hmm! my respect for Harvard grad students just went done a notch!
One commenter asks if I had the same experience with my own students. My students are not precisely representative, but it’s worth noting that they’re not immune. I once had a Harvard grad student call me at 10pm the night before the exam (not sure how she got my mobile number) to berate me for discussing something called the “Cold War” in class as if everyone was supposed to know what it was about. She said she hoped it wasn’t testable.
