Why Five Sources May Still Be One Source
Five apparently separate sources can create false confidence when they all depend on the same original claim.
Source count is not source independence.
Repeated reporting can amplify one error without adding new evidence.
The useful question is whether corroboration comes from genuinely independent evidence origins.
A reliable review records dependence rather than treating repetition as confirmation.
Why this matters
This matters whenever a decision depends on a widely repeated claim that has not been traced back to its evidence origin.
