Transparency as a key element of data journalism Perceptions of Brazilian professionals

In recent years, especially because of disinformation, transparency has been an important part of journalists' work. Transparent conduct involves opening methods and procedures of reporting. It means, overall, showing the audience how the information was obtained and verified until being published. This study aims to unravel Brazilian data journalists' perceptions of transparency. In order to do so, it presents the results of a survey with 36 professionals in 2019. Most of them are data journalists that work in newsrooms for more than ten years. A significant part of the respondents believes that transparency must be shown every day to the readers. Among the main reasons to rely on transparency as an important value in their practice is the necessity to increase credibility in journalism and combat disinformation. Furthermore, this research suggests that transparency seems to be connected to objectivity and journalists' ethics, but not necessarily to the news outlets' rules.
