I would not agree with this from my own experience. The truth is the culture, at least at Brown in the 2020s, has little stigma around cheating in big classes. Unclear how different this is in the past, but a friend and I often joke that the student body is very good at reward hacking. If there's a reward, people will find a way to get it! That's across grades (people will cheat), housing (a huge % people will competitively apply for specialty housing or accommodations to beat the lottery), and a whole lot of other things. I don't think this is correlated with legacy, athletics, ect. but an artifact of the current culture unfortunately.
