# Cybernetic Control Cybernetic control is the regulation of a system through observation, comparison, feedback, and adjustment. A controller acts, measures the resulting state, interprets the difference from a goal or constraint, and modifies future action. In communication systems, reach or engagement is only a signal. Governing values determine whether an adjustment is acceptable. Without explicit constraints, feedback can optimize attention while degrading truth, trust, dignity, or long-term resilience.
