The Lehmann Cycle – Theoretical Architecture of Reality Processing

The Lehmann Cycle introduces a universal four-stage architecture of reality processing. The model describes how expectations are generated, how real-world feedback is integrated, how deviations are evaluated, and how decisions are updated. The architecture is structural, non-normative, diagnosis-independent, and culturally stable. It closes a theoretical gap between predictive approaches in cognitive science and practical models of orientation by defining a minimal, repeatable, and universally observable cycle of reality-aligned decision formation. The Lehmann Cycle provides a structural description of reality processing without prescribing goals, behaviours, or interventions.
