Re-evaluating a belief

Annie Duke lays out a series of questions we can ask ourselves about a given belief1:

  • How do I know this?
  • Where did I get this information?
  • Who did I get it from?
  • What is the quality of my sources?
  • How much do I trust them?
  • How up to date is my information?
  • How much information do I have that is relevant to the belief?
  • What other things like this have I been confident about that turned out not to be true?
  • What are the other plausible alternatives?
  • What do I know about the person challenging my belief?
  • What is their view of how credible my opinion is?
  • What do they know that I don’t know?
  • What is their level of expertise?
  • What am I missing?
