Civic lottery and citizen agreement

With access to sufficient information, and time, randomly selected citizens have demonstrated that they are very good critical thinkers. When part of a diverse group, they can, together, explore alternatives, make trade-offs and make excellent collective decisions

Lyn Carson, newDemocracy Foundation

Our deliberative methodology includes

  • Groups of citizens selected through civic lottery to form a descriptive sample of the population.
  • Access to experts of all trends.
  • The use of facilitation techniques to reach agreements.

What do we achieve?

Involve people from diverse backgrounds who are not usually involved in public decision-making.
Combat misinformation in public opinion through informed discussion.
Help governments to address relevant and long-term decisions by building trust among citizens.

CLIMAS | Citizen engagement toolbox for climate change adaptation

Within a Consortium composed of cambiaMO, Vilnius Tech University, Deliberativa, Fundació EURECAT and the Departament d’acció exterior i govern obert – Generalitat de Catalunya.

Lead Institution: European Union, Horizon Europe programme

CLIMAS aims to support a transformation towards climate resilience by offering an innovative toolbox that includes, among others, deliberative mechanisms.

In this framework, Deliberativa focuses on how to generate the best framing (mandate) for citizens’ assemblies, and the best way to manage the knowledge that is transmitted to the Assembly, focusing on the Climate Assembly of Catalonia. The aim is to move from climate assemblies that provide technical answers (guided by expert knowledge) to assemblies that solve value-centred dilemmas (taking into account different stakeholder positions).

"Broadening Democracy" Campaign, Spain

Action plan designed with Political Watch y Komons

The objective of Ampifying Democracy campaign is to achieve a broad political and administrative commitment and broad social support to advance in a democratic renewal in Spain based on citizen participation and deliberation. Three axes of work from Deliberativa:

  • disseminating and promoting deliberative practices in civil society and institutions:
    • Amplifying Democracy Manifesto (February 2024). Annex 3: Incorporating deliberative processes and citizens’ assemblies into public decision-making processes
    • For a Citizens’ Convention on Housing in Spain (April 2024). We promote, together with Gobierno Transparente, the holding of a deliberative process on housing, in order to think about long-term policies that do not depend on electoral changes.
  • accompanying governments in the initial phase of conceptualising and designing deliberative assemblies: we are working with public administrations in several territories.
  • initiating in 2023 Delib, a network of Deliberative democracy promoters in the Iberian Peninsula.

During those years he was part of the design team and coordinator of the G1000 Madrid and the City Observatory (the first permanent deliberative body).

In 2019 he founded Deliberativa together with Arantxa Mendiharat. In these years they help to design and implement multiple local and regional projects (see list). He has a special interest in transnational deliberation. He has been heavily involved as part of the core design and coordination team in the Future of Europe Conference, the Next Generation European Panels, and the Global Assembly on Climate Emergency (see list).
