At the time of the COVID-19 pandemic, scientific expertise was and is more in demand than perhaps ever before. Scientific “experts” serve as an important source of information for journalists and for society. Our study analyzes, which experts get a chance to speak in German news coverage of COVID-19 compared to other pandemics, how diverse the spectrum of selected experts is and how their scientific expertise is to be assessed. Our findings show that the COVID-19 coverage is dominated by actors from the political executive and less than in previous pandemics by scientific experts. In addition, the coronavirus debate is characterized by a greater diversity of expert voices and the journalistic selection of scientific experts is biased in favor of those who have a high scientific expertise. On average, COVID-19 coverage seems to be biased more pronouncedly in favor of reputable scientific experts compared to previous debates on pandemics.

At the time of the corona pandemic, the population has a great need for information. (Mass) Media try to provide the concerned citizens with answers to their pressing questions with the help of scientific actors and their expert knowledge. Scientific experts serve as an important source of information for journalists and for society. Therefore, it is of particular relevance to examine, which scientific actors are discussing scientific issues related to the Covid-19 pandemic publicly via media coverage. Of particular interest is a look at the scientific expertise of the so-called experts, because the quality of the available information stands and falls with it. Our study describes the journalistic selection of scientific experts in German news coverage on Covid-19 compared to other pandemics. We analyze, which experts get a chance to speak in media coverage, how diverse the spectrum of selected experts is and how their scientific expertise is to be assessed. Our findings show that the Covid-19 coverage is dominated by actors from the political executive and less than in previous pandemics by scientific experts. Further, the Corona debate is characterised by a greater diversity of expert voices than the previous pandemic debates and therefore less concentrated on a few individual scientists only. Further, the journalistic selection of scientific experts is biased in favour of those who have a high scientific expertise. On average, media coverage on the Covid-19 pandemic makes references to more reputable and acknowledged scientific experts compared to earlier pandemics.
