This chapter problematises the introduction of the concept of the ‘wicked’ problem, derived from (Rittel and Webber, 1973)), into the inclusion-related literature. The chapter outlines some key features of (Rittel and Webber, 1973)) proposed distinction between ‘wicked’ and ‘tame’ problems, and interrogates their arguments from a poststructuralist perspective. An alternative ontology derived primarily from Deleuze (2004) will be considered, which recognises the potential complexity of problems while avoiding suggestions of intractability that risk undermining resistance to the problems of in/exclusion and structural inequities.
