Why Repeated Claims Start to Feel True
A claim can feel more believable after repeated exposure, even when the repetitions do not add new independent evidence.
A normal situation
You see the same claim in a video, a post, a newsletter and an AI answer. After the fourth encounter it feels familiar and therefore safer to accept.
What is happening?
Familiar information is easier to process. That feeling of fluency can be mistaken for evidence, especially when several channels are repeating the same original source.
Repetition is cheap online. A weak claim can appear to have broad support when ten accounts, articles or generated answers all trace back to one source.
The useful lens
Illusory Truth Effect
This does not prove that one bias caused the decision. It is a useful lens for asking a better question and checking the evidence.
Evidence note: Repeated information is, on average, judged as more truthful than comparable new information. The size of the effect varies with the material and procedure, and repetition does not make every claim believable or erase all prior knowledge.
