My feeling is people in west extrapolate asian within group variations into whole. Rich international students who invest in western degrees as pay-to-win not representative / sampling bias vs whole. Reality is international students pay for degree, university accommodates, lack of language proficiency = they'll visibly "cheat" more (i.e. patch writing) to get what's theirs, but those conditions to specific subculture/cohort. Broad statistically show western institutions has like 15-50% plagiarism/cheating rates, most of which just get swept under rug because academic misconduct not elevated officially to keep misconduct stats at ~1%. For reference PRC plagiarism data (CNKI / big data audit used to sweep through tertiary thesis) was like ~10%.

I suppose one conclusion is academically inclined East Asians cheat less in aggregate... because broadly you can't cheat national examinations (yes there are very elaborate cheating rings, but this should only reinforce it's not easy / trivial). The ones who buys academic performance, i.e. dummies who can't hack PRC tertiary and has to go western tertiary (including Ivys) cheat more than baseline. But broadly west cheats more... but institutions minimize misconduct stats because incentivized to cover/underreport/juke stats to protect brand.
