Doesn't a mixed state satisfy the Ignorance Interpretation by definition? Concerning a pure state, does it negate the Ignorance Interpretation because it's a linear combination of pure state vectors in some Hilbert Space?
Brent was emphatic, writing "exactly wrong" that a pure state, presumably represented as a linear sum of pure basis states, could be interpreted by the Ignorance Interpretation. But he hasn't proven that, or given a link which does. Quentin, OTOH, offered an example to show that a pure state could not be interpreted as satisfying the Ignorance Interpretation, but his example had a typo near the beginning which he hasn't corrected, so I gave up on his example. So, what is the status of the Ignorance Interpretation for mixed and pure states, and why is that the case.
