Error often becomes perceptible in the body before it becomes legible in theory. Fatigue, exclusion, imbalance, pain, hesitation, sensory overload and altered capacity can reveal failures that remain invisible inside formal descriptions of a system. ErrorEmbodiment names this conversion of systemic contradiction into bodily evidence. A mistaken assumption does not remain confined to an argument once it has entered a building, interface, workplace, protocol or routine. It becomes a distance that cannot be crossed, a posture that cannot be sustained, a timetable that exhausts, a temperature that excludes, or an instruction that presumes capacities its users do not possess. The body is therefore not merely the recipient of design but an epistemic surface on which institutional assumptions become measurable and contestable. This does not make bodily experience automatically self-explanatory; it makes it indispensable evidence. Correction requires more than acknowledging failure in language. It requires transforming the infrastructures and procedures that repeatedly reproduce the error. Embodied friction becomes a diagnostic instrument for redesigning systems from their consequences outward.
