Oxford Comma users: people may think AI does your writing

9 October 2024

Frequent use of the Oxford Comma, also referred to as the Serial Comma, is — apparently — a tell-tale sign a written work was composed using an AI chatbot. The repeat use of punctuation mark is among seven indicators researchers at Cambridge University, in the United Kingdom, identified after studying AI generated articles and essays.

As a life-long adherent of the Oxford Comma — read enough of the content here, and you’ll notice them — this alarms me. AI doesn’t write a word here, every Oxford Comma instance you see in my copy, was placed by me. On the up side, at least ChatGPT has the good taste to use the Oxford Comma in the first place.
