Opening up terrorism talk: the sequential and categorical production of discursive power within the call openings of a talk radio broadcast

The current research undertakes a combined conversation analysis (CA)/membership categorisation analysis (MCA) approach to analyse the unfolding moral business of 'talk radio' discourse, and situates this analysis within a critical discourse studies framework. In a case study analysis of a talk radio broadcast on the topic of terrorism, the sequencing and membership categorisation work that is accomplished during the call openings of its contributors is examined. Local manifestations of discursive power allied to the 'host' role are identified, along with the data-driven distinction of 'lay' and 'elite' callers. The empowering versus disempowering consequences of sequential turn allocation and identity categorisation are explored, leading to some reflections on security versus human rights advocacy within terrorism talk. The contribution of this research to two research enterprises is then outlined. First, we highlight the benefit that a combined CA/MCA approach, which foregrounds powerplay, offers to analysis of talk-in-interaction. Following this, we underline how placing such a micro-level spotlight on the seemingly mundane details of talk in context can offer valuable insights for critical terrorism studies.
