And back again with a strange/odd layman question: Actually, this remark of Jilang is a perfect illustration of what I am wondering about: It seems as if realism and locality are behaving like two eigenstates in a space of interpretations of QM. Most people seem to suggest that you must have either one or the other. However, does that make sense if both are possible? Could there be a space in which, depending on the set of measurements and/or experimental setup, there is a mixture of degrees to which two or more interpretations form an explanation of the experimental outcome? Most scientifically educated forum members seem to suggest interpretations are not the field of QM. If that is the case, please let me know. I am not asking this odd question because I suggest I have any anwer to anything. I have just been wondering about exactly this for a long time! It is an insight in my strange world of thought! I hope someone can pinpoint where I am mistaking (probably everyone ). Thanks! UPDATE: In fact, forget the notion of eigenvalues. Is it possible that certain experiments can be interpreted by a mixture of degrees of mutually exclusive interpretations? (I imagine aspects of the experimental setup determine the values of the degrees - so the experimental setup is part of the definition of the interpretation of the experiment and its outcomes. In other words: the experimental setup is the definition of the interpretation of it; that we can have different interpretations doesn't necessarily have to mean that interpretations can't be combined. I could rephrase this in: of which is realism or locality the property? ).
