Science and health communication have recently increased in importance, and not only because of crises such as anthropogenic climate change and the COVID-19 pandemic. Societies in general are growing more complex, and increasingly rely on scientific knowledge (Kohring, Vertrauen in Journalismus: Theorie und Empirie [Trust in journalism: Theory and empiricism]. UVK Verlagsgesellschaft, 2004; Luhmann, Vertrauen: Ein Mechanismus der Reduktion sozialer Komplexität [Trust: A mechanism for reducing social complexity]. UVK Verlagsgesellschaft, 2014; Summ & Volpers, What’s science? Where’s science? Science journalism in German print media. Public Understanding of Science, 25(7), 775–790. https://doi.org/10.1177/0963662515583419, 2016; Weingart, Wissenschaftskommunikation unter digitalen Bedingungen: Funktionen, Akteure und Probleme des Vertrauens [The integration function of the mass media: Conceptual history, models, operationalization]. In P. Weingart, H. Wormer, A. Wenninger, & R. F. Hüttl (Eds.), Perspektiven der Wissenschaftskommunikation im digitalen Zeitalter (pp. 31–59). Velbrück Wissenschaft, 2017), which goes hand in hand with the importance of public trust in science. Within this complex setting, science and health journalists are important actors who need to provide public audiences with reliable and solid information—especially during crises. However, in the current digital age, the functions of science and health journalism for society are challenged (Fahy & Nisbet, The science journalist online: Shifting roles and emerging practices. Journalism 12(7), 778–793. https://doi.org/10.1177/1464884911412697, 2011), particularly because scientific information reaches public audiences via a variety of (digital) media outlets, where journalistic and non-journalistic actors compete for attention (European Commission, Eurobarometer: European citizens’ knowledge and attitudes towards science and technology. https://europa.eu/eurobarometer/surveys/detail/2237, 2021; Metag & Schäfer, Wissenschaftsbarometer Schweiz 2016 [Science Barometer Switzerland 2016]. www.wissenschaftsbarometer.de, 2016; National Science Board, Science & engineering indicators 2018. National Science Foundation. https://www.nsf.gov/statistics/2018/nsb20181/assets/nsb20181.pdf, 2018). Thus, for public audiences, the question of whom and which information to trust becomes ever more important.
