Critical juncture theory
Critical juncture theory focuses on critical junctures, i.e., large, rapid, discontinuous changes, and the long-term causal effect or historical legacy of these changes. Critical junctures are turning points that alter the course of evolution of some entity (e.g., a species, a society). Critical juncture theory seeks to explain both (1) the historical origin and maintenance of social order, and (2) the occurrence of social change through sudden, big leaps.Critical juncture theory is not a general theory of social order and change. It emphasizes one kind of cause (involving a big, discontinuous change) and kind of effect (a persistent effect). Yet, it challenges some common assumptions in many approaches and theories in the social sciences.
