On certainty, evidence, and the courage to be wrong

This book asks a deceptively simple question: what evidence would be enough to make us reconsider something we feel certain about?

For the Practical Retiree Lab audience, the topic is central. Good retirement decisions, good science, and good use of AI all require the same discipline: separating confidence from evidence.

  • Explores intellectual humility without treating uncertainty as weakness.
  • Connects evidence, belief revision, and clear public reasoning.
  • Useful for readers who care about science literacy, disagreement, and better judgment.

Available on Amazon as Kindle eBook and paperback.
