Physicists agree on the predictions of quantum mechanics — confirmed, wherever tested, with extraordinary precision. What they have never agreed on is what the theory says the world is like. This instrument asks you eight questions — one commitment each — and then tells you where your answers land: squarely on a named interpretation, in coherent but unclaimed territory, or in conflict, whether with a theorem or with each other. It maps your position and names its costs. It does not, and cannot, tell you which position is true.
