This chapter explores “Zuversicht“(confidence/trust) from an emotion theoretical perspective, integrating it with the theory of antifragility. The author examines the etymology and cultural significance of Zuversicht in German-speaking contexts, highlighting its distinction from related notions such as hope and optimism. The neurobiological foundations of Zuversicht are investigated, suggesting potential links to brain regions associated with emotion regulation and decision-making. Zuversicht is proposed as an adaptive mechanism, fostering resilience and personal growth in the face of uncertainty. The integration of Zuversicht and antifragility offers a novel framework for understanding human adaptation and flourishing amidst adversity. This interdisciplinary approach synthesises insights from emotion research, neuroscience, and positive psychology, providing a comprehensive examination of Zuversicht as a multifaceted phenomenon with implications for individual well-being and social cohesion. The chapter concludes by outlining potential avenues for future research in this emerging field.
