We’re Losing Smell Literacy

Modern life (urbanization, sanitization, processed food, and screens) has eroded people's practical ability to interpret smells — a form of cultural knowledge that used to guide food choices, safety (spoiled food, gas, smoke), and social meaning. This sensory illiteracy affects memory, public‑health signals (think anosmia reporting), culinary culture, and leaves a practical gap for technologies that aim to monitor environments. — Loss of collective smell knowledge reshapes public health, food and safety norms, and pushes responsibility for sensing onto institutions and tech — altering regulation, industry practices, and AI design choices.
