I was a TA at Princeton ~5 years ago, and I had forgotten about the honor code until reading this. Yes it's true, we did not proctor exams, and students seemed to take pride in it. On every test, you got the names/signatures of those sitting next to you. But also, I had a student who was accused of not putting his pencil down when the test had concluded, and the bureaucratic process to fight the accusation was so crippling that they had to take a semester of leave anyway. So I don't see harm in tearing it down.
"Prefer women" could be in a sexual context, romantic context, platonic, etc. and the commenter above didn't define it. I imagine it's hard enough for bisexual people to be asked if they're "living a lie" by having to choose a side.
Just to be clear, we don't actually know what that does right? Like, there's no link to this making up for poor sleep or improving your cognitive function right?
