There is an argument going on right now and it is worth understanding even if you have never read a trauma book.

Recently a paper came out in a neuroscience journal with a deliberately provocative title: "The body does not keep the score." One of its authors is Karl Friston, one of the most influential neuroscientists alive, and the researcher most associated with the idea that the brain runs on prediction. The paper is a direct response to the most famous idea in modern trauma culture, the one from the bestselling book "The Body Keeps the Score": that your body stores your trauma.

The somatic and bodywork world is upset. People feel like the foundation got kicked out from under them.

I want to walk through what the paper actually says, because both sides are circling the same truth and missing it, and because the answer turns out to be the same answer that explains your posture.

What the paper actually argues:

Trauma is not stored in your tissues. Your fascia is not a hard drive. There is no compressed memory of a bad day living inside your hip that a deep enough massage will release. Tissue with no nerve supply cannot "hold" an experience, because holding an experience requires a nervous system.

That part is correct. And if you read the original book carefully, the author never actually claimed trauma lives in your fascia. That idea is a folk version that grew up around the title.

It also matters who is making this critique. This is not an attack from someone who rejects the nervous-system view of trauma. It comes from the camp that built the modern science of how the brain predicts. The critique is from the inside.

So if it is not in the tissue, where is it?

The paper's answer: it is in the nervous system, as a prediction that got stuck. A healthy brain is constantly forecasting what is about to happen and updating that forecast against reality. After trauma, the system loses flexibility. It locks onto one forecast: danger. It stops updating. It keeps running the old model no matter what the present actually contains.

Here is the part both sides miss.

That stuck forecast does not stay in your head. It cannot. Your brain's number one job is to run your body. A forecast of danger is not an abstract thought. It is a set of physical instructions sent down to your muscles, your breath, your gut, and your jaw, every second of every day.

So trauma is not stored in the body. It is played by the body. Continuously. Right now. The bracing, the held breath, the collapsed chest, the guarding, the inability to fully rest. None of that is a recording of an old event. It is a live broadcast of a present-tense prediction. The body is the instrument the old forecast keeps playing through.

That is exactly why body-based work works, and why the new paper does not actually threaten it. You are not digging out a buried object. You are interrupting a live signal and giving the system enough new evidence to update the forecast.

Now here is why I am posting this in a posture sub.

Everything I just described is also the correct description of your posture.

Your posture is not stored in your spine. It is not a fixed structure you are stuck with. It is a prediction. Every millisecond, your nervous system generates a best guess about how to hold you up, based on what it currently believes about how safe and stable you are. The slump, the forward head, the chronic brace between your shoulder blades. Those are not character flaws or weak muscles. They are a forecast made physical.

Posture and trauma run on the same wire. Literally the same circuitry. A nervous system that predicts threat does three things you can read from across a room: it braces the back of the body, it pulls the head forward, it shortens the breath. A nervous system that predicts safety lets the spine lengthen and the face open. Posture is autonomic state made visible. A trauma researcher and a posture nerd are reading the same instrument from opposite ends.

This is also why "just sit up straight" fails the same way "just calm down" fails. You are giving a conscious instruction to a system that is not running on conscious instructions. It is running on a prediction. You cannot argue a forecast into changing. You can only feed it new evidence.

So the takeaway from all the drama, for anyone working on a body:

The body is not the hard drive. Stop trying to delete a file that was never there. The body is the keyboard. It is the surface where the nervous system's prediction gets expressed, which means it is also the surface where you get to enter something new. Change what the system consistently feels, and the prediction updates. The posture follows. The guarding follows. Not because you forced it. Because the forecast changed.

The paper is not the end of body-based work. Read properly, it is the strongest case for it anyone has made in years.

I visited SOSORT 2026, the world's leading international congress for non-surgical scoliosis treatment. 147 research resaerch abstracts presented over three days. These are the people who set the conservative-care standard your clinician eventually inherits.

I want to give you an honest debrief. The good and the disheartening. Because if you have a curve, what happens in that room is what eventually happens in your appointment.

The good first.

A handful of research teams are independently converging on something I have been arguing for years: that scoliosis is a nervous-system problem before it is a bone problem. Not teams who read each other. Teams on three different continents, who submitted their work months before they could have seen mine, arriving at the same place through different doors.

A group in China ran a trial comparing standard scoliosis exercise against an intervention built around "remodeling neural control" instead of correcting the bone directly. The brain-based group nearly doubled the curve reduction of the standard group (5.8 vs 3.1 degrees of Cobb change).

A group in Hong Kong took apart a scoliosis-exercise trial to find out why it worked. The muscle improvements explained only about a third of the result. The rest of the effect ran through something they did not measure. Their own best guess for the missing piece: proprioception. The body's sense of itself in space.

A group in Milan, the largest conservative-scoliosis institute in the world, reviewed 89 brain and nervous-system studies in scoliosis and concluded the field is looking at "altered sensorimotor integration," not isolated structural defects.

That is real movement. I met some of these people, started some conversations, and I am genuinely hopeful about where they go.

Now the disheartening part.

I did something simple. I took all 147 abstracts and counted the words. What a field measures is what a field believes. So I looked at what they measured.

Out of 147 abstracts, here is how many mentioned each idea:

Cobb angle (the bone measurement on an X-ray): 105
Curve / curvature: 86
Bracing: 76
X-ray / imaging: 69
Surgery / fusion: 59
Exercise: 50

And here is the upstream vocabulary. The nervous-system words:

Proprioception: 7
Sensorimotor: 5
Brain / cortex: 4
Vestibular (your balance system): 4
Nervous system: 3
Somatosensory: 2

and the kicker:

Interoception (your felt sense of the body from the inside): 0

Zero. Out of 147.

The field is studying the printout. The Cobb angle is a number on an X-ray. It measures the curve. It does not measure what is writing the curve. Almost the entire research attention of the world's leading conservative-scoliosis body is pointed at the printout.

Here is why, and it is not a conspiracy. Look at the full name. SOSORT stands for the Society on Scoliosis Orthopaedic and Rehabilitation Treatment. Orthopaedic is built right into the name. It is, by definition, an orthopedic organization, and orthopedics is the study of bone and structure. The room is full of careful, intelligent people doing careful bone work. But scoliosis did not read the org chart. The hypothesis I work from did not come from inside orthopedics. It came from reading across neuroscience, genetics, developmental biology, and motor control. The fields that would explain a curve are not the field that owns the curve.

If a team genuinely wanted to test whether scoliosis starts upstream, the studies are not exotic. Image the brains of kids who carry the genetic risk before any curve appears, and watch which change comes first. Measure proprioception and balance alongside the X-ray, not instead of it. Track the sensory system over time, instead of photographing the bone once a year. The patient populations exist. The scanners exist. What is missing is the question.

So here is the honest timeline. Conferences move slow. The full papers behind those abstracts publish 6 to 12 months from now. Then they get cited, debated, replicated. Then, maybe, they reach a textbook. Then they reach the clinician who trained on the old textbook. Realistically you are looking at 3 to 5 years before your local doctor even catches a glimpse of this. If you are a teenager with a curve right now, that is most of the window you have.

Which is the real reason I am writing this.

You have to become your own advocate. At every age, but especially young.

I know how hard that is, because I got it wrong. I walked out of an orthopedic surgeon's office at 18 with a diagnosis and nothing else. And I genuinely thought: that man knows everything there is to know about this. Why would I go looking. How would I even know where to look. I am not a medical person.

That assumption cost me years. The truth I eventually hit was simpler and stranger than I expected: nobody has this fully figured out. Not the surgeon. Not me. The only thing that separates people is whether they keep looking.

So here is the hypothesis I work from, stated plainly.

Your nervous system does not read your posture off your bones. It builds your posture as a prediction. It takes a constant stream of sensory information about where your body is in space, from your inner ear, your eyes, your joints, the pressure under your feet, and from that it generates a best guess of what "upright" is. Your spine organizes to match the guess.

In scoliosis, that sensory stream is degraded and lopsided. The signal on one side does not match the signal on the other. So the internal guess of "upright" is itself crooked, and the spine faithfully bends to meet it. The spine is not failing. It is following a map that has drifted. The bone is the last domino, not the first.

If that is true, three things follow, and all three matter for you.

First, the work is upstream. You change the curve by changing the quality of the sensory information the system runs on, not by forcing the bone. This is why bracing and general strengthening produce such variable results. They act on the last domino.

Second, there is far more room to move than the bone-deformity story allows. A nervous system can be retrained at any age. A drifted map can be redrawn. The fatalism most of us were handed, that a curve only holds steady or gets worse, is a property of the old model, not of your body.

Third, the thing you are actually working with is sensation, not willpower. Not "try harder to stand straight." Your body does not take instructions. It takes evidence. The work is restoring an accurate felt sense of your own body, so the prediction has honest information to run on. It is quiet and internal. It does not look like exercise, and that is exactly right.

So that is my mission, and why I will keep posting things like this. To make this understandable enough that you stop waiting for the answer to be handed to you from the outside. That is where I spend all of my time now, working with people upstream, and I am seeing changes the old model says should not happen.

The field will get here. It is going to take time. You do not have to wait for it.

Happy to answer questions in the comments.

A major new paper argues "the body does not keep the score." Why that is not bad news for body-based work, and what it reveals about why you cannot just sit up straight.

I went to the world's biggest scoliosis research conference this year (SOSORT 2026). An honest debrief: the good news, and the part that worried me.
