• ChatGPT generated comment, people need to know that they wouldn't be able to spot a well generated bit of text as AI these days. It's dangerous thinking they can. Was a nice touch when it called itself the slop machine though.

Scientific studies suggest that people usually cannot reliably tell whether a piece of text was written by AI from style alone: accuracy is often only slightly above chance, varies a lot by genre, and drops further for more formal or scientific writing. For example, one 2024 study found average accuracy of about 57% for texts overall, while a 2024 teacher study found that even novice and experienced teachers could not reliably distinguish ChatGPT essays from student essays and were often overconfident in their judgments; likewise, a study of research abstracts found reviewers were largely unsuccessful, with only 38.9% positive identification. There is some evidence that people can improve with explicit feedback and training, but the overall research points to the same conclusion: humans may sometimes pick up clues, yet unaided judgments about whether text is AI-written are generally weak and unreliable, especially when the writing is competent and domain-appropriate. - ChatGPT
