He's an engineer for Google (with a purported PhD from Harvard - likely to only be a MS) that wrote a 10 page article critiquing his company - specifically - for ignoring the science when making decisions about company culture. From someone with his credentials making these claims I expect 15+ peer reviewed sources with at least 1 review article from each field that studies the topic (sociology, economics, anthropology, psychology, biology).

Someone with his credentials should not expect to be spoon fed justifications for company hiring practices. If he had opened discussion on the validity of specific findings and which experiments contain the most valuable information for predicting benefits of policy changes, I don't think there would have been this outcry.

But if he wants to discuss the science he first needs to make it clear that he's read it.
