The focus of this article is the development of neighborhood planning in England, in particular its guiding principle of local people as rational actors. The article looks at neighborhood planning in its own terms; that is, it looks at the rationality of engagement in a new system that seeks to tip the balance of rationality in favor of communities following the UK government’s aims of overcoming local resistance to the development of new housing. While there is evidence that neighborhood planning is enjoying some success, this is a delicate settlement.
