Gribbin (1990: 253-4):
The success of the Aspect team's experiments to test the Bell inequality has eliminated all but two possible interpretations of quantum mechanics ever put forward. Either we have to accept the Copenhagen interpretation, with its ghost realities and half-dead cats, or we have to accept the Everett interpretation with its many worlds. It is, of course, conceivable that neither of the two "best buys" in the science supermarket is correct, and that both of these alternatives are wrong. There may be yet another interpretation of quantum mechanical reality which resolves all all of the puzzles that the Copenhagen interpretation and Everett interpretation resolve, including the Bell Test, and which goes beyond our present understanding — in the same way, perhaps, that general relativity transcends and incorporates special relativity. But … remember that any such "new" interpretation must explain everything that we have learned since Planck's great leap in the dark, and that it must everything as well as, or better than, the two current explanations. … we have to accept that science can at present only offer these alternatives explanations of the way the world is constructed. Neither of them seems very palatable at first sight. In simple language, either nothing is real or everything is real.

From the perspective of Systemic Functional Linguistic theory, the Copenhagen interpretation of quantum mechanics is the "best buy", provided that it includes the distinction between potential and instance, and provided that the distinction is made between experience and its construal as meaning.
On this interpretation, there are no "half-dead cats" and no "ghostly realities", and 'reality' is a property of the interpretation, the construal of experience as meaning.
