Which theory classification is considered the most abstract?

Grand theory is considered the most abstract classification of theory in the context of social sciences and related fields. Grand theories aim to provide a comprehensive framework for understanding large-scale phenomena and are often not directly testable in empirical terms. They seek to explain broad concepts that encompass various aspects of human experience or societal structures, such as power dynamics, social change, or cultural systems.

This level of abstraction differentiates grand theories from middle-range theories, which focus on more specific, limited aspects and can be applied to particular situations or phenomena. Practical theory, on the other hand, tends to emphasize application in real-world scenarios and often includes specific guidelines for practice, making it less abstract. Operational theories are usually formulated to facilitate measurement and testing within empirical research, indicating a concrete focus rather than abstract reasoning.

Thus, when considering the dimensions of abstraction in theory classification, grand theory stands out as it engages with overarching ideas and universal principles, forming the foundation for how we understand complex realities.
