Quantum mechanics is definitely not immune, that's where we should see the manifestation of the bias I'm proposing. When I refer to Everett many words I'm referring specifically to the property of it where an observer "branches" into multiple successor observers (which I extend to include branches where there are no successor observers).

But which laws would be affected and which would not, I'm not at all certain. It could be some, or all (or, of course, none, if I'm wrong). My proposal is to use this sort of reasoning to develop "deeper" fundamental laws.
