Strong shared narratives provide coordination, identity, and meaning. However, when those narratives become too rigid or too heavily defended, they reduce the system's ability to update in response to new realities (technological, environmental, or social). Conversely, narratives that change too easily or too frequently lose their coordinating power.
Hybrid systems must develop the capacity to maintain "adaptive narrative stability" — narratives that are coherent enough to guide action and identity, but revisable enough to evolve without catastrophic loss of meaning.
