  It may be argued that orthodox quantum mechanics is false, and that the non-locality postulated by it does not reflect any non-locality in the quantum realm. Alternatively, it may be argued that orthodox quantum mechanics is a good instrument for predictions rather than a fundamental theory of the physical nature of the universe. On this instrumental interpretation, the predictions of quantum mechanics are not an adequate basis for any conclusion about non-locality: This theory is just an incredible oracle (or a crystal ball), which provides a very successful algorithm for predicting measurement outcomes and their probabilities, but it offers little information about ontological matters, such as the nature of objects, properties and causation in the quantum realm.
