2nd Order Consequences

Why do smart solutions so often create even bigger problems? From rent control that fuels housing shortages to social media designed to connect us but leaving us lonelier than ever, Second Order Consequences unpacks the hidden ripple effects of policies, technologies, and innovations that seemed like good ideas—until they weren’t. Blending psychology, economics, and systems thinking, this provocative and entertaining book explores why human decision-making tends to ignore second-order effects—and how we can learn to see them coming.

Second Order Consequences is a field guide to the unintended. Whether it’s the rise of automation, the pitfalls of well-meaning aid programs, or the paradoxes baked into urban planning and climate policy, this book equips readers with the mental models to ask the one question that changes everything: And then what happens? Perfect for fans of Malcolm Gladwell, Tim Harford, or Freakonomics, this is essential reading for anyone who wants to make smarter choices in a complex world.
