This lesson discusses Nassim Taleb’s book, “Antifragile- Things That Gain From Disorder,” and focuses on the concept of antifragility. Antifragility exists on a spectrum with fragility and robustness and describes things that gain from randomness, uncertainty, stressors, errors, and time. Interventions that remove stressors can turn antifragile things into fragile ones, and detecting fragility and antifragility is possible by examining concavity and convexity. The lesson also discusses the barbell strategy, which involves securing oneself against huge losses while having exposure to a large potential upside, and the importance of minimizing downside to maximize potential upside. Finally, the lesson explores the answer to the Black Swan problem and how to change a system from being fragile to robust or antifragile.
