Source-to-claim mapping keeps an article honest by showing which evidence supports which statement. It is especially valuable in a daily cadence, where a familiar statistic can otherwise move from draft to draft without its original context.
List claims before polishing
Highlight statements that depend on external facts: measurements, dates, definitions, standards, and reported behavior. Record each claim in a small evidence table before refining the prose.
| Claim field | What to capture | | --- | --- | | Exact meaning | What the sentence asserts | | Source | Original publication or standard | | Scope | Population, period, and method | | Limitation | What the evidence cannot establish | | Decision | Keep, narrow, replace, or remove |
Prefer direct evidence
Use first-party studies, official documentation, standards, and original datasets when available. A secondary explanation can help interpretation, but it should not silently replace the underlying source for a consequential number or rule.
Preserve uncertainty
If evidence supports association rather than causation, write that distinction. If the source studies a different population, name the gap. Editorial usefulness comes from accurate boundaries, not from making every conclusion sound universal.
Start with the source readiness check and use Google’s people-first content guidance to review whether sourcing serves the reader.
Frequently asked questions
Does every sentence need a citation?
No. Cite material external claims and distinguish them from local process recommendations or clearly labeled analysis.
What happens when a source disappears?
Record the access issue, seek an authoritative replacement, and revise or remove unsupported claims rather than citing a broken memory of the source.
