It has been suggested that transparency will change the way journalism is being produced as well as increase its credibility. However, little research has been conducted to assess the connection between transparency and credibility. This study utilizes an experimental setting with 1320 respondents to measure what impact transparency has on source and message credibility from a user perspective. The results reveal an almost total absence of any transparency effect on either source or message credibility, although some small significant effects could be observed primarily regarding internal hyperlinks, comments and contextual information. Although further research is needed in this area, the study suggests that transparency does not affect the credibility of journalism in the eyes of the contemporary audience and thus has limited appeal as a new norm in journalism.
