This book presents different approaches to disinformation based on original data from quantitative and qualitative studies conducted within CEDMO (Central European Digital Media Observatory). The linguistic and visual features of this type of communication are analyzed in the context of the discursive and genre framing of fake news. The authors discuss the psychological mechanisms of the reception of manipulated content, as well as the legal and political contexts of disinformation in Central Europe (Poland, the Czech Republic, Slovakia). The book presents the results of comparative research on attitudes to Covid-19 and the war in Ukraine, linking the two. The volume contains not only empirical studies, but also an elaborate proposal for a theoretical approach to manipulated content and a coherent methodological model that can be used to deepen scientific knowledge of this complex area of study.
