The document discusses the importance of imagination and coordination in preparing for large disasters. It distinguishes between "black swans", rare events that are generally unimaginable, and "dragon kings", rare events that result from endogenous dynamics within socio-ecological systems and are therefore more imaginable and predictable. It argues that incentive structures within socio-ecological systems should encourage both imagination about potential disasters and coordination between different sectors in preparing for disasters. The key lesson is that incentive structures are important for encouraging people and organizations to consider unlikely but potentially catastrophic events.
