Fears over ‘fake news’, targeted disinformation, and the rise of post-truth politics have met with a central mainstream solution: ‘fact-checking’. Fact-checking is featuring prominently in coverage of the 2019 UK General Election. ITV News, for instance, will use FullFact.org to analyse the claims made by Boris Johnson and Jeremy Corbyn in their forthcoming leadership debate, with the aim of better informing their viewers by exposing misleading statements.

This reflects the wider embrace of fact-checking as a panacea against the rise of anti-expert politics. It has been employed in coverage of US presidential and primary debates, as well as the parliamentary theatre of Brexit. Third party fact-checking organisations have also been championed by social media companies in response to demands by regulators and legislatures that they take responsibility for the content circulated on their platforms. Indeed the use of ‘independent’ fact-checkers to flag content was highlighted by Mark Zuckerberg, during his various appearances before Congress, in defence of Facebook’s practices.

However, the concept of fact-checking frames the problems of post-truth politics in narrowly positivist terms – as reducible to a lack of information (‘facts’), leading to sub-optimally rational decision-making by electorates. It has not been underpinned by a sophisticated account of the epistemic conditions for the exercise of democratic citizenship. Fact-checking occupies an increasingly central place in our political culture, but the justification for it remains largely implicit and untheorized.
