When #AI tools hallucinate citations, their made-up author names are not random. "We show that #LLMs do not merely default to high-probability individual names when generating fictional experts: they produce correlated character ensembles, pairs and trios [of co-authors] whose co-occurrence rates far exceed chance and are consistent across independent generations." https://arxiv.org/abs/2606.02184 They fool people and tools: "We identify 1,655 ghost-authored records claiming nonexistent journals with fabricated publication dates…Server-side #DataCite timestamps prove deliberate backdating…These carry real #DOIs…making them harvestable by any scholarly aggregator that ingests DOI metadata." #Citations #Hallucinations #ScholComm
