The claim is that each measurement reveals a property that the particle already possessed. The article then goes on to say that no single trial can measure the quantity of interest, so they consider the average over many trials, or the expectation value. Unfortunately for the writer of the article, the quantum expectation value does not depend on the physical properties existing independently of being observed or measured. So the assumption of realism is completely spurious. Wikipedia is not a reliable source......
