Carsten Q. Schneider is Associate Professor in the Department of Political Science and Founding Director of the Center for the Study of Imperfections in Democracies at Central European University, Hungary. Claudius Wagemann is Lecturer in the Doctoral Program in Political Science at the Istituto Italiano di Scienze Umane (SUM), Florence.

'We have long needed a volume that comprehensively, clearly, and systematically covers Boolean and fuzzy set methodologies. Schneider and Wagemann have filled this need with their book, and it will certainly play a central role in guiding research and teaching.' Gary Goertz, University of Arizona
