Domain-stratified trust
The bar a claim must clear is set by its domain — the cost of being wrong — not by how casually or urgently it was asked.
- High-consequence domains (medical, legal, financial, scientific) demand independent primary or credentialed sources.
- Low-consequence, subjective domains (recipes, product picks, opinion) may validate by broad independent consensus.
- A confident tone or expert phrasing never lowers the bar; the domain does.
- Cap a claim's trust score when it fails its domain's minimum source, however plausible it sounds.
- "Candy bars cure colds" must score as untrustworthy because the medical bar is high — independent of who asks.
