This chapter reflects on the election of Donald Trump and the vote of the British electorate in favour of ‘Brexit’ from the European Union. While we refrain from judging the outcomes of these votes, we do discuss concerns pertaining to the lack of truthfulness in both campaigns. After rehearsing the lies on which the Trump and Brexit campaigns were based, we consider different explanations as to why these campaigns were nevertheless successful, and where this leaves the argument for epistemic democracy. Particularly worrisome are tendencies towards ‘epistemic insouciance’, ‘epistemic malevolence’, and ‘epistemic agnosticism’. We also consider the problematic influence of social media in terms of echo chambers and filter bubbles. The core argument in favour of epistemic democracy is that the pooling of votes by majority rule has epistemically beneficial properties, assuming certain conditions. If these assumptions are not met, or are systematically corrupted, then epistemic democracy is under threat.

AbstractSocial media allow to fulfill perceived social needs such as connecting with friends or other individuals with similar interests into virtual communities; they have also become essential as news sources, microblogging platforms, in particular, in a variety of contexts including that of health. However, due to the homophily property and selective exposure to information, social media have the tendency to create distinct groups of individuals whose ideas are highly polarized around certain topics. In these groups, a.k.a. echo chambers, people only "hear their own voice,” and divergent visions are no longer taken into account. This article focuses on the study of the echo chamber phenomenon in the context of the COVID-19 pandemic, by considering both the relationships connecting individuals and semantic aspects related to the content they share over Twitter. To this aim, we propose an approach based on the application of a community detection strategy to distinct topology- and content-aware representations of the COVID-19 conversation graph. Then, we assess and analyze the controversy and homogeneity among the different polarized groups obtained. The evaluations of the approach are carried out on a dataset of tweets related to COVID-19 collected between January and March 2020.

Information Diversity

Social media have great potential to support diverse information sharing, but there is widespread concern that platforms like Twitter do not result in communication between those who hold contradictory viewpoints. Because users can choose whom to follow, prior research suggests that social media users exist in "echo chambers" or become polarized. We seek evidence of this in a complete cross section of hyperlinks posted on Twitter, using previously validated measures of the political slant of news sources to study information diversity. Contrary to prediction, we find that the average account posts links to more politically moderate news sources than the ones they receive in their own feed. However, members of a tiny network core do exhibit cross-sectional evidence of polarization and are responsible for the majority of tweets received overall due to their popularity and activity, which could explain the widespread perception of polarization on social media.

Echo Chambers

Abstract This paper investigates the link between social media and hate crime. We show that antirefugee sentiment on Facebook predicts crimes against refugees in otherwise similar municipalities with higher social media usage. To establish causality, we exploit exogenous variation in the timing of major Facebook and internet outages. Consistent with a role for “echo chambers,” we find that right-wing social media posts contain narrower and more loaded content than news reports. Our results suggest that social media can act as a propagation mechanism for violent crimes by enabling the spread of extreme viewpoints.

Low Levels

As trust in news media and social media dwindles and fears of disinformation and echo chambers spread, individuals need to find ways to access and assess reliable and trustworthy information. Despite low levels of trust in social media, they are used for accessing political information and news. In this study, we examine the information verification practices of opinion leaders (who consume political information above average and share their opinions on social media above average) and of opinion seekers (who seek out political information from friends and family) to understand similarities and differences in their news media trust, fact-checking behaviors, and likeliness of being caught in echo chambers. Based on a survey of French Internet users ( N = 2,000) we find that not only opinion leaders, but also opinion seekers, have higher rates across all three of these dependent variables. We discuss the implications of findings for the development of opinion leadership theory as well as for social media platforms wishing to increase trust.

Induced Polarisation

AbstractSocial media has played a pivotal role in polarising views on politics, climate change, and more recently, the Covid-19 pandemic. Social media induced polarisation (SMIP) poses serious challenges to society as it could enable ‘digital wildfires’ that can wreak havoc worldwide. While the effects of SMIP have been extensively studied, there is limited understanding of the interplay between two key components of this phenomenon: confirmation bias (reinforcing one’s attitudes and beliefs) and echo chambers (i.e., hear their own voice). This paper addresses this knowledge deficit by exploring how manifestations of confirmation bias contributed to the development of ‘echo chambers’ at the height of the Covid-19 pandemic. Thematic analysis of data collected from 35 participants involved in supply chain information processing forms the basis of a conceptual model of SMIP and four key cross-cutting propositions emerging from the data that have implications for research and practice.

Role And Function

This article tries to see a phenomenon called Echo Chambers through the perspective of Stella Ting-Toomey’s Intercultural Communication Theory. This study shows that the development of social media was also followed by the shadow of Echo Chambers. The tendency to isolate oneself and associate with those who understand one another will create separate spaces between one religion and another. As a result, communication which is an effort to eliminate the polarization of the differences between "Us" and "The Others" is precisely the way to form an exclusivism in cyberspace. Among the efforts to anticipate the emergence of a gap is to create melting-pot spaces in the real world. Counter narrative also needs to be built to open these exclusive barriers. Muslim scholars sought to introduce the importance of communication in achieving the harmony in community. Some Ulama have also explained the role and function of communication in achieving the goals of the ummah, as well as trying to provide an Islamic perspective regarding communication behavior. More important, is to create a person who is a wise, open user of social media and uses epoche in looking at the world outside.
