Frequently Asked Questions
How big is the citation hallucination problem?
Studies of GPT-3.5: 47% of medical citations were fabricated. GPT-4: ~18%. Even when names + years are real, DOIs + journal names are often wrong. Critical risk for students/researchers.
Can ANY citation from AI be trusted?
Never without verification. Even when "real", the AI may have misattributed findings or cited the wrong paper for a claim. Always Google Scholar / DOI-resolve every citation.
Best workflow?
1) Generate cite with AI, 2) Search Google Scholar by author+year, 3) Verify the cited claim is in the actual paper, 4) Always include DOI in final write-up.
