Critical theory has rarely articulated an agenda for social change linking theory to practice. This paper provides several examples of “critical theory in practice” and focuses specifically on Fay’s Critical Social Science (CSS) model. The methods of conflict transformation are then applied to CSS in order to accomplish two goals. First, political conflicts resulting from decision making can be used to transform both individuals and systems. Second, CSS more adequately accounts for some of the non-rational aspects of human nature, such as our resistance to change, thus improving its catalytic validity as a critical social theory. Together, the processes of CSS and conflict transformation provide a framework for enhancing the potential for citizen governance.
