It likely is, but that’s also on the assumption every author has to be in association with an institution and it’s quick to verify that.
What good reason is there for trust in authorship to be low? I would likely agree for if it’s related to llm-slop.
Plagiarism, fictional data, and unreproducible results have been a problem for a some time, and LLMs are now increasingly standing in authors’ shoes. In a system that rewards production over all else, people are naturally going to be incentivized to cut corners.
Some cultures that are increasingly participating in the scientific process don’t even agree as to what the ethical boundaries are.
