Adopted by: PolitiFact, FactCheck.org, Snopes, Full Fact (UK), Africa Check, and all IFCN-certified fact-checking organizations (90+ globally). Impact: IFCN signatories produce corrections that demonstrably reduce belief in false claims by 15–30% per experimental research (Nyhan & Reifler 2015); standardized processes reduce internal errors by 60%+ vs. ad-hoc verification. Why best: Fact-checking credibility depends entirely on process transparency; without a documented methodology, corrections lack authority.
Sources: IFCN Code of Principles (2016); Silverman "Verification Handbook" (2014); Poynter MediaWise curriculum; Graves "Deciding What's True" (2016).
Select the claim — identify a specific, verifiable, consequential claim. Prioritize: widely shared, made by influential figure, potentially harmful if false. Exclude: opinions, predictions, satire.
Record the claim verbatim — capture the exact wording, source, date, and context. Paraphrasing introduces distortion before verification begins.
Identify the claim type — categorize as: statistical/numerical, causal, historical, comparative, or definitional. Each type requires different verification approaches.
Trace the claim to its origin — follow the claim upstream to its original source. Most viral misinformation is a mutation of an older, sometimes legitimate, claim.
Find authoritative primary sources — for statistics: government datasets, peer-reviewed studies, official reports. For events: official records, contemporaneous documents, eyewitness accounts with documentation.
Consult subject-matter experts — identify experts with no stake in the outcome. Document their credentials and any potential conflicts of interest.
Apply the SIFT method — Stop, Investigate the source, Find better coverage, Trace claims to original context before concluding.
Reach the original claimant — contact the person or organization that made the claim. Request their evidence. Document all contact attempts and responses.
Apply a transparent rating scale — use a documented, publicly defined scale (True/False/Misleading/Unverifiable or equivalent). Apply the scale consistently across all checks.
Publish methodology with the verdict — explain what you checked, what you found, and why you reached your verdict. Link to all primary sources. Publish corrections prominently.
npx claudepluginhub jeffreytse/grimoire --plugin grimoireExtracts and verifies factual claims from PR copy or journalistic drafts, providing citations and warning on low certainty. Use before sending pitches or press releases.
Produces structured verification briefs for claims, breaking down assertions, identifying source types, red flags, and editorial judgment framework.
Verifies factual claims in text against authoritative sources using a cheapest-first cascade (project memory, codebase, web) and rewrites with footnote citations, hedging unverified claims.
