Here is a short somewhat speculative paper of mine on the many worlds
interpretation.

When Worlds Collide: Quantum Probability From Observer Selection?
by Robin Hanson
Deviations from exact decoherence make little difference for large-amplitude
quantum states, but can make a big difference for small-amplitude states.
This may provide a rationale for ignoring small-amplitude states when
deriving the Born measurement probabilities from the many worlds
interpretation. Interactions between large and small worlds may erase the
memory of observers in small amplitude worlds.
