“…Elicitation of preferences in policymaking requires that there exists a basis for decision, typically in the form of more or less objective so-called impact assessment reports describing the impact of different alternatives on objectives but strive to be neutral with respect to decision maker preferences. The impact assessment approaches can be more or less formalized, and examples used together with decision analysis approaches within the context of policymaking published in the literature include, for example, life-cycle assessment (Miettinen & Hämäläinen, 1997), quality-adjusted life years (Drake, Kulkarni, & Kestle, 2009, Kivunike, Ekenberg, Danielson, & Tusubira, 2014, life microlevel simulation and system dynamics (Gou et al, 2001;Hansson, Danielson, & Ekenberg, 2008), scenario planning (Montibeller, Gummer, & Tumidei, 2006), and causal map problem structuring methods (Comes, Hiete, Wijngaards, & Schultmann, 2011;Larsson & Ibrahim, 2015) modelling cause-effect relationships.…”
