Intrusion and Collapse: How Deferred Contact Becomes Debt in Psyche and Society

Structural Intelligence (SI) distinguishes coherence from contact and treats collapse as forced contact: the moment reality becomes non-optional because substitution can no longer be sustained. This paper develops a bridge thesis linking individual intrusion phenomena to collapse dynamics across personal and societal scales. Intrusion is defined as occupancy of steering by a competing loop and is operationalized through time-local occupancy (λt) and time-averaged load (I). The paper introduces Structural Debt (Ds) as the conserved remainder of refused contact created by substitution and adds a maintenance inflation principle: the cost of suppressing returning contact rises over time, accelerating collapse. Jungian complex psychology is translated into these terms by treating complexes as intrusion-capable structures and the shadow as the ledger of refused contact. The same mechanics scale to societies through network viscosity (V) and epistemic exchange rate (Ex), explaining how environments that make coherence cheaper than verification select for theater, scapegoating, and collapse. The paper closes with diagnostics, falsifiers, and falsifiable predictions, presenting a conserved collapse pipeline within the SI framework.
