This book explores the origins, evolution, and practice of design fiction—creating tangible, evocative prototypes from possible near futures to examine decision-making consequences. As the world grows more complex and unpredictable, anticipating the future is no longer optional—it is essential. From climate change and economic instability to rising inequality and fragile institutions, uncertainty is everywhere. For too long, major decision-makers have viewed the future as a business exercise, engineering problem, or marketing tool. Design fiction offers an alternative: a way to materialize possible futures through artifacts that challenge assumptions, expand foresight, and reveal risks. This book provides a practical approach to integrating design fiction into strategy, research, and innovation.
