This monograph is the seventh in the Cognitive Cybernetics Technical Monograph Series, building on the foundational distinctions established in Cognition as a Control System, Content Is Not the Unit of Failure, Inference Regulation Over Time, Control Layers and Cognitive Motion, Why Intelligence Does Not Prevent Collapse, and The Difference Between Reasoning and Regulation. It introduces feedback as structural—the mechanism by which cognition becomes structure, not a corrective add-on applied after reasoning. The work defines a cognitive feedback loop as a closed regulatory cycle where inference produces an outcome, the outcome modifies control parameters, and modified control parameters shape the next inference, operating continuously often without explicit signaling. Four primary feedback channels are identified operating in parallel: outcome reinforcement (successful closure strengthens the pathway that led to it), termination reinforcement (early stopping conditions become more likely to trigger again), evaluation weighting (certain signals gain priority while others are suppressed), and navigation bias (previously traversed paths become preferred routes). Feedback effects are cumulative: each cycle slightly alters thresholds, shifts weighting, and reinforces dominance. Over time, small adjustments produce large structural changes, explaining gradual stabilization rather than abrupt failure. Stability emerges because reinforced paths require less control effort, familiar trajectories minimize processing cost, and deviation becomes increasingly expensive—stability is an emergent property of feedback, not a goal. Under sustained reinforcement, feedback loops can become self-sealing, producing reduced responsiveness to new signals, dominance of prior outcomes over current input, and resistance to reconfiguration. At this stage, feedback no longer adjusts cognition; it fixes it. Feedback does not require error to operate; correct outcomes can reinforce narrow pathways, rigid termination, and shallow exploration, producing systems that function well while losing adaptability. Observers often attribute feedback lock-in to stubbornness, bias, or unwillingness to change, but structurally the system is behaving correctly according to its reinforced control configuration. The issue is not resistance; it is reinforcement history. This pattern is invariant across human cognition, artificial systems, and hybrid environments—the mechanism depends on regulation, not substrate properties. The monograph closes with a boundary statement: feedback is not a response to cognition; it is the mechanism by which cognition becomes structure. To understand why cognitive systems stabilize, repeat, or resist change, one must analyze the feedback loops that regulate their motion.
