ABSTRACT
Do we need a theory to justify or explain how people make plans for places? I think not. Each person learns how to make plans growing up. This plan-making ability is part of the legacy of human evolutionary adaptation and cultural learning. Imagining the consequences of future action enables humans to consider what to do before doing it. Most human behavior follows contours of cultural tradition and social experience that people acquire at home, school, and work. These habits provide psychological fuel for the multitude of social routines people follow. Planning emerges as uncertain and unexpected events disrupt this continuity. People use imaginative conjecture to compare and assess potential responses. People plan.
