Thinking Sideways: A Plea for “Weak Theory”

Abstract

This essay examines the implications of interdisciplinary debates on the power of “weak theory” for planning practice. Focusing on the North American planning context, I argue that the concept of “weak theory” – with its emphasis on specificity and mid-level generalizations and its openness to doubt and contingency – has long been a source of discussion about social interventions, but the significance of this approach for understanding cities and informing city planning practice remains largely unappreciated. This essay critically reflects on the concept of “weak theory” and examines how it can promote intellectual diversity and enhance planning practice by making theory less dogmatic and more accessible.
