The UPC–QM Bridge: A Structural Account of Political Disagreement

This paper develops a structural account of political disagreement using the Universal Principle of Collapse (UPC) and its correspondence to quantum measurement. In this framework, political interpretation is modeled as an operator chain acting on a high‑density potential domain (PO) containing economic, moral, identity‑linked, and historical variables. Divergence arises in the early operators, specifically salience gradients and articulation bases, which determine how the shared external political field is partitioned and ordered prior to explicit reasoning. When two observers articulate their respective observer‑relative POs in non‑commuting bases, their collapse outcomes become internally coherent yet mutually incompatible. This mechanism explains the persistence and stability of political disagreement without appealing to irrationality, misinformation, or value conflict. The UPC–QM Bridge provides a formal structure for analyzing how incompatible interpretations emerge from shared information, offering a mechanistic foundation for future work on political cognition and the conditions under which partial operator alignment may be possible.
