All decohered branches are real (Many-Worlds)

Decoherence plus quantum Darwinism is sufficient to derive quasi-classical histories conforming to our experiences

Only one classical history is real; probabilities reflect ignorance

Macroscopic recoherence of distinct histories can occur

Superdeterminism underlies a single deterministic history

Sum-over-histories (path integrals) represents fundamental ontology

It is meaningless to talk about events with definite outcomes in the past when no observer observes them
34%
We need to talk about histories in a different theoretical context because quantum theory will ultimately be overthrown
34%
The past is definite; the future is not

Only consistent/decoherent histories have meaningful quantum probabilities

Objective collapse selects a single history (GRW/CSL)
Does a falling tree make a sound when no one is hearing? Is there a past event when no one is observing? What's true about histories in our (quantum) universe?
A proposition resolves when there is widespread scientific consensus about it.
Anyone can add answers.
