The document discusses the concept of "exposure" in designed culture and how it relates to designing products and services for developing nations. Exposure occurs when different social forces converge in a way that violates a user's social norms, boundaries, and sense of control. When designing for developing nations, exposure can happen when solutions are designed through a top-down approach without understanding users' experiences and context. To limit negative exposure, the document suggests applying Dewey's framework of designing for experience, where users have significant control and participation in shaping their interactions and the objective conditions of the designed culture.
