Uncertainty, Fragility, and Responsibility

The five-volume Incerto investigates luck, uncertainty, probability, human error, risk, and decision-making under incomplete knowledge. The central lesson is not that prediction is difficult. It is that exposure matters more than confidence. When the future is uncertain, the intelligent response is not a more elaborate forecast — it is to limit ruin, preserve optionality, decentralise experimentation, align incentives, and build systems that learn from variation.
