A confidence level tells you how much to trust a figure, based on source reliability, freshness and corroboration.
A confidence level tells you how much to trust a figure, based on source reliability, freshness and corroboration.
| Confidence | What drives it |
|---|---|
| High | A reliable source, collected recently, often corroborated elsewhere |
| Medium | A reasonable source, but ageing, or with no corroboration |
| Low | A weaker source, stale, or where sources disagree |
Notes
A low-confidence figure is not necessarily wrong, only less certain. Treat it as a starting point to verify rather than a fact to rely on directly. See When two sources disagree for one common cause of lower confidence.
