Choosing trusted sources for company facts
Verification fails when sources are inconsistent or low quality.
Start with a clear hierarchy and treat media sources as secondary unless confirmed.
Source hierarchy
| Tier | Examples | Notes |
|---|---|---|
| Tier 1 | Official company site, docs, investor relations | Prefer for core identity and product facts |
| Tier 2 | Registries/filings (if applicable) | High authority where available |
| Tier 3 | Platform listings and app stores | Good for availability/specs |
| Tier 4 | Reputable media coverage | Use with caution; confirm with another source |
Practical rule
- For facts that can trigger reputational or legal risk, require at least two independent trusted sources and store both links.
