[gotcha] AI-generated citations and URLs look valid but are fabricated hallucinations users trust and click

Never render AI-generated citations, references, or URLs as clickable verified links without runtime verification. Display them as plain text with a clear AI-generated not verified label. For any URL, perform a HEAD request to verify it resolves before making it clickable. For academic citations, cross-check against a real database if possible.

Journey Context:
LLMs generate citations that are structurally plausible — correct formatting, real author names, realistic-sounding titles, valid-looking DOIs — but completely fabricated. The URL might point to a 404, the paper might not exist, or the real author may never have written that title. The UX failure is rendering these as if they are verified: blue underlined links, formatted reference sections, source badges. Users click through and hit dead ends, or worse, cite the fabricated reference in their own work. This has caused real-world harm: in Mata v. Avianca \(2023\), attorneys submitted ChatGPT-fabricated case citations to a US federal court and faced sanctions. The counter-intuitive part: making citations look more polished \(clickable links, formatted references\) increases user trust in fabricated content. The fix is to treat all AI-generated references as unverified by default and only elevate them to verified status after programmatic checking. This adds latency and complexity, but the alternative is your product helping users propagate misinformation.
