Does this sound like the set of challenges you might be facing?

  • Whenever a case pops up that contradicts what I believe, my reflex is to wave it away
  • I’m holding a belief tightly and I want to test it honestly, but I know that the second I go looking I’ll find whatever confirms it
  • I keep saying things like "X always leads to Y" or "people like that never change," and I pile up examples that fit
  • I have all these confident hunches about how things will turn out, but I never commit to a specific call in advance
  • My beliefs are all hedged into mush

Practices that may help

  1. Falsification Thinking
    Karl Popper argued that a claim is scientific — and useful — only if it can in principle be proven wrong. Falsification thinking applies this to everyday reasoning: instead of looking for evidence that confirms your view, ask what evidence would refute it. This is a well-regarded normative principle in philosophy of science; applying it in practice reduces confirmation bias and sharpens the precision of your beliefs.
  2. Weigh disconfirming evidence more heavily than confirming evidence
    One strong counterexample outweighs many confirming examples for a universal claim.

  3. Specify what would falsify your belief before you look at evidence
    Write down what evidence would prove you wrong before you go looking.

  4. Search deliberately for the black swan
