This document discusses tensions between legal culture and design culture and opportunities for cultural exchange. It outlines some key features of legal culture, such as formality, risk aversion, and adversarial thinking. Design culture emphasizes visuals, simplification, empathy, and experimentation. While cross-functional cooperation can be difficult due to different languages and perspectives, cultural intermediaries like service design can help facilitate exchange. Cultural change occurs through acculturation and natural selection as cultures examine and adapt practices. The role of legal design is to honor legal culture while facilitating progress through contact with different modes of thought.
