The Four-Model Theory of Consciousness: A Simulation-Based Framework Unifying the Hard Problem, Binding, and Altered States

Abstract

The science of consciousness remains in a pre-paradigm state, with no theory simultaneously satisfying the eight core requirements a complete theory must meet: the Hard Problem, the Explanatory Gap, the Boundary Problem, the Structure of Experience, Unity and Binding, Combination and Emergence, the Causal Role, and the Meta-Problem. This paper presents the Four-Model Theory, in which consciousness is constituted by real-time self-simulation across four nested models arranged along two axes - scope (world vs. self) and mode (implicit vs. explicit). The implicit models (Implicit World Model, Implicit Self Model) are substrate-level, learned, and non-conscious. The explicit models (Explicit World Model, Explicit Self Model) are virtual, transient, and phenomenal - they are the simulation in which experience occurs. The theory’s central claim is that qualia are constitutive properties of the computational level - digital constructs that exist at the level of the running computation but are incoherent at the substrate level, just as a spreadsheet cell’s value is incoherent at the transistor level. This dissolves the Hard Problem by revealing a category error - a level confusion that seeks phenomenal properties at the substrate level where they categorically do not exist. Self-referential closure explains why this specific computational process has experience when a weather simulation does not: the system’s model includes a model of itself, collapsing the inside/outside distinction and making experience constitutive rather than additional. Combined with a criticality requirement (the substrate must operate at the edge of chaos), the theory derives diverse phenomena from five principles: criticality, virtual qualia, a redirectable Explicit Self Model, variable implicit-explicit permeability, and virtual model forking. These principles unify psychedelic phenomenology, anesthetic mechanisms, dream states, split-brain phenomena, dissociative identity disorder, and animal consciousness. A systematic comparison shows the theory addresses all eight requirements. Unusually for a consciousness theory, the framework has substantial empirical grounding: five claims that follow from its core axioms - established in 2015 - have since been independently confirmed by research groups with no connection to the theory, including the anesthetic-criticality convergence (Casali et al., 2013; Hengen and Shew, 2025; Algom and Shriki, 2026), sleep-dependent criticality restoration (Bhatt et al., 2024), sleep onset as bifurcation (Li et al., 2025), and split-brain holographic degradation (Pinto et al., 2017). Four novel predictions remain untested - including that psychedelics should alleviate anosognosia and that ego dissolution content is controllable via sensory input - predictions no competing theory generates. Changelog v15 # v15 Supersedes v14 (2026-08-06). Two kinds of change: a substantial theory expansion in §4.2, and a systematic accuracy pass over the paper's citations that found — and repaired — a class of defect the previous versions carried. ## The accuracy pass, and why it matters Every citation in the paper was checked against its primary source, asking not "does this work exist" but "does it say what it is cited for". The existence question was already gated: the works exist, the bibliographic details are right, the keys resolve. **Nothing had ever checked characterization.** Sixteen findings resulted, eleven confirmed against primaries, and every one failed in the same direction — toward more support than the source provides. All are repaired here. The three most serious: - A **quotation attributed verbatim to Hohwy & Seth (2020)** did not appear in that paper. The substance of the sentence was defensible; the quotation was not. It now carries their genuine wording. - **Pinto et al. (2017)** was presented as *finding* that each hemisphere retains a functionally complete conscious agent. Their stated conclusion is the opposite — that callosotomy "does not create two independent conscious perceivers within one brain". The theory's reinterpretation of their data stands, but it is now presented as the theory's, explicitly against those authors' conclusion, rather than as their result. - Two quantitative attributions to **Schartner et al. (2017)** — a "15-20%" complexity increase and "dose-response curves" — are absent from that study, which used a single psychoactive dose per drug and reports no such curve. This was the paper's own *quantitative grounding* paragraph for the permeability parameter, and it now states what the study reports and what remains to be done. Also repaired: both species in the criticality row of the FMT-operations table were wrong (the cited works are rat preparations, not turtle and cat), which left the row's own "not mammal-specific" claim unsupported — now sourced to Shew et al. (2015), turtle visual cortex, and Hahn et al. (2010), anesthetized cat; a group-level alignment result described as cross-individual, in three places, including Prediction 5's claim of prior demonstration; a DMT study cited as psilocybin evidence; a correlational imagery result reported as causal, on the paper's anti-epiphenomenalism claim; a single-patient case study carrying a universal "requires"; a citation resolving to no reference entry; statistics attributed to papers that do not contain them; a motor-learning dissociation that contrasts two *implicit* systems cited for the implicit/explicit axis; and focal-seizure evidence deployed inside claims about generalized seizures, now scoped, with the extrapolation stated as the theory's own. Four references were added and three, no longer cited, removed. Every replacement was verified against a primary record before insertion. ## §8.9 — four repairs to the banked results, and a scope clause - An **over-claim**: "the advantage grows by roughly an order of magnitude for each additional subsystem" was false on its own three numbers — the steps are elevenfold and then under threefold. - An **under-claim** in the same paragraph: a scope clause read "one content condition" onto a result measured in four, and implied a number of cost-curve crossings the data does not support. - An **arithmetic inconsistency** that turned out to be two units in one parenthesis: the endpoints are R², while the paired statistic beside them is a reduction in normalized error. Both figures are correct; the sentence now says which is which. - The seventh banked result described its loop arm as a **bottleneck**. Every such arm was in fact simulated as the materialised dense product of its factors. The storage claim is unaffected — the factored bill is the right quantity for what an operator costs to store — but the dynamical description was wrong and now reads as what was actually run. The eighth banked result gains the scope clause it was missing. Its spiking campaign ran throughout without a synaptic filter, which the underlying work named as its most consequential untested assumption. A sweep over three of the four supports has since run. At the substrate's decided synaptic time constant the result reproduces unchanged, rival cost margins included. At the longest constant tested the achievable ceiling falls below the fixed criterion in two of those three supports, where no loop arm reaches it at any budget, so the comparison is not adjudicable there; in the third every loop arm still reaches, at unchanged cost. The boundary between the two lies in an interval the sweep did not resolve. One difference is stated rather than glossed: the paper's near-ceiling bar is *relative*, at 90% of the achievable ceiling, while the criterion held fixed across the sweep is *absolute*. ## §6.0 — source distinguishability, as a requirement and not a mechanism Forking the self-model raises a question the previous derivation did not answer: a forked run and a live one are computed by the same models in the same format, so nothing in the theory made them discernible from within. §6.0 now states the constraint that follows — composing the explicit models must not destroy the source distinguishability the pathways already carry — and states it as a requirement rather than a mechanism. That restraint is the substance of the change, not a hedge around it. A discrete source marker affixed to internally generated states is the position the source-monitoring literature defined itself against in 1993, and the nearest modern candidate has been tested and rejected. The paper therefore claims no such marker. It concedes in its own voice that the empirical literature supplies no mechanism, and states the finding that sharpens the problem rather than solving it: perception carries a bottom-up drive that imagery lacks, and reality judgements do not appear to consult it. The theory's contribution is an ordering — under perturbation, source attribution should degrade before phenomenal experience does — with dreaming the everyday instance and lucid dreaming the recovery case. Five references were added, all verified. ## Vocabulary: "closure", not "return" Where the paper used "return" for what the theory calls closure, it now says closure, and where a sentence needed the mechanism rather than the property it says what feeds back into what. Four occurrences are deliberately unchanged: *return-free*, *returning component*, *non-return* and *return-freedom* are graph-theoretic terms of art, and the sixth banked result is priced on the distinction between them — opening the global loop costs 14.0% and 12.0% and *relocates* closure, while return-freedom, meaning no closed walk anywhere, costs 74.0% and 71.5%. Naming both "closure" would leave the 5.3× and 6.0× multipliers describing nothing. ## §6.3 — a case study is now called one Dresler et al. (2012) was cited as having *shown* increased prefrontal and frontolateral activation in lucid REM sleep. That paper's own title calls it a case study
