New Phenomenology serves as a foundation for the book’s conceptualization of sense-making of risk and uncertainty. It distinguishes between reflexive, symbol-mediated forms of knowledge and non-reflexive, embodied certitudes, arguing that all are indispensable for understanding how people make sense of uncertain situations. Through engagements with Schmitz and, with reference to selected writings of Schütz, the chapter develops an epistemological framework in which subjective self-givenness through bodily experience and situational embeddedness form the basis of all objectified knowledge. It highlights the phenomenological gap between lived experience and institutionalized abstractions, showing why rationalized knowledge may fail to resonate with individuals’ experiential worlds. By integrating the problem of relevance, habitualization, and the temporal–spatial structure of sense-making, the chapter demonstrates how New Phenomenology helps explain the interplay between rational, non-rational, and in-between modes. This framework lays the groundwork for a more complex conceptualization of people’s understanding of risk and uncertainty.
