Cybernetics is a wide-ranging field concerned with circular causal processes such as feedback. Norbert Wiener named the field after an example of circular causal feedback—that of steering a ship[note 1] where the helmsman adjusts their steering in response to the effect it is observed as having, enabling a steady course to be maintained amongst disturbances such as cross-winds or the tide.[1][2]

Cybernetics is concerned with circular causal processes however they are embodied,[3] including in ecological, technological, biological, cognitive and social systems and also in the context of practical activities such as designing, learning, managing, etc. Its transdisciplinary[4] character has meant that cybernetics intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.
