"Very Large Online Platforms (VLOPs) such as Instagram, TikTok, and YouTube wield substantial influence over digital information flows using sophisticated algorithmic recommender systems (RS). As these systems curate personalized content, concerns have emerged about their propensity to amplify polar ... izing or inappropriate content, spread misinformation, and infringe on users’ privacy. To address these concerns, the European Union (EU) has recently introduced a new regulatory framework through the Digital Services Act (DSA). These proposed policies are designed to bolster user agency by offering contestability mechanisms against personalized RS. As their effectiveness ultimately requires individual users to take specific actions, this empirical study investigates users’ intention to contest personalized RS. The results of a pre-registered survey across six countries – Brazil, Germany, Japan, South Korea, the UK, and the USA –involving 6,217 respondents yield key insights: (1) Approximately 20% of users would opt out of using personalized RS, (2) the intention for algorithmic contestation is associated with individual characteristics such as users’ attitudes towards and awareness of personalized RS as well as their privacy concerns, (3) German respondents are particularly inclined to contest personalized RS. We conclude that amending Art. 38 of the DSA may contribute to leveraging its effectiveness in fostering accessible user contestation and algorithmic transparency." (Abstract) more

"Exogenous shocks like the COVID-19 pandemic unleashes multiple fundamental questions about society beyond public health. Based on the classical concept of ‘need for orientation’ and the literature on the role of the media in times of crisis, we investigate to what extent the COVID-19 pandemic a ... ffected news consumption in comparative perspective. Based on a two-wave panel survey in 17 mostly European countries, our study targets the role of both legacy news brands (TV, radio, newspapers) and so-called contemporary news media (Internet-based and social media) during this global health crisis. Our results show an overall rise of news use across countries, but only for some types of news media. We find an increase of TV news consumption, and a higher reliance on social media and the Internet for news and information. This indicates that in times of crises and an unusually strong need for orientation, people mainly turn to news sources that are easily available and offer a more immediate coverage. Furthermore, we find the rise in news use to be mainly present among those who already have a higher level of trust in legacy media and among people that were more concerned about the impact of the pandemic."
