In this paper we extend the analysis of framing processes in relation to social movements by exploring the problem of non-resonance in more detail than it has been examined heretofore. The problem of non-resonance is of relevance not only to social movement scholars but also to movement practitioners or activists who often devote a significant portion of their time and energy trying to mobilize constituents, convert bystanders, and demobilize antagonists, but who often fail to reap the benefits of these efforts. This failure is attributable in part, we argue, to the non-resonance of their proffered framings. Accordingly, in this paper we seek to advance understanding of non-resonant frames ? that is, frames that do not appear to strike a responsive chord with presumed constituents or targets even though they may have done so sometime in the past, or even though its proponents or sponsoring activists think the cause or issue warrants mobilization. We ask: Why do collective action frames sometimes fall on deaf ears or fail to help crystallize support for a cause and move adherents, metaphorically, from the balcony to the barricades? Previously, Benford and Snow (2000; Snow and Benford 1988) suggested that two sets of interacting factors account for variation in the degree of frame resonance: the credibility of the proffered framing, as determined by frame consistency, empirical credibility, and the credibility of its articulators or proponents; and its salience to targets of mobilization, as affected by matters of centrality, experiential commensurability, and narrative fidelity. Here we draw on this work but want to be less abstract and more concrete and pragmatic by suggesting four sets of framing problems that confront movements of all stripes and that are relevant to understanding the problem of non-resonance. The problems identified and elaborated include: the problem of misalignment (focusing on perpetrators or responsible agents for some troublesome event or state before victimage is firmly established); the problem of scope (failing to adapt the scope or reach of a frame to the changing vicissitudes of the context in which movement is embedded); the problem of exhaustion (continuing to frame events and issues in terms of tired, over-used, taken-for-granted frames); and the problem of relevance (change in flow of events quickly rendering current framings irrelevant or off-target). Illustrative data are derived from the studies of other movement scholars, as well as from our own research on a series of anti-war and support-our-troops protests that occurred over a six week period in the greater Los Angeles area during the winter/spring of 2003.
