Complexity in the law and administration of social security: is it really a problem?

This article analyses the problem of complexity in relation to the law and structure of the modern welfare (social security) system and its impact on administration, which has represented a significant driver for simplification reforms in the UK. The article outlines diverse conceptual and methodological approaches to the definition of complexity. It argues that despite the difficulties which complexity presents, attention should also be paid to the dangers of simplification and that a degree of complexity in relation to social security provision may be necessary if rights to welfare are to be adequately safeguarded.
