AI generated plagiarism detectors are going to have to get better. Even Claudine Gay’s own allegations weren’t completely accurately plagiarism because they ranged from insufficient rewording to - yes - unquoted passages. So if she can claim that the quotations weren’t accurate or the citations weren’t appropriate, then…it really is all for grabs if “academic meta-journalism” is just a high level google search right now.
None of which ever really challenged her work overall or conclusions or points she substantiated. Which should be the total point.
