Im Reinen sein - Gefiltertes Leben: Wie viel Gutes ist zu viel?
Summary
Liv Apollonia Schabatzke explores how the modern obsession with filtering air, light, and information stems from evolutionary negativity bias. The essay traces the history of filtration from survival tool to commercialized anxiety, arguing that digital echo chambers and state nudging erode our tolerance for ambiguity. Ultimately, it advocates accepting life’s inherent messiness, as true resilience requires engaging with, rather than eliminating, irritation and risk.
