Cybernetics is the transdisciplinary study of circular causal processes such as feedback and recursion, where the outcomes of actions return as inputs for subsequent actions. It is concerned with general principles that are relevant across multiple contexts, including engineering, ecological, economic, biological, cognitive and social systems and also in practical activities such as designing, learning, and managing. Cybernetics' transdisciplinary character means that it intersects with a number of other fields, resulting in a wide influence and diverse interpretations.
