I submitted a paper with a reference author as Elisio because I couldn’t read my own handwriting. After submitting, I double checked all the references through an LLM. It pointed out that their name was actually Enrique. Yes, you should probably double check your references before submitting, not after.
Point is, I didn’t even trust the LLM at first. But after verifying the mistake, I was embarrassed af. I resubmitted with the fixes before it went live, but ultimately, what’s the difference between “mistake” and “hallucination”?
With proper bibliography management tools, everything (that has one) is centered around the DOI.
In fact, if a DOI is present, it's trivial to verify authors, title, venue, year, pages etc.
Of course, some older and more obscure papers won't have a DOI, but the vast majority of research work has.
