the post anthropics and the universal distribution (recommended dependencies: 1, 2, 3, 4, 5) tries to unify anthropics with the notion of a universal distribution (whether that be solomonoff prior or what i'll call the "levin prior") by splitting hypotheses about a reasoner's location among the set of possible worlds as a "world and claw" pair. the "world" part is the hypothesis program as to what world you inhabit, as opposed to counterfactual worlds, and the "claw" part is a program that locates you within that world.
