AI-Generated References: How to Identify Fabricated Citations

AI tools can produce references that look real but do not exist, or that mix details from different papers. Always verify each reference by finding the actual article in a trusted database and reading enough of it to confirm that it supports your claim.

Warning signs

• The authors, title or journal sound plausible but you cannot find the paper.
• A DOI or PMID that does not resolve, or resolves to a different article.
• Mismatched details: correct title but wrong journal or year, or authors who did not write about the topic.
• Perfectly formatted references for obscure topics with no search results.
• A claim in the text that the real paper does not make.

Verification steps

1. Search PubMed or another database for the exact title in quotation marks.
2. Check the DOI by entering it into a resolver; confirm that the page shows the same title, authors and year.
3. Check the PMID or PMCID in PubMed, if given.
4. Open the journal page and confirm volume, pages and article type.
5. Read the abstract, or preferably the relevant section, to confirm it supports your statement.
6. Import verified items into a reference manager from the database record, not by retyping.
7. Remove or replace any reference you cannot verify.

If you find a fabricated reference in a submitted manuscript

Tell the journal and correct it; do not leave it. Journals may treat fabricated references as a research-integrity concern.

Illustrative example

Invented for teaching. An AI tool lists "Smith J et al., J Clin Hypertens 2019;21:1234", but PubMed shows no such article. The DOI leads to a different paper on kidney disease. The student discards the reference and searches for real studies using the PubMed workflow.

Common pitfalls

• Verifying only that the journal exists.
• Citing from an abstract you have not read.

Key takeaways

• Verify every reference in a database and read what you cite.
• Import from the source; never trust AI-generated citations.
