O capítulo "Armadilhas de Crenças" enfatiza que as crenças devem estar sujeitas a mudanças e que é fundamental estar aberto a discussões com outras pessoas que tenham crenças diferentes. As razões psicológicas para as armadilhas de crenças incluem o viés de confirmação e o viés de desconfirmação, que favorecem as informações que apóiam uma crença e desconsideram as informações que se opõem a ela, respectivamente. O método científico é apresentado como a melhor maneira de inventar e avaliar crenças, e expor as próprias crenças às críticas fundamentadas de outras pessoas é um antídoto eficaz contra as armadilhas de crenças.


  1. The importance of being open to changing beliefs: The chapter emphasizes that our everyday beliefs should be tentative and subject to change based on new information and discussions with others.

  2. The danger of intellectual isolation: Surrounding ourselves only with like-minded individuals can lead to belief stagnation or even more extreme beliefs, as we may not be exposed to different perspectives.

  3. Psychological obstacles to belief change: Confirmation bias and disconfirmation bias interfere with impartial belief assessment, making it difficult to change our beliefs even when presented with evidence.

  4. Doubt as a valuable defense: Embracing doubt and uncertainty, like the physicist Richard Feynman suggests, can help protect against belief traps and promote a more curious and open-minded approach to life.

  5. The role of reasoning in evaluating beliefs: While reasoning can help reveal inconsistencies in our beliefs, it is important to be aware of the potential for motivated reasoning and reasoning errors that can lead us astray.

  6. Belief expansion as a tool for challenging beliefs: Expanding a belief by filling it out with related beliefs can present difficult challenges and help us better understand the implications and potential inconsistencies in our beliefs.

  7. The significance of beliefs in decision-making: Our beliefs can greatly impact our personal well-being, parenting, and civic responsibilities, making it important to critically examine and modify our beliefs when necessary.

  8. Science as the best way to invent and evaluate beliefs: The chapter argues that the scientific method offers the most reliable approach to understanding the world, as opposed to relying solely on intuition, inner feelings, or revelations.
