Defining Collective Identities in Technopolitical Interaction Networks

I collaborated with Antonio Calleja and Emanuele Cozzo to deliver this piece of research. It has been hard work to delve deep into sociology but very gratifying.

The notion of “collective identity” plays a central role in contemporary society and its theorizing. We distinguish three broad categories of understanding collective identities: a) people share a collective identity when they share a common trait, b) people share a collective identity when they represent themselves as belonging to a specific category, c) people participate in a collective identity when they interact within a specific network of relationships. This last conception holds special relevance today: people organize by means of digital interaction networks and data is available for analysis with mature computational methods. However, there is currently no available formal definition of how to characterize collective identities emerging from digital interaction networks. We provide such a definition conceiving of collective identities as recurrent, cohesive and coordinated communicative interaction networks. We distinguish identity-cores (the organizational nucleus of coordinated agents), identity audiences that get influenced and broadcast information from the core, and the identity sources that inform and feed the core. We theoretically justify computational procedures to characterize collective identities in this way and applied them to three case studies on Facebook and Twitter. We finally discuss how this characterization relates to other dimensions of collective identity and its contemporary technopolitical relevance.

Sensorimotor Life. An Enactive Proposal (the Book)

Cover image of Sensorimotor Life

It has been some time now since we published this book. At the time I was too busy working at Barcelona City Council and could not publish a post on this blog. It is now time to do so.

Chapters 5 and 6 of the book are based on my PhD thesis and I am proud to see it published within the more ellaborate framework of this book.

From the official summary of the book: «Sensorimotor Life draws on current theoretical developments in the enactive approach to life and mind. It examines and expands the premises of the sciences of the human mind, while developing an alternative picture closer to people’s daily experiences. Enactive ideas are applied and extended, providing a theoretically rich, naturalistic account of meaning and agency. The book includes a dynamical systems description of different types of sensorimotor regularities or sensorimotor contingencies; a dynamical interpretation of Piaget’s theory of equilibration to ground the concept of sensorimotor mastery; and a theory of agency as organized networks of sensorimotor schemes, as well as its implications for embodied subjectivity.»

The book is available online in various formats. You can download a PDF version of «Sensorimotor Life. An Enactive Proposal» here.

Comparativa Decidim vs. Cónsul

Comparativa Decidim vs. Cónsul

Mucha gente me pregunta cuales son las diferencias entre Decidim y Cónsul, las dos plataformas de participación democrática desarrolladas en Barcelona y Madrid respectivamente. Los proyectos son bastante parecidos y a menudo la gente se pregunta qué es lo que los diferencia y cuál se adapta mejor a sus necesidades.

En este post presento una tabla comparativa de las diferencias y las funcionalidades de Cónsul y Decidim. También voy a contaros cuales son las diferencias más profundas entre los dos proyectos, a nivel de concepto, comunidad y filosofía. Es un conocimiento inevitablemente sesgado e incompleto, porque no conozco Cónsul tan bien como conozco Decidim (del que fui fundador y coordinador), pero he hecho un gran esfuerzo por ser equitativo. Espero además poder actualizar esta entrada con los comentarios y las aportaciones que hagáis.

What is Decidim?

Many people ask what is this project called «Decidim» to which I have devoted my last two year of work with complete dedication. I wanted to share a brief summary here. This text is the introduction of the Decidim’s White Paper (I am writing with Antonio Calleja and Arnau Monterde), to be published soon. I have systematized this text myself but it is really the product of a big group of people that have contributed to this project since its inception (Arnau Monerde, Andrés Lucena, Antonio Calleja, Carol Romero, Pablo Aragón and many others).

Table of contents


Decidim [http://decidim.org], from the Catalan «let’s decide» or “we decide”, is a digital infrastructure for participatory democracy, a digital platform, built entirely and collaboratively as free software. More specifically, Decidim is a web environment (a framework) produced in Ruby on Rails (a programming language) that allows anybody to create and configure a website platform to be used in the form of a political network for democratic participation. The platform allows any organization (local city council, association, university, NGO, neighbourhood or cooperative) to create mass processes for strategic planning, participatory budgeting, collaborative design for regulations, urban spaces and election processes. It also makes possible to connect traditional in-person democratic meetings (assemblies, council meetings, etc.) with the digital world: sending meeting invites, managing registrations, facilitating the publication of minutes, etc. In addition, Decidim enables the structuring of government bodies or assemblies (councils, boards, working groups), the convening of consultations, referendums or channelling citizen or member initiatives to trigger different decision making processes. Yet, the Decidim project is much more than that.


Decidim is a public-common’s, free and open, digital infrastructure for participatory democracy. It is convenient to explain the terms of this definition in inverse order.

By “participatory democracy” we mean that form of “government of the people and by the people” in which people take part as equals or peers (from latin pars, part, and capere, to take). By taking part we mean that people take the part of sovereignty of political life that belongs to them. And this should be an equal part for each, democracy is something that is done among peers.

The term “digital infrastructure” makes reference to a set of tools, resources, data-sets, documents, codes (legal, computer, etc.), interfaces and services that are digitalized or made accessible by digital means. This infrastructure is primarily a software platform for participatory democracy. Participants can create proposal, sign and support them, comment, receive notifications, attend public meetings or receive the minutes. Administrators can design participatory processes, define organs, configure types of initiatives or set up consultations. The infrastructure also includes documentation, design (icons, images, logos, etc.), legal documents, datasets or training resources, among others. All these, when organized as an infrastructure, make possible to deploy a participatory democratic system in any organization (be it a municipality, a cooperative, an association, a union or a community).

By “free and open” we mean that the project’s goods (the assets of the infrastructure) do no fall under the form of private property, that excludes others from access, usage, copy, modify and re-publish or reuse these resources but, instead, displays all the legal, technical and social means necessary to share them and open them to collaboration.

Finally, the term “public-common’s” indicates that the project is mostly financed and made possible by public institutions and is managed and designed by an open community constituted by public-servants, members of different associations, university researchers and students, activists and staff from foundations, workers from different companies or simply volunteers that commit to the principles of the project. For this infrastructure to be a common’s it is important that these partners organize democratically in relation to the project. In this sense Decidim is a reflexive infrastructure that uses the very infrastructure to democratize itself. decidim-context

Platform features and functional architecture

Since the digital platform displays and embodies both the means of project organization and its democratic principles, it is important to explain how the platform works. Users of the platform (participants) interact through participatory mechanisms known as components within different participatory spaces that channel their democratic power to specific results. These are the frameworks that define how participation will be carried out, the channels or means through which citizens or members of an organization can process requests or coordinate proposals and make decisions. Initiatives, Processes, Assemblies and Consultations are all participatory spaces. Specific examples of each of these include: a citizen initiative for directly changing a regulation (Initiative); a general assembly or workers’ council (Assembly); a participatory budgeting, strategic planning, or electoral process (Processes); a referendum or call to vote “Yes” or “No” to change the name of an organization (Consultation). The more notable components that are combined into spaces to deliver participatory mechanisms include in-person meetings, proposals, blogs, debates, static information pages, surveys, votes, results and comments. So, for example, the various phases of a participatory budgeting process (where members of an organization are called to decide how to spend a budget) can combine components in the following way: at an early phase public meetings can be opened for citizens to analyze different needs classified by districts. In turn these meetings can lead to the design of a survey. The survey results can next be used to define a set of categories for projects to be proposed. The proposal component might then be activated for participants to create and publish their projects as solutions to the identified needs. These proposals can be commented and after two weeks of deliberation the voting component can be activated to select among the projects with a budget-expenditure system. Participants can then be called to a public meeting to evaluate the results and an assessment survey can then be launched for those who could not attend the meeting. Finally, the accountability component can be activated to monitor the degree of execution of the selected projects and people can comment on it. This is but one example of how components are combined in a space, but there are many other combinatorial possibilities. What makes Decidim particularly powerful is this combination of components within spaces, which provides an organization with a complete toolkit to easily design and deploy a democratic system adapted to its needs.

The social contract

All members and partners of the Decidim project must endorse and follow a “social contract” (https://decidim.org/contract) that defines a set of guiding principles. The social contract can be summarized as follows: 1. Free software and open content: Decidim will always remain free and open to collaboration, without legal or technical obstacles for the use, copy and modification. To ensure this we use a set of licenses: Affero GPLv3 for the code, CreativeCommons By-SA for the content (text, images, design, etc.) and Open Access Database License for data. This means that Decidim will always remain auditable, collaborable, transparent, appropriable and trustworthy, all of which is fundamental for a democratic infrastructure. 2. Transparency, traceability and integrity: the content of participation will always remain transparent, traceable and integral. This means that all the content must be accessible and downloadable, it should always be known what happens with each proposal, its origin, in which result or decision is was incorporated or why it was rejected or left behind, and the content needs to be displayed without been manipulated, any modification (if required) must be registered and be accessible and auditable. 3. Equal opportunities: “The platform will offer equal starting opportunities to all participatory objects (proposals, debates, etc.) for them to be viewed, discussed, commented, evaluated or treated without discrimination of any kind” (direct quote from the contract). 4. Privacy with verification: participants must retain privacy of their personal data combined with verification. Personal data should never be displayed, nor sold or transferred to third parties while, at the same time, the unicity and democratic rights of participants must be preserved (meaning there cannot be two verified users corresponding to the same individual with democratic rights and all participants with such rights must be verifiable). 5. Democratic quality and guarantees: the platform must guarantee the democratic quality, the non-discrimination and equal opportunities for each participant and proposal. 6. Inclusiveness and multilayerness: the platform must comply with accessibility standards, its use must favour the integration of online and offline participation and organizations must deploy the means for mediation and training of participants.


The best known and intensively used instance of Decidim, as a digital platform for participatory democracy, is www.decidim.barcelona, with (as of March the 1st) more than 28,000 registered participants, 1,288,999 page views, 290,520 visitors, 19 participatory processes, 821 public meetings channeled through the platform and 12,173 proposals, out of which over 8,923 have already become public policies grouped into 5,339 results whose execution level can be monitored by citizens. The instance that actively explores more functionalities is meta.decidim.org, the community portal that designs and supports the project. There is also a demo site with the latest version available for exploration and a training instance open to anybody to learn how to configure, administrate and use the platform. There are currently more than 20 instances of Decidim for organizations of different sorts ranging from municipalities such as Helsinki or Pamplona, to regional governments like the Junta de Castilla la Mancha or the Generalitat de Catalunya, NGO networks such as Fundaction or QuorumGlobal, cooperatives like Somenergia, or the National Commission for Public Debate (Commission Nationale du Débat Public) in France.

A sustainable ecosystem

Developed at Barcelona’s Laboratory for Democratic Innovation, Decidim is the result of the joint effort of a network of collaborating entities and multiple participants leaded by Barcelona’s City Council. Appart from the organizations that use the platform and whose participants and administrators report bugs and suggest improvements, there is a network of 17 different collaborating entities, from software companies to institutional consortia, from research institutions to civil associations. The meta.decidim community uses an instance of the Decidim platform to organize the different dimensions of the project. As of April the 21st it has over 300 registered users, it hosts minutes of over 112 public meetings, details of 8 assemblies or working groups, 4 participatory processes (welcome process, bug reporting, feature proposals, and training workshop process) together with various initiatives and a consultations aimed at defining the roadmap and software design of the platform, bug reporting, community and project governance, research and development. Official documentation and code are developed on Github (https://github.com/decidim) where the project hosts 21 repositories with over 41 developers’ contributions. They all together generate a sustainable ecosystem that governs, produces and provides services over the platform (deployment, adaptation, configuration, training, consultancy, administration, etc.).

Democracy and social empowerment

Decidim was born in an institutional environment (that of Barcelona City Council), directly aiming at improving and enhancing the political and administrative impact of participatory democracy in the state (municipalities, local governments, etc.). But it also aims at empowering social processes as a platform for massive social coordination for collective action independently of public administrations. Anybody can copy, modify and install Decidim for its own needs, so Decidim is by no means reduced to public institutions. There are different ways in which participatory democracy infrastructures can boost social, economic and political self-organization. Decidim is starting to be used for these purposes: for the internal organization of consumer and producer cooperatives for example, it is also helping youth movements organize and design strategic planning, and it might soon be used to coordinate massive strikes or other forms of social action. The modular nature of the software architecture is also making possible for these organization to develop their own components and improvements (such as crowdfunding, membership management, etc.) and to plug them into Decidim, expanding its potential. Corporate digital platforms (Amazon, AirBnB, etc.) are disrupting private services and markets. Decidim comes to fill the gap of public and common’s platforms, providing an alternative to the way in which private platforms coordinate social action (mostly with profit-driven, data extraction and market oriented goals).

The political, the technical and the technopolitical

As we have repeatedly stressed, Decidim is more than a technological platform. It has required to assemble a variety of codes, realities and dimensions that go beyond programming code. We define it as a “technopolitical project” where legal, political, institutional, practical, social, educational, communicative, economic and epistemic codes merge together. Ultimately, Decidim is in itself a sort of crossroad of the various dimensions of networked democracy and society, a detailed practical map of their complexities and conflicts. We distinguish three general planes or dimensions of the project: the political (focused on the democratic model that Decidim promotes and its impact on public policies and organizations), the technopolitical (focused on how the platform is designed, the mechanisms it embodies, and the way in which it is itself democratically designed), and the technical (focused on the conditions of production, operation and success of the project: the factory, collaborative mechanisms, licenses, etc.). The political plane is best illustrated by the use of Decidim in a city or organization, the type of democratic processes and decisions that are made through it. In other words, it covers what kind of politics can be done using Decidim: what kind of governance, conflict and power relationships can be channeled through it: the kind of democracy it is capable to produce. Its model instance is decidim.barcelona, what happens within, how it alters the political space of the city. The second plane, the technopolitical, includes matters concerning the digital architectural design of Decidim: its interfaces, features, design principles, data policies, user experience, etc. It is a primarily a reflexive space of how technologies structure political processes. It is embodied in the meta.decidim platform and the community that surrounds it. Finally, the technical plane encompasses issues concerning primarily the programming and legal codes (information and legal infrastructures), but is also includes issues of education and knowledge (epistemic infrastructures). All three dimensions are part of the project.

Identidad, censo, privacidad, poder

Existe versión colaborable de este documento en Gist.

El problema de cómo gestionar y auto-gestionar las identidades digitales tiene una importancia creciente para el futuro de la democracia y, sobre todo, para el futuro de la autonomía social respecto de otros centros de poder que comienzan a ser disruptivos (no ya de los modelos empresariales dominantes sino de los mecanismos de resistencia desarrollados durante el S.XX). Este documento pretende diagnosticar una situación compleja, identificar las ventanas de oportunidad que se abren el contexto actual y realizar una propuesta de arquitectura o protocolo de gestión de identidades (DIP: Decidim Identity Protocol) capaz de explotar las oportunidades actuales para aumentar la autonomía social y el impacto de la democracia participativa. Proponemos un sistema de identidad digital anónima pero administrativamente certificada, privadamente custodiada y públicamente verificable.

Interaction Dynamics and Autonomy

maguilera_thesis-2I am glad to post that Miguel Aguilera presented his PhD thesis and is now officially a doctor in cognitive science by the University of Zaragoza. His thesis «Interaction Dynamics and Autonomy in Cognitive Systems» is a rare, challenging, broad, audacious and brilliant contribution to the study of autonomous systems. How does a «self» or an «autonomous system» emerge and constitute itself through interactions with the environment? It seems the answer is impossible to provide, you need to have a self, an identity, before it starts interacting with the environment, but, at the same time, some forms of sensorimotor or cognitive identity emerge and sustain themselves through interactions. You are an example yourself: your identity is the result of your actions, and your actions are caused by you. How could this be? Can we formalize and model this type of emergence of autonomous organizations through interactions? This is the fundamental question addressed by Dr. Aguilera. And the results are innovative, profound, operational and insightful. The core of the thesis is a robotic model capable to switch spontaneously between different behavioural preferences, and whose control architecture is itself a novel contribution to robotics: a kuramoto oscillatory network whose connections plastically change so as to keep macroscopic relationships homeostatic. The robot is a system that is capable to maintain its own behavioural organization while shifting preferences. Nothing is hard-coded, the controller is designed using a carefully scaffolded evolutionary optimization algorithm that gave rise to a complex dynamical system that shows macroscopic properties that emerge from distributed interactive processes at different timescales.

But this is not the major contribution of the thesis.

Autonomy and Enactivism

I have finished the last revision of journal paper entitle «Autonomy and Enactivism«. It explores the conceptual tension between the concept of autonomy (self-organized closure of neural activity) and the sensorimotor constitution of cognition. I have long witnesses a generalized confusion, whose roots I explore in the paper, between two major schools of enactivism (the cognitive science paradigm that focuses on sensorimotor coupling and self-organized dynamics of brain, body and environment). On the one hand what I have called «sensorimotor enactivism», a school that has gained momentum thanks to the work of Alva Noë and Kevin O’Regan on sensorimotor contingencies. On the other hand what I have called «autonomist enactivism» with a particular focus on biological embodiment and the self-organized nature of brain and body. The gap between both schools has being growing recently, partly motivated by the lack of a clear notion of sensorimotorly constituted neurodynamic autonomy. Building upon the work I have been doing with my colleagues (Di Paolo, Buhrman, Santos, Aguilera and Bedia) during the last years I hope to have contributed to the compatibility and mutual reinforcement between both schools of thought. It is a long paper, and the contribution does not limit to a historical or contingent dispute between schools of thought: the reconciliation demands to develope a theory of sensorimotor autonomous agency and touches upon foundational aspects of cognitive science, from the emergence of norms to the epistemology of mechanistic explanations.
