Fuzzy-Logic for Sociology

This contribution introduces fuzzy-logic as a possibly new basis for sociology. After a general introduction to the basic principles of fuzzy-logic certain advantages are presented exemplarily, particularly for the empirical research considering as example the so called “qualitative-comparative analysis” (QCA), and for the sociological theory concerning Hartmut Esser’s theory of action. In sum, the application of fuzzy-logic promises sociology a more simple modelling of more complex facts than it has been possible so far. © 2005, VS Verlag für Sozialwissenschaften/Wiesbaden.
