Knowing Humans


How does science shape what humans know, and what we know humans to be?

The Covid-19 crisis has thrown a spotlight onto these questions, and the life-and-death stakes attached to human knowledge. For example, what role did scientific knowledge play in policy decisions during the pandemic, and how did that knowledge influence decision-makers’ perceptions of ‘the public’?

Our work addresses such questions, revealing with the assumptions and imaginaries that underpin our knowledge about the world, who contributes to that knowledge, and who or what remains excluded. Engaging with these questions sheds new light on some of modern democracies’ most urgent issues, such as what determines whether knowledge is trustworthy, what kinds of knowledge are needed to address social and environmental crises, and whether we are really seeing the rise of ‘post-truth’ societies.

How are digital platforms changing experts and expertise?

Traditional forms of expertise appear in crisis. Digital platforms such as YouTube, Wikipedia and Zhihu increasingly shape the knowledge and expertise that constitute the infrastructure of modern knowledge-based democracies. Techno-optimism about the democratisation of knowledge has given way to dismay that the internet has eroded the shared truths that enable rational discourse. Digital platforms’ business models incentivise audience over accuracy, with publics increasingly concerned about the resulting online misinformation. Meanwhile, a new wave of right-wing ‘populist’ politicians in the US, Brazil and elsewhere have come to power by fostering an anti-expert culture. Yet within this bleak picture, new kinds of experts and expertise, particular to digital platforms, are emerging in domains as diverse as finance, science and culture. This project challenges existing theories of expertise and democracy by thinking through the impacts of the technological structures and political contexts within which knowledge is now created, exchanged and, sometimes, resisted.

Making climate social

Social media has transformed the communication of climate change, challenging established sources of scientific knowledge and providing new opportunities to rethink and reframe the ways we talk about the issue. This project, funded by the Economic and Social Research Council, explores how our understanding of climate change has evolved across different social media platforms, and what this means for the future of climate change communication.

Science, politics and trust in the Covid-19 crisis

In this emerging project, we study the troubled boundary between science and politics during the pandemic, and how the issue of trust was integral to the presentation and production of knowledge. The project investigates whether a lack of trust in official sources of knowledge contributed to the emergence of alternative sources of expertise as diverse as a resurgent blogosphere and Independent SAGE.

Picturing emergency

Images are an increasingly important means by which societies collectively imagine political issues. Yet images remain under-researched in comparison to speech and text. This project seeks to fill this gap, exploring how people and organisations use images to communicate the idea of ‘emergency’ within the examples of Covid-19 and climate change. We use an innovative mix of digital and interpretive methods, in collaboration with information designers, to research the production and reproduction of images within and between different digital platforms.

The use of consensus in evidence-based policy

Scientific consensus is central to the production of climate change knowledge (eg IPCC) and climate communication. What lessons can other science-led policy areas learn from this, and are there plausible alternatives to consensus as a basis for policy? What are the advantages of seeking consensus on the knowledge that informs decision-making. Who in society might be disadvantaged by such approaches? In short, where and when should we seek agreement, or be happy to live with difference?
