The AAAI 2027 organizers have confirmed what many researchers have suspected for years: collusion in the review process is real, and it often takes the form of 2-cycles, where authors review each other's papers. The decision to address this openly is a meaningful step, but the conversation that followed reveals how tangled the issue has become. One Reddit user pointed out that because most submissions come from a single country, the assignment algorithm is more likely to create these 2-cycles among authors from that country. They stopped short of naming the country, citing a fear of being labeled racist. That fear is telling. It suggests that the integrity of peer review is now a minefield where legitimate concerns about process are overshadowed by the risk of being misunderstood.
We should not let that fear distract us from what matters. The core problem is not the nationality of the authors involved; it is the structural incentive to game the system. When a conference receives a large volume of submissions from one region, the algorithm that matches reviewers to papers will naturally produce more 2-cycles there. That is not an accusation against any group of researchers. It is a mathematical reality. The AAAI organizers deserve credit for acknowledging the issue, but acknowledgment is not the same as action. As we explored in Clean Data Starts With Catching AI Slop Before It Skews Your Model, detection and filtering are only as good as the underlying assumptions. If the review process relies on flawed or incomplete signals, the outcome will reflect those flaws.
There is also a broader point about reproducibility that often gets tangled in these discussions. The Reddit user noted that some papers accepted at top conferences like NeurIPS, ICLR, and ICML do not have code published on GitHub. That observation is worth sitting with. If the community spends substantial time reimplementing methods just to verify results, the bottleneck is not only collusion. It is a culture that rewards novelty over transparency. We have written about the practical side of building ML systems, such as in Exploring Real-World Computer Vision: Deployments, Edge Models, and Current Challenges, where the gap between a paper's promise and its real-world deployability often comes down to missing details. Collusion and missing code are two symptoms of the same underlying issue: a system that optimizes for acceptance rates rather than scientific soundness.
What would we tell a reader who asks whether this matters for their own work? It does, more than you might think. If you are building on top of published research, you are already inheriting the incentives of the original authors. When a paper claims a result but does not share code, you are not just losing convenience. You are losing the ability to verify. And when review processes are gamed, the papers that get accepted are not necessarily the most rigorous ones. They are the ones whose authors understood how to navigate the system. The Forrester function is a useful reminder that mathematical tools can be used in unexpected ways, but only when we understand their limits. The same applies to peer review.
The open question is whether AAAI will release the statistics on submission numbers and reviewer assignments. Transparency here would go a long way. Without data, the conversation stays stuck in speculation, and the fear of being labeled something you are not will keep people from asking the hard questions. The concrete detail to watch is whether the organizers follow their acknowledgment with action. If they publish the numbers, we will have a baseline. If they do not, the silence will be an answer in itself.
