In the book "A Briefer History of Time" Stephen Hawking wrote:
The unpredictable, random element comes in only when we try to interpret the wave in terms of the positions and velocities of particles. But maybe that is our mistake: maybe there are no particle positions and velocities, but only waves. It is just that we try to fit the waves to our preconceived ideas of positions and velocities. The resulting mismatch is the cause of the apparent unpredictability.
Are there evidences that disprove this hypothesis?
If true, would it eliminate most of the apparent quantum paradoxes, and necessity to "Shut up and calculate!" for those who attempt to interpret quantum physics with common sense?
Edit: I assume that S. Hawking is aware of Standard Model, and he considers this statement as a legitimate hypothesis. Are there evidences that prove that it's not? In other words, is it a philosophical or scientific question?
