This paper focuses on the potential role of reflection and double loop learning in policy analysis and shared community learning. The discussion is illustrated by the case of HS2, a proposed high-speed railway project in England. It is noted that the foundation of social learning models is a rejection of traditional reliance on technologies or market forces in order to solve societal problems. Citing scholars in this field, the notion of transformative learning is introduced. This describes a process where people gradually change their views on the world and themselves in response to an external "trigger", A tool to facilitate transformative learning is double loop learning.
