evidence: The UK’s Full Fact offers a distinctive example of an independent, single-purpose fact-checking outlet positioned as a think tank. Founded in 2010, the organisation investigates claims by both politicians and the news media and is unusual in placing a heavy emphasis on actively seeking corrections. As its mission statement explains, ‘we … push for corrections where necessary, and work with government departments and research institutions to improve the quality and communication of information at source’. The organisation has also provided testimony to government inquiries relating to accuracy in the media. These interventions may count as a narrow kind of campaigning, but its mission requires Full Fact to strictly separate itself from both news outlets and political groups and causes, even forbidding staff from expressing political views. According to director Will Moy, the site relies on some journalists in its fact-checking work but increasingly seeks researchers with domain expertise in the areas they cover.
