Will AI Replace 70% of Peer Reviewers by 2030?
A 2023 survey from STM Reports revealed that over 15 million peer reviews are conducted annually—but with submission rates climbing and reviewer pools shrinking, scientists and publishers are asking: can AI ease the burden, or will it simply replace reviewers altogether?
AI is quickly making inroads into the traditionally human-driven process of academic peer review. From fraud detection to improving transparency, artificial intelligence is already performing tasks that once required hours—if not days—of expert human scrutiny. But what does this really mean for the future of quality control in scientific publishing?
🧠 Smarter Screening, Faster Decisions
One of AI’s most immediate use cases in peer review is automating administrative and quality checks. Tools powered by natural language processing (NLP) can now scan manuscripts for plagiarism, flag statistical inconsistencies, and ensure compliance with reporting guidelines like CONSORT or PRISMA.
According to Enago, AI has helped reduce initial screening times from several days to just a few hours by automating routine checks. This not only speeds up the journey from submission to publication but also ensures that only high-quality articles reach human reviewers—enhancing both efficiency and fairness. For overburdened journals, that’s a game-changer.
📊 Bias Buster or Black Box?
AI can also play an active role in mitigating bias in the review process. By automatically anonymizing manuscripts and filtering reviewer matches based on expertise rather than personal connections or prestige, AI introduces a layer of objectivity that human editors may struggle to maintain consistently.
As noted by PMC, algorithms can help editors select reviewers based on quantifiable expertise rather than reputation, which could reduce favoritism in the process. But there’s a catch: how those algorithms make their decisions isn’t always transparent. For every bias AI eliminates, it may introduce another.
This has led to pushback from some researchers, with platforms like The Scholarly Kitchen cautioning against overreliance on opaque systems that lack accountability.
🌍 Bridging Global Gaps
Here’s where things get interesting. AI isn’t just about efficiency—it could lean into equity.
Global participation in peer review has historically been skewed toward English-speaking and institutionally well-connected scholars. But according to the BMC Series Blog, AI-powered translation and drafting tools are helping non-native English speakers contribute more confidently. For instance, large language models can assist reviewers in writing clearer, more structured reports across languages—lowering barriers for researchers from the Global South or non-traditional academic pathways.
That means a more diverse pool of reviewers, better representation of global perspectives, and potentially higher-quality peer feedback rooted in real-world applicability.
🔍 Cross-Disciplinary Clarity
Another under-discussed but powerful application of AI in peer review? Handling complexity across disciplines.
AI tools can scan papers for methodological red flags or misapplied statistical models, a task that might otherwise require multiple specialized reviewers. As pointed out by the Science Blog, this could help peer review teams efficiently vet cross-disciplinary research without compromising quality. For example, a computational biologist submitting a paper to a bioethics journal could benefit from AI catching nuanced errors that might escape less specialized human reviewers.
This isn’t just a boost in speed—it’s a leap in robustness.
🤖 So—Will AI Replace 70% of Peer Reviewers?
Not entirely. According to industry experts at Scholarly Kitchen, a hybrid model is more likely: one where AI streamlines repetitive tasks and highlights issues, while human reviewers focus on conceptual judgment, originality, and ethical reasoning. It’s about augmentation, not automation—at least for now.
Still, a significant shift is underway. With estimates that over 70% of peer review workflows could be AI-assisted by 2030, roles will change. Reviewers may spend less time on rote analysis and more on higher-order critique. Editors will work more like data interpreters than gatekeepers.
Yet concerns linger. Confidentiality breaches, algorithmic bias, and loss of reviewer mentorship are challenges that demand thoughtful governance. As SL Guardian reports, some scientists fear that AI may erode the craft of reviewing—the unseen labor that sharpens science itself.
🎯 Looking Ahead
The question isn’t whether AI will be part of the peer review process—it’s how much trust we’re willing to place in it.
Will the next scientific breakthrough be shepherded by a human, a machine, or both? As emerging tools evolve to do more of the heavy lifting, the peer review process we’ve known for over 300 years may not survive unchanged—but it may finally catch up to the pace of 21st-century science.

The real question might be: are we ready to embrace a future where peer review isn’t just faster—but fundamentally different?
Conclusion
So as AI quietly reshapes peer review—from weeding out statistical errors to bridging global gaps—it’s worth asking: if machines begin shouldering the burden of judgment, what happens to the judgment itself?
When algorithms grow skilled at spotting flaws and sharpening structure, do we risk offloading not just tasks, but our sense of responsibility and critical engagement? Peer review has always been a deeply human enterprise, rooted in debate, skepticism, and the messy pursuit of truth. What does it mean when that messy process becomes optimized?
Perhaps the real question isn’t whether AI will replace 70% of peer reviewers by 2030, but whether we’ll still recognize what peer review means by then. In handing over efficiency, are we also rewriting the values baked into scientific discourse—rigor, accountability, collective scrutiny? As AI tightens the system, we may gain speed and polish—but will we lose the human pulse that drives discovery?
The future of peer review isn’t just a tech story; it’s a reflection of what kind of truth-seeking community we want to be.
