The metaphor of “repertoire” is increasingly used in the study of contention to convey the fact that people act collectively through a limited set of cultural routines. Yet despite its broad adoption, the term is loosely defined and rarely subject to empirical verification. This has led to unfruitful scholarly disputes, with most perspectives assuming that change in repertoires is independent from how actors perform them. Drawing a parallel between the dynamics of repertoire performance and jazz improvisation, I propose a pragmatist (...) definition of repertoires, understood as relational sets of collective practices that become routinized as habit-sets and become a baseline for innovation when actors face puzzling situations. I then provide a theoretical model for analyzing change in contentious repertoires, which relies on the study of the co-constitutive relation between tactical affordances, actors’ strategies and identities, and contexts. I illustrate this model with three secondary cases of unexpected tactical innovation. (shrink)

Drawing on models of the interaction order, we describe how planning is an inherently social activity. We argue that planning as a practice involves five core elements: mirroring, identifying, coordinating, timing, and surmounting. Specifically, planning depends on (1) a realization of likely responses of others, (2) a recognition of communal understandings, grounded in local cultures, (3) a commitment to collaborative engagements with allies, (4) an adjustment to temporal sequences involving the use of “in time” strategies and tactics, and (5) an (...) ability to overcome or avoid obstacles and blocking moves set by competitors and adversaries. Planning is evident in micro-, meso-, or macro-level domains. To demonstrate how planning is a social accomplishment, we analyze three distinct ethnographic sites: the world of competitive chess, dependent on the micro-interactions of two competitors; the meso-level process of homebuying, requiring the aid of real estate agents as allies; and macro-level structures in directing social movement activism in a contentious action field. Planning extends beyond cognitive achievement and is central to a sociology of the future. (shrink)
