Adapt
Tim Harford’s *Adapt* dismantles the myth of top-down perfection, arguing that trial and error—not rigid plans—is the driving force behind progress in complex, uncertain worlds. Drawing on vivid examples from biology, economics, military strategy, and innovation, Harford shows how spontaneous order (as Hayek theorized) and iterative testing solve problems that experts and leaders can’t. From the 'toaster project' exposing global supply chain complexity to General McMaster’s successful decentralized tactics in Iraq, from Muhammad Yunus’s iterative microfinance breakthroughs to the risky bet that spawned the Spitfire fighter plane, the book demonstrates that failure isn’t a setback—it’s critical data. It also warns of the dangers of tight-coupled systems (like banks and nuclear plants) where mistakes cascade into catastrophe, advocating for loose coupling and structured experimentation. For individuals, Harford explores how to overcome cognitive biases that deny failure, embracing 'ordered diversity' to adapt and thrive.
