Guided tours are a “perspicuous setting” (Garfinkel \& Wieder 1992) both for the study of asymmetries in professional contexts of interaction as well as for the analysis of how participants negotiate identities, categories and expertise. At first glance, the categorial distinction between “guide” and “guided” participants appears to be clear-cut. However, analyses of video recorded tours taking place in various sites show that the taken-for-granted authority, expertise and thus identity of the “guide” is repeatedly challenged by his or her co-participants. Based on conversation analytic methods, in this chapter we focus on sequences of interaction in which the participants compete for epistemic authority. We show how such competition emerges, how participants handle it, and how it is eventually solved.
