| Summary: | The aim of this chapter is to use both philosophical analysis and empirical evidence to map the way in which claims of need feature in our thinking about distributive justice. The first question is whether a clear line can be drawn between needs and other demands that can be described as interests or preferences, and if so how? Where needs can be identified, what role do they play in decisions over resource allocation? In particular, does justice require that those whose needs are greatest should always have first claim on the resources available, or should resources be distributed more widely and evenly, for example in proportion to relative degrees of need? Might there even be cases in which triage is considered to be a just practice, with priority given to those whose needs can be fulfilled with least expenditure of resources? What difference, if any, does it make if recipients are responsible for having unsatisfied needs as a result of their past behaviour? Does this diminish their claim to be helped, or maybe eliminate it entirely? By reviewing experimental and other work on relevant aspects of justice, the author explores how far philosophical theories of needs-based justice capture the role that needs play in lay thinking about just distribution.
