Abstract: | Public officials can be reluctant to use citizens’ input in decision-making, especially when turnout is low and participants are unrepresentative of the wider population. Using Fritz Scharpf's democratic legitimacy approach, the authors conducted a survey-based vignette experiment to examine how the input legitimacy of participatory processes affects (1) public officials’ willingness to use public participation in administrative decision-making, (2) their assessment of the quality of the policy decision, and (3) their anticipation of popular support for the policy outcome. The study shows that turnout and participants’ representativeness have a positive and significant effect on public officials’ attitudes toward public participation. Specifically, participants’ representativeness influences public officials’ willingness to use citizens’ inputs more than turnout. |
