Even more astounding is the reporting number.

If 44.6% of students saw an honor code violation and didn't report it, and 0.4% of students saw an honor code violation and did report it, that means that 99.2% of Princeton students that pledge to report honor code violations break that pledge. And that's only counting the voluntary reporters, meaning that the actual rate is presumably even worse!

But also, how would reporting a suspected honor code violation even work? There's intentionally no staff witnessing the exam, and you aren't likely to know the names and faces of your whole class, so what would the professor even do with that information? "Professor, I saw someone take his phone out, I think maybe he was cheating, I don't know his name." Okay, thanks Captain Non-Actionable. We'll file that in the circular academic integrity investigation bin.
