>Some of these students are dishonest. Many aren't. Many genuinely believe the work they submit is their own, that they really did do the work, and that they're learning the languages. It isn't, they didn't, and they aren't.

People are quite poor at this kind of attribution, especially when they're already cognitively overloaded. They forget sources. They mistake others' ideas for their own.

This attitude is common not only among students, in my experience many people behave this way.

I also see some parallels to LLM hallucinations..
