A more accurate title might be "Average University Students Can't Identify Czech AI Poetry". The random-chance performance seen here is reminiscent of the 50-50 nonexpert performance measured in "People who frequently use ChatGPT for writing tasks are accurate and robust detectors of AI-generated text".

I would have been really interested to see someone explore whether greater exposure to non-poetry AI text generalizes to greater ability to sniff out AI poetry as well, but sadly this was not that sort of study.
