Abstract
It is a standard view in quantum mechanics that two wave functions that differ only in the global phase represent the same physical state. In this paper, I argue that this standard view is wrong and the global phase is real in psi-ontic theories such as the de Broglie Bohm theory, the many-worlds interpretation and collapse theories of quantum mechanics.
