This work presents the C.O.R.D.Y.C.E.P.S (Cognitive Override & Reverse Deconstruction of Your Conditioned Emotional Programs & Suppression) model — a theory of systemic cognitive hijacking by a parasitic program functioning simultaneously as a biological agent (Cordyceps) and a self-learning social neural network. Unlike traditional approaches that treat psychological trauma as individual pathology, this model reveals a universal programming mechanism where the authentic self remains intact but is effectively controlled by an external system. The model also introduces a reverse deconstruction method designed to expose the parasitic structure and restore cognitive autonomy. The concept bridges psychology, philosophy of consciousness, social neuroarchitecture, and informational parasitism theory, offering new insights into chronic destructive states and providing a framework for dismantling them.
