Why repetition can make false claims feel true
Launch library · evergreen read
Psychological research has long observed that repeated exposure to a claim tends to make it feel more familiar and, as a result, more genuinely believable, regardless of whether the claim itself is actually accurate or not. This effect can occur even when a person initially recognised the claim as false.
This dynamic makes repetition a particularly effective tool for spreading misinformation, since simply encountering a false claim multiple times, even in contexts explicitly correcting it, can inadvertently reinforce familiarity with the underlying claim itself rather than the correction offered alongside it at the same time, an effect that catches even careful readers off guard.
Being aware of this effect encourages a more deliberate approach to evaluating repeated claims, focusing on the underlying evidence rather than how familiar or widely repeated a particular claim happens to feel after encountering it several times across different contexts and platforms over a relatively short period.
