A reliable way to make people believe in falsehoods is frequent Short excerpt

How we verified this

  • Wikiquote identifies the exact sentence in “Cognitive ease,” p. 62.
  • The publisher supplies an inspected introduction describing the book’s purpose: recognizing recurring errors in judgments and choices. That excerpt provides context, not the quoted page.
  • No original image of the cited page was inspected, so the precise book location is reported through Wikiquote rather than claimed as directly verified.

Context

Why it mattered

Thinking, Fast and Slow examines how intuitive judgments can feel convincing before they are carefully examined. In the chapter “Cognitive ease,” the cited sentence links repetition with familiarity and apparent truth. The point concerns a vulnerability in judgment, not evidence that every repeated claim is false.
