A Simple Solution to Improve Broken Peer Review System at AI Conferences [R]

Summary

A Reddit user, isentropiccombustor, proposes a novel solution to mitigate reciprocal reviewing bias in AI conference peer review systems. The core idea involves dividing all authors and their submitted papers into two independent halves, A and B. Authors from half A would only review papers in half B, and vice-versa, ensuring that no reviewer evaluates papers from their own half, their coauthors, or coauthors of coauthors. Each Area Chair (AC)/Senior Area Chair (SAC) would also operate within only one half, with acceptance decisions made independently for each. Additionally, the discussion periods for the two halves would be staggered, for example, two weeks for half A followed by two weeks for half B, to prevent reviewers from managing their own papers concurrently with their review duties. This aims to remove the incentive for reviewers to unfairly reject competing papers.

Key takeaway

For AI scientists and research scientists involved in conference submissions and peer review, consider advocating for or experimenting with a split-half review system. This approach, by separating authors' submissions from their review assignments, directly addresses reciprocal reviewing incentives and could improve review fairness. While not a panacea for all peer review issues, it offers a testable mechanism to enhance integrity and reduce competitive bias, potentially leading to more equitable paper acceptance.

Key insights

Splitting conference submissions and reviewers into independent halves can reduce reciprocal reviewing bias.

Principles

• Independent review pools reduce direct competitive bias.
• Staggered review periods improve reviewer focus.

Method

Divide authors/papers into two halves (A/B), ensuring authors from A review only B, and vice-versa. Place all coauthors in the same half. Stagger discussion periods for each half.

In practice

• Pilot this split-half review system at a smaller conference.
• Model outcomes using historical conference data.
