AgentReview: Exploring Peer Review Dynamics with LLM Agents
Paper · 2024 · Yiqiao Jin, Qinlin Zhao, Yiyang Wang et al.
Summary
Studying peer review empirically is hard. Outcomes depend on many interacting factors, some important ones such as reviewer bias or motivation are hidden, and real review records are confidential. AgentReview addresses these problems by simulating conference reviewing entirely with LLM agents playing reviewers, authors and area chairs. The simulation follows a five-stage pipeline: initial reviews, author rebuttal, reviewer–AC discussion, meta-review, and an accept/reject decision at a fixed 32% acceptance rate. Researchers can vary one factor at a time:
- Reviewers: commitment, intention and knowledgeability.
- Area chairs: authoritarian, conformist or inclusive style.
- Authors: whether their identity is visible to reviewers.
The authors ran this on 500+ ICLR submissions from four years. They found that a single biased reviewer can shift about 37% of decisions, and that rebuttals matter less than reviewer traits. They interpret these effects through sociological ideas such as conformity, groupthink and authority bias. Because the setup needs no real reviewer data, it offers a privacy-safe testbed for designing review mechanisms. However, the simulated outcomes were not validated directly against actual human reviews.
Key points
- The resource contains more than 53,800 generated documents (reviews, rebuttals, revised reviews, meta-reviews and decisions), including over 10,000 reviews. Code is at github.com/Ahren09/AgentReview.
- Involving one biased reviewer changes 37.1% of decisions. Letting ACs rely on their own judgment changes 30.6%.
- After discussion, rating spread shrinks by 27.2% (standard deviation) as reviewers drift toward consensus. One under-committed reviewer lowers overall commitment by 18.7%.
- Revealing author identity for just 10% of papers alters 27.7% of decisions. Biased reviewers lower ratings by 0.17 among themselves and also pull unbiased reviewers' ratings down by 0.25.
- When numeric ratings are hidden from the AC, the set of accepted papers overlaps only weakly with the baseline (Jaccard 0.20). The authors caution against using LLMs as substitutes for human reviewers.
