The term ‘wicked problems’ is today widely used in the sustainability literature, but there is no consensus on its theoretical underpinnings or its utility for research. This paper reports on a mapping review of the wicked problems literature for which we analyzed a sample of 55 papers regarding 1. whether and how the term ‘wicked problems’ is used as a theoretical concept, 2. what meanings are associated with the concept, 3. what epistemological assumptions are stated, and 4. what rhetorical functions the concept performs. The results indicate that the concept is not always consistently applied as a theoretical concept; that authors ascribe many different meanings to the concept; that authors use diverse epistemological assumptions that are not always made explicit; and that the concept performs a wide range of rhetorical functions. The results provide a vocabulary that enables sustainability researchers to more clearly position their work in the dispersed wicked problems literature.
