  Having analyzed the formal aspects of Wallace's proof of the Born rule, we
now discuss the concepts and axioms upon which it is built. Justification for
most axioms is shown to be problematic, and at times contradictory. Some of the
problems are caused by ambiguities in the concepts used. We conclude the axioms
are not reasonable enough to be taken as mandates of rationality in Everettian
Quantum Mechanics. This invalidates the interpretation of Wallace's result as
meaning it would be rational for Everettian agents to decide using the Born
rule.
