“Nut-free” is the hardest claim for AI to verify.
CITAQ verifies it.
Negative claims — what a product does not contain or does not do — are the primary purchase decision in food, supplement, and cosmetics markets. CITAQ verifies them the same way it verifies positive claims: evidence submission, evaluation, and cryptographic record.
AI agents are trained on positive assertions. Absences are invisible to them.
The internet describes what things are. Rarely what they are not. When a shopper asks ChatGPT “which protein powder is safe for celiac disease,” the AI must cross-reference negative claims across potentially thousands of products. Without verified negative claim data, it faces three bad options:
A verified negative claim changes this entirely. An AI agent querying a product with a CITAQ-verified “gluten-free” claim backed by an ISO/IEC 17025 accredited allergen test receives a deterministic answer: VERIFIED, L5, [lab name], [date], [hash]. The agent responds with confidence.
The stakes in this category are not marketing stakes. A wrong allergen recommendation in food is a potential health emergency. AI systems are strongly incentivised to preferentially cite verified sources. Verified negative claims become the highest-confidence citation available for high-liability queries.
An absence requires active proof. CITAQ maps the evidence requirements.
You cannot prove an absence from a description. CITAQ requires active evidence for negative claims. The evidence level required depends on the claim's safety implications.
Acceptable for: Non-GMO declarations, general 'free-from' marketing claims.
Not acceptable for: Allergen-free claims with safety implications.
Acceptable for: Intermediate allergen claims.
Acceptable for: Allergen-free claims (nut, gluten, dairy, shellfish, soy). Drug-interaction-free claims. Contaminant-free claims in supplements.
The evidence level determines how the AI agent treats the response. L5 evidence produces the highest confidence citation. L2 evidence produces a qualified citation. No evidence produces a SUPPRESSED state.
Hundreds of billions of dollars in annual commerce depend on negative claims.
For merchants in these markets, the negative claim is often the only claim that matters:
In all of these categories, approximately 45% of health-conscious consumers make purchasing decisions based on allergen or ingredient absence claims. AI agents in these categories are answering more queries than any other shopping assistant touchpoint.
CITAQ's verified negative claim infrastructure is a direct commercial asset for these merchants — not a compliance exercise.
