“…In the biggest research strand, scholars have focused on the patterns of news coverage, essentially evaluating the quality of media coverage across a broad set of indicators (Marcinkowski & Donk, 2012;Marquis et al, 2011) or focusing on one or few indicators, such as balance (e.g., Cushion & Lewis, 2017), the existence of issue frames instead of game frames (Dekavalla, 2018), dialogue (e.g., Hänggli, 2020), or topic diversity (e.g., Udris et al, 2016). While content analyses with core indicators of media quality have increasingly become complex and nuanced, they do not provide detailed insights on the quality of argumentation (one exception is Renwick & Lamb, 2013), a feature which is considered necessary for issue-focused referendum campaigns and threatened by politicians' "strategic lying" (Gaber & Fisher, 2021). For instance, Maia (2009) captured the number of arguments used in media texts but did not assess the validity or accuracy of arguments.…”
