Citation needed. I have seen these kinds of assertion all my life without any evidence to back them up. For example, when I moved to the US, I was told, again without any evidence, Chinese students cheat a lot. It's always a couple of faculty who extrapolate their experiences with a few students and then slap racial labels on the entire student body.

Exactly; A voice of sanity at last!

Notice that these sort of "racist rumours" only started in the last few years and not before. AI has simply lowered the threshold for _everybody_ to take-shortcuts/cheat etc. and nothing specific to any one group other than statistical numbers.
