Where an argument does not last from Introduction to Conclusion, the reviewer&#8217;s objection is the reasoning, not the authorship.<\/li>\n<li><strong>Fabricated citations and references.<\/strong> References that do not exist, DOIs that resolve to unrelated papers, or real papers cited for claims they never made. This is verifiable in minutes, it is unambiguous, and it converts a vague concern into a documented finding.<\/li>\n<li><strong>Fabricated or misinterpreted data.<\/strong> Numbers that do not reconcile across text, tables, and figures; statistics inconsistent with the reported sample; effect sizes that no described method could produce.

Most of that gap comes down to how each test was set up. So before you trust an accuracy figure, look at what was actually tested.\u00a0The same tool can score 30 or 40 points higher or lower on accuracy, depending on how the test was set up:<\/p>\n<ul>\n<li>If you test an AI detector on output from older AI models, it will be more accurate than if you test it on output from newer AI models.<\/li>\n<li>Default single-shot prompts produce flatter, more detectable text than iterative, edited drafting. So it\u2019s easier for detectors to detect AI text that was generated at one go but not so easy to detect text that has been edited and refined by humans multiple times.<\/li>\n<li>Longer samples are easier to classify, so an AI detector performs worse on short text like abstracts and better on longer texts like theses.<\/li>\n<li>Often, the test set is half AI-generated and half human-written. This makes the AI detector look a lot more precise than it actually is. But such a test set bears no resemblance to what journals really receive, which could be a mix of completely AI-generated papers, papers with AI editing, papers translated using AI, and papers with no AI assistance at all.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Why_does_AI_detection_accuracy_reduce_as_new_AI_models_are_released\"><\/span>Why does AI detection accuracy reduce as new AI models are released?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Because detectors are trained on the output of earlier models, and different generations of models produce output with different statistical properties. Newer AI models produce a lot more variation and more idiosyncratic phrasing, which is precisely what older detectors were trained to read as human. <a href=\"https:\/\/link.springer.com\/article\/10.1007\/s40979-023-00140-5\">Elkhatat and colleagues<\/a> found that AI detection tools identified GPT-3.5 text more successfully than GPT-4 text.<\/p>\n<p>The drop in accuracy means that if your AI detector was highly accurate in 2023, there&#8217;s no guarantee that it&#8217;s still accurate at detecting output from 2026 AI models.<\/p>\n<p>Also,\u00a0<a href=\"https:\/\/link.springer.com\/article\/10.1007\/s40979-023-00146-z\">Weber-Wulff et al. (2023)<\/a> found that most tools are deliberately biased toward classifying text as human-written. That choice protects authors, and it also means roughly 20% of unmodified AI-generated documents in their test set were misattributed to humans.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Are_AI_detectors_accurate_for_human-written_text_edited_by_AI\"><\/span>Are AI detectors accurate for human-written text\u00a0<em><strong>edited<\/strong><\/em> by AI?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Hybrid drafting is now the common case, and it is the case detectors handle worst. Research on lightly polished human text shows that very small amounts of AI editing can trigger large jumps in flagging.<\/p>\n<p><a href=\"https:\/\/doi.org\/10.48550\/arXiv.2502.15666\">In a 2025 preprint<\/a>, a detector flagged human-written text with minimal AI editing as AI-generated. A serious implication of this finding is that simple AI-assisted proofreading over your own writing can make a detector flag your text as \u201cAI-generated\u201d.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"AI_Detector_False_Positives_and_the_Researchers_Most_Exposed\"><\/span>AI Detector False Positives and the Researchers Most Exposed<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A false positive is not a random event distributed evenly across a research community. False positives occur more frequently among specific groups and manuscript types, as explained below.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Why_do_multilingual_authors_face_more_AI_detector_false_positives\"><\/span>Why do multilingual authors face more AI detector false positives?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Because detectors treat linguistic complexity as a marker of human authorship, and second-language writers tend to use simpler, more standard constructions. That is the same profile as AI model output.<\/p>\n<p><a href=\"https:\/\/www.cell.com\/patterns\/fulltext\/S2666-3899(23)00130-7\">Liang and colleagues<\/a> tested 7 detectors on 91 human-written TOEFL essays. The average false-positive rate was 61.3%, at least 1 detector flagged 97.8% of the essays, and 19.8% were misclassified by all 7 tools simultaneously. Comparable essays by native English speakers drew near-zero false positives.<\/p>\n<p>Machine translation or AI-assisted translation compounds the problem. When human-written text in another language was translated into English, mean detection accuracy fell by roughly 20%, which places researchers who draft in their first language and translate at direct risk.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Formulaic_genres_methods_systematic_reviews_protocol_papers_and_ethics_statements\"><\/span>Formulaic genres: methods, systematic reviews, protocol papers, and ethics statements<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Some manuscript types are structurally machine-like, and their authors carry elevated risk regardless of language background.<\/p>\n<ul>\n<li><a href=\"https:\/\/www.editage.com\/blog\/conducting-and-reporting-systematic-reviews\/\">Systematic reviews<\/a> and <a href=\"https:\/\/www.editage.com\/blog\/meta-analysis\/\">meta-analyses<\/a>, where phrasing often follows the PRISMA guidelines about what should be reported and how.<\/li>\n<li><a href=\"https:\/\/www.editage.com\/blog\/registered-report-structure-checklist-examples\/\">Registered reports<\/a> and <a href=\"https:\/\/www.editage.com\/blog\/how-to-write-and-publish-a-study-protocol-meaning-examples-format\/\">study protocols<\/a>, which are formulaic by design.<\/li>\n<li><a href=\"https:\/\/www.editage.com\/blog\/randomized-controlled-trial-rct\/\">Clinical trial reports<\/a> following CONSORT, where standard sentences are effectively mandated.<\/li>\n<li>Ethics approval, funding, and data-availability statements, which are near-identical across manuscripts.

Individual editors and reviewers may also use consumer tools informally, which is a common and less visible source of author queries. However, the biggest concerns for editors and peer reviewers are not whether you used AI itself, but whether your paper has illogical text, fabricated citations, or misinterpreted data.
