    Extracting Money From Causal Decision Theorists.Caspar Oesterheld & Vincent Conitzer - 2021 - Philosophical Quarterly 71 (4):pqaa086.
    Newcomb’s problem has spawned a debate about which variant of expected utility maximisation should guide rational choice. In this paper, we provide a new argument against what is probably the most popular variant: causal decision theory. In particular, we provide two scenarios in which CDT voluntarily loses money. In the first, an agent faces a single choice and following CDT’s recommendation yields a loss of money in expectation. The second scenario extends the first to a diachronic Dutch book against CDT.

    A Dutch Book Against Sleeping Beauties Who Are Evidential Decision Theorists.Vincent Conitzer - 2015 - Synthese 192 (9):2887-2899.
    In the context of the Sleeping Beauty problem, it has been argued that so-called “halfers” can avoid Dutch book arguments by adopting evidential 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 decision points where she has exactly the (...)

    A Devastating Example for the Halfer Rule.Vincent Conitzer - 2015 - Philosophical Studies 172 (8):1985-1992.
    How should we update de dicto beliefs in the face of de se evidence? The Sleeping Beauty problem divides philosophers into two camps, halfers and thirders. But there is some disagreement among halfers about how their position should generalize to other examples. A full generalization is not always given; one notable exception is the Halfer Rule, under which the agent updates her uncentered beliefs based on only the uncentered part of her evidence. In this brief article, I provide a simple (...)

    A Puzzle About Further Facts.Vincent Conitzer - 2019 - Erkenntnis 84 (3):727-739.
    In metaphysics, there are a number of distinct but related questions about the existence of “further facts”—facts that are contingent relative to the physical structure of the universe. These include further facts about qualia, personal identity, and time. In this article I provide a sequence of examples involving computer simulations, ranging from one in which the protagonist can clearly conclude such further facts exist to one that describes our own condition. This raises the question of where along the sequence the (...)

    Can Rational Choice Guide Us to Correct de Se Beliefs?Vincent Conitzer - 2015 - Synthese 192 (12):4107-4119.
    Significant controversy remains about what constitute correct self-locating beliefs in scenarios such as the Sleeping Beauty problem, with proponents on both the “halfer” and “thirder” sides. To attempt to settle the issue, one natural approach consists in creating decision variants of the problem, determining what actions the various candidate beliefs prescribe, and assessing whether these actions are reasonable when we step back. Dutch book arguments are a special case of this approach, but other Sleeping Beauty games have also been constructed (...)

    Which Features of Patients Are Morally Relevant in Ventilator Triage? A Survey of the UK Public.Walter Sinnott-Armstrong, Hazem Zohny, Julian Savulescu, Dominic Wilkinson, Vincent Conitzer, Jana Schaich Borg & Lok Chan - 2022 - BMC Medical Ethics 23 (1):1-14.
    BackgroundIn the early stages of the COVID-19 pandemic, many health systems, including those in the UK, developed triage guidelines to manage severe shortages of ventilators. At present, there is an insufficient understanding of how the public views these guidelines, and little evidence on which features of a patient the public believe should and should not be considered in ventilator triage.MethodsTwo surveys were conducted with representative UK samples. In the first survey, 525 participants were asked in an open-ended format to provide (...)

    On Stackelberg Mixed Strategies.Vincent Conitzer - 2016 - Synthese 193 (3):689-703.
    It is sometimes the case that one solution concept in game theory is equivalent to applying another solution concept to a modified version of the game. In such cases, does it make sense to study the former separately, or should we entirely subordinate it to the latter? The answer probably depends on the particular circumstances, and indeed the literature takes different approaches in different cases. In this article, I consider the specific example of Stackelberg mixed strategies. I argue that, even (...)
