This chapter introduces the concept of Digital Anthropology as a critical framework for understanding and designing 6G communication networks. Rooted in complex systems theory, Digital Anthropology analyzes how human behaviors, social interactions, and emergent dynamics influence and are shaped by digital infrastructures. The chapter explores the propagation of information and misinformation, the co-evolution of network structures and social behaviors, and the impact of collective dynamics on communication resilience and trust. By integrating insights from social contagion models, higher-order network theory, and adaptive intelligence, the chapter presents Digital Anthropology as a practical approach for the development of human-centric, resilient, and ethically aware 6G systems. It concludes by aligning these insights with the broader goals of Society 5.0, emphasizing the transformative role of complexity science in enabling inclusive, adaptive, and socially responsive communication infrastructures.
