What is the purpose of corroboration in research?

• A. It speeds up work.
• B. It guards against bias and inaccuracy by cross-checking with multiple sources.
• C. It reduces costs.
• D. It ensures only primary sources are used.

Answer: (B)

Corroboration in research is about confirming findings by checking them against multiple independent sources. This approach guards against bias and inaccuracy because no single source should determine the truth; independent sources can reveal errors, misinterpretations, or biased reporting. By cross-checking data, quotes, or conclusions across different sources, researchers build a convergence of evidence that makes the results more trustworthy and credible.

Context helps: corroboration often involves triangulation—using different methods, data sets, or sources to verify a finding—and is closely related to replication and peer review. For example, a trend observed in a study is more convincing if other studies, official records, or qualitative data collected in different ways point to the same conclusion.

The other ideas aren’t the primary aim of corroboration. It isn’t mainly about speeding up work or reducing costs, since the extra checking takes time and resources. And it doesn’t require using only primary sources; corroboration can involve primary and/or secondary sources as long as the goal is to verify accuracy through multiple independent lines of evidence.
