Accuracy is a central norm in journalism and at the heart of the journalistic practice. As a norm, accuracy developed out of objectivity, and has therefore an Anglo-American origin. Nevertheless, the commitment to the rule of getting it right is shared among journalists across different journalistic cultures. The history of accuracy is closely related to other central concepts in journalism like truthfulness, factuality and credibility, because it raises epistemological questions of whether and how journalism is capable of depicting reality accurately, truthfully and based on fact. Accuracy plays a particularly important role with regard to the factuality of the journalistic discourse, as it forces journalists not only to ground their reporting on facts, but to check whether presented facts are true or not—which is reflected both in the description of the journalistic profession as the discipline of verification as well as the central relevance of accuracy for instruments of media self-regulation like press councils and codes of ethics. Accuracy is an important standard to determine the quality of the news reporting. In fact, many studies, most of them carried out Western democracies, have investigated the accuracy of journalistic reporting based on the number of errors that sources mentioned in the articles perceived. As journalism moved online and the immediacy of the news cycle requested a faster pace of publication, news outlets often adopted the strategy to publish first and to verify second, although research has shown that the accuracy of journalistic reporting and trustfulness are related. Especially in the current debate on disinformation, many online fact-checking and verification services have thus seen a global rise of attention and importance.
