The Three Tomorrows of Postnormal Times is a new method for foresight and futures researchers and practitioners. Designed and developed to explore the complexity, chaos, and contradictions of postnormal times and what might come next, the three tomorrows method uses a multi-layered approach to situate and analyze trends, emerging issues, and imaginings of the future(s), including complex, horizonspecific forecasts. In this paper, we provide a theoretical overview of the key concepts underlying our approach, including the three forms of ignorance and uncertainty as well as the Menagerie of postnormal potentialities, which we developed as a mechanism for challenging deeply held convictions, illuminating entrenched contradictions, and enlivening novel considerations.
