Several earlier posts have focused on the theory of deliberative democracy (link, link, link). The notion is that political decision-making can be improved by finding mechanisms for permitting citizens to have extended opportunities for discussion and debate over policies and goals. The idea appeals to liberal democratic theorists in the tradition of Rousseau -- the idea that people's political preferences and values can become richer and more adequate through reasoned discussion in a conversation of equals, and political decisions will be improved through such a process. This idea doesn't quite equate to the wisdom of the crowd; rather, individuals become wiser through their interactions with other thoughtful and deliberative people, and the crowd's opinions improve as a result.
Here is the definition of deliberative democracy offered by Amy Gutmann and Dennis Thompson in Why Deliberative Democracy? (2004):
Most fundamentally, deliberative democracy affirms the need to justify decisions made by citizens and their representatives. Both are expected to justify the laws they would impose on one another. In a democracy, leaders should therefore give reasons for their decisions, and respond to the reasons that citizens give in return... The reasons that deliberative democracy asks citizens and their representatives to give should appeal to principles that individuals who are trying to find fair terms of cooperation cannot reasonably reject. (3)All political reasoning inherently involves an intermingling of goals, principles, and facts. What do we want to achieve? What moral principles do we respect as constraints on political choices? How do we think about the causal properties of the natural and social world in which we live? Political disagreement can derive from disagreements in each of these dimensions; deliberation in principle is expected to help citizens to narrow the range of disagreements they have about goals, principles, and facts. And traditional theorists of deliberative democracy, from the pre-Socratics to Gutmann, Thompson, or Fishkin, believe that it is possible for people of good will to come to realize that the beliefs and assumptions they bring to the debate may need adjustment.
But something important has changed since the 1990s when a lot of discussions of deliberative democracy took place. This is the workings of social media -- blogs, comments, Twitter discussions, Facebook communities. Here we have millions of people interacting with each other and debating issues -- but we don't seem to have a surge of better or more informed thinking about the hard issues. On the one hand, we might hope that the vast bandwidth of debate and discussion of issues, involving enormous numbers of the world's citizens, would have the effect of deepening the public's understanding of complex issues and policies. And on the other hand, we seem to have the evidence of continuing superficial thinking about issues, hardening of ideological positions, and reflexive habits of racism, homophobia, and xenophobia. The Internet seems to lead as often to a hardening and narrowing of attitudes as it does to a broadening and deepening of people's thinking about the serious issues we face.
So it is worth reflecting on what implications are presented to our ideas about democracy by the availability of the infrastructure of social media. It was observed during the months of the Arab Spring that Twitter and other social media platforms played a role in mobilization of groups of people sharing an interest in reform. And Guobin Yang describes the role that the Internet has played in some areas of popular activism in China (link). This is a little different from the theory of deliberative democracy, however, since mobilization is different from deliberative value-formation. The key question remains unanswered: can the quality of thinking and deliberation of the public be improved through the use of social media? Can the public come to a better understanding of issues like climate change, health care reform, and rising economic inequalities through the debates and discussions that occur on social media? Can our democracy be improved through the tools of Twitter, Facebook, or Google? So far the evidence is not encouraging; it is hard to find evidence suggesting a convergence of political or social attitudes deriving from massive use of social media. And the most dramatic recent example of change in public attitudes, the sudden rise in public acceptance of single-sex marriage, does not seem to have much of a connection from social media.
Here is a very interesting report by the Pew Foundation on the political segmentation of the world of Twitter (link). The heart of their findings is that Twitter discussions of politics commonly segment into largely distinct groups of individuals and websites (link).
Conversations on Twitter create networks with identifiable contours as people reply to and mention one another in their tweets. These conversational structures differ, depending on the subject and the people driving the conversation. Six structures are regularly observed: divided, unified, fragmented, clustered, and inward and outward hub and spoke structures. These are created as individuals choose whom to reply to or mention in their Twitter messages and the structures tell a story about the nature of the conversation.
If a topic is political, it is common to see two separate, polarized crowds take shape. They form two distinct discussion groups that mostly do not interact with each other. Frequently these are recognizably liberal or conservative groups. The participants within each separate group commonly mention very different collections of website URLs and use distinct hashtags and words. The split is clearly evident in many highly controversial discussions: people in clusters that we identified as liberal used URLs for mainstream news websites, while groups we identified as conservative used links to conservative news websites and commentary sources. At the center of each group are discussion leaders, the prominent people who are widely replied to or mentioned in the discussion. In polarized discussions, each group links to a different set of influential people or organizations that can be found at the center of each conversation cluster.And here is the authors' reason for thinking that the clustering of Twitter conversations is important:
Social media is increasingly home to civil society, the place where knowledge sharing, public discussions, debates, and disputes are carried out. As the new public square, social media conversations are as important to document as any other large public gathering. Network maps of public social media discussions in services like Twitter can provide insights into the role social media plays in our society. These maps are like aerial photographs of a crowd, showing the rough size and composition of a population. These maps can be augmented with on the ground interviews with crowd participants, collecting their words and interests. Insights from network analysis and visualization can complement survey or focus group research methods and can enhance sentiment analysis of the text of messages like tweets.Here are examples of "polarized crowds" and "tight crowds":
There is a great deal of research underway on the network graphs that can be identified within social media populations. But an early takeaway seems to be that segmentation rather than convergence appears to be the most common pattern. This seems to run contrary to the goals of deliberative democracy. Rather than exposing themselves to challenging ideas from people and sources in the other community, people tend to stay in their own circle.
So this is how social media seem to work if left to their own devices. Are there promising examples of more intentional uses of social media to engage the public in deeper conversations about the issues of the day? Certainly there are political organizations across the spectrum that are making large efforts to use social media as a platform for their messages and values. But this is not exactly "deliberative". What is more intriguing is whether there are foundations and non-profit organizations that have specifically focused on creating a more deliberative social media community that can help build a broader consensus about difficult policy choices. And so far I haven't been able to find good examples of this kind of effort.
(Josh Cohen's discussion of Rousseau's political philosophy is interesting in the context of fresh thinking about deliberation and democracy; link. And Archon Fung and Erik Olin Wright's collection of articles on democratic innovation, Deepening Democracy: Institutional Innovations in Empowered Participatory Governance (The Real Utopias Project) (v. 4), is a very good contribution as well.)
