Within the framework of the much-used framing theory, cultural resonance is supposed to explain how and why ideas are successful, when they are based on cultural themes or widely shared knowledge between people inhabiting a cultural space. This research contributes to the framing theory and resonance processes, by systematically conceptualizing the dimensions of cultural resonance and moving the concept beyond its metaphor state. The goal is to provide an operational definition of cultural resonance for frame analyses. To identify what types of cultural devices (e.g., values or patterned ways of speaking) were used by political actors in the Covid-19 vaccination debate, 449 Facebook posts of main political parties, their leaders and governmental Facebook accounts from Germany and Romania were collected through Facepager. The vaccination debate (time to vaccine approval in EU and the debate following it: Dec 2020 – Jan 2021) was chosen since we can observe competing strategies of meaning-making only when interpretations of events are contested. Linguistic discourse analysis combined with membership categorization analysis provided a productive analytical strategy with suitable tools for capturing meaning beyond manifest textual elements - e.g., presuppositions that refer to the necessary assumptions for rendering a message meaningful. Preliminary results show two dimensions of cultural resonance: 1) the mainstream vs radical character of cultural devices, which refers to how widely shared and accepted a cultural value or symbol is with the respective cultural space; 2) the communication style which ranges from factual, objective discourse to figurative narratives.
