Most people believe they know what their posture looks like. They don’t.
This isn’t opinion — it’s something I’ve observed clinically for decades and explored formally in a 2024 perspective paper in Frontiers in Neuroscience. Patients consistently overestimate how well-aligned they are. When asked to stand “straight,” most of them aren’t even close. And they have no idea.
In my mind, this gap between their perception and reality is a measure of their Interoceptive Posture Awareness & Accuracy — the degree to which someone can accurately perceive their own body’s position in space. It’s not a disease to be cured or a flaw to be fixed. It’s an expression of neurological function. The brain’s internal model of the body drifts from reality over time, and without external feedback, people have no way to know.
This matters because it changes how we think about addressing posture. Assuming someone could deliver the perfect biomechanical adjustment — address every spinal joint, every tight muscle, every weak link in the chain — if the patient’s sensory input (proprioceptive as well as interoceptive) doesn’t integrate the difference between their old position and the “corrected”one, they drift back. Not because they’re lazy. Because their brain is telling them they’re properly aligned- that’s my normal, that feels right.
The clinical implications are significant. But for the general public, the takeaway is simpler: if you think your posture is fine, you might want to check. Four photographs — an actual pictures of yourself from the front, side, then two more from the front- one balancing on each foot while lifting the other foot. This 4 view series is an Interoceptive Posture Picture, and it will tell you more in 20 seconds than your internal sense of standing tall will tell you in a lifetime.
Interoception is getting more attention in the research world. In 2025, NIH leaders published that interoception may be central to whole person health. The conversation is shifting. And posture — observable, measurable, and trainable — may be one of the most accessible interoceptive interfaces we have.
That gap between what you feel and what’s real? It’s measurable. It’s neurological. And it’s actionable.
