Extract the claims
Separate facts, quotations, calculations, recommendations and predictions. Give each consequential claim its own line in a checklist. This prevents one verified statement from lending false credibility to the rest.
Go to the original source
- Open the linked page and confirm it exists and covers the same subject.
- Find the exact passage, table or announcement behind the claim.
- Prefer original documentation or data over commentary about it.
- If the source cannot be opened or does not contain the claim, mark it unverified.
- For important topics, seek an independent source that can confirm or challenge the interpretation.
Check time and context
- Is the source current enough for the question?
- Does an old statistic describe today’s situation?
- Does the guidance apply to the same country, product version or plan?
- Were exceptions, limitations or competing findings omitted?
Recalculate and compare quotations
Use a calculator or spreadsheet for totals, percentages and changes. Confirm the denominator and units before accepting a rate. For quotations, compare the complete wording and punctuation with the original; a shortened quotation must not change the meaning.
Communicate uncertainty honestly
- Use “verified” only for what you checked directly.
- Use “unverified” when a source is missing or inaccessible.
- Explain conflicting evidence instead of forcing one answer.
- When stakes are high, ask a qualified professional to review the material.
