Practical Examples

1. Thinking in Probabilities Instead of Certainties

   Duke illustrates making decisions by evaluating the likelihood of outcomes instead of seeking definitive answers. For example, when making business or life choices, assign probabilities to possible results and decide accordingly. This method helps to guard against overconfidence and binary (right/wrong) thinking.

2. The Dangers of Resulting

   She discusses the cognitive bias called 'resulting,' in which people judge a decision based solely on its outcome rather than on the process behind it. Just because you win a risky bet doesn’t mean it was a good decision. This is crucial for learning from both good and bad outcomes in an unbiased way.

3. Using Groups for Better Decision Making

   Duke highlights creating 'truthseeking pods,' or small groups of trusted peers who candidly challenge each other's thinking and assumptions. By encouraging honest, constructive feedback, you increase the likelihood of reaching better outcomes and reduce the influence of personal biases.

4. Separating Luck from Skill

   The book emphasizes analyzing which factors in your results were due to your skill and which were simply luck. For example, a well-played hand in poker can lose due to bad luck. Understanding this distinction helps people improve, not by results, but by process refinement.

5. Accountability to Reduce Bias

   Duke recommends announcing your predictions or decisions ahead of time and tracking results. For instance, make your reasoning explicit and share it with others to hold yourself accountable, reducing self-serving bias and hindsight bias.

6. Reframing Mistakes as Learning Opportunities

   She encourages treating mistakes not as failures but as vital data for honing decision-making skills. Each misstep becomes feedback, so you can iteratively improve your choices in the future.
