This question applies to any type of multiverse or many worlds that translates or actualizes each of a set of potentials into a separate universe. These potentials may come from quantum randomness or cosmological fine-tuning or something similar.
The “desperate” adjective is deliberate. I am asking if taking a multiverse approach to randomness implies science has given up on finding an explanation for the randomness, that is, there is a suspicion that an explanation cannot exist and the multiverse offers no other help in explaining the original randomness.
The “agency” is deliberate. A random event could be viewed as some type of agent making a choice. I am aware of theistic arguments for God using fine-tuning, but the agents I am concerned with are more general. They need not be divine, but could be, say, a system of electrons or what Whitehead might describe as organisms.
To limit scope, I am not concerned about a multiverse that is posited to get an infinite number of universes because ours appears finite in some way. That idea of a multiverse is not a translation of potentialities into actualized universes to remove the potentialities from consideration. It is just the idea that given the existence of our universe there may be many other universes similar to our own.
Also, I am not concerned with the more general principle of plenitude although in this case all possibilities are also actualized. The multiverse ideas I am interested in seem to be offered to eliminate the possibility for agents to be actualized. They seem to me motivated more by a principle of parsimony at least with regards to possible agents.
My suspicion is the answer is “yes”. I am looking for references to those who have already developed this idea or to “no” answers that would counter my suspicions. If the answer is “no”, what does a multiverse explain besides an interest in removing agency?
