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.
