If everything is a coherent superposition evolving according to the Schrödinger equation, there is very little cancellation or unwinding of “branches” ..But also no real branching, because superposed states continued to interact.
Decoherence, in the other hand, isn’t guaranteed to leave you with more than one branch.
What is the butterfly effect mechanism?
