  (Note that for  Bohmian Mechanics  often viewed as an HV interpretation of QM, this statement would have  to be qualified.) [1] VD is motivated by an apparently innocuous assumption about experimental results, which is reflected in the custom of referring to quantum experiments as "measurements," namely, that these experiments reveal vales that exist independently of being measured. (Note that we do not need to assume here that the values are faithfully revealed by measurement, but only that they exist!) This suggest a second, seemingly innocuous assumption, that of noncontextuality:
