How to Write a One-Sentence Investigation Claim

Key Takeaways

The method	Write one falsifiable sentence — actor, action, timeframe — before you collect a pile of files.
Why it matters	Vague claims produce vague reporting; sharp claims tell you which record to request next.
On Gnosis	The claim sits at the top of your investigation and Evidence Board so readers see what you are testing.

Every investigation needs a north star readers can hold you to. On Gnosis that sentence is the claim: not a topic (“housing”), not a mood (“corruption”), and not a question you hope someone else will answer. It is a statement that could turn out false once the records land.

Editors and solo investigators waste weeks gathering screenshots that never attach to a testable assertion. Fix the claim first; the archive becomes a checklist instead of a junk drawer.

What a working claim contains

Aim for one sentence with:

• Actor — a named person, agency, company, or defined group.
• Action or state — what they did, approved, omitted, or spent.
• Scope in time or place — enough that a record set could cover it.

Optional but powerful: the source type you expect (“according to the city’s executed contract,” “per the FY2025 budget schedule”). If you cannot imagine the PDF, spreadsheet, or docket entry that would settle most of the sentence, rewrite it.

Bad claims vs better ones

Weak: “The city mishandled homelessness.” — No actor precision, no period, no falsifier.

Better: “In FY2025 the city’s housing department spent less than 40% of its allocated emergency shelter funds, according to the published expenditure report.” — Now you know which report to open and what number to check.

Weak: “Tech companies invade privacy.” — Topic, not claim.

Better: “Between March and June 2026, Company X’s public privacy policy still stated it does not sell personal data while its developer docs described a paid data API for advertisers.” — Two documents; conflict is checkable.

Stress-test before you publish

Ask:

1. Could a careful reader disprove this with one primary record?
2. Am I smuggling opinion adjectives (“reckless,” “corrupt”) that belong in analysis, not the claim?
3. If I remove the dependent clauses, does a core sentence remain?

When the claim is still a fog, split the project. Two sharp investigations beat one sprawling unfinished one.

How Gnosis uses the claim

In the product, the claim is the headline of the case you are building. Evidence pins should support, complicate, or contradict that sentence — not decorate a vibe. Readers who open a free investigation should see the claim and enough of the trail to decide whether you earned trust.

Do this next on Gnosis

Grab the free Investigator Starter Kit and fill the claim box before the source list. Then start an investigation on Gnosis with that same sentence at the top.

Claims that survive contact with records

A good claim anticipates the first counter-document. If the agency publishes a corrected expenditure table next week, does your sentence still have a fair reading, or did you overclaim? Prefer measurable verbs: spent, approved, filed, omitted, stated. Soften with attribution when needed (“according to the published report”) rather than with fog (“raised questions about”).

Write the claim on a sticky note and keep it visible while you FOIA and interview. Every task should either support, complicate, or kill that sentence. If a day’s work does none of those, you are decorating the folder again. When the claim must change, rewrite it explicitly — do not let the headline drift while pins still point at the old sentence.
