The Interfaced Subjective Reality Model: A Framework for Private Perception and Intersubjective Coherence

The Interfaced Subjective Reality Model (ISRM) proposes that all conscious agents inhabit wholly private experiential worlds, constructed from sensory inputs and cognitive processing. While traditional philosophy recognises the subjective nature of perception — from Kant’s distinction between phenomena and noumena, to Berkeley’s idealism and Hume’s bundle theory — ISRM adds a mechanism for intersubjective coherence: a shared “reality interface.” This substrate transmits universal rules (such as causal laws and physical constants), synchronised world-state data, and behavioural patterns for other entities. Interactions occur via locally rendered avatars derived from this shared feed, not through direct access to other minds. ISRM bridges philosophical scepticism, neuroscience’s internal model theory, and physics’ informational interpretations, offering a framework that accommodates quantum indeterminacy, cognitive diversity, and perceptual variance while maintaining causal consistency. Implications include the limits of objectivity, the impossibility of perfect experiential verification, and the potential for subtle divergence between individual renderings despite overall rule alignment.
