Faced with the growing pressure for performance and efficiency, how can we reinvent higher education? Inspired by the idea of the detour rather than speed, this lecture explores the experimentation of a dual interdisciplinary Bachelor's degree launched at Sciences Po. Through deliberate slowing down—extended curricula, inquiry-based learning, and the intersection of disciplines—this initiative questions our methods of knowledge transmission and contemporary training imperatives. Between pedagogical reflection and feedback, the goal is to ask: what should we be training for today? And how should we go about it?
