This article is dedicated to investigating rationality as one of the key characteristics of Michel Foucault's concept of governmentality and to related contradictions inside and outside Foucauldian theory. Using risk theory, the author explores the possibility of the existence of multiple rationalities in governmentalities and offers a solution to the contradiction within Foucauldian theory. The article focuses on the question of how it is possible to resolve both methodological, practical, as well as theoretical, contradictions in the theory of governmentality, keeping (...) its main characteristics, such as population-centeredness, intact. The author concludes that diversification is more effective within the framework of multiple rationalities, which is most consistent with the understanding of the governmentality of the population as a goal, as a mechanism of risk management. The article makes a significant contribution to the understanding of the relationship between rationality and irrationality in the theory of governmentality, putting forward new ideas for the research and development of effective forms of public administration. The author also suggests ways to solve the paradox of regulated freedom, which has practical implications for modern methods of governance and regulation in society. This more detailed analysis clarifies how Foucault's concept of governmentality can be applied in a contemporary context, and how the limitations of rationality can be overcome to achieve more flexible and adaptive forms of governance.
