Abstract
Methodological critique of the sociological theory "spontaneous cooperation" to explain the revolution in Germany in 1989. This approach represented the german sociologists Dieter Opp and Detlef Pollack.
The author reconstructs the two statements. Opp's approach is logically inconsistent. This approach is also unfit for scientific prediction, but Opp says the possibility of prediction is a necessary criterion for a scientific theory.
Pollack's systemtheoretical approach ignores the really existing organized resistance of the subversive groups in Leipzig, for example the "Working group for human rights" or the "Working group for Justice".
Miracle or surprise chance are scientifically anacceptable models to explain a revolution.
Both economically and politically offered the capitalist welfare state more for the workers than the socialism. So people noticed socialism as a system with more work for less prosperity and without civil rights, as a system of "exploitation by inefficiency" (Elsenhans).
The author describes the revolution as a result of very effective collaboration between people, who willing to take risks and wanted to emigrate from the GDR to West, and the subversive groups, that could organize the revolutionary resistance. - This is a possible interpretation of the revolution from the interaction of transition-theory and voice-and-exit-theory (Hirschman).
