Models can be fluently wrong: fake URLs, fake papers, stale policy wording, marketing treated as fact. For money, compliance, health, or law — treat answers as leads.
Checklist: 1) Demand clickable sources; dead links count as zero 2) Open 2–3 primaries; check units and dates 3) If sources conflict, list them — don’t average 4) Paste excerpts and force “answer only from materials” 5) Medical/legal: stop at “read the source / ask a pro”
Practice: ask a dated fact, require links, open them yourself. Then run the Research scene’s spot-check + conflict prompts.
