Episode notes
Limits of Understanding Biases
- Knowledge of cognitive biases explains errors retrospectively but does little to prevent them.
- Decision-making skills are situation-specific, relying on relevant mental models and experience.
Smarter Minds Rationalize Biases
- The smarter you are, the better you get at rationalizing poor decisions.
- Ego protection unconsciously drives reasoning over outcome optimization.
Delay Decisions for Clarity
- Avoid making decisions impulsively; take time to reflect and consider different perspectives.
- Walk around a problem mentally to view it from multiple angles before deciding.
