Debate is a social process of interactive communication. We can distinguish at least four roles associated with parties to a debate. First, there are the debaters themselves \u2014 at least two of them, but possibly more. Second, there is the moderator of the debate. Third, there are the partisan audiences affiliated with each debater. Fourth, there is the unaffiliated audience. In a typical two-sided debate, each debater attempts to rally their partisans, sway the unaffiliated, stymie their opponent, demoralize their opponent\u2019s partisans, and manage the moderator. Note that none of this has to do with establishing claims based on evidence or transmitting knowledge. Debate only leads to these epistemic<\/em> consequences when it is well-structured and enough participants play by the rules.<\/p>\n

In my research on public discourse, I aim to map and evaluate the structure of the networks involved in debates. I\u2019ve chosen to focus on debates about controversial topics such as religiously-motivated violence, gay marriage, vaccination, genetically modified organisms, police brutality, income inequality, sexual harassment and assault, and abortion. Together with my team of computer scientists, data scientists, and philosophers, I am in the process of downloading posts on various social media networks related to these topics. Our plan is then to map, visualize, and analyze the networks of engagement associated with each controversy on each platform. For example, on Twitter we pay attention to replies, mentions, and retweets of tweets about the controversies. On Reddit, we pay attention to replies, up-votes, down-votes, and so on.<\/p>\n

The idea behind this project is that different networks are liable to emerge from platforms with different functionalities and user populations. Epistemically fruitful debate should therefore be more likely on some platforms about some controversial topics than on other platforms and about other controversial topics. While the project is exploratory, we have some hunches about some network features that should make a difference. When it comes to the location of particular nodes in the network (i.e., accounts and the users behind them), we have several specific expectations. First, nodes that receive their information third-, fourth-, and fifth-hand are in less safe epistemic positions. They\u2019re liable to accept hearsay. Second, nodes that receive their information from multiple independent<\/em> sources are more likely to arrive at an epistemically defensible position. Third, nodes that transmit to multiple receivers that don\u2019t communicate with each other enjoy enhanced rhetorical power, both as primary sources and as conduits of information.<\/p>\n

In the figure below, you can see an example of the third point. The two networks pictured are identical. On the left, you see the result of an iterated communication process starting with the node at the hub of the left portion of the graph. On the right, you see the result of the same number of iterations starting with the node at the hub of the right portion of the graph. The darker the node, the more convinced it is. As you can see, the node on the left has much more power to infect the network with its message than the node on the right. This is due solely to the structure<\/em> of the network and the position each node occupies within it.<\/p>\n

\"\"<\/p>\n

Whereas these fairly small graphs are based on simulated data, the graphs we are planning to build based on real data are going to be massive, containing thousands of nodes and tens of thousands of connections. They should enable us to track epistemic and rhetorical processes online, and will serve as food for thought in the social epistemology of communication networks.<\/p>\n
