thearchivist.funSource triangulation
Triangulation is useful when several kinds of evidence address the same question from different directions. An announcement can establish what was promised, a preserved interface can show what a user saw, and an account from a participant can explain an experience. Agreement matters only after considering what each source can actually support. Do not count three pages as three confirmations when they all copy one release. Map the source relationships and look for evidence that could challenge the claim. A disagreement may reveal that sources describe different dates, regions, versions, or definitions rather than that one is simply dishonest. In a research note, identify the proposition each source addresses and the remaining gap. The goal is a better-supported explanation, not a numerical vote among search results.
