A widely repeated claim is not necessarily true.
Repetition can increase familiarity. It does not supply evidence that a claim is correct.
Show me why
Ten posts repeating one source are not ten independent observations. Research on the illusory truth effect finds that repetition can affect perceived truth, even when repetition does not improve accuracy.
A common misconception
Popularity, familiarity and independent corroboration are different things.
Where the limits are
A repeated claim can be true. This is a reason to check evidence, not to reject popular statements automatically.
How we know
The cited experimental research examines changes in truth judgments. Separately, the logical point is straightforward: repeating a statement changes how often it is heard, not the evidence for its content. Trace a claim back to its original basis.
What would change this conclusion?
A specific claim deserves a different conclusion when supporting or conflicting evidence changes; repetition alone is not that evidence.
