Conspiracy theories are increasingly rife on the Internet. With their potential for spreading virally, they can reach large audiences across the globe. In their relentless drive to connect the dots into one over-arching explanation, conspiracy theories seem to be made for the hyperlinked world of the Internet. Once marginal ideas now readily find an online community of believers. Although conspiracy theories encountered online are at times merely harmless entertainment or a sign of healthy scepticism, they can also lead to a loss of faith in scientific authorities and expert knowledge, to political disengagement, and even to violence. This research project addresses the question of how and why the Internet has changed conspiracy theories. Combining the 'close reading' techniques of cultural studies and ethnography with the 'distant reading' possibilities offered by big data methods, the project will analyse the difference that the Internet has made to the production, aesthetics and consumption of conspiracy theories. The team brings together cultural studies researchers and a cutting-edge lab that is developing new methods for the analysis and data visualisation of online conspiracy culture. Using digital methods, we will first map out the scale and scope of contemporary conspiracy theory culture in both the mainstream and the 'deep' web. This will shed light on the forms of conspiracy theory that generate the most engagement; how they spread on particular platforms; the role of recommendation algorithms; and the identity, connectedness and political stance of the main creators of conspiracy content. The second strand of research will place the production and transmission of conspiracy theories on the Internet in historical perspective, comparing earlier moments of 'new media' transformation (such as radio), and tracing how conspiracy theories have changed as the Internet itself has evolved over the last half century. By examining the content moderation policies, this strand will also consider how various digital platforms encourage or hinder the exchange of conspiracy theories online. The third research strand will focus on the form and function of online conspiracism by focusing on its dominant images, metaphors and narratives. In particular we will consider whether the ease of creating links on websites tends to push conspiracy theories to more elaborate, hyper-connected forms. The fourth research strand will study how conspiracy theories are consumed and appropriated on the Internet. Where psychology has tried to identify the personality traits that attract people to conspiracy theories, our research will use an ethnographic approach to analyse online discussion fora and conduct interviews with conspiracy theorists to determine how their encounter with conspiracy theories helps forge individual and group identities, for better or worse. In the final strand we will also assess when online conspiracism turns harmful, and what, if anything, can be done about it. The main outcome of the project will be a definitive book that sets out the findings of the research. In collaboration with the Institute of Education and the charity Sense About Science, we will develop workshops and materials (a) to train school teachers how to deal with the problem of conspiracy theories in the classroom, including creating educational materials for use with young people and (b) to help scientists and science communicators address conspiracy theories about e.g. climate change and vaccinations. Working with the think tank Demos, we will hold a high-profile end-of-project event and produce a report for stakeholders.
