Tiered Social Recursion: A Functional Architecture for the Evolution of Consciousness

We introduce the Tiered Social Recursion (TSR) framework, bridging the gap between functional neurobiology and subjective experience by framing consciousness as a tiered evolutionary adaptation of internal world modeling. TSR identifies distinct computational leaps from basal reactive awareness to meta-aware social recursion, driven by social fitness demands. Aligning with recent adversarial tests of consciousness theories, we propose that qualia emerge from the recursive modeling of “outer self” in the minds of conspecifics. By utilizing taxonomic benchmarks from Cyanobacteria to Homo, we illustrate the hierarchy’s biological grounding. The proposed operationalization comprises a hierarchical sensory Parser, Ontological Engine integrated with Long-term Memory, an environmental-grounding Δ-unit, and Short-term Memory closing the autoregressive loop; this generative-perception architecture is grounded in neuroanatomy and disorders of self-awareness, as exemplified by Cotard’s syndrome. Considering synthetic consciousness, TSR argues that without physical embodiment, artificial systems cannot internalize the social recursion necessary for biological-like awareness.
