All probability is actually subjective. Uncertainty and randomness are subjective. If you don't know what the outcome's going to be, so ourolodize, that's because you individually do not know. It's not because there is uncertainty there deeply in the universe. What we know about quantum theory is that all physic possible things occur. And rather than refute all the failed ways of trying to understand quantum theory, we're just going to take seriously what the equations of quantum theory say.
