"Breaking Agenda Setting Boundaries: A Multi-Dimensional Approach to Understanding Salience of Gun Control in the Polarized Public Sphere

If more than 50 years of agenda-setting theory in Communication Sciences have proven its inf luence and vitality, it is safe to say that continuous theoretical and methodological deepening has increasingly emphasized the subtleties behind an overarching theory.If the initial postulation of the agenda-setting theory (McCombs & Shaw, 1972) benefited from undeniable clarity and simplicity, the same must be more prudently said today, given the accumulated knowledge and growing complexity of studying the power of mediation and the more than five decades of scientific evolution.It is also true that the theoretical and methodological dimensions have since significantly broadened, and with them, the methodological demands, with recurrent reminders of the need to prove a causal relationship rather than a mere correlation (cf.McCombs & Shaw, 1972: 184).However, understanding agenda-setting as a theoretical instrument for predicting thematic salience is less common.Vargo and Minooie's new article, which delves into the predictors of the thematic relevance of arms control in the United States of America, is a compelling addition to the field, whose approach and findings reinforce the urgency of its reading and invite further exploration and open-minded discussion.
