s4h-investigation-triangulation
Verifies a claim across genuinely independent sources, distinguishing amplification from true corroboration. Use when you want to know if multiple sources actually confirm something — 'can I verify this from multiple angles', 'do independent sources agree', 'is this confirmed by more than one source', 'are these sources actually independent', 'how well-corroborated is this claim'.

# Investigation: Triangulation
More sources does not mean better verification. If ten publications all cite the same original study, you have one data point with ten references — not ten data points. True triangulation requires genuinely independent sources: different methods, different investigators, different populations, different time periods. Convergence among truly independent sources is strong evidence. Convergence among sources that all trace back to the same origin is amplification, not corroboration. This skill teaches the difference and makes it operational.

## Your Process
**Step 1: State the Claim**
Write out the claim you want to triangulate, precisely. Vague claims are hard to triangulate because different sources may be speaking to different aspects.
**Framing check:** Confirm the specific claim before continuing. State what you've identified — the actual claim being triangulated and its scope — in one sentence, then use `AskUserQuestion`:
- **Question:** "I'm reading this as: [your one-sentence framing of the claim and its scope]. Is that right?"
- **Header:** "Framing"
