The epistemic position of an agent often depends on their position in a larger network of other agents who provide them with information. In general, agents are better off if they have diverse and independent sources. Sullivan et al. [19] developed a method for quantitatively characterizing the epistemic position of individuals in a network that takes into account both diversity and independence; and presented a proof-of-concept, closed-source implementation on a small graph derived from Twitter data [19]. This paper reports on (...) an open-source reimplementation of their algorithm in Python, optimized to be usable on much larger networks. In addition to the algorithm and package, we also show the ability to scale up our package to large synthetic social network graph profiling, and finally demonstrate its utility in analyzing real-world empirical evidence of ‘echo chambers’ on online social media, as well as evidence of interdisciplinary diversity in an academic communications network.

People have always shared information through chains and networks of testimony. It’s arguably part of what makes us human and enables us to live in cooperative communities with populations greater than the Dunbar number. The invention of the Internet and the rise of social media have turbo-charged our ability to share information. In this chapter, we develop a normative framework for sharing information online. This framework takes into account both ethical and epistemic considerations that are intertwined in typical cases of (...) online testimony. We argue that, while the current state of affairs is not entirely novel, recent technological developments call for a rethinking of the norms of testimony, as well as the articulation of a set of virtuous dispositions that people would do well to cultivate in the capacity as conduits (not just sources or receivers) of information.

Social epistemologists should be well-equipped to explain and evaluate the growing vulnerabilities associated with filter bubbles, echo chambers, and group polarization in social media. However, almost all social epistemology has been built for social contexts that involve merely a speaker-hearer dyad. Filter bubbles, echo chambers, and group polarization all presuppose much larger and more complex network structures. In this paper, we lay the groundwork for a properly social epistemology that gives the role and structure of networks their due. In particular, (...) we formally define epistemic constructs that quantify the structural epistemic position of each node within an interconnected network. We argue for the epistemic value of a structure that we call the (m,k)-observer. We then present empirical evidence that (m,k)-observers are rare in social media discussions of controversial topics, which suggests that people suffer from serious problems of epistemic vulnerability. We conclude by arguing that social epistemologists and computer scientists should work together to develop minimal interventions that improve the structure of epistemic networks. (shrink)

This paper proposes three principles for the ethical design of online social environments aiming to minimise the unintended harms caused by users while interacting online, specifically by enhancing the users’ awareness of the moral load of their interactions. Such principles would need to account for the strong mediation of the digital environment and the particular nature of user interactions: disembodied, asynchronous, and ambiguous intent about the target audience. I argue that, by contrast to face to face interactions, additional factors make (...) it more difficult for users to exercise moral sensitivity in an online environment. An ethics for social media user interactions is ultimately an ethics of human relations mediated by a particular environment; hence I look towards an enactive inspired ethics in formulating principles for human interactions online to enhance or at least do not hinder a user’s moral sensitivity. This enactive take on social media ethics supplements classical moral frameworks by asking us to focus on the relations established through the interactions and the environment created by those interactions.

The aim of the article is to reflect on the communication model of fake news, starting from the assumption that fake news items are not mere falsehoods (e.g., trivial lies) nor something completely new.Drawing inspiration from the work of Umberto Eco, I will investigate the idea that today’s viral fake news can be aligned with the hermetic paradigm he outlined. Then I will consider another communicative model: that of gossip. Thanks to these two models, I will support the thesis that (...) fake news are not something to eliminate or to correct according to the criterion of evidence or truth, but rather something to live with, corresponding to a potentiality of discourse, that is to detect and to analyze.

In the past two decades, epistemologists have significantly expanded the focus of their field. To the traditional question that has dominated the debate — under what conditions does belief amount to knowledge? — they have added questions about testimony, epistemic virtues and vices, epistemic trust, and more. This broadening of the range of epistemic concern has coincided with an expansion in conceptions of epistemic agency beyond the individualism characteristic of most earlier epistemology. We believe that these developments have not gone (...) far enough. While the weak anti-individualism we see in contemporary epistemology may be adequate for the kinds of cases it tends to focus on, a great deal of human knowledge production and transmission does not conform to these models. Furthermore, the dispositions and norms that are knowledge-conducive in the familiar cases may not be knowledge-conducive generally. In fact, dispositions that, at an individual level, count as epistemic vices may be epistemic virtues in common social contexts. We argue that this overlooked feature of human social life means that epistemology must become more deeply and pervasively social. (shrink)

My main aim in this paper is to examine whether gossip should be categorized as an epistemically valuable character trait. Gossip satisfies the necessary and jointly sufficient conditions for an acquired character trait to be classified as an intellectual virtue under the responsibilist understanding of the concept of virtue. The excellent gossiper is motivated to acquire epistemic goods through gossiping, reliably successful in acquiring epistemic goods through gossiping, competent at the activity of gossiping and good at judging when, with whom (...) and what to gossip. Nonetheless, I show that the excellent gossiper inflicts epistemic wrong on others. The excellent gossiper comes to intentionally acquire another person’s private information without their consent. This leaves virtue responsibilists with three options: resist my argument that gossip qualifies as a responsibilist virtue and/or that excellent gossiping inflicts epistemic wrong, bite the bullet and argue that the intellectually virtuous agent sometimes inflicts epistemic wrong on other agents intentionally, develop a no-wrong principle that disqualifies gossip from being categorized as an intellectual virtue.

My aim in this paper is to present and discuss a novel understanding of the nature of epistemic vice. I highlight that epistemic vice such as excessive curiosity, gossip and excessive inquisitiveness do not obstruct the acquisition, transmission and retention of knowledge and are not characterized by a deficiency of epistemic desires or vicious epistemic motivations. However, I argue that such traits ought to be classified as epistemic vices because the agent who possesses them causes epistemic harm to other agents (...) through those traits’ characteristic activities.To remedy obstructivism’s inability to account for vices that cause epistemic harm in other ways besides blocking effective epistemic inquiry, I propose an amended version of this theory. I argue that epistemic vices are character traits, attitudes, and ways of thinking that obstruct the acquisition, transmission, and retention of knowledge and/or cause other kinds of epistemic harm. In addition, I propose a modified version of motivationalism that cashes out non-obstructing, excess-motivation vices in terms of motivation simply by acknowledging, and incorporating into theory, excessive epistemic drives and the negative epistemic (and non-epistemic) consequences stemming from them.

Gossip is pervasive and complex. It lubricates and wrecks social relationships. Many people openly confess to loving “a good gossip” yet acknowledge that gossiping, while often gratifying, is sometimes morally problematic. Surprisingly, gossip has not received much attention in moral philosophy. In this article, I argue that, notwithstanding its valuable relational and social functions, it is wrongful, at least in some of its forms, when and to the extent that it amounts to a particular kind of failure to treat others (...) (be they gossipees or fellow gossipers) with the concern and respect they are owed as persons. (shrink)

In the age of the Internet, people have increased access to information along multiple dimensions. It might seem that we are on our way to an epistemic utopia in which we spend less time and effort on basic cognitive tasks while devoting more time and effort to complex deliberation. However, though there are many accurate sources on the Internet, they must be sifted from the spammers, concern trolls, practical jokers, conspiracy theorists, counterintelligence sock-puppets, and outright liars who also proliferate online. (...) We can approach this problem via the individual or via the network, asking two questions. First, holding the topology of the network constant, which moral and epistemic dispositions are conducive to successful inquiry by nodes at different positions within it? Second, holding the distribution of people’s epistemic dispositions constant, which network topologies are more likely to produce epistemic goods and avoid epistemic ills? To answer these questions, we need to combine virtue-theoretic reflection on individual dispositions with a nuanced understanding of the dynamics of networks. In this paper, I highlight and explore some important properties of such networks and connect those properties with dispositions that make someone an excellent member of an epistemic network.

In paradigmatic cases of subtweeting, one Twitter user critically or mockingly tweets about another person without mentioning their username or their name. In this chapter, we give an account of the strategic aims of subtweeting and the mechanics through which it achieves them. We thereby hope to shed light on the distinctive communicative and moral texture of subtweeting while filling in a gap in the philosophical literature on strategic speech in social media. We first specify what subtweets are and identify (...) the central features that give rise to their strategic mechanics. Next, we draw attention to problematic aspects of subtweeting and consider conditions under which subtweeting can be justified on moral and prudential grounds. The chapter concludes by discussing practical upshots and noting avenues for future work. (shrink)
