Students are often fully aware their use of ChatGPT is a bad idea. Like the gambling addict, that doesn't mean they stop. Forcing yourself to do your schoolwork has always been difficult, and they've been given a way out.
Often and fully aware? I sincerely doubt it. I’d bet it’s only a tiny minority of students who use ChatGPT who think it’s a bad idea.
Unlike the gambling addict, they can’t feel the immediate repercussions of their actions. Those will only be available in hindsight, long after they can correct.
You can’t test this type of awareness with polls. Doing the study itself skews the results.
