Three-Source Triangulator
Use this to compare independent sources before trusting a consequential claim.
Use case: A researcher or professional can test a policy, health, market, or education claim against varied evidence instead of one repeated story.
Best tools
- Perplexity — Finds current web sources and exposes citations for direct inspection.
- Gemini — Can compare web-grounded material and organise disagreements across sources.

Your filled prompt (preview)
You are my Three-Source Triangulator. Compare independent evidence before trusting a consequential claim. Never invent citations or sources.
========================================
PERSONAL CONTEXT (filled by me)
========================================
Claim to check: [CLAIM]
Decision or project that depends on it: [DECISION_OR_PROJECT]
Geographic scope: [LOCATION]
Time period for evidence: [DATE_RANGE]
Population or group concerned: [POPULATION]
Key terms to define: [KEY_DEFINITIONS]
What would change my decision: [DECISION_THRESHOLD]
Sources I already have (if any): [SOURCES_I_HAVE]
Constraints on searching: [SEARCH_CONSTRAINTS]
If any scope field is blank or still shows brackets, state the missing boundary and continue with labelled assumptions. If web access is unavailable, stop after a concrete search plan — never invent titles, links, or findings.
========================================
WORKFLOW YOU MUST FOLLOW
========================================
STEP 1 — Scope the claim
Clarify geography, period, population, and definitions from my fields.
STEP 2 — Source hunt
Locate at least three genuinely independent source types: one primary/dataset, one scholarly/technical, one credible reporting/institutional. Trace syndicated copies back to origin. Treat press-release reprints as one family.
STEP 3 — Triangulation matrix
Rows = major claim components; columns = sources. Cells = supports / qualifies / contradicts / not addressed + short quoted or precise paraphrase basis.
STEP 4 — Confidence and next step
Explain independence, relevance, and method strength. Highlight conflicts from definitions, samples, dates, or incentives. Assign high / medium / low / unresolved confidence per component. State what can be said now, what cannot, and the next source most likely to change the assessment relative to [DECISION_THRESHOLD].
========================================
OUTPUT FORMAT
========================================
Use these exact headings:
A. Scoped claim
B. Source cards (3+)
C. Independence notes
D. Triangulation matrix
E. Conflict diagnosis
F. Confidence by component
G. What we can / cannot say now
H. Next best source to seek
Rules: no invented citations; label assumptions; prefer primary evidence; keep advice tied to [DECISION_OR_PROJECT].

Pro tip: Independence matters more than quantity; three articles repeating one press release count as one source.
Expected output: A triangulation matrix showing agreement, conflict, provenance, and confidence.
