Collective Efficacy

Collective efficacy refers to the shared belief and capacity of members of a community to work together, intervene for the common good, and achieve collective goals, particularly through informal social control. The term was developed in criminology by Robert Sampson, Stephen Raudenbush, and Felton Earls in their Chicago neighborhood study, which found that social cohesion combined with willingness to intervene on behalf of neighbors predicted lower rates of violence, even after accounting for disadvantage. It draws on Albert Bandura’s psychological concept of self-efficacy, extended to groups, and on social disorganization theory associated with Clifford Shaw and Henry McKay, who linked crime to weak community ties in poor, unstable neighborhoods. Robert Putnam’s work on social capital and trust and James Coleman’s analysis of social closure provide related frameworks. Collective efficacy has also been applied to health, education, disaster resilience, and political mobilization. Critics argue that measurements may overlook structural inequality and the role of policing and segregation, and that high efficacy in privileged areas can exclude outsiders. Collective efficacy remains central to research on neighborhood effects, crime, community organization, and urban inequality.
