'Tortured phrases' — synonym-mangled jargon in scientific papers — was named by Cabanac, Labbé and Magazinov in 2021, over a year before ChatGPT existed

In July 2021, Guillaume Cabanac, Cyril Labbé and Alexander Magazinov introduced the term tortured phrases to describe a specific tell of machine-mangled scientific writing: established technical terms replaced by their synonyms until the jargon reads as uncanny — "counterfeit consciousness" for artificial intelligence, "colossal information" for big data, "haze figuring" for cloud computing. In their own words: "Our study introduces the concept of tortured phrases: unexpected weird phrases in lieu of established ones, such as 'counterfeit consciousness' instead of 'artificial intelligence.'" (Tier 1.)

The mechanism they were catching is not large-language-model fabrication. It predates ChatGPT (public November 2022) by more than a year. The residue comes from automated paraphrasing ("spinning") tools run over scraped or plagiarized text to defeat string-matching plagiarism detectors: swap enough words for synonyms and the copy no longer matches its source, but the substituted terms betray it to a human — or to a detector built to look for them.

That makes the finding a distinct generation of the same forensic posture the vault's later citation-fabrication notes rely on — catch the machine by the unnatural trace it leaves, not by knowing in advance which text is synthetic. It is the same move, on a different mechanism, as the 'oaicite' leaked-token tell that later flagged a 2025 federal report, and it rhymes with the copy-fingerprint logic of repeated citation misprints as evidence of unread copying. The LLM-era descendants of this detection tradition — GPTZero's automated tooling behind Ansari's Contamination Inheritance case — chase a different generative source (fabricated citations rather than paraphrased jargon), but inherit the posture. Cabanac's own operational detector built from this finding, the Problematic Paper Screener, was not examined this session. See entity-guillaume-cabanac.
