uncorroborated

Uncorroborated is an adjective describing information, claims, or testimony that has not been supported by independent evidence or verification from additional sources. It implies that, at the time of assessment, no corroborating documentation, witnesses, or data have confirmed the assertion.

In journalism, uncorroborated statements are treated with caution; reporters typically seek corroboration before presenting information as fact. In scientific research, uncorroborated results are usually regarded as preliminary and require replication or independent confirmation. In legal contexts, uncorroborated testimony may carry less weight than corroborated evidence; the weight afforded to such testimony varies by jurisdiction and context.

Evaluating uncorroborated material involves assessing source credibility, seeking independent verification, examining potential biases, and considering the possibility of error or deception. When information remains uncorroborated, responsible communicators may label it as unverified or pending corroboration rather than presenting it as established fact.
