3.2.3. Methodology

The methodological support used in the voting experiment was the analytic hierarchy process (AHP), a multicriteria technique proposed by T.L. Saaty [53]. First, a hierarchy (Figure 5) that contains the relevant aspects of the problem was constructed by the research team responsible for the Cadrete project. Before eliciting the citizens' preferences, a brief presentation of the AHP methodology was made to the citizens by the research team. Then, following a top-down procedure, the individuals incorporate their preferences by means of the pairwise comparisons of the elements considered, following Saaty's fundamental scale (Table 2). Finally, the methodology aggregates the values throughout the hierarchy to obtain the total priority of each alternative with respect to the objective of the problem [54].
