The key finding here is the reversal of the relationship between writing complexity and paper quality.
Traditionally, sophisticated writing correlated with higher-quality research (or at least higher status/effort). This paper argues that post-LLM, we are seeing a flood of manuscripts that use complex, polished language but contain substantively weaker scientific contribution.
They claim LLM adoption increases output by up to 89%, which is a massive productivity shock. If the cost of generating looks-like-science prose drops to near zero, the signal-to-noise ratio in peer review is going to crash. We are entering the era of the polished turd, and likely worse case of publish and perish [0].
