Chapter 1: The Mechanism — How the System Processes

This is the story version. For the formal academic version with full theoretical apparatus, read the technical version.

I remember the first time I caught my own system in the act.

I was in my twenties, mid-conversation with someone I cared about. She said something innocuous — I don’t even remember what — and I felt my chest tighten, my jaw clench, and a wave of irritation rise before I could name it. By the time I opened my mouth, the words that came out were sharp. Not cruel, just… pointed. Precisely calibrated to wound, as if some part of me had already decided this was a threat before the rest of me had finished listening.

Afterward, sitting with the damage, I thought: I didn’t choose that. The irritation was there before I had a thought about it. The sharpness was there before I decided to be sharp. Something inside me had evaluated the input, generated the emotion, and loaded the response — all before “I” got involved.

That was the moment I started looking for the mechanism.

1.1 Emotions vs Emotional State

Here’s something most people never separate, because common language smashes them together: emotions and emotional state are not the same thing.

I learned this from my own body before I learned it from any textbook. On a good day, someone cuts me off in traffic and I wave it off — mildly annoying, forgotten in seconds. On a bad day, the same event becomes proof that the world is hostile. The traffic hasn’t changed. My lens has.

Emotions are physical reactions. Sweating palms, racing heart, gut churning, tension in the chest, tears. They are also sensory re-experiences — your parents’ voices in your head, the flashback of a fight, the visualisation of what might go wrong tomorrow. Emotions are unconscious. They happen to you. You don’t choose to feel the gut-punch of betrayal or the warmth of recognition. They arrive, fully formed, before you have a say.

Emotional state — what people casually call “mood” — is something deeper. It sits between the unconscious emotions and the conscious mind, and it acts as a lens. It determines which emotions get amplified and which get muted. It selects which memories surface. It shapes what you notice and what you ignore.

This is why what we call “personality” is largely a misunderstanding. When your colleague is ruthless in the boardroom but gentle with her kids, she’s not two people. She’s one person in two emotional states. Who you think that person is, is the person’s emotional state while they are in front of you.

I spent years watching people — studying them, practising reading them — before I understood this distinction. Once I saw it, I couldn’t unsee it. The “introverts” and “extroverts,” the “aggressive” and the “passive” — most of it was emotional state masquerading as identity. Including my own.

1.2 The Superego Chain

The moment in my twenties — the one where I said something sharp before I chose to — had a structure to it. It took me years to map it, but the structure was always there.

Freud got the architecture half right. He named three components — Id, Ego, Superego — but he loaded them with baggage that obscures how they actually work. Here’s the remapping:

The Id is not primal drives. It’s storage. The subcortical repository of every Frame you’ve ever absorbed — adopted through conscious growth or hijacked by unresolved trauma — plus every conditioned response, every affective memory. What Freud attributed to destructive human nature is actually accumulated memory. Remove the traumatic conditioning, and what remains is not a seething cauldron but homeostatic biological needs. Self-preserving. Not chaotically destructive.

The Superego is not a moral agent sitting in your cortex. It’s hierarchical evaluative filtering, occurring at every level of the brain. The midbrain Superego filters by biological saliency — is this safe? Dangerous? Relevant? The limbic Superego filters by conditioned experience — has this hurt before? What happened last time? The cortical Superego filters by internalised social rules — how should I appear? What’s acceptable? All of them evaluate input against stored Frames.

The Ego is the conscious processor. It receives what the Superego chain delivers and works with it using 7±2 chunks of working memory. That’s it. Seven items, plus or minus two. Cowan revised this to 3-5 pure items. Meanwhile, subcortical synaptic architecture has 26 discrete size categories, storing approximately 4.7 bits per synapse.

A 7-item processor trying to override a 26-tier system. That’s the fundamental mismatch.

The chain operates like this:

EXTERNAL INPUT (sensory data)
  ↓
MIDBRAIN SUPEREGO evaluates against stored Frames
(biological saliency: safe? dangerous? relevant?)
  ↓
LIMBIC SUPEREGO evaluates against conditioned Frames
(experiential rules: has this hurt before? what happened last time?)
  ↓
Evaluation triggers EMOTIONAL STATE
(the Superego "deems" which emotion matches the Frame)
  ↓
Emotional state triggers STATE-DEPENDENT MEMORY FLOOD
(matching memories pour in — every confirming experience retrieved)
  ↓
CORTICAL SUPEREGO evaluates against social/identity Frames
(internalised rules: how should I appear? what's acceptable?)
  ↓
EGO (PFC) receives the post-filtered, post-flooded result
  ↓
Ego processes with 7±2 chunks
(but the input was curated by a system it didn't control)
  ↓
PLAN → EXECUTE → OUTCOME
  ↓
Outcome stored as new memory → modifies Frames → modifies future evaluation

Now go back to that moment in my twenties. She says something innocuous. My midbrain evaluates it against Frames I didn’t know I had — old Frames from being misunderstood, from years of having my words taken wrong. The limbic system fires: this is the pattern where someone dismisses what you’re saying. The emotional state shifts. Irritation rises. State-dependent memories flood in — every time I’ve been dismissed, condensed into a single feeling of here we go again. By the time the Ego receives the curated package, it’s working with seven items of pre-filtered, emotionally loaded data. The sharpness was not a decision. It was a readout.

The critical insight: the game is decided before the Ego gets involved. The Ego makes “rational decisions” based on a dataset it didn’t curate. This is why people act against their stated values and then rationalise afterward — the Ego is post-hoc narrating a decision that the Superego chain already made.

This is what I was watching all those years — in myself, in every person I studied. Not personalities. Not character. A mechanism, running on Frames most people don’t know they have, producing outputs most people believe they chose.

1.3 The Three Loops

The Superego chain isn’t a one-way street. Three feedback loops run simultaneously, and understanding them explained nearly every emotional pattern I’d ever observed — in others and in myself.

Loop 1: The Somatic Feedback Loop

I used to get panic attacks. Not the dramatic, fall-to-the-floor kind. The quiet kind. Heart racing, shallow breathing, a tightness in the chest that made the world feel like it was closing in. And the worst part: they escalated. The tighter my chest got, the more my Superego interpreted the sensation as danger, which produced more fear, which made my chest tighter.

That’s the somatic feedback loop. When the Superego chain triggers an emotional state, the body reacts — sweaty palms, racing heart, muscle tension. These physical reactions then become new sensory input that re-enters the Superego chain. The body feeds back into the system that triggered it.

The same physical sensation can mean completely different things depending on which Frames interpret it:

Same physiology. Different Frames. Completely different lived experience.

This is why performers who reframe anxiety as excitement actually perform better — the reframe changes which Frames the Superego uses to evaluate the body’s signals, which changes the loop direction. And it’s why meditation and somatic practice work on emotional states. They intervene at the body level rather than the cognitive level. You don’t need to think your way out of a hijacked loop. You can breathe, move, and sense your way out. I learned this the hard way — years of trying to think myself calm before discovering that the body was the actual lever.

Loop 2: The Predictive Loop

The brain is a prediction machine. It constantly generates simulations of the future — what might happen, what could go wrong, what we hope for, what we fear. These predictions are generated from stored Frames and fed back into the Superego chain as if they were external input.

This is anxiety in its purest form: the prediction engine running hijacked Frames produces threat predictions, which the Superego evaluates as dangerous, which produces more fear, which biases the prediction engine toward more threats. A self-reinforcing loop running entirely on internal input. Nothing is actually happening. But the system can’t tell the difference between a predicted threat and a real one.

I watched this loop run in myself for years before I understood it. Lying awake at 3 AM, my brain generating catastrophic futures — business failing, relationships collapsing, being exposed as a fraud — and my body responding to each prediction as if it were already happening. Heart racing. Cortisol surging. All in response to a simulation.

But here’s the thing the anxiety literature rarely mentions: the same loop produces Vision. The difference between anxiety and vision is the Frame direction:

Dreams are the prediction engine running during sleep. Intuition — the “gut feeling” — is predictions generated from Frames so deep that they don’t surface with a verbal explanation. Learning to trust those deep predictions rather than dismissing them as irrational was one of the most important transitions I ever made.

Loop 3: The Complete Mechanism

All three loops running simultaneously:

┌─────────────────────────────────────────────────────┐

           │        Outcome stored → modifies Frames
           │
           ▼
    BODY REACTS (somatic response)
           │
           ▼
    Body reaction becomes NEW INPUT
    to Superego chain (somatic feedback loop)

Three loops, one system. The Superego chain evaluates input against Frames. The somatic loop feeds the body’s reaction back into the chain. The predictive loop generates futures from Frames and feeds them back as input. All running at once, all below conscious awareness, all delivering a curated package to the 7-item processor that thinks it’s in charge.

1.4 The Friston-Bach Synthesis

For years, I had the phenomenology — what the mechanism feels like from inside. What I didn’t have was the formalism. Why does this system work this way? What is it actually computing?

Two thinkers provided the answer, from complementary angles. And the moment I understood the connection between them, the entire architecture had a mathematical foundation.

Friston: The Mathematics

Here’s something your brain is doing right now, as you read these words. Before your eyes reach the end of this sentence, your visual cortex has already predicted what the next word will be. If I write something expected, the prediction is confirmed and the system barely registers it — low prediction error, low energy cost, move on. But if I write GIRAFFE, something different happens. The system jolts. A spike of surprise. Your attention sharpens. Your brain has to update its model because what arrived didn’t match what was predicted.

That jolt — the difference between what you predicted and what actually happened — is what Karl Friston calls prediction error. And his Free Energy Principle proposes that minimising it is what all self-organising systems do. Not just brains. All living systems. From single cells to human civilisations.

The core equation: F = Complexity - Accuracy. The system seeks the simplest model that accurately predicts the data.

Two ways to minimise free energy:

1. Perceptual inference (passive): Change the internal model to better fit sensory data. Update your beliefs.
2. Active inference: Change the world to better fit the internal model. Make your predictions come true.

That second one stopped me cold when I first read it. Because active inference is exactly what the saviour mode was doing. I wasn’t updating my model of relationships based on evidence. I was changing the relationships to fit my model — constructing environments of people who needed carrying, so that my prediction (“I must carry to belong”) was always confirmed. The model was wrong. But the strategy was keeping the model’s prediction error low by reshaping reality to match the distortion. Brilliant, in a terrible way.

Precision weighting is the mechanism of attention. The brain doesn’t just process data — it estimates which data is reliable. High precision on a prediction error forces the model to update. Low precision causes the brain to ignore sensory data and rely on priors. Attention IS the inference of precision.

When I first encountered this, the Superego Chain suddenly had a mathematical foundation:

And then the critical insight — a hijacked Frame, in Fristonian terms, is a prior with inappropriately high precision. The system treats it as more reliable than incoming evidence, overriding what you actually see and hear. You “know” your partner isn’t betraying you (evidence), but you “feel” betrayed (high-precision prior from trauma). The prior wins. Healing is reducing the precision of the traumatic prior until evidence can compete.

This is what therapy does, stripped to its mechanism. It creates a safe environment where the system can experimentally reduce prior precision without catastrophic consequences. The therapist is a prediction-error generator in a safe container. Each session where the client expects rejection and receives acceptance is a small reduction in the traumatic prior’s precision. Enough sessions, enough disconfirmations, and the prior loosens its grip. Not because the client “decided” to think differently — because the system updated its model through accumulated evidence.

Mood as hyper-prior: Mood is not an emotion. It’s a higher-order prior over precision itself — a meta-setting that determines how much weight the system gives to its own capacity to influence outcomes. Low mood is a chronic estimation that your actions cannot change results. This is why the “lens” metaphor works: mood doesn’t change what you see. It changes how much you believe what you see matters. Depression, in this framework, is a precision configuration — overly precise negative priors with reduced precision on the active inference pathway. The system has concluded that acting on the world doesn’t work, so it stops trying.

Bach: The Computational Architecture

Joscha Bach’s MicroPsi framework provided the other half — not what the system computes, but how it’s architecturally configured.

Think of it this way. Your phone has the same hardware whether you’re running a game, a spreadsheet, or a meditation app. What changes is the software configuration — which processes get priority, how much memory each one gets, how fast the screen refreshes. Bach argues that the brain works similarly. The hardware is constant. The modulators — global variables that change how the hardware processes — are what produce different “personalities.”

Three modulators matter most:

• Arousal: Speed of processing vs accuracy. High arousal = snap judgements, binary thinking. Low arousal = detailed processing, nuanced evaluation.
• Resolution Level: Detail of mental representation. High resolution = you see the 47 shades of grey in the situation. Low resolution = you see black and white.
• Selection Threshold: How much competition a thought needs to win attention. Low threshold = everything competes equally (this is what ADHD often feels like — every signal demanding attention simultaneously). High threshold = only the strongest signals get through.

This is the computational proof of the Fundamental Claim: personality IS emotional state in configuration. Change the arousal, resolution, and selection threshold settings, and you get a different “personality.” The Big Five personality traits measure the current modulator configuration’s behavioural output — stable because the modulators haven’t been adjusted, not because they can’t be.

I know this from the inside. On a day when my arousal is high and my resolution is low — stressed, tired, triggered — I am a different person than on a day when the arousal is regulated and the resolution is high. Not a little different. Measurably, observably different. Different patience threshold. Different quality of listening. Different capacity for nuance. The “personality” people see is whichever modulator configuration they happened to encounter.

Consciousness is a protocol of attention — a learning algorithm that maximises global coherence by filtering contradictions. It only activates when models need updating due to uncertainty. Once tasks are optimised, the brain stops attending. This explains a phenomenon I’d observed for years without being able to name it: people stuck at Stage 3 (Muted) are largely unconscious of their own operation. The system appears to be working, so the attention protocol has disengaged. They’re running legacy code with no read access.

Agency vs the model of agency. Bach distinguishes actual agency (a cybernetic controller using counterfactual reasoning) from the experience of agency (a model of the control loop — a UI feature, not a metaphysical reality). The person using willpower is deploying the model of agency to fight the actual agency. A low-resolution representation trying to override the high-resolution system it represents. It loses because it’s operating on a simplified version of what it’s trying to control.

Suffering as regulation failure. Suffering occurs when the mind identifies a problem it cannot solve. The trainer — the subsystem generating the signal — cranks up intensity because the trainee — the self-model — isn’t fixing the issue. But the issue may be unfixable at the level being addressed. Resolution requires: solving the problem, recognising it’s unregulatable and releasing the attempt, or changing the level of identification so the signal is no longer addressed to “you.”

That last option — changing the level of identification — is what contemplative traditions have been teaching for millennia. It’s also what I experienced during the unmasking: the recognition that the masks weren’t “me” but programs running on my hardware. Once you see the program as a program, the suffering it generates is no longer addressed to “you.” It’s addressed to a version of you that you can now observe rather than be.

The Synthesis

Together, Friston and Bach describe the same system from complementary angles:

1.5 Why Willpower Fails — And What Replaces It

I was the Unbreakable One. That was one of my masks. Handle anything — medical school, career pivots, business failures, relationship breakdowns — and keep functioning, keep producing, keep showing up. The mask wasn’t resilience. It was the inability to give myself permission to stop.

I ran on willpower for decades. And it worked — until it didn’t. The collapses, when they came, were sudden from the outside but years in the making. Each one was the delayed bill for months of running past empty.

Here’s what the science says about why:

Executive function is a prioritisation system, not a battery. The original “ego depletion” model proposed willpower as finite fuel. Large-scale replication studies failed to confirm this. The better mechanism is metabolic cost: intense cognitive effort causes glutamate to accumulate in the lateral prefrontal cortex, making further PFC activation neurochemically expensive. The brain doesn’t run out of gas — it calculates that continued override exceeds the perceived benefit and shifts toward low-effort, high-reward alternatives.

This is compounded by the paradox of suppression: expressive suppression — the primary strategy of anyone running on willpower — occurs after the emotion has already triggered subcortical systems. Neuroimaging shows that while the PFC works to suppress expression, amygdala and insula activity actually increases. The harder the rider pulls the reins, the more agitated the elephant becomes.

When the cost-benefit calculation tips — through sustained suppression, stress accumulation, sleep deprivation, or simply too many decisions — the elephant goes where its conditioning directs. The “sudden” personality shift, the breakdown, the explosion — these are not failures of character. They are the rider dismounting from a strategy that was never efficient.

I know this because I lived it. Every burnout cycle I went through followed the same pattern: sustained override → accumulating cost nobody could see → sudden collapse → confusion from everyone around me (“but you were doing so well”) → rebuild the mask → repeat. The mask of the Unbreakable One was the most expensive one I wore, because it convinced everyone — including me — that the strategy was working.

What replaces willpower: You stop trying to out-muscle the elephant and start learning what the elephant actually wants and why. In neuroscience terms, this is reappraisal vs suppression — and reappraisal is neurologically cheaper and actually down-regulates the amygdala, while suppression increases it.

In Bach’s terms: the upgrade is gaining access to the mechanism itself. Not doing the same thing harder, but operating at a different level. In Friston’s terms: reappraisal changes the generative model, which changes the predictions, which changes the prediction errors, which changes the emotional state. Suppression tries to override the emotional state without changing the model. The model keeps generating the same predictions. The suppression must continue indefinitely — or fail.

One more thing the willpower narrative hides: the capacity for willpower is not equally distributed. Higher socioeconomic status correlates with greater PFC volume. The privileged class has more PFC bandwidth, which means their willpower works more often — not because they are more disciplined but because their neural hardware was developed in conditions that supported PFC growth. “Just try harder” is not advice. It is a hijacked Frame protecting the privileged identity from the structural truth of how success actually works.

1.6 The Assumptions That Load-Bear This Chapter

1. Everyone inherently wants to be their version of good. The biological Id is homeostatic — oriented toward the organism’s version of good. For a subset with reduced empathy hardware, homeostasis is survival-egoistic, not chaotically destructive.
2. There is always a biological layer. Temperament, baseline reactivity, genetic predispositions. Biology is the floor, not the ceiling.
3. Emotional states are subconscious and can be understood and managed. This is learnable, not innate — against a biological baseline that varies.
4. What we call “personality” is largely emotional state in context. Observable surface of thought processes filtered through emotional maturity.
5. Trauma hijacks at the Frame stage, converting values-driven frames into anti-values-driven frames. Trauma operates ON a biological substrate — the same trauma affects different nervous systems differently.

1.7 Tensions and Limits

FEP unfalsifiability. Friston explicitly states: “The free energy principle is what it is — a principle. It cannot be falsified.” He compares it to the Principle of Least Action in physics. Only the process theories derived from it (predictive coding, active inference) are testable. This chapter uses Friston as a compatible mathematical framework, not as proof.

Bach’s MicroPsi is untested against human data. The framework has been demonstrated in limited AI agent environments but not validated against human cognitive data at scale. The claims about consciousness and suffering are philosophical positions with computational framing, not empirical findings. They are compatible with the architecture and illuminating as a lens — but they are not proof.

Solms/Panksepp subcortical consciousness is a minority position. Critics distinguish wakefulness (brainstem) from awareness (cortex). The model uses Solms/Panksepp’s nested hierarchy as a useful mapping, not as settled neuroscience.

Polyvagal Theory has phylogenetic problems. Grossman’s critique undermines the specific phylogenetic ladder. The ESM-to-autonomic mapping is useful clinically but the theoretical basis is contested.

The sequential Superego Chain is a pedagogical simplification. The brain processes in parallel, not sequentially. The chain captures the functional hierarchy without claiming strict sequential processing.

Chapter 1 establishes the mechanism. The system processes input through hierarchical evaluation, amplified or dampened by three feedback loops, running on a precision-weighted architecture with configurable modulators. The game is decided before the Ego gets involved. Willpower is the wrong tool — it fights the mechanism instead of accessing it.

But the mechanism alone does not determine outcome. The same mechanism produces completely different results depending on which way the Frames point. That is Chapter 2.
