The theory, central to Taleb's work, that rare, high-impact, unpredictable events—Black Swans—shape history far more than ordinary, predictable events. A Black Swan has three characteristics: it is unpredictable (no one sees it coming), it has massive impact (it changes everything), and after the fact, we concoct explanations that make it seem predictable (hindsight bias). The theory argues that we are blind to Black Swans because we focus on what we know, on the predictable, on the bell curve—while history is made by what we don't know, by the unpredictable, by the outliers. The financial crisis of 2008 was a Black Swan: unpredicted by most models, catastrophic in impact, and afterward explained by experts who claimed they'd seen it coming. Black Swan Theory is the foundation of a worldview that expects the unexpected and builds systems that can survive it.
Example: "His models predicted steady growth forever. Then the pandemic hit—a Black Swan. Unpredicted, catastrophic, and afterward everyone claimed they'd seen it coming. Black Swan Theory had warned him to prepare for the unpredictable, but he'd ignored it. His models were beautiful and useless; the Black Swan had made them both."
