In this introductory article to our PPA special issue we argue that the relation between wicked problems and collaborative governance is fraught with difficulties. Doing so, we take four steps: we maintain that wicked problems are better understood as wicked actor constellations; we delve into the collaborative governance-approach and posit that it is mainly concerned with wicked problems; we then argue that collaborative governance might not be the most feasible response to wicked problems; and after that we argue that an assumption instead of actors being engaged in actor positioning processes allows a clearer understanding of policy processes in wicked actor constellations. Following this discussion, we introduce the articles featured in the special issue and discuss implications for research.
