These things are always so misguided, and this was no exception. The only way to have a piece of writing not flagged as AI is to write poorly. Ignore grammar, misspell words, etc. Don't follow basic guidance on composition. Generally write in such a way that you would merit no better than a C on a high school writing task.

I'll give some examples. Some will be from this list of "AI writing tropes" and some will be from prominent human-written (prior to 2020) sources. Guess which is which (answer at the bottom).

- "Let's explore this idea further."

- "workload creep"

- "Navigating the complex landscape of "

- "Let's delve into the details"

And I'm not going to get into how silly this is as a so-called LLM trope: "Every bullet point or list item starts with a bolded phrase or sentence." I remember reading paperbacks published before the first PC that used this style.

Fractal summaries is literally how composition is taught to students. Avoiding that style will make the writing more likely to sound less like a person wrote it.

I would suggest the author upgrade this to a modern version of Strunk & White and go on a mission to sell that. Call it Anti-Corpspeak or whatever. But don't pretend that these formulations only arrived in bulk in the last 2-3 years.

ANSWER KEY: these are all obviously prominent in text published before LLMs hit, as well as in the tropes doc. They are no more signs of LLM-generated text than is the practice of using nouns, verbs, and adjectives to convey ideas.
