Princeton is a strange place. What on earth could be the objection to proctoring? I'd much rather have a proctor than have to narc on a classmate. And even then, the proctor just reports the matter to a student-run body? Wild.
Right, but there’s really only two directions you can go.
1. Install a culture of honour/virtue/accountability. Rely on duty and moral justice to keep the majority in-line.
2. An arms race to prevent ever more sophisticated methods of cheating, and the reduction in human dignity this implies. (E.g. the proctor must follow you into the toilet).
We all want the systems to be fair and just; but we also all want to be treated with dignity. No easy answers.
Stanford has this policy too. Students get livid when proctoring is proposed, even though cheating is rampant (afaict)
As someone who has attended this kind of program, it's because some students will cheat and view proctoring as an annoyance.
Imo it's both on the students (plenty of students are optimizing just to get a class out of the way to do more interesting stuff) and the programs (some classes just aren't up-to-date or are rightfully viewed as busywork).
Personally, I found courses that were output heavy and regurgitation light tended to be the most successful from an honor code perspective - you can't cheat your way out of "learning by doing" when you are held accountable for the output (eg. A research grade paper or implementing a fully functional Linux kernel).
Sadly, even at Ivies most lower div classes are just rote memorization because class sizes would be massive for plenty of core classes (100-500 students for some classes).
Some schools love to pride themselves on their students' integrity. They don't proctor because they think their students don't cheat and can be trusted. I don't know about Princeton but a college my family attended had stats showing no difference between test scores in proctored vs. unproctored exams. That was before LLMs would have made it so easy to cheat. Maybe that school has changed its policy as well.

There is a unique pride in being part of a community built around honor. You see this on the Swiss metro and in small-town vegetable stalls. Unproctored exams force every student to weigh the value of their honor against a better grade. That's a personal moral reckoning that might be worth the entire degree.
