What are the outputs and effects of deliberative mini-publics? This is probably one of the most critical questions for any deliberative endeavor. In the realm of large-scale deliberative experiments, the G1000 in Belgium holds a special place: it happened in the wake of the longest government formation ever, it sought to gather 1000 randomly selected citizens in Brussels to discuss key social and political issues, and, above all, it was a fully citizen-led initiative. Its organizers explicitly sought to avoid any political and institutional ties and their focus was much more on guaranteeing a high representativeness and a qualitative process, rather than generating strong political outcomes. While the G1000 did well in terms of representativeness and open agenda setting, the political uptake was very limited in the short term. In the longer term, however, it seems that the effects of the G1000 were larger than initially expected. A rich set of empirical data is used to analyze the interaction between the G1000 with the entire political system by looking at the relation with the media, public opinion, political parties and MPs, and other experiments in deliberative democracy. Such endeavor sheds light on the “so what†question which is key to the development of real-world deliberative democracy.
