We find that similar patterns emerge with random treatments, neutral keywords, and several placebo tests. We also provide a formal proof of the mechanism and reproduce the same pattern in simulations.

On the effect of LLM adoption on researcher productivity, you might find the comment we released today interesting: arxiv.org/abs/2605.17979

The core issue is that the treatment variable (being classified as an LLM adopter) is mechanically related to researchers’ publication volume: the more papers an author publishes, the more likely they are to be classified as treated.

Similar “LLM effects” can be reproduced when replacing “LLM adoption” (detected from abstract content) with random keywords, random treatment assignment, or even publication periods predating the release of ChatGPT.

🚨 A few months ago, a paper published in Science reported that “LLM adoption is associated with a large increase in researchers’ scientific output.” In a comment released today, we show that the reported effects are driven by a methodological issue in the empirical design. arxiv.org/abs/2605.17979
