In this article I defend the Doomsday Argument, the Halfer Position in Sleeping Beauty, the Fine-Tuning Argument, and the applicability of Bayesian confirmation theory to the Everett interpretation of quantum mechanics. I will argue that all four problems have the same structure, and I give a unified treatment that uses simple models of the cases and no controversial assumptions about confirmation or self-locating evidence. I will argue that the troublesome feature of all these cases is not self-location but selection effects.
