A reliable way to make people believe in falsehoods is frequent repetition, because familiarity is not easily distinguished from truth.

This statement aligns with Kahneman’s work on cognitive biases and how people use mental shortcuts when judging what is true or credible, especially under uncertainty or limited attention.

Repeating a claim can make it feel more believable because the mind tends to treat ease of recognition and processing as a cue for accuracy, even when the claim is wrong.
