“…Therefore, it is of utmost importance to get access to real-world data from tech-companies such as Facebook to answer such questions [but see problems with the recently launched “Social Science One”-initiative; (Ledford, 2019 ; Hegelich, 2020 )]. Alternatively, when it is not possible to web-scrape data without intruding into user privacy, one could invest more research energy and funding into simulations of social media platforms, where different constellations of in-built features are tested for a variety of research questions targeting usage time, well-being (Brooks, 2015 ; Duradoni et al, 2020 ) and effects of filter-bubbles on radicalization (Zuiderveen Borgesius et al, 2016 ), among others.
