Cybernetics

Roles: controller, sensor, signal, feedback, set-point, error, actuator, delay

The science of communication and control in animals and machines, founded by Norbert Wiener in 1948. Cybernetics studies how systems regulate themselves through feedback — sensors detect deviation from a goal, and controllers adjust behavior to reduce the error. As a source domain, cybernetics provides the vocabulary of feedback loops, set-points, error signals, and adaptive control that has been mapped onto everything from organizational management to psychotherapy. The frame’s power lies in its abstraction: the same feedback diagram describes a thermostat, an immune response, and a performance review process.
