The 'adjacent possible', as articulated by Jordan Hall, refers to the boundary of potential transformations that lie just beyond the horizon of the present moment's reality. It is the space where innovation and evolution occur, encompassing not merely what is conceivable but what can actually be brought into being given the current constraints and resources. This concept captures the dynamic interplay between what exists and what can come into existence next; it is the realm where latent possibilities are activated through the intricate web of interactions within a system. The adjacent possible is not just a static threshold, but a continually shifting frontier that evolves as elements within the system interact, learn, and adapt in response to both internal and external pressures. It creates a scaffolding for strategic thinking, guiding individuals and collectives towards actions that are both visionary and feasibly executable.
