I don't understand what you mean. Could you explain? I'm familiar with QM, so you don't need to avoid technicality in your explanation.
Suppose we have two jars of qubits:
Half the qubits in jar (1) are in state |0> and the other half are in state |1>.
Half the qubits in jar (2) are in state |+> and the other half are in state |->.
Notice that although from a classical Bayesian MWI perspective the two jars are in very different states, there is no way to tell them apart even in principal.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
