Academic attention towards the effectiveness of fact-checking often centres on how receptive people are to the correction of news. But many studies do not take into account audience expectations of fact-checking or their engagement with news generally in the context of a national media system or its political culture. Our study makes an intervention into debates about fact-checking by focussing on the effectiveness this type of journalism has with audiences who were attentive to the news in the UK’s media system during a key point in a major health crisis. Drawing on a six-week news diary study (N = 200) during the coronavirus pandemic, our study concluded that the UK’s impartial media ecology and public service ethos creates an environment where audiences are largely receptive to journalists’ fact-checking and countering misinformation. Yet our content analysis of television news (N = 1259) during the pandemic found most broadcasters did not regularly challenge or question the government’s decision-making. We argue that since audiences favoured robust forms of journalistic scrutiny, broadcasters could more prominently fact-check claims and question dubious statements without undermining trust in journalism. We recommend scholars should pay more attention to understanding the audience reception of fact-checking across different media and political systems.
