The Universal Connection Mental Model, also known as the interconnected thinking model, centers on the recognition that all things in the world are linked through various explicit and implicit, natural and human-made interactions, influences, and constraints. It emphasizes that entities, phenomena, processes, and their internal elements do not exist in isolation but are universally interconnected. Applying this model means that when solving problems, one should not only observe surface-level connections but also actively uncover the critical underlying links, examining the holistic system formed by these connections from a comprehensive and systemic perspective—ultimately enabling innovation or identifying optimal solutions.
