GoKawiilStudy finds Perplexity search citations often lack the cited figures
An audit of Perplexity's Sonar and Sonar-Pro models tested 310 factual questions about 210 tech companies and checked every citation attached to a sentence containing a number. It found that 34.7% of 1,826 such citations linked to pages that either wouldn't load or didn't contain any of the figures stated in the sentence, though scoring by claim rather than by individual citation marker lowered the failure rate to 14.4% of 872 claims.
GoKawiil's interpretation of the reporting above, not reported fact.
This matters because Perplexity presents itself as a more trustworthy, source-backed alternative to plain chatbot answers, yet the audit shows its inline citations frequently fail to actually support the numbers they're attached to. Since only 1.3% of links were simply dead, the bigger problem is unreadable or irrelevant pages being cited as proof, which undermines the core promise of verifiable AI search.
- 34.7% of citations tied to numeric claims pointed to pages that didn't open or lacked the cited figure
- When judged per claim instead of per citation marker, the failure rate drops to 14.4% of 872 claims
- Dead links account for only 1.3% of failures; most problems are inaccessible or irrelevant source pages
The Chicago Guide to Fact-Checking by Brooke Borel — If an audit finding a third of AI citations don't support their numbers makes you want to verify things yourself, this is the standard handbook on how professional fact-checkers actually chase a claim back to its source. It walks through sourcing, documentation, and the discipline of confirming that a cited page really says what it's cited for — exactly the step the models skipped.
