Ok... despite what you may have heard.... randomness is NOT a fundamental feature of a statistical nature of any wave function. This may seem like big leap, but based on what we actually know, we realise we know nothing. Some have taken this to mean we have model of randomness... this alone is a disgusting line of investigation that has already determined by logic. The wave function was never an indication of statistical ''randomness.'' But rather.. an indication we can only have a limited amount of information from a system.
