Theories of consciousness routinely identify a structural measure — integrated information, global broadcast, predictive modeling — with consciousness itself. This essay argues the identification is an artifact of a single fact: we have first-person access to exactly one case, our own, where structure and experience coincide, and we read that local coincidence as an identity holding everywhere. The error is shown to operate even in the field's most careful programs, including the author's own published equation. The correction is a single substitution: the structural measure is a necessary condition for phenomenal experience, not the experience itself — a relabeling that asserts nothing about where experience occurs, only that wherever it does, the structure was required. The consequence runs in two directions. The identity over-attributes mind to systems like logic-gate grids, and it under-recognizes mind wherever a system's structure differs from ours, having quietly made our own topology the measure of all cases. The essay states the diagnosis and the correction; the worked demonstration is named as owed, not delivered. June 25, 2026 — Added hyperlinks from in-text citations to reference entries.
