, they have to prove that they are not like the memo states, being “agreeable” rather than “assertive,” showing a “lower stress tolerance,” or being “neurotic.”

Evolutionary biologist Suzanne Sadedin (quora answer linked here):

> It’s true that women and men, on average, have been found in some studies to differ in empathizing/agreeableness, systematizing, gregariousness versus assertiveness; and neuroticism.
