Peer review has a clarity problem, and it is not the one most people assume. When a paper reports strong technical results but buries them in weak writing, the instinct is to separate the science from the style. That instinct is wrong. Presentation is not a cosmetic layer applied after the real work is done; it is the architecture that makes the work legible. A paper with no citations in its introduction is not just poorly written. It is failing to situate itself in the very conversation it claims to join, and that failure is a scientific one.
The reviewer who raised this question is right to be troubled. If the experimental results are solid but the authors cannot articulate what is new, how do we verify the novelty? Without context, we are left to guess whether those impressive numbers represent a genuine advance or a rediscovery of something already known. This is not a minor editorial gripe. It is a fundamental breakdown in scholarly communication. As we explored in our coverage of How smart reviewers use compute power to validate published results, verification relies on reproducibility, but reproducibility depends first on clarity. You cannot replicate what you cannot parse. The same principle applies here: you cannot evaluate what you cannot situate.
The temptation is to lower the bar for presentation when the numbers look good. Resist it. Accepting a paper that cannot explain its own contribution does a disservice to the authors, who never learn to communicate their ideas effectively, and to the field, which accumulates unanchored results. A major revision is not a punishment. It is an invitation to build the scaffolding that the work deserves. In fact, we have seen how AI Is Reshaping the Peer Review Process for Better or Worse, and one clear risk is that automated tools will paper over these structural weaknesses with fluent prose while the underlying logic remains broken. That would make the problem worse, not better.
The specific takeaway for reviewers is this: treat the introduction as a hypothesis statement, not a formality. If the authors cannot map their work onto the existing literature, the work is not ready for publication. Strong results without strong framing are like a high-performance engine installed in a vehicle with no steering wheel. The power is real, but the direction is missing. Demand the steering wheel. That is how peer review protects the integrity of the field, not by punishing bad grammar, but by insisting that every contribution earns its place in the conversation.
