Inquiry · As of October 18, 2026

Who judges expert work when AI does the work?

Expertise has always rested on judgment: knowing which question matters, which result holds up, and which paper is worth reading. AI can now draft research, review it, and summarize it at a scale no field was built for. This inquiry follows what happens to that judgment: whether AI can tell research that matters from research that is merely correct, what the flood of AI-assisted papers does to experts' signals, what happens to peer review when reviewers use AI too, and who gets to decide what counts as legitimate.

How the judges got overwhelmed, in order

Can AI judge what research matters?

Correct is not the same as interesting. At Agents4Science, AI-written papers passed AI reviewers and a human round, and the experts' verdict was that they were "neither interesting nor important." When independent scientists checked one AI scientist system's reports, 85.5% of its statements about data analysis were accurate, but only 57.9% of its interpretations, the step where someone decides what a result means.

Judgment can be trained narrowly. A fine-tuned model predicted which of two research ideas would work better more often than human experts (64% against 49% in one field), while off-the-shelf models did no better than chance. Models trained on where papers were published learned to predict publication tier, which raises the question of whether they learned quality or gatekeeping.

The flood

In computer science, up to 17.5% of paper text showed LLM modification by early 2024. A study in Science of 2.1 million preprints found that scientists who adopt LLMs publish 23.7–89.3% more papers, and that LLM use reversed the old link between polished writing and paper quality: papers became "linguistically complex but substantively underwhelming."

Some of the flood is worse than mediocre. Output from paper mills is doubling every 1.5 years, against every 15 years for science as a whole. Formulaic papers built on one public health dataset went from about 4 a year to 190 in most of 2024. GPT-fabricated papers already appear in Google Scholar results.

Reviewing at scale

Reviewers are using AI too, often against the rules. In ICML 2026's own survey, 22.5% of reviewers who had agreed to a ban used an LLM anyway. AAAI-26 gave every one of 22,977 submissions an AI review in under a day, and participants preferred those reviews on technical accuracy.

The risks are specific. AI reviewers agree with each other too much, and rewriting a paper with an LLM raises its AI review scores without changing the science, which researchers call "paper laundering." The most defensible use found so far is AI coaching human reviewers: at ICLR 2025, reviews updated after AI feedback were rated more informative, and acceptance decisions did not change. Asking authors to rank their own papers predicted citations better than review scores did.

Who decides what counts?

Fields are drawing lines. Conferences say only humans can be authors and that authors answer for every word. arXiv now gates review papers, though one study finds ordinary research papers contain more AI-generated papers by count. When a lab claimed GPT-5 had solved open math problems, the keeper of the problem list showed within hours that it had found existing solutions.

Legitimacy also fails on evidence about AI. MIT disowned a widely cited paper claiming AI made materials scientists far more productive, and materials chemists disputed whether 2.2 million AI-predicted crystals counted as discoveries at all. An anthropologist and a cognitive scientist warn of "illusions of understanding": science that produces more and understands less.

In practice: experts working with AI

The same questions show up wherever experts use AI. In a medical trial, GPT-4 alone outscored physicians, and giving physicians GPT-4 barely improved their diagnoses. Experienced developers were 19% slower with AI while believing they were 20% faster. Whether AI levels novices up or rewards experts depends on the task: it lifted call-center novices most, while an AI mentor helped strong entrepreneurs and set back weak ones.

Skills can fade too. Endoscopists' detection rate on procedures done without AI fell after their clinics introduced it, and senior engineers report that junior colleagues ask them fewer questions. Employment for 22- to 25-year-olds in the most AI-exposed jobs has fallen, which raises the question of how the next experts will be trained.

How this inquiry was made

This page was made with AI, which is part of its subject. AI agents searched for sources and opened each one to check its title, date and figures. A model chose the excerpt passages, word for word, from each paper. Another wrote synthesis notes and the lines of inquiry that connect this collection to the rest of the library, and drafted this page. Where sources disagree, the page says so instead of choosing.

A human curator chose the question, asked that it lead with questions any expert would recognize instead of specialist studies, and picked which research directions to show and which lines to feature under each.
