概要	Broken windows assessment is the systematic measurement of physical and social disorder — graffiti, litter, broken windows, public drinking, loitering — tied to the hypothesis that visible disorder signals that no one is in control and thereby invites further crime. Stated by Wilson and Kelling in 1982 and put on a rigorous empirical footing by Sampson and Raudenbush's systematic social observation, it turns the metaphor of an unrepaired broken window into a quantified, reliable neighborhood scale.	The collective efficacy scale measures a neighborhood's shared capacity to maintain order: the combination of social cohesion and mutual trust among residents with their shared willingness to intervene for the common good. Introduced by Sampson, Raudenbush, and Earls in their landmark 1997 Science study, it operationalizes a reformulation of social disorganization theory and is constructed with ecometric methods that aggregate individual survey responses into reliable neighborhood-level scores.
