Yes this is the formal point of view of the quantum results
measurements. However, this does not explain the selection of the
eingenbasis used to match the computed results with the experimental
results.
In other words, for the collapse postulate, every eigenbasis is ok to
express statistical results (the born rules), but in the lab, we just
have one basis where the statistics apply. Why?

Seratend.

(and please do not use the decoherence as the way to solve this issue)
