New Deliberative Democracy Wave: Is Party Ideology Driving the Shift?

Global democratic innovations, particularly the rise of deliberative mini-publics (DMPs), are reshaping how public administrations engage with citizens. But new research questions the ideological forces behind this "deliberative wave."
Over the past three decades, public administrations worldwide have increasingly adopted democratic innovations to enhance citizen involvement, improve policy legitimacy, and expand the diversity of voices in decision-making. Following the global spread of Participatory Budgeting (PB) around the turn of the century, the last decade has seen the rapid diffusion of Deliberative Mini-Publics (DMPs)—procedures closely associated with the principles of deliberative democracy.
The Organization for Economic Co-operation and Development (OECD, 2020) has even identified this as an ongoing "deliberative wave," with DMPs being widely adopted, particularly across highly industrialized nations. DMPs, such as Citizen Assemblies, are seen as a powerful tool to increase responsiveness and cushion resistance to controversial policies.
The Missing Piece: The Role of Political Parties
While there is extensive research on the potential and limitations of DMPs, there is a significant gap in understanding the political actors who commission them—specifically, the influence of political party ideology. This is crucial because a party's ideology shapes its values, its interpretation of democracy, and its view on the centrality of citizen participation.
Traditional View: Left-wing parties have historically been more aligned with increasing citizen connection to political decision-making, and studies often show leftist politicians are more favorable toward deliberative procedures.
The PB Parallel: Research on Participatory Budgeting found that while the leftist ideology of the governing party was vital for its initial expansion, its influence waned over time. However, ideology continued to influence the design of PB, with left-wing commissioners tending to foster greater deliberative quality and empower participants more.
New Findings on DMPs
This new investigation dives into the OECD dataset of all known DMPs commissioned by public authorities in Europe over the last four decades to determine: Are political parties with particular ideological affiliations more involved in commissioning DMPs? And does the institutional design of DMPs vary by the governing party's ideology?
The analysis provides the first large-scale descriptive insights into this phenomenon:
Ideological Pattern of Adoption is Less Clear: Unlike the early expansion of Participatory Budgeting, the overall pattern of DMP adoption does not show a clear-cut ideological preference. The "deliberative wave" is not solely a product of left-wing advocacy.
Design Matters: A stronger ideological differentiation emerges when examining the design features of the implemented DMPs.
These results suggest that while the act of commissioning a DMP may be spreading across the political spectrum, the quality and empowering nature of the procedure itself may still be heavily influenced by the ideological leaning of the governing party. Understanding this dynamic is key to predicting the future development and ultimate impact of this major democratic innovation.
