The lottery applied to politics refers to the random selection of ordinary citizens to participate in an assembly or panel tasked with making recommendations on a specific topic. This mechanism, used in Athenian democracy to appoint members of the Boulè, has re-emerged since the 1970s in various forms: citizen juries, conventions, deliberative commissions. Its return to public debate accompanies a growing distrust of traditional representative institutions.
Concrete functioning of citizen lottery
The principle is based on a random selection within the population, often stratified to reflect sociodemographic diversity (age, gender, place of residence, education level). The selected individuals do not apply: they are invited, and their participation remains voluntary.
Once the panel is formed, participants undergo a cycle of training and deliberation. Experts present the technical data on the topic being addressed. Citizens then debate in small groups before formulating collective recommendations.
This format differs from a referendum or opinion poll. The lottery produces informed deliberation, not a spontaneous response to a closed question. Participants have several weeks, sometimes several months, to familiarize themselves with a complex file. Documentary resources on this mechanism are compiled on sortition.net, which catalogs academic works and experiments around the world.
Citizen assemblies in France and Belgium: two distinct models
The Citizens’ Convention on Climate, launched in France in the fall of 2019, brought together 150 randomly selected citizens. Their mandate: to propose measures to reduce greenhouse gas emissions. The government committed to adopting their recommendations, either fully or via referendum.
The administrative follow-up of these proposals, documented by the Ministry of Ecological Transition, highlighted a significant gap between the recommendations made and the decisions actually adopted. The follow-up measures administrative progress, not the actual effect on emissions. This discrepancy fuels a recurring debate: a citizen assembly without binding power risks remaining consultative.
Belgium offers an interesting counterpoint, with two distinct formulas:
- In the German-speaking Community, a permanent Citizen Council chooses the topics submitted to the randomly selected assemblies and ensures the follow-up of their recommendations. This system addresses a question often overlooked: who verifies what happens to the proposals after deliberation?
- In Brussels, hybrid deliberative commissions combine randomly selected citizens and elected parliamentarians. The recommendations are then examined within the parliamentary framework, creating a direct link between citizen deliberation and the legislative process.
- These two Belgian models differ from one-off conventions by their long-term integration and their articulation with existing institutions.
Measured effects on lottery participants
A study on government citizen assemblies organized in 2024 and 2025 reports concrete effects on the randomly selected individuals. Participants show an increase in their political knowledge on the topic addressed and place greater importance on the theme after deliberation.
The study also notes a change in the relationship with institutions: participants develop an increased feeling that institutions can incorporate citizen voices. This result nuances the idea that randomly selected panels only serve to legitimize decisions already made.
These effects remain confined to the participants themselves. The question of dissemination to the rest of the population, who did not experience the deliberation, remains open. A panel of a few dozen or hundreds of people does not mechanically alter the collective perception of democracy.
Structural limits of democracy by lottery
The lottery does not eliminate asymmetries of competence. Participants arrive with very different levels of familiarity with technical files, and the quality of deliberation largely depends on the initial framing: choice of experts heard, formulation of questions, duration allocated to exchanges.
The framing of deliberation directly influences the recommendations produced. Who sets the agenda wields considerable power over the outcome. This issue, common to any form of consultation, takes on a particular dimension when participants have not chosen to be there and are discovering the topic.
The question of political accountability also arises. An elected official is held accountable in the next election. A randomly selected citizen, by definition, does not run for re-election. This absence of a renewable mandate complicates the attribution of responsibilities if a recommendation produces negative effects.
The most advanced systems, such as that of the Belgian German-speaking Community, attempt to address this issue through permanence: the Citizen Council ensures institutional continuity that one-off conventions do not guarantee. The lottery works better as a coherent complement to elective institutions rather than as a substitute. Ongoing experiments, from the Brussels model to climate assemblies, outline a space where random selection enriches democratic debate without claiming to replace it.
