Kind of a shocking choice.
Isn’t this true though? Says more about Harvard than Summers to be honest.

Calling this a truth is pretty silly. There is a lot of evidence that human cognition is highly dependent on environment.
I don't like ignorance being promoted under the cloak of not causing offense. It causes more harm than good. If there's a societal problem, you can't tackle it without knowing the actual cause. Sometimes the issue isn't an actual problem caused an 'ism,' it's just biology, and it's a complete waste of resources trying to change it.
