A term used to denote an extreme degree of professional deformation, characterized by the limitation of thinking within the framework of professional activity. It manifests itself in the inability to go beyond professional stereotypes, a decrease in the general cultural level, and social disadaptation. According to researchers of professional deformations, professional cretinism is the result of long-term exposure to monotonous, highly specialized activity. This condition requires preventive measures to expand horizons, develop universal competencies, and change activities.
