Evidence inspection

The full source was read rather than only a search snippet or abstract.
Definitions, sample, period, and jurisdiction match the proposed wording.
Quotations and figures were checked in their original context.
Linked evidence was opened and traced to the closest available primary record.
Circular citations or repeated copies were not counted as independent support.
Material limitations and uncertainty were captured for the draft.

Use decision

Disqualifying concern: [Describe or write None]
Corroborating source required: [Yes / No and why]
Decision: [Rely / Qualify / Corroborate / Background only / Reject]
Required attribution: [Write the attribution]
Required limitation: [Write the caveat]
Reviewer and date: [Name, YYYY-MM-DD]
Recheck trigger: [New version, policy change, scheduled date, other]

How to use this template

Copy the precise claim and define what a suitable source must establish.
Record the source's authorship, date, version, method, evidence, and interests.
Rate each dimension with a short reason instead of assigning numbers from intuition.
Identify any disqualifying gap and seek independent or more direct corroboration.
Make a documented use decision and carry necessary attribution or limitations into the draft.

Judge fitness for purpose, not prestige

Credibility is not a permanent badge attached to a domain. A government page may be authoritative for the rule it administers but not for an independent assessment of that rule's impact. A vendor may be the best source for its current product settings while remaining an interested party for performance comparisons. Write the claim you intend to support and the decision a reader may make from it before scoring the source. Then ask whether the author or institution is positioned to know that information, whether the evidence matches the claim's scope, and whether a more direct record exists. This claim-specific approach prevents reputation, attractive design, or search visibility from substituting for evidence.

Inspect the evidence trail and production method

Look beyond the headline and summary. Identify the named author, publication date, revision history, cited material, data collection method, sample, definitions, and limitations. For research, check whether the measures answer the question being asked and whether uncertainty is reported. For a policy or specification, confirm the version, jurisdiction, and effective date. For reporting, distinguish firsthand documents and interviews from repeated coverage that may trace back to one unverified statement. A source that openly describes its method and corrections gives a reviewer more ways to test it. Missing transparency does not automatically make a statement false, but it lowers confidence and may require corroboration.

Record conflicts, recency, and unresolved risk separately

Do not average every concern into one comforting number. A source can receive strong marks for authority yet still fail because it predates a product change, has a direct financial interest, or omits the population relevant to your reader. Use the score as a structured prompt, then make a written use decision: rely, rely with qualification, corroborate, use only for background, or reject. Document who funded or benefits from the claim, how recent the evidence must be, and which limitations belong in the published text. For high-consequence topics, follow the relevant specialist and editorial review process; this worksheet does not replace professional judgment.

Fictional example: software export limit

NoteNest and its documentation are invented. The example demonstrates why a primary source can still require a date qualifier.

Claim: “NoteNest exports up to 50 documents in one batch.”
Source assessment: The fictional product documentation is authoritative and direct, but the page has no visible revision history.
Decision: Rely with qualification after confirming the same limit in the fictional current interface.
Published wording: “As checked on July 30, 2026, NoteNest allowed up to 50 documents per export.”
Recheck trigger: Any export-interface release or the next quarterly review.

Frequently asked questions

Should I add the ratings into a single numerical score?

A total can help sort a large source list, but it must not hide a decisive weakness. Preserve the dimension notes and make the final fitness decision separately.

Is a primary source always the most credible source?

It is often closest to a fact, rule, or event, but it may be interested, incomplete, outdated, or difficult to interpret. Independent analysis can add context and verification.

Can social posts or community discussions be used?

They can document what a named person said or reveal questions worth researching. They rarely establish broader factual conclusions without authentication and additional evidence.

When should a source be checked again?

Set a trigger based on how quickly the information can change: a new product release, revised law, replaced dataset, correction, or a specific future review date.
