Correct != Bug-free.

My experience working with software developed by academics is that it is focused on getting the job done for a very small user base of people who are okay with getting their hands dirty. This means lots of workarounds, one-off scripts, zero regards for maintainability or future-proofing...

“Incomplete” seems like a better word than “incorrect” for this. The code is likely correct in the narrow scope it was needed for, but is missing features (and error checking!) beyond the happy path, making it easy to use incorrectly.

This I fully agree with.
