Social Networks and Social Movements: A Microstructural Approach to Differential Recruitment

Past examinations of differential recruitment to and the differential growth of social movements have typically sought explanation at a social psychological/motivational level of analysis. That focus has recently been called into question by scholars concerned with the process through which movement organizations expand their ranks and mobilize support for their causes. Yet, as Useem (1975) and Zald and McCarthy (1979) have noted, there has been little systematic research conducted on the details of the influence process. Drawing on data derived from a synthesis of existing research and two primary sources, this paper attempts to shed greater empirical and theoretical light on the movement recruitment process. The findings indicate that differential recruitment is not merely a function of dispositional susceptibility, but is strongly influenced by structural proximity, availability, and affective interaction with movement members. The findings also indicate that a movement organization's network attributes function as an important determinant of its recruitment strategies and growth.
