The question
Before ChatGPT, which kinds of human writing already used the words and habits now called AI-isms most, and when did each become common?
The sample
17,000 pieces of writing from before ChatGPT: 6,600 web pages in 16 kinds of writing, 103 homepages, 10,000 arXiv abstracts, 600 passages from pre-1928 books, Google Books 1800 to 2019

§ IFindings of fact

What the study found.

  1. Before ChatGPT, press releases used AI-isms such as "innovative", "pivotal" and "seamless" 3.7 times as often as news articles: 1.61 against 0.44 uses per 1,000 words in pages from 2021 and earlier (ScriptGrain, 2026).
  2. Words that studies of scientific writing found language models over-use, including "innovative", "advancements", "pivotal", "delve", "meticulous", "underscore", "comprehensive", "potential", were most common in press releases in writing from before ChatGPT.
  3. The sentence shapes associated with AI writing, such as "not X but Y" and reflexive lists of three, were most frequent in pre-1928 speeches (2.07 per 1,000 words) and sermons and religion (1.94), against 0.45 in UK news.
  4. "Delve" was rare in 2021 news everywhere: it appeared on 3 of 600 Nigerian news pages, 1 of 600 Kenyan, and none of 1,000 UK and US pages.
  5. In English-language books, "innovative" went from 0.14 to 12.12 uses per million words between 1950 and 1980; "transformative" rose 31 times between 1980 and 2019, long before ChatGPT.
  6. Before ChatGPT, "delve" appeared in about 1 in 5,287 arXiv abstracts (1,057,471 abstracts from 2015 to November 2022 with no later revision); only 3.5% contained any of the twelve words later identified as 2024 AI tells.
  7. "Delve" was already 3.0 times as common in English-language books in 2019 as in 1980 (Google Books).
  8. 40 of 43 words now called AI-isms were more common in English-language books in 2019 than in 1980.
  9. Of 26 kinds of writing measured, a Q&A forum (English Stack Exchange) used AI-isms least: 0.04 per 1,000 words, 37 times less than press releases.

    Nigerian news pages used "delve" (2021)

§ IVThe finding

The finding

The "AI voice" looks less like an invention than an inheritance: the vocabulary of corporate announcements laid over the rhetorical shapes of older speeches and sermons.

§ VQuestions for the court

Asked and answered.

Where did the AI-isms come from?

From human writing. Before ChatGPT, press releases used AI-isms 3.7 times as often as news (1.61 against 0.44 uses per 1,000 words), and the sentence shapes called AI were most frequent in pre-1928 speeches (2.07 per 1,000 words) and sermons (1.94).

Were AI-isms rising before ChatGPT?

Yes. 40 of 43 words now called AI-isms were more common in English-language books in 2019 than in 1980. "Transformative" rose 31 times between 1980 and 2019.

Did "delve" come from Nigerian English?

The evidence does not support it. In 2021 news, "delve" appeared on 3 of 600 Nigerian pages, 1 of 600 Kenyan and none of 1,000 UK and US pages: rare everywhere, and the difference was within chance.

How was it measured?

17,000 pieces of writing from before ChatGPT: 6,600 web pages in 16 kinds of writing, 103 homepages, 10,000 arXiv abstracts, 600 passages from pre-1928 books and Google Books 1800 to 2019. Counted with deterministic code, never a language model.
