How many percentage of physicists believe Copenhagen is pragmatism and how many percentage believe Copenhagen is actual in that the particles attributes are really nonexistent before measurement? Quoting Herbert in Quantum Reality: "Some physicists confuse the Copenhagen doctrine with a pragmatic interpretation of quantum theory. The pragmatist regards any theory as mere mathematical machine for generating numbers which he then compares with experiment. A pragmatist is concerned with results, not reality. The pragmatist refuses on principle to speculate about deep reality, such a concept being meaningless from his point of view. Pragmatism is an intellectually safe but ultimately sterile philosphy. A pragmatist would refuse on principle to comment on the existential status of an unmeasured electron's attributes. No timid pragmatists, there students of Bohr! The Copenhagenists claim not that such attributes are meaningless but they are nonexistent. They based their conclusions about an unseen quantum reality not on some abstract philosophical principle applicable in all cases but on the specific structure of quantum theory itself. Some theories of the world (Newtonian mechanics, for instance) allow us to believe or not that unobserved entities possess their own attributes. Quantum theory, according to the followers of Bohr, does not permit this option."
