The Index of Evidence: speculative methodologies in response to the post-truth era

The past year has shown that even the fundamental idea of ‘evidence’ – in health contexts, but also more broadly - is coming under increasing strain. This open letter argues that the current crises of evidence and knowledge in which we find ourselves demands new speculative methodologies. It introduces the Index of Evidence – a Beacon Project funded by Exeter University’s Wellcome Centre for Cultures and Environments of Health - as one example of such a methodology, outlining its theoretical foundations and process. The key innovation of this project is to rethink the form and presentation that research can take. Using the conceptual and material affordances of the index, it merges the creative and critical in ways that aim to make an important contribution to more inter-connected, theoretically sophisticated thinking around evidence.
