1. General Introduction

As the global community confronts the multifaceted challenges of climate change, the need for innovative and inclusive decision-making becomes ever more pressing. Within the ambit of the CLIMAS Horizon project, this methodological guide offers a comprehensive approach to setting up and facilitating Climate Assemblies. Our primary contribution lies in shifting the focus from broad issues to specific policy dilemmas in a more balanced process. By doing so, we aim to foster deliberations that are both deeper and more targeted, ensuring they are rooted in a value-based approach. This guide provides a detailed framework on how to design all the assembly phases to achieve this specific deliberative focus, ensuring that participants’ contributions can have a meaningful impact on climate action. Before delving deeper, one might ask: What exactly is a Climate Assembly? Why is it deemed valuable, and how can its effectiveness be enhanced?

1.1. What is a Climate Citizens’ Assembly?

Citizens' assemblies are an attempt to involve everyday people in political decision-making and are one of the most popular practical expressions of deliberative democracy today.1 Deliberative democracy is an inclusive form of governance in which decision-making is achieved through discussion and dialogue, with the aim of developing and moving individual preferences towards a collective agreement (Dryzek, 2001, p. 1). Climate Assemblies are therefore an attempt to address the challenge of climate change using a deliberative democracy approach.

Citizens’ Assemblies bring together a group of individuals, recruited through random and stratified selection to broadly reflect the wider population with respect to key demographics. The assembly deliberates on the basis of the value-based and experiential knowledge of the participants and the information provided by different perspectives from knowledge holders, which leads to the production of a set of recommendations with the aim to inform decision making.

1.2. Why a Climate Assembly?

Climate Assemblies are a response to a double crisis: On the one hand the crisis of Western democracy and classical political representation, and on the other hand the climate crisis. Some civil society groups, experts, and political leaders argue that short election cycles do not allow political representatives to address the long-term challenge of climate change.3 In contrast, a group of citizens selected by lottery could approach it with intrinsic surplus value by creating a strong social mandate, focusing on long-term solutions, co-designing actionable plans, building public trust, and ensuring social justice through a socially-inclusive approach (Howarth et al., 2020, p. 1112-1113). In this spirit, and building, in particular, on the experience of the Irish Citizens' Assembly, the Extinction Rebellion movement in the UK and around the world began to call for the use of Citizens' Assemblies to politically address climate change, thus increasing the demand for these assembly formats. The European Climate Foundation and many governments have also stepped up to the plate, and have promoted and financed the implementation of various climate assemblies across Europe. In reality, both public bodies and civil society institutions have established climate assemblies at different levels of governance, triggered by a variety of factors (KNOCA, 2022) and with a variety of outcomes.

1.3. How to improve Climate Assemblies?

Climate Assemblies have become a revitalising force for climate action and democratic innovation at the local, national, and global level. However, it is not entirely clear what the real impact of their recommendations on public policy has been (Thorman & Capstick, 2022). Are the recommendations lacking in specificity or depth? Do governments base their acceptance or rejection of recommendations depending on their own agendas? Do the benefits of implementing the recommendations take account of the associated trade-offs? Do they lack adequate technical detail? Is the assembly perceived as being monopolised by a particular political group or section of society, thereby generating suspicion among other groups? The methodology presented here is an attempt to address some of the problems related to these questions through a practical and specific approach.

First, we believe that a problem that cuts across the vast majority of Climate Assemblies is related to the fact that climate change is not one single issue, but is composed of multiple issues. Mitigating and adapting to climate change will require society to make significant changes to the socio-economic system on which it is based. It is necessary to change the way we live, eat, move, use energy, etc. In this context, an assembly process with a limited duration may not have the necessary bandwidth to delve into such complexity with the required depth.

Second, what does it mean to discuss an issue in depth? As we will see in the following chapters, our assumption is that the most effective way for citizens to delve deeper into an issue or topic is to focus on the policy or value-based dilemmas associated with it.

1.4. The Keys to The Methodology

This methodology guide is based on the hypothesis that the potential impact of Climate Assemblies' recommendations on public policy could be significantly increased by improving the design of the assembly process itself, including both agenda setting and follow-up. Building on the OECD's good practice principles for deliberative processes (OECD, 2020, p. 130-147),8 this guide seeks to develop the principle of integrity through the concept of balance and the principle of purpose through the policy dilemma approach. It also proposes that assemblies should be permanently institutionalised to tackle the long-term challenges of climate change by breaking them down into manageable tasks.

1.4.1. Balanced Diversity

In discussions around the management and coordination of Citizens’ Assemblies, 'independence' and 'neutrality' are often emphasised.9 While independence remains important and will be highlighted in chapter 3, especially regarding the role of an independent organisation experienced in delivering such processes, it is not the sole factor to consider. The commissioners who activate the assembly inherently have political affiliations. This makes it difficult to abstain from influencing key aspects of the assembly’s design.10 They cannot merely entrust the neutrality of the process to contracted managers or operators with a clientelist relationship. Moreover, the pretence of neutrality can inadvertently strip the process of its democratic essence by removing conflicts and debates.11 In contrast, this guide elevates 'balance' as the main core aspect, applied to the governance of the process, the content provision, and the body of participating citizens. We propose this shift towards balance as a more tangible and actionable principle.

Achieving balance in governance could be contemplated through the inclusion of stakeholders, which would ostensibly enrich the process with a variety of perspectives and values. However, there are challenges to this approach. Direct stakeholder involvement without a clear objective framework could introduce bias and undermine the perceived legitimacy of the assembly. This leads to the pivotal question of who decides how and to what extent stakeholder perspectives should be taken into account.

In practice, this methodology proposes political parties as the above-mentioned objective framework that can be seen as legitimate by the general public and interest groups. The diversity of values held by different parties serves as a good enough proxy for the distribution of values in society, allowing a wider range of stakeholder perspectives to be mapped. Consequently, the basis of process balance is achieved through the formation of a broad oversight group that includes representatives of all political parties, reflecting the composition of Parliament, with party representation based on the number of seats they hold. The oversight group, once constituted, nominates experts representing different stakeholders perspectives relevant to the political dilemma at hand. Ideally, this list of experts should be approved by randomly selected citizens.12 The content group will be entrusted with curating a tapestry of information that is as rich and multifaceted as the societal debate itself. By weaving together these varied strands of perspectives, the content provided to the Assembly will embody the balance we seek, with the selection of experts being a transparent process that enhances the group’s legitimacy and the Assembly’s integrity.

Similarly, for the body of participating citizens, balance is operationalized through a combination of random selection and careful stratification. Existing academic attitude surveys serve as a foundational element in this process, providing an additional criteria regarding the policy dilemma under consideration. The assembly thus becomes a microcosm of society, both in demographic composition and in the diversity of perspectives, achieving a nuanced form of balance.

By seeking balance in these specific ways, this guide offers a pragmatic and democratic blueprint for setting up and facilitating citizens' assemblies. This approach embraces the complexities and diversities inherent in society across all phases of the assembly.

1.4.2. From Issues or Topics to Policy Dilemmas

Focusing the deliberation on a topic or issue in isolation presents two distinct but related challenges. The first is the risk of falling into an ‘epistemic trap’.13 In this scenario, discussions veer toward technical nuances and evidence-based solutions, leaving little to no space to consider the valuebased trade-offs that are often the cornerstone of political debates. This focus on technicalities may set citizens up for a task that is typically the domain of experts, which may lead to frustration and missed opportunities for meaningful citizen deliberation.

The second challenge arises when generic questions are posed for deliberation. These questions often result in wish lists14 that overlap with existing or planned policies, making it challenging for citizens to distinguish any new contributions. This is exacerbated by the fact that complexities of policy nuances are not easily grasped. Like the epistemic trap, this approach also lacks the time or space for considering the value-based trade-offs involved, which could be a basis for rejecting these proposals.

In short, the topic-based approach may lead to either overly technical discussions or overly broad wish lists, both of which lack the potential for significant policy impact. The key contribution of randomly selected citizens in the deliberations does not arise from their individual expertise or competences, but rather from their diverse value-based perspectives15 and collective ability to reach agreement on policy issues. Thus, the objective should not be to turn lay citizens into experts, which will not happen in the limited time available for deliberation. Instead, the focus should be on creating a setting where their diverse perspectives are guided by a value-based approach, offering a pathway to navigate through the complexities of a political dilemma while minimising the technical aspects. This dilemma approach to deliberation will also help to keep a balanced perspective throughout the process.

1.4.3. Tackling Manageable Tasks in a Permanent Process

To avoid the creation of wish lists, it is important that the task of the Assembly is both specific and manageable, not made up of multiple dilemmas. Addressing the issues in depth sidesteps recommendations that may not be actionable, thereby making a meaningful difference to other political processes. In this way, it is proposed to break down the challenges of climate change into parts and avoid treating the issue in a generic way. Not all countries or regions face the same challenges. While some countries have a lot of solar radiation, others have a lot of wind. While in some countries the main threat is drought, in others it is flooding. This approach allows different regions to focus on different dilemmas and not replicate the same processes, complementing and enriching a global and more coherent deliberation with many assemblies in different places focusing on different challenges. There is no need for a region with a similar dilemma and social reality to replicate the same process, it can simply address a new mandate and learn from the recommendations of previous assemblies in neighbouring cities, regions, or countries.

With this in mind, we propose a continuous process to address each issue in a differentiated manner. Because of the climate emergency, some people might think that societies should address all issues as soon as possible. In practice, given the limited resources available for holding citizens' assemblies, the frequency of repetition of each deliberative process for each theme could vary according to the challenges of each place. This pragmatic approach will allow our societies to adapt and address the most relevant and urgent challenges at any given time with Assemblies, while dealing with the rest through classical decision-making processes.

1.5. How Do We Create This Methodology?

The initial draft of our methodology is based on our experience as mini-public practitioners. The experience of Deliberativa, the partner leading this guide, draws on local processes such as the Barcelona Youth Forum or the Madrid City Observatory, regional processes such as the Besaya Citizens' Jury, the Valencia Mental Health Assembly or the Gipuzkoa Climate Assembly, global processes such as the Global Assembly on Climate Emergency and European processes such as the Conference on the Future of Europe or the Citizens' Panels of the European Commission, the latter shared with another organisation of the consortium: Ifok. This second Ifok partner also has extensive experience in Germany in local, regional and national processes and is continuously contributing to the revision and improvement of the methodology.

The initial draft of the methodology aims to be implemented in the three processes led by the different partners of the consortium: The Generalitat de Catalunya leading the Catalan Climate Change Assembly, Green Liberty leading the Riga Assembly and Ifok leading the Edermunde Climate Assembly. In all these processes, Deliberativa will play a supporting role, with particular attention to the Catalan Assembly.

It is important to recognise that this methodology is very detailed and exhaustive and its implementation will depend on the political will and resources available in each scenario.

While the main driver of the methodology, the dilemma-based approach, will cut across all three cases, we expect that not all other elements of the methodology can be developed in the same way. In a distributed manner, more specific aspects of the methodology may be tested in one assembly but perhaps not in the other, and vice versa. The aim of these tests will be to calibrate the initial proposal in a kind of virtuous circle in order to generate a final proposal in 2025.

In addition, other climate or similar assemblies in which Deliberativa and Ifok are involved during these years will also serve to test and develop different parts of the methodology. In 2023 this will be the case of the design of the Permanent Assembly of the Basque Country, which Deliberativa is developing together with other actors and the Basque Government, or the National Citizens' Assembly on Nutrition in the German Bundestag, led by Ifok and other external partners to the consortium. Both cases will be informally added as learning cases that will also feed into this guide.

By 2024, it is possible that the Climate Assembly of the island of La Palma will also join the series of experiences.



2. Political and Budgetary Feasibility

Any Citizens’ Assembly that aspires to a strong follow-up in policy-making needs to be established by the appropriate authority, i.e. a public decision-making power. Ideally, in order to maximise the impact of the assembly, this public authority, institution, or organisation, hereinafter the commissioner,16should be the one to establish the assembly process.

Establishing such an assembly requires a major commitment. The aim of this chapter is to understand the extent of this commitment and to help the commissioner decide whether it is feasible to activate the Citizens' Assembly process.

Firstly, we consider the question of permanence, followed by the political feasibility assessment, addressing not only the commitment to the outcome in the form of citizens’ recommendations, but also the role assigned to the commissioner, who will have an important voice in the process but will not control it. We then consider the question of budget feasibility: The commissioner needs to be aware of the scale of the effort, both in terms of external work packages to be contracted and internal services to be taken on. It is the commissioner who has to take responsibility for putting in place the resources, both financial and human, to enable the assembly to take place. Finally, we consider the possibility of activating an assembly that is not established by a public decision-making body.

2.1. Assessing Permanence

We noted in the previous chapter that making assemblies permanent is a key aspect of the innovation proposed in this guide. Thinking about permanence from the outset will be very useful for any commissioner who has led Citizens' Assembly projects in the past or who is very clear about what they want. For a commissioner who is approaching a Citizens' Assembly process for the first time and is not yet clear about how it works and what is wanted, a more pragmatic approach would be to treat the first assembly cycle as a pilot. In the latter case, a pilot assembly provides an opportunity to understand the mechanics and benefits of a Citizens' Assembly. Once the pilot is complete, the commissioner can evaluate it and decide whether to set up a permanent structure to look at other issues.

While this guide places emphasis on the establishment of a permanent process, it is equally equipped to guide those considering a one-time assembly or pilot assembly. Commissioners can effectively utilise the principles and guidelines presented here without the commitment to permanence.

2.2. Political Feasibility Assessment

In the absence of specific ad hoc legislation, the proposals and final decisions of the Citizens' Assembly will be called 'recommendations' and will not be binding. The commissioner will have the final say. However, the commissioner might want to consider that part of the decision-making power is delegated to the citizens participating in the assembly. Thinking and acting as if the process was binding, even if it is not and is based on the political commitment of the elected official, will help to make it more rigorous and effective. In this way we can define the first commitments to be made:

  • At the end of the process, the members of the assembly will recommend what measures or legislation should be implemented to tackle the policy dilemma. It must be also assumed that, as a commissioner, it will be its duty to do all it can to implement these recommendations and, if it does not, to explain why.

Accepting the importance of these recommendations entails concern about how citizens arrive at them and how their implementation is followed up. The function of overseeing the good execution of the process implies accepting the governance of it.

  • The process will be governed by giving centrality to a group of citizens who will participate in a Citizens' Council.17 This council, being deliberative in nature, will consist of citizens chosen through a democratic lottery and its members will rotate periodically. Its role will be to set the agenda and oversee the functioning of the Assembly, as opposed to the role of the Citizens' Assembly,18 which will deal with a specific policy dilemma. This citizen body will work closely with the oversight group, which will prepare, together with the project team, the information and facilitation for the decision making of this body. These key actors are defined in the next chapter.

In practice, setting up a Citizens' Council means running two citizens' bodies in parallel.19 Given the leap in complexity and cost this entails, we consider it wise to activate this second body after the first assembly pilot, once the commissioner has taken the step towards permanence.

The oversight body will be able to take final decisions provisionally until the Council is established.

As a consequence of this last commitment, the commissioner must accept that they will not have direct guidance over the assembly process. Instead, they will be part of a larger balanced group, from now on the oversight group, that will help to inform and oversee the work of the Citizens' Council and the project team to maintain balance. This includes the agenda setting that will define the policy dilemma that will create the mandate for the Citizens’ Assembly.

2.3. Budget Feasibility Assessment

A commissioner approaching the idea of a Citizens' Assembly for the first time is usually inclined to underestimate the scale of the project. It is therefore very important to understand beforehand the costs and the commitment of human resources required by their own administration in order to be able to assess its feasibility.

Here are some outlines to understand the scale of the effort for the first Assembly cycle, excluding the Council. This will be a 12-18 month single cycle process involving a dedicated project team of 23 people working almost full-time. Another team of about 6-8 people will work part-time, coordinated by the project team, and a large team of staff will be mobilised for the Assembly sessions, which could involve more than 30 people. Between 24 and 100 citizens will need to be informed, facilitated, fed, and accommodated during the Assembly sessions. Assembly working time is crucial: Whereas a minimum of 30-40 hours20 is usually recommended for generalist assemblies, the dilemma-based method proposed here requires around 55 hours.21 These hours are spread over about 4 to 6 weekends during 3 to 4 months.

Figure 1 shows a tree map of the different budget packages for a 55 hour assembly with 100 members. The core players are the team working throughout the year. The work of the operators will be more concentrated during the Assembly events. Logistics includes all costs related to the organisation of session events: Venues, catering, travel, accommodation, internet, sound equipment, projectors, screens, materials, etc. Facilitation includes the people who present, moderate, and facilitate the citizens' work. Recruitment includes sorting, contacting by letter and telephone, stipends for citizens, stratification and management of citizens. The project team coordinates all the work and supports the oversight and the content group. The content group prepares the content to be shared with citizens for informed and balanced deliberation. The communication team is responsible for communicating the process to the wider public.

Figure 1 - Permanent Citizens’ Assembly Budget 

We will consider two cost scenarios, the local one, where it is not necessary to pay for long travel and accommodation for participants, and the non-local one, where it is necessary to include these costs. Figures 2 and 3 show some estimates for monolingual meetings with 55 hours of deliberation:

Figure 2 - Estimates for 55 Hours of Deliberation in Non-Local Assembly

Figure 3 - Estimates for 55 Hours of Deliberation in Local Assembly

2.3.1. Size of the Assembly

An assembly typically ranges from a minimum of 24 to 32 members to as many as 200 members with sufficient resources. It is an attempt to represent22 As with any representative sample, the larger the sample, the more representative it will be. Ideally, larger assemblies could be held to improve representativeness, but the reality is that as the number of participants increases, the complexity and cost of the process increases strikingly. In figure 4 we show how the budget increases exponentially with the number of participants:

Figure 4 - Exponential Budget Increase Relative to Participant Numbers

This non-linear increase in the budget is due to the growing complexity of the event sessions, while the budget of the core players remains largely unchanged.

The budget of the core players and the number of hours of assembly work, which are crucial for the quality of the process, should not be limited by the ambition to have a very large assembly. A small assembly guarantees a simpler process in which its deliberations can be more in-depth and agreements can be more effective, compensating for the less representative nature of the sample. In practice, we are looking for a reflection of the demographics of the population, which can actually have political representativeness, not a statistical one.

2.3.2. Are Costs Reduced by Internalising Services?

It is possible to find specialised staff within the administration, or even use existing framework contracts to internalise costs. It is important to identify these services or staff and engage them at the right time. This strategy can reduce direct costs by around 25%. See figures 5, 6, and 7 for details.

If training of administrative staff is required, it is important to remember that this will always be more expensive as it requires the time of external consultants. However, this will lead to mediumterm savings on similar projects in the future. Commissioners intending to institutionalise23 deliberative practices should engage in progressive training of their staff.

Figure 5 - The Path towards Institutionalisation

Figure 6 - Budget Estimation for Local Assembly with 25% Indirect Costs Reduction

Figure 7 - Cost Reduction Strategies in Administration and Their Impact

2.3.3. Feasibility of a Permanent Assembly Budget

Those commissioners who are willing and motivated to make the process permanent should also assess the feasibility of a permanent budget flow, which will inevitably be required. The costs should cover one assembly for each cycle of deliberation. Each assembly will have different citizen participants and address different dilemmas.

The Citizens’ Council should become active in a permanent process. This second body could increase the cost of each cycle by 10-20% due to the events of the Council, with a minimum of 24 persons, as shown in figure 9.

Figure 8 - Budget for Permanent Citizens' Assembly with Council Involvement

Figure 9 - Budget Estimates for Non-Local Assembly and Council Involvement

Each cycle, the commissioner will be able to internalise, systematise, and streamline implementation. In short, the cost of the process will be significantly reduced within a few years. Although there is not much experience of institutionalisation, the experts who have contributed to this guide suggest that after a few cycles, costs could be reduced and internalised, cutting out-ofpocket expenditure by around 25 to 35%. Another way to reduce costs could be to repeat cycles less frequently, for example twice a year instead of annually.

2.3.4. Navigating Financial Constraints

These budgets are based on experience in European countries and are indicative. For those local authorities who are looking for the cheapest price and still find that the figures are out of their budget: It is important to understand that the design should not go below 55 hours and 24 citizen members, and that all packages are essential for a quality deliberation. It is still possible to get the project off the ground if the commissioner has motivated and available staff. When we explore possible strategies to meet this challenge, several key approaches stand out:

  • Shift to indirect costs: The commissioner will need to strengthen its internal team or make better use of existing supplier contracts. The costs will not disappear but making them indirect can facilitate the internal justification of the project.
  • Seek external funding: Consider the possibility of obtaining funding from organisations that are willing to support the initiative without directly influencing its course.
  • Form strategic collaborations: Partnering with institutions such as universities can be beneficial. For example, a scholar could take on the role of 'evaluator' as part of their academic journey.
  • Engage volunteers, interns and experts: Harnessing the enthusiasm of volunteers, students, or experts who are passionate about the subject can be a cost-effective way to strengthen the team. Local government or educational institutions may have resources or programmes to facilitate this strategy.

By adopting these approaches and with a proactive leadership of the project team, commissioners could more effectively address the financial challenges.

2.4. An Assembly that is Not Established by a Public Decision-Making Body?

Although not common, there are cases of assemblies that are not activated by a commissioner. It could be a community, a university, a private foundation, or any other body that has no decisionmaking power over the public sector. It is always possible to activate an Assembly in this way, however, as has been seen, it is often the case that such processes have great difficulty in passing on their recommendations to a commissioner. Budgetary feasibility can be assessed in the same way as if one were a commissioner, but this is not the case for political feasibility.

First of all, the most advisable strategy is to convince a commissioner to hold the Assembly. If funds are available, it is more likely that a commissioner will be able to accept the political commitment.

In this case, this methodology will be followed and the organisation that has convinced a commissioner will have to provide funding without seeking to influence the process. Providing funds should not imply becoming the project team of the Assembly, although this decision could be taken by the oversight group if it considers that it has the independence and professional experience to do so.

If a commissioner does not agree to hold the Assembly, it may still be interesting to run the process in such a way that both the commissioner and other political parties can participate informally or as observers. The Assembly becomes a living example that can help political forces gain confidence in these deliberative processes and consider establishing their own assembly in the future. In this case, the organisation activating the process should behave like a commissioner in providing funds, but should not have a seat on the oversight group, which should be given equally to the different political parties or, failing that, to like-minded stakeholders nominated by them.

Past cases show that even when the Assembly is held by a commissioner, it is difficult to achieve adequate impact of the recommendations.27 It is possible that a well-designed process, following a good methodology, can have more impact than a poorly designed Assembly held by a commissioner.28 If stakeholders and public opinion perceive the process as legitimate and intelligent, there is nothing to stop the recommendations being implemented. Thus, an Assembly, ‘from the outside’, can also serve to show how best to use or design these kinds of processes.

3. Activating Core Players

Once the commissioner has secured the political and budgetary commitment, it is time to activate the project. In this chapter, we explain how to set up the core players who will be responsible for running a fair and balanced assembly process.

As a first step, it is essential to have an oversight group with sufficient political balanced diversity. This group will need to approve the selection of the evaluator, the project team,29 and the content experts. It will also help the Citizens’ Council to set the agenda by identifying policy dilemmas to be worked on. Once the project team has been recruited, it will be responsible for facilitating the work of the oversight group. The project team can also start to define the tender for the operator(s). The evaluator will start to monitor the process at the same time as the project team is activated. The evaluator will start to monitor the process at the same time as the project team is activated. Figure 10 shows the relationship between the working groups, figure 11 shows the relationship of these groups to the citizen bodies and figure 12 shows the temporal order of activation of the different groups and bodies.

Figure 10 - Core Players and Working Group Relationships11

Figure 12 - Core Players and Working Group Relationships

3.1. Setting Up a Balanced Governance

As mentioned in the opening chapter, the commissioner must establish a balanced oversight group that will help to steer the process. This implies the inclusion of other political actors, particularly the main parties, but ideally all parties with parliamentary representation. This step is essential in this methodology, as the lack of agreement between the different stakeholders will be the lever that helps to identify the main dilemmas. In addition, addressing such dilemmas involves long and medium term policies and it will be crucial that changing parties in power are involved and committed to the process to ensure that citizens' recommendations are implemented.

The oversight group could be informed by advisors representing different stakeholders from institutions, civil society organisations, business, or academia. These experts can provide insight into the range of potential dilemmas and issues involved. The weight of these advisors will always be proportional to the party that includes them and the party may even delegate its participation in the group to this person. The people in this group may change if the parties so decide, as long as this does not interfere with the working schedule.

The main responsibilities of the oversight group are related to all major decisions that require balance and independence. In order to avoid deadlocks, broad majority decisions of 80% can be accepted for which parties have a weight proportional to their parliamentary representation. Validating the project team. The project team, both its in-house members and external experts, must be trusted by all parties for their track record and professionalism.

  •  Validating the process evaluator. The evaluator will be the one who monitors the work of the project team and reports to the oversight group. It must be a trusted and professional agent.
  •  Helping to prioritise the dilemmas. This task will be developed in the next agenda chapter.
  • Helping to select the content group. Content strongly influences citizens when it comes to positioning themselves. It must be carefully balanced. This task will be developed in the chapter of content provision.
  • Validating the editor of the content group. This task will be developed in the chapter of content provision.
  • Validating the stratification, paying particular attention to the attitudinal criteria. This task will be developed in the chapter of democratic lottery.
  • Collaborating with the commissioner to identify the appropriate government departments to receive the recommendations of the citizens’ assembly and setting a timetable for their implementation.
  • Ensuring the progress and effectiveness of the implementation of citizens' recommendations. Political diversity will allow the oversight group to be critical of the rejection, delay, or modification of the original recommendations.

In this chapter, we will introduce tasks one and two leaving the rest for later chapters.

3.1.1. Permanent Citizens’ Council

As described in the previous chapter, it is advisable to set up a Citizens' Council, which could take over, validate, and make final decisions on some of the tasks of the oversight group.

Figure 13 - Cycles of the Permanent Citizens Council

3.2. Selecting the Project Team

Who will lead and coordinate the deliberation? This is a very sensitive issue as there are many small coordination decisions that will affect the process. Therefore, the oversight group should validate32 the selection of an experienced and independent organisation that inspires confidence in its ability to run a fair and balanced deliberative process33 that meets international quality standards. As these processes are lengthy and time-consuming, it is important that this organisation or experts are adequately resourced and have sufficient time to devote to the project, which will last at least one year.

The project team should also include in-house experts representing the commissioner. They should be officials who understand this kind of process, who have sufficient authority within the government and who are also trusted by the opposition parties because of their professionalism; there may be an area of open government or citizen participation and that is where this profile could be found.


Figure 14 - Composition of the Project Team

The constitution of this group is a meta-decision, i.e. it has to be taken as soon as possible since the incorporation of this group is crucial for the very facilitation of the oversight group itself.34 Once the project team is active, it should start organising the tender process for the operator(s), starting with the communications team. The operator(s) should also provide the citizen lottery service, logistics and facilitation. For reasons of simplicity, it is recommended to minimise the number of tenders and to encourage competitors to form consortia. Once the operator(s) have been selected, a member of their team could be included in the project team.

3.2.1. Selecting the Communications Team

The communications team will be a strategic member of the project team throughout the process and will require a specialised organisation, so it is usually recommended that they be included in a separate tender. They will ensure the transparency of the process by communicating each step of each phase to the public. They will also be responsible for a strategy to extend the deliberation to the general public. The aim of communication will therefore be not only to increase the visibility and impact of the whole assembly process, but also to translate the reflections, conflicts and agreements that take place in both the preparatory and assembly meetings.

The communications team needs a senior strategic public communications lead, supported by a team of multimodal documenters and creatives. A specific procurement process may be required.

3.2.2. Selecting Other Operators

Operators require a specific procurement. Depending on the ecosystem of providers in the region, different work packages could be split or merged to ensure that a minimum number of providers or consortia can present their proposals. If the project team has sufficient expertise or can recruit another organisation of advisory experts, it could activate the project without the operators. If the operator or one of the operators is needed in the project team from the beginning, the activation of the project could be delayed until the main operator is contracted.

3.3. Selecting the Evaluator

The evaluator should be an organisation or individual with experience in deliberative processes.35 Ultimately, it will depend on the oversight group, which will also be responsible for its selection. This is crucial because the evaluator, like the project team, should be independent of both the commissioner and the project team. It should have access to all working meetings from the beginning of the process, including meetings of the oversight group itself. This is also a metadecision, like that of the project team, and should be taken as soon as possible.

The ultimate goal of the evaluation is to improve deliberative assemblies, so the evaluator's work should be proactive, not just critical. He/she should work together with the project team. If they have doubts about any aspect of the design, they should discuss it with the project team to try to avoid methodological errors. If problems still occur, the evaluator must interpret why they occur and suggest how to avoid them. The evaluator may disagree with the project team, in which case the data and arguments should be presented and the project team should be given the opportunity to attach a note prior to publication of the final report. If the problem is critical and relates to a failure of standard good practice or an imbalance in the process, and the project team does not correct the problem, the evaluator may report to the oversight group, which may intervene. The project team should thus have access to the draft evaluation, which it may discuss or annotate.

4.  Agenda Setting  

This chapter introduces the agenda-setting process. To understand this key task, we explore the concept of policy dilemmas and their role in citizens' assemblies. The complexity of dilemmas is explored using the example of climate change. Understanding the importance of aligning these dilemmas with the policy agenda, it discusses how to select dilemmas in such a way as to ensure that the dilemmas selected are impactful and relevant.

4.1. Policy Dilemmas

The population over which the commissioner has jurisdiction faces different challenges; there are different views on which of these challenges are most relevant. A variety of political parties, stakeholders, and experts will prioritise these challenges differently. Many citizens also have something to say about these issues. How does the Citizens’ Council, helped by the oversight group and the project team, frame the process by choosing the right policy dilemma for the Climate Assembly? But first, what exactly do we mean by a policy dilemma?

The democratic framework, and to a greater extent the framework of deliberative democracy, assumes citizens have the capacity to participate in political decisions. The usual critique of democracy from an elitist perspective argues that the issues of governance are too complex for the people to make good decisions (Jacquet, Niessen & Reuchamps, 2022, p. 297). While we will not enter into this debate in this methodological guide, we do acknowledge that political decisions usually require a certain degree of specialised or technical knowledge (Leino et al., 2022, p. 429). However, given their role in regulating the function of society, it is worth considering that such decisions inherently incorporate a subjective element that is connected to people’s values and interests.

Figure 15 - Political Decision

The conventional method of framing political issues often sets the stage for either an ‘epistemic trap’ or the creation of generic ‘wish lists’. For example, if we start by saying "How do you solve X?" we presume that X must be solved and the challenge can be quite technical. Questions such as "How do we reduce food waste?" or "How do we reduce greenhouse emissions?" make it probable that citizens will agree on the need for a solution. However, the lack of a clear understanding of how to address these issues, or the awareness of obvious and simplistic solutions, leads Citizens' Assemblies to become venues primarily focused on listening to experts. In these settings, the emphasis is on understanding and prioritising expert proposals, without a comprehensive grasp of the value-based trade-offs involved. In the end, the government receives a list of good ideas that it already knows and that are less specific and coherent than they would have been if they had been drafted by a group of experts. Many of the Citizens' Assemblies have tackled an issue or problem in this way.

Our aim is to design a process with a values-based mandate rather than a technical one. Such a mandate will reduce reliance on specialised knowledge and increase reliance on value- related knowledge, which is already part of everyone's cognitive backpack. It will increase the capacity of citizens to work, the added value they can bring and the impact of their contribution. A policy dilemma is a value-based problem for which there is no clear or simple answer. But how can we identify such a policy dilemma in practice?

There is a useful approach that answers this question: What aspects of the policy issue do experts representing different stakeholders disagree over? In answering this question we must avoid technical approaches; it is not a question of deciding what kind of technique will solve something, but of identifying what value issue the experts disagree on. For example, there are doctors who believe that euthanasia should not be used and others who believe that it should be used in certain cases. These preferences are not related to their speciality or level of expertise, but to their own values and beliefs.

Good examples of policy dilemmas are: "Should euthanasia be allowed, and to what extent?" or "To what extent should we allow abortion?” The challenge here for a Citizens' Assembly faced with such a task will be to strike a balance in a situation involving trade-offs based largely on their values. While some technical information may be needed to support the deliberation, the core of the exercise is now value-based. The recommendations will be a short, balanced agreement on how to proceed, something that neither the experts nor the different political parties or interest groups can legitimately or practically come up with.41 Citizens are involved in catalysing social agreement.

We started with these examples, even though they are not related to climate change, because they are easy to understand. The problem is that it is not always so clear what the policy dilemma is on any given issue. Identifying a dilemma often resists easy analysis and may remain invisible, especially in contexts of uncertainty and fragmented information (Janin, Acloque & El Nour, 2023, p. 337). In these cases, it is necessary to work together with experts in the field to understand where the dilemma lies.

4.1.1. Policy Dilemmas in the Context of Climate Change

When we start to break down the challenge of climate change, we realise that it touches almost every sector of our economy, politics, and society as a whole. Tackling climate change means transforming our societies across the board. In terms of mitigation alone, we have issues such as: energy, transport of people and goods, the food cycle, construction and housing, and many more. If we add adaptation, we have: Drought, floods, high temperatures, migration, ecosystem adaptation, primary sector adaptation, etc. With such a variety of issues, it is conceivable that each may have its own particular dilemmas, such as abortion or euthanasia, which are different in nature.

However, there is an overarching pattern that allows us to interconnect a multitude of these issues.

To understand this pattern, let us consider an example. Anyone who cares about the environment faces a dilemma every time they go shopping. Many people know that eating less meat reduces environmental impact and emissions, as do using organic and locally produced items. They find themselves in a situation that demands a double effort: On the one hand, they have to change their habits, such as eating less meat, and on the other, they have to spend more because organic or locally produced items tend to be more expensive. Some possible questions to unfold the dilemma could be: How much effort do I need to make for the common good? Is it fair for me to make this kind of effort, given the effort others make? But it becomes even more complex when one considers that the common good is not so tangible in the short term, and for many people will not even be tangible in their lifetime.

In this way, we can divide the dilemma into two parts. It embodies the classic dichotomy of individual versus collective welfare, while also encapsulating the conflict between present and future well-being. The latter aspect can be expressed more precisely as the tension between the welfare of my generation and that of future generations. To add complexity, these dilemmas go to the edge of our moral intuition. The collective is no longer limited to a specific social group, region, or nation, but has expanded to the interconnected globality. The future is not only our children and grandchildren, but future generations – the future of humanity.

These fundamental dilemmas give rise to a number of practical dilemmas that many future Climate Assemblies will need to address. There are also some more specific ones. Let us take some additional practical examples. The installation of renewable energy requires land use, which is related to subjective values such as the appreciation of the current rural and urban landscape or the clash with other sectors of the economy (especially agriculture). Thus, a dilemma could be ‘renewable energy production vs. impact on existing land use’, and take the form of a question: How can renewable energies be deployed while maintaining a balance with the impact that their installations may have on the territory? As another example, agriculture may be responsible for a lot of emissions, but it also feeds people. To what extent are people willing to change their habits and the economies of food production in order to reduce emissions?42 Another example: How can we insulate homes on a large scale to reduce carbon emissions from heating, when not everyone can afford the cost of renovation in the short and long term, especially low-income households?

4.2. Fitting into the Political Agenda

Coming back to the questions posed in the introduction: How does the Citizens’ Council, helped by the oversight group and the project team, frame the process by choosing the right policy dilemma for the Climate Assembly? Let us now try to focus on the political problem this poses in the context of liberal democracies.

Placing the dilemma before the assembly means setting the agenda. Ultimately, setting the political agenda involves establishing the hierarchy of decisions. Prioritising issue A over B may lead to the activation of legislative processes for A, and perhaps later for B, or even result in B being forgotten. This is therefore a very sensitive phase of the process.

The political agenda is usually set by the governing party, often influenced by interest groups or public opinion. In some cases a parliamentary institution might set the agenda for a minority or coalition government. Although very rare, there are also direct and participatory democracy processes to set the agenda, for example, a citizens' initiative, which allows civil society or interest groups to collect signatures and trigger a referendum or, more relevant to our case study, a deliberative citizens’ assembly to work on agenda-setting43 which in this methodology inspires the idea behind the Citizens' Council.

It is also important to consider that within a government there may be different ministries with different agendas to push forward, and as usual, governments have limited time, resources, and political credit to make reforms. Not all ministries may be able to take major decisions; this is often carefully coordinated within the executive so as not to lose public support or to gain it, as in a game of chess.

The definition of the policy dilemma of an assembly should have an impact and fit into the overall political agenda. Otherwise it means that the political community does not expect any real decisions from the process and we may end up with fake deliberation or participatory whitewashing.

4.3. Choosing the Right Dilemma

While the final decision rests with the Citizens' Council, different political actors, both outside and inside the government, should be involved in shaping the agenda. As noted in the previous chapter, the oversight group will be helping with this task and should include a variety of political parties including the governing party, in order to bring a diversity of perspectives and broader political support to the process. This act of agenda generation is fundamental, as the political and institutional establishment delegates the political problem or dilemma to the assembly, accepting and giving it the legitimacy to deal with it.

The project team must design an appropriate dynamic to identify and prioritise dilemmas with the oversight group, encouraging informed and consensual final decisions in the Permanent Citizens’ Council. The process will consist of several sessions, sufficient to achieve a satisfactory and agreed result.

It could be the case that the dilemma has one or more defining oppositional relationships. For example: Meat consumption vs. emissions from meat production. Furthermore, the dilemma should be materialised in one or multiple questions. The answer to those questions will be the tasks of the assembly. Here are some example questions related to this scenario:

  • To what extent should we reduce meat consumption given the need to reduce emissions from meat production?
  • To what extent should individuals change their dietary habits to reduce the environmental impact of meat production? What help do they need from the institutions to make the effort to change?
  • In order to reduce greenhouse gas emissions, to what extent should governments implement policies to regulate meat production and consumption?

4.4. Agenda-Based Feasibility Assessment

It is very important to take some aspects into account when considering the possible dilemmas to be deliberated and before deciding whether the assembly should take place. It is possible that the oversight group may advise that deliberation is not feasible due to the political situation, not fitting the political agenda or not finding an appropriate dilemma. Here are some key issues to consider:

4.4.1. Scenarios for Convening a Climate Assembly

  •  There are no plans for major solutions to the dilemma.
  •  There is no majority support for the solutions on the table.
  • The commissioner does not want to bear the political cost of trying to propose a solution to the dilemma.
  •  Possible solutions imply a long-term policy, which the opposition party could reverse when the government changes. The parties that alternate in power should be committed to the Citizens' Assembly process through the oversight group and therefore to its recommendations.
  •  There is public confusion and misinformation about the dilemma.
  • All related ministries as well as the presidency of the government are aligned and committed to the assembly through the oversight group.
  • Parliament approves and supports the activation of the deliberative process.

4.4.2. Scenarios to Pause a Climate Assembly

  •  The institution has no competence to implement possible solutions.
  •   The agenda related to the dilemma is already set. Either solutions are already in place or they are already planned. The government is clear about the solution and has the time and resources to implement it.
  •  There is no time to manoeuvre in this legislature and the opposition parties are not committed to the process.
  • Elections will be held in the following 6 months.
  •  Solutions to the dilemma involve long-term policies and the alternating parties in power are not all committed to the assembly's outcome.
  • Different government ministries related to the dilemma are not aligned and committed to the assembly.
  •  The government presidency is not committed to the assembly.

Once a dilemma has been selected, the content group has to be created, this group, much more specialised in the topic, will still have room to suggest improvements in the framework and the specific question to be addressed by the Assembly.

5. ​Content Provision

As described in the previous chapter, the remit of the Citizens’ Assembly is defined by a question related to a political dilemma. The citizens' task throughout the process will be to answer this question in the form of a series of recommendations.

This deliberative process needs to be informed and all participants should receive the same basic knowledge about the dilemma and potential models or scenarios for moving forward. The content provision methodology is responsible for equipping participants with this knowledge. The content group is the team that applies the methodology in this phase.

5.1. Selecting the Content Group

The information that is presented and how it is presented is one of the critical points of a deliberative process, as it can powerfully influence the opinions of the participating citizens. Deciding who will be responsible for selecting the content is therefore a very sensitive decision. The group must have sufficient legitimacy in the eyes of public opinion and also the backing of the different interest groups affected in the process. The oversight group has the objective political diversity to tackle this task in a legitimate way. In coordination with the project team, it should make proposals to be validated and calibrated by the Citizens' Council. This will be a crucial task if there is no agreement in the oversight group.

In order to establish a balanced group of experts on the issue for content selection, the choice should not be based solely on their specific areas of expertise. It is crucial to recognise that all experts, indeed all sources (including witnesses and contributors), have a measure of bias. A highly beneficial approach is to involve experts who represent stakeholder perspectives, thereby exposing participants to a wide range of viewpoints. These could be science communicators, people from think tanks, or scientists with a strong link to practical implementation. To work toward this ideal, it is necessary to identify and map stakeholders associated with the dilemma. The primary divergent perspectives on resolving the dilemma ought to be addressed, along with an exploration of the different policy options for the government.

Our balanced governance approach allows this mapping of stakeholders and corresponding experts to be done with the help of the different political parties in the oversight group; different parties with different ideologies will target different stakeholders and different experts to represent them.

5.2. Composition of the Content Group

The content group should be composed of four distinct categories: In-house content experts, external content experts, experts on deliberation, and experts in communication. Each category has specific roles and responsibilities, as detailed below:

  •  In-house technical experts on the subject: At least one from each ministry related to the dilemma. Their responsibilities include:

 Providing information on what the government has done, is doing, or will do in relation to the issue beyond what the Assembly recommends.

Explaining the powers and limitations of the government or area/department.

Detailing the policy scope or potential impact of the recommendations.

Offering additional information related to their expertise on the issue.

  •  External experts on the topic: Approximately four to five experts covering the different stakeholder perspectives on the dilemma, including at least one or two non-specialist with a panoramic view of the issue. The external experts should:

Cover as wide a range of disciplines as possible. o Be responsible for generating content.

  • Editorial coordinator with expertise in communication/education to the general public: Selected by the project team and validated by the oversight group. He/she will be responsible for:

Executive editing, which involves translating the content proposed by experts into structured and balanced documents of the deliberative curriculum in an orderly manner and ensuring timely content production. o Curating the speaker programme with the experts. o Moderating panel discussions during the learning phase.

Ensuring the information is presented in a way that can be understood and digested by all citizen members in the time and formats available during the process.

Optionally, this role can be expanded to include a broader team including experts in communication, outreach, and educational inclusion.

  • Members of the project team. One or two deliberative experts who will:

Review the work of the editorial coordinator with content experts to guarantee transparency and balance.

In case of conflicts, decisions within the group will be facilitated by deliberative experts, striving at all times to reach consensual decisions. If consensus cannot be reached, balanced proposals will be made in which different perspectives are presented.

5.2.1. How Does the Content Group Work?

The editorial coordinator will be primarily responsible for the group’s work, receiving assistance from the deliberation expert when undertaking this work for the first time. The coordinator’s role involves interviewing experts, convening meetings, and drafting and producing the necessary documents for the deliberative curriculum. It is a very demanding job, requiring about two to three days per week, with an increased commitment in the months leading up to and during the Assembly. The content experts, in contrast, are expected to contribute an average of one or two hours per week during the whole process

The content provision methodology has two main phases. The first one begins at least two months, ideally three to four months before the start of the Assembly's deliberations and involves the creation of a deliberative curriculum. The second phase takes place during and between the deliberations of the Assembly, and we will call it ongoing content provision.

5.3. The Deliberative Curriculum

The deliberative curriculum is not a conventional curriculum for a school, but a somewhat special one in many ways. Firstly, it is aimed at an audience of different ages, educational levels, and abilities. Secondly, it should focus on tackling a political dilemma.

The main components of the curriculum are:

  • Content white paper. What specific information needs to be included to fulfil the objectives?
  • Tools and resources. What pedagogical tools are used for each information block? Which human and logistical resources are needed to implement the curriculum?

5.3.1. Creating the Content White Paper

In creating this initial document, the emphasis should not be on simplicity. Instead, the document should aspire to the standards of a white paper, prioritising robustness, coherence, and comprehensive referencing. This approach is vital to lay a solid foundation for an informed and substantive debate.

In order to establish a protocol for decision-making among the content experts, we consider it useful to establish some definitions of types of content:

  •  Basic content: This is information that has been agreed by the content experts. Everyone agrees that it is factual and should be presented.
  •   Balanced content: This is where there is no agreement among the content experts on what is factual or even whether it should be presented, so other differing views or additional information must be added to reach agreement.

The very first task of the content group will be to develop the basic structure of the deliberative curriculum. To do so, the following key aspects should be considered:

  •  Understand the dilemma. What content is needed to understand the dilemma?
  • Grasp the constraints. What are the constraints on government action? This includes considering past actions, planned initiatives, competences, the legislative calendar, and other potential constraints. What is the scope of the citizens’ recommendations? And what is the government's political compromise?
  •  Identify potential scenarios or models to move forward. What are the main different solutions for the dilemma? What information is needed to understand these solutions? Are all main potential solutions from key stakeholders included?

 Determine solution compatibility. Why are these solutions incompatible? What different legal or other actions can the government take in either direction? If the solutions are compatible, deliberation loses most of its impact, since both solutions can be listed as an expert-generated product.

  •   Evaluate the trade-offs. What are the trade-offs associated with each solution or between solutions? What information is needed to understand these trade-offs?

Based on this initial task, the content group must make a crucial decision: What is the minimum content required to ensure a viable deliberation? The content group should also decide how many scenarios can be explored, bearing in mind the need to consider the trade- offs involved. Prioritisation could be crucial at this stage. Removing blocks of information could involve rearranging the balance of content.

The editorial coordinator's primary responsibility is to thoroughly explore the diverse perspectives of the contributing experts. This includes a deep understanding of their background information, their individual arguments, and the nuances of their viewpoints. It is essential to discern and articulate the various lines of debate, as well as to identify any conflicts or incompatibilities present in their proposals.

To finalise the document, the editorial coordinator must ensure that it receives the explicit approval of all participating experts, confirming that it accurately represents their views and contributions. This consensus is crucial for the integrity and credibility of the document.

5.3.2.  Pedagogical Tools and Resources

Once the content group has the technical document, it will need to design how this content is exposed to citizens. To do this, different tools for dissemination and communication should be considered. The tools will feed the pedagogical component52 of the facilitation methodology for the Climate Assembly. An essential part of this process is assessing and prioritising the resources available to achieve an acceptable mix for information provision.

We need to consider here the following questions: Who presents the information and how? What resources are required? This will entail generating specific materials such as texts, videos, infographics, and interactive installations. It will also involve disseminators or other knowledge holders. An essential part of this process is assessing and prioritising the resources available to achieve an acceptable mix for information provision.

The first standard material that each Assembly produces is a written information kit on the dilemma. This document should be based on the white paper, but it should be an informative version of it, presented in plain language to ensure that all the contents are accessible and easily understood by everyone, regardless of their educational background. It is important to identify the parts that are more complex to translate into plain text, such as graphics or complex concepts. In these cases, appropriate infographics will be designed and integrated into the kit. A digital online format of the kit would also allow the addition of short explanatory videos.

It should be noted that not all citizens will read the kit. It is therefore important to consider how this kit is conveyed orally to citizens during the learning phase. For this, a programme of speakers will be produced, which should emulate a school class rather than an academic conference. This programme may have presentations, which should be curated by experts in plain language, panel discussions, or interactive dynamics between the audience and the speakers. Speakers could be not only experts but also other types of knowledge holders, such as witnesses or testimonies from affected people or interest groups.

Interactive activities can help participants to integrate complex concepts or ideas. These could be practical group exercises, games or interactive museum-style installations.

5.4. Ongoing Content Provision

The content and deliberation experts should be present during and between the deliberations in order to carry out the ongoing content provision.53 The aim of this stage is to reduce the risk of lack of knowledge and false or misleading information. These are some of the tasks associated with this phase:

  •   Answering participants’ queries: The content group should respond to participants’ questions with multiple, balanced answers, either during the meetings or in between.
  •  Monitoring meetings: Observe the assembly discussions to identify lack of knowledge and false or misleading information.
  •  Analysing session outcomes: Analyse the results of each session, pinpointing knowledge gaps and inaccuracies. Additionally, the content group can help with other tasks in between sessions, such as clustering content created by citizens.
  • Balancing information: Provide balanced information to counteract false or misleading data.
  •   Supplying additional resources: Provide citizens and the organisational team with extra knowledge or expert speakers as needed between sessions, either proactively or in response to citizens’ requests.

6. Democratic Lottery and Inclusion

One of the key features of deliberative processes is that participants are selected through a democratic or civic lottery. This means that the participants do not come through an open call but are invited through a lottery. The basic aim is to create a descriptive sample of the population based on certain socio-demographic criteria. In this chapter, we will explain how the democratic lottery works and what the key features should be when dealing with a defined policy dilemma.

6.1. The Method

The process consists of two phases. In the first phase, a lottery is held to select those who are to receive an invitation to register their interest, ideally giving every adult an equal chance of being invited. In the second, a stratified random draw is carried out to compensate for voluntariness biases. This is explained below.

6.1.1. The First Draw

The first draw should be based on the democratic principle of equal selection: Every adult should have an equal chance of being selected to receive an invitation. This principle is key, as it is one of the main drivers of the legitimacy of the whole process and has been used since ancient times.54

In order to comply with this principle of equality, an initial draw must be made from a database containing all the inhabitants. If such a database is available, a draw will be made on it to determine the initial number of citizens to be contacted (I) using this formula:

I = 200* N

Where N is the number of assembly members or size of the assembly. This formula is based on two fundamental facts based on experience in other processes:

  •  A conservative response rate to these invitations is approximately 4%.55 In practice it can vary widely from 2 to 12%.
  • The required number of citizen pool to perform quality stratification is P = 8 * N.

Thus, if we equalise the two conditions: 8 * N = 4% * I. And clearing it, we obtain the formula mentioned above: I = 200 * N.

To illustrate this, imagine an organisation aiming to form an Assembly with 50 members. Using the provided formula, the organisation would need to contact 10,000 citizens initially. Given the expected 4% response rate, it is anticipated that approximately 400 individuals will respond positively. This number aligns with the requirement to have a pool that is 8 times the size of the desired Assembly for quality stratification. Additionally, to account for potential vacancies before the Assembly commences, the organisation would also select an extra 10% as replacements,56 which equates to 5 additional members. Thus, while the target size of the assembly is 50, a total of 55 individuals (50 members plus 5 replacements) would be finalised from the pool.

It is important to note that if we do not have a database to sort the 200*N guests, we should use an approximation. A commonly used approximation is a database of postal addresses, as almost all residents, except the homeless, have an address. A less reliable method, but a good approximation in the absence of an integrated database of residential postal addresses, is street selection at points drawn by lot according to a criterion proportional to population density.57 Another method may be the generation of random telephone numbers.

6.1.2. Stratification Criteria

Once we have achieved an adequate pool of citizens, who have volunteered and accepted the assembly’s participation conditions, we have to carry out a second draw, this time stratified. Why is stratification necessary? While the first lottery guarantees diversity and independence, the usual 4% volunteer rate from the invited citizens introduces potential biases that we must try to compensate for. The stratification criteria aim to counterbalance these biases.59 These are the most commonly used criteria:60

  • Gender: There may be bias, and more men may participate; although in some countries this is no longer the case, in others, men may be more interested in political processes and more willing to get involved.
  • Age: In general, participation peaks in the middle age 40-50 years and decreases in older and younger people.
  • Place of residence: Certain rural or deprived areas may have lower levels of participation.
  • Socio-economic status: Determined by factors like education, occupation, income, household, and neighbourhood resources (Rodríguez-Hernández, Cascallar, & Kyndt, 2020). Those from lower socio-economic levels tend to participate less. Given the sensitivity around income and its correlation with education (Mou, 2023, p. 164), educational level is often asked to infer socio-economic status.

 The political Criterion Related to the Dilemma: The Attitudinal Criteria

A very strong bias is often related to political sensitivity towards the subject of the assembly. This criterion is key to our dilemma-centred methodology. If the assembly sample is biassed in relation to the dilemma, the process can be severely delegitimised.

In some countries, such as the US, it is customary to ask about voting recall. This may be sufficient given that political ideologies often align with the polarisation in most dilemmas.61 However, this requires asking a very sensitive question that many people may be suspicious of, especially if they distrust the convening government. In this methodology we propose better to ask an attitudinal question related to the dilemma. The attitudinal question is not as strongly perceived as an interrogation about your ideology as the vote recall or other more direct questions about ideology, but it is indirectly related.

The attitudinal question has to mirror a question that has been recently asked in a survey on the same population scale as the assembly sample.62 This question should be roughly connected to the dilemma. A common question in the context of climate change is often:

How concerned are you about climate change? A lot, some, a little, not at all.

We could also come up with more specific questions that would be better suited to the dilemma itself. The attitudinal criteria should be proposed by the project team and validated by the oversight group.

6.1.3. The Second Draw

The stratification has to reflect the reality of the population, so we must have the data of the chosen criteria in the population that the assembly intends to represent. From our pool of volunteer citizens, we have to make the stratification that best approximates the population data. In practice, there is no one-size-fits-all approach. There are always several ways to get approximate samples from the same pool of citizens. How do we justify the choice of selecting one sample over another?

First, we must sort the different possible samples according to their deviation from the overall population, giving priority to those with the least deviation. Then, we will make a second draw from among these samples with a minimum similar deviation. This second lottery establishes a fair criterion of choosing citizens who best represent the broader population. There are now computer algorithms capable of doing this process in mere seconds (Flanigan et al., 2021).

6.2. Inclusion Strategies

In democratic innovations such as Citizens’ Assemblies, the dynamics of participation differ significantly from the straightforward selection of lottery balls. Whereas each lottery ball has an impartial and equal chance of being selected, human participants exhibit a distinct pattern due to the voluntary nature of their involvement, leading to what is termed self-selection bias (Harris, 2019, p. 49). This bias is very strong: Around 96% of all invitations are not accepted. Although we have already seen that we can try to correct this by stratifying, there are other strategies to improve the acceptance of the invitation and minimise the effects of self- selection bias. These strategies are essential because there may always be hidden biases that cannot be corrected by the limited criteria of stratification.

Inclusion strategies try to maximise acceptance of the invitation. Here are some of the most common ones:

  •  Economic incentive: Many people who have no interest in the political process of participation may have an interest in earning money, especially the poorer social strata. This payment per session is recommended to be up to €100 per full day of work.
  •  All covered: Participation should not entail additional costs for citizens. Travel, meals, and accommodation should be covered and managed by agencies offering a personalised service.
  •  Distinguished treatment: Citizens should feel relevant and be treated like any other policy maker. Venues must be attractive, catering must be selected, and accommodation must be up to standard. The invitation must be signed by the highest government official.
  •  Letters certifying their participation: It may be vital for some citizens to request to miss a day of work or to leave earlier or arrive later to have an official letter.63
  •  Help for carers: Many carers of young children, elderly, or sick people find it difficult to leave their homes for several days. Allocating additional financial support for caregivers or creating spaces in assemblies to include caregivers is essential to facilitate their participation.
  • Inclusive language: Making the invitation easy to understand for anyone who is not used to reading complex texts and for people who understand different languages is essential. Special attention should be paid to this not only in the invitation but throughout the whole process.
  •  Plural and committed political space: Citizens must not feel that the participatory space is biassed. It is important to reflect at all times that the process incorporates politicians or experts from different political orientations. Alongside this pluralistic approach, a strong commitment from public decision-makers to the initiative has been a key factor in cases with high response rates and low dropout rates (OECD, 2020, p. 93).
  • Tacit knowledge: It is important to communicate that they "do not need" to know about a particular subject. Their life experience, whatever it may be, is what is required of them.
  • Special policy for people dealing with homelessness or extreme poverty:64 Collaborating with specialised NGOs, aids in reaching out to these populations. A minimum number of participants with the same characteristics should be selected to help them build a collective voice. Given the numerous challenges they have already faced, it is advisable to provide them with special accompaniment both before the whole process and before each meeting. Such accompaniment serves to facilitate their participation and prevent feelings of added failure.

6.3. Who Applies the Methodology?

It is common for the selection of participants through a democratic lottery to be delegated to an independent organisation outside the government. This ensures that no one in government has access to participants' data. If this is not the case, it is strongly recommended that the technical government staff having access to the data should not be political appointees.
