Ludic Fallacy
The Ludic Fallacy is the error of applying the simplified, well-defined rules of games and models to the complex, messy, and unpredictable real world. Coined by Nassim Nicholas Taleb in "The Black Swan" (2007), this mental model explains why risk models fail during financial crises, why chess masters struggle with real-life decisions, and why academic theories often break down in practice. Understanding the Ludic Fallacy allows decision-makers to recognize when they're confusing the map with the territory and to design strategies that account for true uncertainty rather than modeled risk.
