A hierarchical pyramid with a few tenure / dean positions at the top will do that, just as it does in corporations.
Is "Dissuading people from publishing takedowns of my paper" any different than "Switching KPIs post-hoc" after an executive's pet project failed to deliver the expected results?
My point being: Scholarship isn't why anyone becomes president of Harvard. It isn't why anyone becomes a dean at Harvard. It probably isn't even why anyone gets tenure at Harvard.
That's base level academic competency + politics.
So accusing Claudine Gay of 'getting her position for reasons other than scholarship' is... yes, that's why everyone who's ever sat in that seat got it.
diversity isn’t an inherently dirty word. it can be used as one, sure, but it doesn’t have to be.
