What Counts as a Receipt? Match the Evidence to the Claim

A receipt is evidence a reader can inspect and connect to a specific claim. Its strength depends on what it establishes, how it was produced, and whether the conclusion stays within its limits.

Start with the question being tested

A recording can establish that a speaker used certain words. It does not automatically establish that the speaker's account is accurate. A photograph can document what is visible within a frame; identifying its date and location may require additional records.

Write the claim first. Then ask what kind of material would actually answer it. An impressive-looking document is not useful evidence if it addresses a different question.

Identify origin, context, and purpose

Look for the creator, date, original location, and reason the material was produced. Read surrounding passages and check whether you are seeing the complete item. The Library of Congress's analysis guides encourage observation, reflection, and questions about primary sources.

Firsthand material can still contain mistakes, advocacy, omissions, or limited knowledge. Treat its proximity to the event as something to assess, not a guarantee of truth.

Check whether confirmation is independent

Several articles repeating one statement do not necessarily provide several independent observations. Follow their citations backward. If they converge on the same interview or release, record that shared origin.

A useful evidence note might read: “Three reports cite one spokesperson; no separate document is linked.” That describes the sourcing without pretending the claim has already been disproved.

State the strongest supported conclusion

Separate what the material directly shows from what you infer. Explain the step between those two points. If an alternative explanation fits the same evidence, name the additional information that would distinguish them.

Keep a compact receipt file: the claim, original source, relevant passage, date, corroboration, limitations, and open questions. Readers should be able to reproduce the essential check without reconstructing your entire research process.
