Taboo “justification”. Justification is essentially a pointer to evidence or inference. After all the inference is said and done, the person who needs to provide more evidence is the person who has the more un-parsimonious hypothesis. You reject fairies based on a lack of justification because it’s not parsimonious. You can’t reject Many-Worlds on those same grounds, at least not without explaining more.
The difference is that the fairies interpretation of raindrops has different maths than the non-fairy interpretation of raindrops. When the mathematically-rigorous descriptions for two different hypotheses are different, there is a clear correct answer as to which is more parsimonious.
Many-worlds has exactly the same mathematical description as the alternative, so it’s hard to say which is more parsimonious. You can’t say that Single-World is default and Many Worlds requires justification. This is why I claim that it is first a question of ontology (a question of what we choose to define as reality), and then maybe we can talk about the epistemology and whether or not the statement is “True” within our definitions...after we clarify our ontology and define the relationship between ontology and parsimony, not before.
