Noname manuscript No. (will be inserted by the editor) A Dutch Book against Sleeping Beauties Who Are Evidential Decision Theorists

the date of receipt and acceptance should be inserted later Abstract In the context of the Sleeping Beauty problem, it has been argued that so-called “halfers ” can avoid Dutch book arguments by adopting eviden-tial decision theory. I introduce a Dutch book for a variant of the Sleeping Beauty problem and argue that evidential decision theorists fall prey to it, whether they are halfers or thirders. The argument crucially requires that an action can provide evidence for what the agent would do not only at other de-cision points where she has exactly the same information, but also at decision points where she has different but “symmetric ” information
