# Cognitive Security Cognitive security is the protection of the conditions under which people and institutions perceive, interpret, deliberate, and decide. It addresses manipulation of attention, trust, identity, provenance, emotional response, and shared reality—not by attempting to control thought, but by protecting agency and the integrity of the information environment. Practical measures include provenance, media literacy, anomaly detection, trusted communication, cognitive inoculation, channel integrity, contestable analysis, and resilient public institutions. The defensive objective is not enforced agreement. It is preserving a person's ability to evaluate claims without covert distortion or manufactured epistemic exhaustion.
