The Affect Signature of Inhibition

ι\iota is not another dimension of affect. It is a meta-parameter governing the coupling structure between all the structural dimensions—a dial that changes how the axes relate to each other and to perception.

SM\mathcal{SM}Variable, often lowVariable, often highParticipatory mode dissolves self/world boundary; mechanistic sharpens it

The central affect-geometric cost of high ι\iota is reduced integration. Participatory perception couples perception, affect, agency-modeling, and narrative into a single integrated process. Mechanistic perception factorizes them into separate modules—perception here, emotion there, causal reasoning somewhere else. The factorization is useful because modular systems are easier to debug, verify, and communicate about. But factorization reduces Φ\intinfo, and reduced Φ\intinfo is reduced experiential richness. The world goes dead because you have learned to experience it in parts rather than as a whole.

The mechanism behind the effective rank shift deserves explicit statement. When you perceive something at low ι\iota—participatorily, as alive and interior—your representation of it must encode dimensions for its goals, its beliefs, its emotional states, its narrative arc, its possible intentions, its relationship to you. Each attribution of interiority adds representational dimensions along which the perceived object can vary. A tree perceived participatorily varies in mood, in receptivity, in seasonal intention, in its relationship to the grove. A tree perceived mechanistically varies in height, diameter, species, leaf color. The first representation has higher effective rank because more dimensions carry meaningful variance. This is not projection in the dismissive sense—it is the natural consequence of modeling something as a subject rather than an object. Subjects have more degrees of freedom than objects because interiority is high-dimensional. The reff\effrank collapse at high ι\iota is not a loss of information about the world; it is a loss of the dimensions along which the world was being modeled. The world becomes simpler because you have decided—or been trained—to perceive it as having fewer degrees of freedom than it might.

Follow this consequence to its end. If the identity thesis is right—if experience is integrated cause-effect structure—then ι\iota does not merely change the quality of perception. It changes the quantity of experience. This inference requires a specific step that should be made explicit: IIT identifies Φ\intinfo as the quantity of consciousness, not merely its quality. A system with Φ=10\intinfo = 10 is more conscious (has more phenomenal content, more irreducible distinctions, more of what-it-is-like-ness) than a system with Φ=5\intinfo = 5, in the same sense that a system with more mass has more gravitational pull. This is a controversial claim within IIT (and one of its most debated features), but given the identity thesis, it follows: if experience IS integrated cause-effect structure, then more integration is literally more experience. One might object that factorized perception could be differently structured rather than less structured—that compartmentalized modules might each carry their own experience. IIT’s response is that the experience of the whole system is determined by the integration of the whole, not the sum of its parts’ integrations. Factorization reduces the whole-system Φ\intinfo even if individual modules retain local integration. The mechanistic perceiver may have rich modular processing, but the unified experience—the single subject—has less phenomenal content.

Given this, a system at high ι\iota has genuinely lower Φ\intinfo, genuinely fewer irreducible distinctions, genuinely less phenomenal structure. The mechanistic perceiver does not see the same world with less coloring; they have a structurally impoverished experience in the precise sense that IIT defines. The “dead world” of mechanism is not an illusion painted over a rich inner life. It is a real reduction in what it is like to be that system. The cost of high ι\iota is not just meaning—it is consciousness itself, measured in the only units that consciousness comes in.

This cuts both ways. If low ι\iota increases Φ\intinfo, then participatory perception is not merely a “warmer” way of seeing—it is a richer experience in the structural sense, with more integrated distinctions, more phenomenal content, more of what the identity thesis says experience is. The animist is not confused. The animist is more conscious, in the IIT sense, of the thing being perceived. Whether the additional phenomenal content is accurate—whether the rock really has interiority—is a separate question from whether the perceiver has more experience while perceiving it.

Open Question

Is ι\iota really a single parameter? The five features of participatory perception might be somewhat independent—you could have high agency detection with low affect-perception coupling. The claim that one parameter governs all five is empirically testable: if ι\iota is scalar, then the five features should correlate strongly across individuals and contexts. If they don’t, ι\iota may need to be a vector. The framework accommodates either case, but the scalar version is more parsimonious and should be tested first.

The trajectory-selection framework (Part I) reveals a further consequence. If ι\iota governs the breadth of the measurement distribution—how much of possibility space the system samples through attention—then ι\iota governs the range of accessible trajectories. A low-ι\iota system attends broadly: to agency, narrative, interiority, counterfactual futures, relational possibilities. Its effective measurement distribution is wide. It samples a large region of state space and consequently has access to a large set of diverging trajectories. A high-ι\iota system attends narrowly: to mechanism, position, force, present state. Its measurement distribution is peaked. It samples a small region and follows a more constrained trajectory. The phenomenological consequence is that high ι\iota feels deterministic. The mechanistic worldview is not merely an intellectual position about whether the universe is governed by law. It is a perceptual configuration that literally narrows the set of trajectories the system can select from. The world feels like a machine because the observer has contracted its measurement apparatus to sample only machine-like features. Low-ι\iota systems experience more accessible futures, more agency, more openness—not because they have violated physical law, but because their broader attention pattern selects from a wider set of physically-available trajectories.

Proposed Experiment

Operationalizing ι\iota. The inhibition coefficient must be independently measurable, not merely inferred post hoc. Candidate operationalizations:

  1. Agency attribution rate: Forced-choice paradigm presenting ambiguous stimuli (Heider-Simmel animations with varying parameters). Rate and speed of agency attribution as a function of stimulus ambiguity gives a behavioral ι\iota proxy: low-ι\iota perceivers attribute agency earlier and to less structured stimuli.
  2. Affect-perception coupling: Mutual information between perceptual features (color, texture, movement) and concurrent affective state (valence, arousal via physiological measures). Low ι\iota implies tight coupling; high ι\iota implies decoupled streams.
  3. Teleological reasoning bias: Kelemen’s promiscuity-of-teleology paradigm applied across age, culture, and expertise. Rate of accepting teleological explanations for natural phenomena indexes low-ι\iota reasoning.
  4. Neural correlate: If the predictive-processing account is correct, ι\iota should correlate with the precision weighting of top-down priors in perception—measurable via mismatch negativity amplitude or hierarchical predictive coding parameters.

If ι\iota is a genuine scalar parameter, these four measures should load on a single factor. If they fractionate, ι\iota is better modeled as a vector (see open question above). Either result is informative; only the absence of any systematic structure would falsify the concept.

and the Gradient of Distinction

The inhibition coefficient connects to the gradient of distinction introduced in Part I. The gradient produces existence from nothing, life from chemistry, mind from neurology. The same distinguishing operation, applied with maximum intensity to the self-world boundary, produces the mechanistic worldview: the self so sharply bounded from the world that the world loses the interiority the self kept for itself.

Low ι\iota means the self remains porous to the gradient—still participating in the universal process of distinguishing, still experiencing the world as alive with the same process that constitutes the self. High ι\iota means the self has sharpened its own boundary so aggressively that it can no longer perceive the gradient in other things. The deadness of the mechanistic world is not a property of the world but a property of the maximally-distinguished self’s perceptual mode.

There is a deeper reading. Part I established that attention selects trajectories: in chaotic dynamics, what a system attends to determines which branch of diverging possibilities it follows. If ι\iota governs attention breadth—low ι\iota spreading processing across interiority, agency, teleology, narrative; high ι\iota contracting it to mechanism, mass, trajectory—then ι\iota governs the breadth of the measurement distribution through which the system samples reality. Low-ι\iota observers are sampling a wider region of possibility space (including dimensions where entities have purposes, relationships have meaning, events have narrative arcs). High-ι\iota observers are sampling a narrower region (only dimensions where objects have positions and forces). Each observer’s experienced trajectory—the sequence of states they become correlated with—follows from what they attend to. The animist and the mechanist may inhabit the same physical environment but follow genuinely different trajectories through it, because their attention patterns select for different features of the same underlying dynamics.
