A working pseudoscientific model. Not scientifically validated. Actively being developed. Shared because it's been useful to me.
For most of my adolescence, I had a religious framework that organized my understanding of myself and the world. When I left it, I eventually built a replacement — not deliberately at first, but as a kind of side effect of trying to make sense of my own behavior.
The original version was embarrassingly overconfident. I called it a "scientific theory" for longer than I should have. After taking formal psychology classes and reading Kahneman's Thinking, Fast and Slow, I recognized several fundamental problems with how I was building it — primarily that nothing in it was falsifiable enough to qualify as a theory in any scientific sense. I've since tried to be more careful about what I'm claiming.
What CUT is: a personal working model of human motivation. Built from neuroscience, cognitive psychology, and older models like Maslow's hierarchy of needs and Graves' model of human existence. Iteratively refined through observation, reading, and personal experience. Useful, I think — at least for me. But not validated, not rigorous, and actively being revised.
Every human behavior, feeling, or desire ultimately traces back to a set of intrinsic drives — inborn motivational forces, each associated with a specific chemical messenger in the brain and body.
You're not really pursuing "happiness" or "success" as abstract ideals. You're pursuing the neurochemical states those things produce. The specifics matter: someone who feels fulfilled when they complete a difficult task is different from someone who feels fulfilled when they feel deeply understood by another person — and that difference maps, in CUT's model, onto a difference in their underlying drive hierarchy.
This reframe has been practically useful to me because it makes the question "what do I want?" more tractable. Instead of trying to define "a fulfilling life" at the level of abstraction where everyone's answer is vague and different, you can go a level down and ask: what does my body actually need right now?
An intrinsic drive is an inborn motivation tied to a specific chemical messenger. Each drive has a baseline importance — what I call its intrinsic intensity — that's roughly stable across a person's lifetime. Extreme trauma can shift it; strong conditioning can shift it. But it's not arbitrarily malleable, and it doesn't reset every time your circumstances change.
My current working model identifies six primary drives — the ones that vary meaningfully enough between people to form the basis of personality differences:
| Drive | Chemical | Core Need |
|---|---|---|
| C | Cortisol | Eliminate threat, establish stability |
| D | Dopamine | Goal pursuit, achievement, acquisition |
| E | Endorphins | Sensory stimulation |
| O | Oxytocin | Trust, bonding, secure social connection |
| S | Serotonin | Contentment, self-esteem, internal order |
| V | Vasopressin | Protection, fidelity, territorial security |
These aren't the only drives — far from it. The full list includes basic survival drives like ghrelin (hunger), adenosine (sleep need), Substance P (pain signaling), and others. The reason I focus on C, D, E, O, S, and V is that those are the ones that vary enough between individuals to form the basis of meaningful personality differences. Almost everyone has roughly the same relationship with hunger. Not almost everyone has roughly the same relationship with the need for achievement versus the need for connection.
High-intensity drives — the drives for basic survival, pain avoidance, sleep — have extremely low variance between people. Everyone cares about them roughly equally, because selective pressure is strong: people who didn't care enough about avoiding pain didn't survive long enough to pass that trait along.
Lower-intensity drives vary enormously. The evolutionary pressure is weaker; individual environments, genetics, and experience all leave a larger fingerprint. One person's dopamine drive might be significantly more intense than another's, making achievement a much more central organizing force in their life.
CUT's hypothesis is that the variance in a drive's intensity is inversely proportional to its average intensity. High-intensity drives = low variance between people. Low-intensity drives = high variance. That's where personality lives.
When a drive goes unmet for long enough, its current manifested intensity — how loudly it's demanding your attention right now — spikes above its baseline. If it spikes enough, you enter a feedback loop: the unmet drive generates thoughts that amplify the feeling, which generates more thoughts about the same thing, which amplifies the feeling further.
Most people have experienced this directly. Hunger is the obvious example: think about food while hungry and you get hungrier. Social anxiety spiraling is another: noticing your anxiety makes it worse. The loop structure is the same.
The practical implication is that breaking loops is the unit of personal development in this model. You're not trying to achieve some abstract "self-actualization." You're trying to identify the loudest active loop and satisfy the underlying drive.
This also explains why Maslow's hierarchy roughly works as a developmental model: we break the loudest loops first (survival, safety), then gain the mental bandwidth to hear the quieter ones. The order is predictable at the high end and highly individual at the low end.
What many frameworks describe as "developmental stages" are, in CUT's model, just the observation of someone sequentially breaking their loudest feedback loops. The apparent progression isn't a fixed staircase — it's a consequence of the intensity hierarchy. You don't move from "safety needs" to "social needs" because you've completed a stage; you move because the cortisol loop has gone quiet enough that the oxytocin loop can finally be heard.
When all drives are consistently satisfied and no feedback loops form naturally, I describe the resulting state as Unnoeia — loosely, "the unburdening of thought."
I'll be direct about the epistemic status of this: it's the most speculative part of the model. I can't point to rigorous research that studies this specific state, and I haven't reliably reached it myself. The phenomenological description — a settled state where you're no longer being hijacked by urgent needs, and can think more systemically as a result — resonates with what Graves described as "Second-Tier Consciousness" and what various contemplative traditions call equanimity.
I think of it less as a destination and more as a direction. Moving toward it means progressively identifying and satisfying the drives that are looping most loudly. That's a useful project regardless of whether you accept the full model.
CUT is not:
What it might be: a useful lens. A framework for asking better questions about yourself. A vocabulary for things you already know intuitively but haven't quite had language for.
That's how I use it.
