Episode notes
INSIGHT

Outcomes Don't Equal Good Decisions

  • Outcome bias makes us judge decisions by results rather than process quality.
  • Success can come from luck or context, so outcomes alone mislead about decision quality.
ADVICE

Evaluate Process Over Outcome

  • Judge decision quality by process and context, not just results.
  • Ask how a decision was made and look for evidence of sound procedure rather than assuming outcomes prove skill.
INSIGHT

Use Experts As Interpreters Not Oracles

  • Experts can be biased but still help interpret evidence.
  • Use experts to understand evidence, not as unquestioned sources of truth.
