The Bell inequality can be derived without assuming realism, so realism is irrelevant to the issue. *> In fact, the assumption of realism is pretty meaningless because QM >> itself does not have this property -- it is intrinsically probabilistic and >> non-realist.* > > > What are you talking about?
