The American Association for Cancer Research analysed 7,177 manuscripts submitted to its 10 journals and found 36% of abstracts contained at least some AI-generated text. Evidence suggested four times as many authors use AI as disclose it — and peer reviewers were using it too, despite being asked not to.
Benefits & outcomes
One of the first hard numbers on undisclosed AI use in submissions: 36% of abstracts, with disclosure running at a quarter of actual use.
