0% TurnItIn score, should I be worried?
I recently wrote a paper for school that our professor told us to NOT DO RESEARCH FOR. So, the content had to come all from our brains and no other sources at all. I submitted my paper and saw it had a 0% turnitin score. At first I thought that was really good, but then I started looking it up online and people keep saying it's an even bigger indicator that there is something wrong with my writing if it's completely at 0%?? Why is that? I know turnitin often flags citations and stuff and thats why its common for the percentages to be within like 10-30% give or take, but I wasn't allowed to use any outside research so nothing like that was flagged for my paper. Is that bad?
EDIT: Sorry if this is a stupid question. I was recently accused of using AI in another class for a very simple writing assignment that I just misread small instructions for, and I'm very anxious about having to talk to the professor after class about it even though I know I didn't do anything wrong. I've been a good academic writer for as long as I've been in school and have never had issues like anything like this, so this is new and stressful to me. It just feels so wrong for these new tools to be brought in and assumptions being made about me because of them.
