Abstract: | Explanations of why people participate in social movements are usually ad hoc combinations of ideology, social support, and ecological factors. This survey of Californians active in the nuclear freeze movement found that rather than structural isolation, as suggested by collective behavior tradition, the participants displayed links to Democratic Party organizations and the previous anti-Vietnam War movement. At least some social movements may become institutionalized to the degree that paradigms from areas such as political sociology of institutions are needed. Social movements may have evolved beyond their earlier collective behavior origins. |
