- Google incorrectly displayed a death notice for Jim Carrey on June 29, 2026, highlighting a failure in its knowledge system.
- Knowledge systems must balance trust and verification, as information becomes knowledge only after surviving scrutiny.
- Misinformation spreads faster than verification, especially with AI systems that can amplify false claims.
- Provenance and transparency are crucial; systems should track a claim's source, conflicts, and state over time.
- Verification should be proportional to consequence, with high-risk claims requiring stricter checks.
- Systems need to represent epistemic states like uncertainty or contradiction, not just true/false binary.
- Claims should have a lifecycle (asserted, supported, disputed, retracted) to reflect real-world changes.
- AI systems can obscure uncertainty by generating confident summaries from unverified sources.
- Trustworthy knowledge systems will be those that show provenance and allow correction, not just propagate information.
