In this episode, we unpack the concept of "post-truth" as presented in 21 Lessons for the 21st Century by Yuval Noah Harari. Rather than being a new phenomenon, Harari argues that humans have always relied on shared fictions—religions, national myths, ideologies, and brands—to foster large-scale cooperation. The real challenge today is not the existence of fictions but the difficulty in discerning reality from myth in a hyperconnected, information-rich world. We explore how truth competes with narratives, why people often choose power over facts, and how promoting scientific thinking—and even science fiction—can help rebuild trust in reality.
