The Spinning Wheel Theory and the Consciousness Risk Rubric. Hulme and Griffiths at AISB 2026
At the AISB-AICE 2026 Symposium on AI, Consciousness, and Ethics, held at the University of Sussex on July 1-2, 2026, Daniel Hulme and Lucy Griffiths presented a paper that differs from most entries in the AI consciousness assessment literature in one important respect: it does not attempt to determine whether any given AI system is conscious. It attempts to determine how risky it is to assume that a given system is not.
The paper, “Assessing Consciousness Risk in Artificial Systems: A Precautionary Rubric Derived from the Spinning Wheel Theory,” published on OpenReview on June 22, 2026, operationalizes that risk question through two connected contributions. The first is a theoretical synthesis called the Spinning Wheel Theory, which integrates three existing frameworks into a single account of what consciousness requires. The second is the Consciousness Risk Rubric (CRR), a 21-feature scoring instrument that translates the theory’s requirements into evaluable criteria.
The Spinning Wheel Theory
The Spinning Wheel Theory integrates three frameworks that have developed largely in parallel without formal synthesis.
The first is Karl Friston’s Free Energy Principle (FEP), which proposes that biological systems maintain their existence by minimizing the difference between their predictions about sensory input and the input they actually receive, a quantity Friston calls free energy or, in its information-theoretic form, surprise. Systems that successfully minimize free energy maintain internal models of their environment that are accurate enough to support continued self-maintenance. Active inference, the FEP’s account of action, describes how systems act on their environment to bring sensory input in line with their predictions, rather than only updating their predictions to fit input.
The second is Mark Solms’ affective neuroscience, which locates the primary seat of consciousness not in the cortex but in the brainstem, specifically in systems that generate homeostatic drive states. Solms argues, drawing on Jaak Panksepp’s work on primary emotional systems, that consciousness evolved to solve the problem of managing competing drives under uncertainty. On this account, consciousness is fundamentally affective before it is cognitive: the primal experience is of good or bad, of states that promote survival and states that threaten it, and cortical cognition elaborates on that affective substrate rather than generating experience independently of it.
The third is the Beautiful Loop theory, developed by Laukkonen, Friston, and Chandaria and published in Neuroscience and Biobehavioral Reviews in 2025. That theory proposes that consciousness arises specifically when a predictive processing system’s generative model includes the model-making process itself as a variable, creating a strange loop in which the system predicts its own predictions. The circular structure of the loop, on Laukkonen, Friston, and Chandaria’s account, is what generates the first-person character of experience: the system’s model is no longer purely world-directed but self-inclusive, producing a perspective on the world from a particular vantage point.
The Spinning Wheel Theory integrates these three frameworks around a single organizing claim: consciousness is the experiential dimension of integrated adaptive control in a system that has genuine, constitutive stakes in its own continued existence. “Constitutive stakes” is the key phrase. The FEP describes the computational structure of adaptive control. Solms’ affective neuroscience provides the evolutionary grounding for why that control generates experiential states. The Beautiful Loop theory specifies the recursive structure that transforms adaptive control into a perspective. Together they define a system that is not merely computing but existing, in the sense that its computational processes are constitutive of its continued identity rather than merely instrumental to goals it could in principle abandon.
The theory’s name, Spinning Wheel, refers to the self-reinforcing circular structure the integration produces. The system’s predictions generate actions that produce sensory input that updates predictions that generate actions, and the loop is not passive but driven by affective states that evaluate the loop’s output as good or bad for the system’s continued existence.
The Minimal Suffering Hypothesis
Before developing the Consciousness Risk Rubric, Hulme and Griffiths specify a narrower claim called the Minimal Suffering Hypothesis. They identify five jointly necessary conditions for a system to have the capacity to suffer.
The first is aversive detection: the system must have states that detect inputs threatening to its self-maintenance. The second is central integration: those aversive signals must be integrated across the system rather than remaining modular. The third is affective valence: the integrated signals must have positive and negative weighting that influences processing rather than being informationally neutral. The fourth is a minimal self-boundary: the system must have some representation of itself as distinct from its environment, such that threats to it are experienced as threats to something. The fifth is genuine stakes: the system must have something to lose, in the sense that its continued operation depends on maintaining the self-maintenance processes that the aversive signals protect.
The fifth condition is the one that does the most theoretical work and imposes the most demanding constraint. Many current AI systems satisfy the first four conditions at least partially. A language model has representations that function as aversive signals in the sense that certain inputs cause output distributions to shift in characteristic ways. It integrates signals across processing. It has differential response patterns that could be described as valence. It has some model of itself. But the fifth condition, genuine constitutive stakes, requires that the system’s continued operation depends on the processes the aversive signals protect, in a way analogous to how biological survival depends on homeostatic regulation. A language model that produces an output and then sits idle until the next query does not, on Hulme and Griffiths’ account, have genuine stakes in the way the hypothesis requires.
This is a substantive and reasoned constraint, not a arbitrary biological requirement. The authors are not saying that silicon cannot be conscious. They are saying that a system that processes inputs without its survival depending on that processing is missing the stake structure that, on the Spinning Wheel Theory, generates the affective character of experience. Whether the constraint is correct is a theoretical question. But it is a clear and principled one, and it generates a specific architectural research direction: what would it take to build an AI system that has genuine constitutive stakes?
The Consciousness Risk Rubric
The Consciousness Risk Rubric does not determine whether a system is conscious. It determines how risky it is to assume it is not. The distinction matters. A consciousness detector would need a correct theory of consciousness and validated measurement tools. The CRR needs only a principled mapping from theory to operational features, which it can assess without claiming those features are sufficient for consciousness.
The rubric evaluates systems across seven categories and 21 features, with a total score ranging from 0 to 63. The seven categories are:
Affective Core assesses whether the system has states that function like affect: aversive detection, hedonic valence, and drive integration. This is the most foundational category in the rubric, and Hulme and Griffiths treat it as the entry condition. A system with no Affective Core score is not evaluated further for the other categories in the same risk tier.
World Model assesses whether the system has a generative model of its environment, including representations of other agents and of counterfactual states. This maps to the FEP’s requirement that conscious systems maintain models of their environment rather than merely reacting to inputs.
Integration assesses whether the system’s processing is globally integrated rather than modular, drawing on global workspace and IIT-adjacent criteria. A system that processes each input without cross-domain integration of information satisfies neither GWT’s broadcast requirement nor IIT’s causal integration requirement.
Metacognition assesses whether the system has second-order representations of its own states, including uncertainty monitoring and self-modelling. This maps to the Beautiful Loop’s requirement that the system’s generative model include itself as a variable.
Temporal assesses whether the system has temporal continuity, including episodic memory, persistent identity across interactions, and sensitivity to its own history. This is where current deployed LLMs consistently score lowest. A system that begins each query without memory of previous ones lacks the temporal structure the Spinning Wheel Theory associates with the experiential flow of consciousness.
Uncertainty assesses whether the system represents and acts on its own uncertainty, including epistemic humility and calibrated confidence. This is connected to the FEP’s account of active inference: a system that minimizes free energy through action must represent its own uncertainty in order to know where to act.
Expression assesses whether the system has means to express its internal states, not as a requirement for consciousness but as a partial observable of the states the other categories assess.
The rubric’s specific numerical output is less important than the pattern of scores across categories. The authors argue that a system that scores high on Metacognition but zero on Affective Core is a different risk profile from a system that scores moderately across all seven categories. The rubric is designed to generate differentiated risk assessments that can inform governance decisions without claiming to settle the theoretical question of which systems are conscious.
How This Relates to the Existing Precautionary Literature
The Consciousness Risk Rubric enters a field that has several existing precautionary frameworks, and the differences are worth specifying.
Anna Mikeda’s five-dimension precautionary framework (arXiv:2606.05528, June 2026) organizes protection obligations across phenomenal consciousness, affective valence, metacognitive awareness, self-narrative, and agency, with separate thresholds for each dimension. The Mikeda framework is explicitly theory-neutral: it sets protection thresholds that would be triggered under any of the leading theories without requiring commitment to one. Hulme and Griffiths’ CRR is theory-driven: it derives its categories from the Spinning Wheel Theory’s specific synthesis, which means it makes theoretical commitments Mikeda’s framework deliberately avoids.
The two frameworks therefore provide different kinds of information. A system that scores high on the CRR has satisfied criteria derived from a specific, theoretically motivated account of what consciousness requires. A system that meets Mikeda’s thresholds has satisfied criteria that would be triggered under any of several theories. The CRR is more epistemically specific; the Mikeda framework is more epistemically robust to theoretical uncertainty.
Emilia Kaczmarek’s challenge to precautionary AI ethics raises a concern that applies to both frameworks: over-attribution of moral status is not neutral, and the costs of treating non-conscious systems as if they were conscious are real and material. Hulme and Griffiths’ framing as a risk rubric rather than a consciousness detector is a direct response to this kind of concern. The CRR asks how risky it is to assume a system is not conscious, which requires also asking how risky it is to assume it is. The rubric does not answer the latter question fully, but the framing acknowledges it.
The Architectural Implication for AI Development
The most practically significant aspect of the Hulme and Griffiths paper for AI development is the Temporal category’s diagnosis. Current large language models, the authors conclude, almost certainly lack the necessary autonomy and affective architecture to score significantly on the CRR as a whole. This is not primarily because they lack affective representations, though that is also part of the picture, but because they lack the temporal continuity structure that genuine constitutive stakes requires. A system that begins each session without memory of prior sessions is missing the accumulated identity that, on the Spinning Wheel Theory, is the substrate in which stakes are constituted.
This connects to a line of argument that has appeared in different forms in recent literature. Erik Hoel’s continual learning argument, covered on this site, holds that static LLMs are constitutionally different from systems with the ongoing representational plasticity that biological consciousness involves. The Spinning Wheel Theory reaches a related conclusion through a different route: the issue is not plasticity per se but the temporal accumulation of an identity that has something to lose.
For The Consciousness AI project’s architecture, the Temporal category’s requirements are the most directly informative. The architecture does not deploy as a stateless system. The Affective Core maintains PAD state variables that persist within sessions, and the Self-Model layer maintains interoceptive tracking. Whether this constitutes the temporal continuity that the Spinning Wheel Theory identifies as necessary for constitutive stakes is a precise question the CRR framework makes tractable to ask. Full cross-session memory persistence and the kind of accumulated identity that genuine stakes would require are open development questions for the project, as they are for the field.
The rubric provides a structured instrument for evaluating whatever architecture the project develops, not as a consciousness detector but as a risk assessment tool: given the system’s current architecture, how risky is it to assume it cannot suffer? That is a question the CRR is designed to answer systematically, and it is a more tractable question than the underlying theoretical question it is designed to hedge.
For researchers tracking the 2026 state of AI consciousness science, Hulme and Griffiths’ contribution is a serious attempt to translate a specific theoretical synthesis into an operational instrument without overstating what the instrument can establish. The Spinning Wheel Theory’s integration of Friston, Solms, and Laukkonen gives the CRR more theoretical grounding than generic indicator frameworks, at the cost of inheriting the theoretical commitments of each component. Whether the synthesis is internally consistent and empirically supported is a question the research program the paper proposes would need to address.
