The study relies on the news value theory and analyzes observations of users’ news attention and selective exposure on Google News via eye tracking (N = 47 participants, N = 751 news items). Alongside direct effects, the study also examines indirect effects of news factors on users’ news selection processes via media cues of news items on the news aggregator website (e.g., picture, position, and recency). Prior knowledge and search behavior influenced search outcomes.ĭo journalistic relevance criteria still matter in digital news environments where news is selected and aggregated by algorithms? This article investigates how news factors (e.g., conflict, power elite) influence users’ news attention and selective exposure on the news aggregator website Google News. Moreover, prior knowledge and involvement affected users’ browsing behavior. Results indicate that participants looking for specific information about CRISPR searched shorter, visited fewer Wikipedia pages, and followed shorter and more straightforward search paths than participants looking for general information about genetic engineering. An observational study was conducted in which 67 participants searched for general information about genetic engineering and specific information about CRISPR. By means of eye tracking and survey data, this study investigates how users find information about genetic engineering and CRISPR on Wikipedia and what influences search behaviors and outcomes. But research on search, selection, and reception processes on Wikipedia is scarce. Wikipedia has been shown to be an important source of information about scientific topics. CRISPR/Cas-based genome editing is a monumental leap in genetic engineering with considerable societal implications – but it is a complex procedure that is difficult to understand for non-scientists.
