Quick answer: Extract the three most important claims, verify each against a current primary source, and check whether the answer omitted a condition that changes the conclusion.

You do not need to investigate every sentence equally. Focus verification on the claims that drive a decision or could cause harm if wrong.

What matters most

  • Prioritize consequential claims
  • Search exact names and numbers
  • Check the source date
  • Recalculate important figures

A practical step-by-step approach

1. Mark key claims

Highlight the facts that support the main recommendation.

2. Find primary sources

Prefer official documentation, filings, research papers and direct announcements.

3. Check recency

Make sure the source applies to the current version, country or period.

4. Recompute numbers

Use a calculator or spreadsheet rather than trusting generated arithmetic.

5. Look for omitted conditions

Ask what would make the advice wrong or inapplicable.

Try it in practice

Check a number and its context

Suppose a draft says a subscription costs 20 per month and 200 per year. Multiplying 20 by 12 gives 240; the annual figure may reflect a discount, a different currency or an error. Open the actual pricing page and identify which condition explains the difference.

Illustrative exercise, not a measured test result.

What to check before you decide

Evaluate claims by authority, independence, freshness, specificity and whether another reliable source reaches the same conclusion.

  • Original source
  • Matching context
  • Current date
  • Reproducible math
  • Known uncertainty

Common mistakes to avoid

  • Checking only the easiest claim
  • Accepting a citation without opening it
  • Ignoring geographic differences
  • Treating confidence as evidence

A question worth asking

What if five minutes is not enough?

Treat five minutes as triage, not a guarantee. Pause publication or the decision when an important claim remains unverified.

Your next step

A short verification pass can expose important errors, but it is not a guarantee. If evidence is unavailable, state the uncertainty and pause any consequential decision.
