What is triangulation in source analysis?

• A. Relying on a single source
• B. Ignoring contradictions
• C. Using multiple sources or types to verify information; strengthens reliability and reduces bias
• D. Accepting hearsay

Answer: (C)

Triangulation in source analysis means using multiple sources or kinds of evidence to verify information. By comparing what different sources say, a historian can check for consistency, confirm details, and uncover biases or gaps. This approach makes conclusions more reliable because independent sources that agree strengthen confidence, while differences prompt deeper investigation into context, perspective, or origin.

For example, studying a historical event would involve official records, contemporary newspapers from various viewpoints, personal letters or diaries, and later scholarly work or artifacts. If these sources converge on the same timeline or cause, that consensus boosts credibility. If they diverge, it signals a need to examine why—perhaps propaganda influenced some accounts, one source was incomplete, or perspectives shifted over time.

Relying on a single source misses the cross-checking that triangulation provides. Ignoring contradictions avoids a fuller understanding, and treating hearsay as solid evidence is not a trustworthy basis for conclusions.
