  1. Intertheoretic Value Comparison: A Modest Proposal.Christian Tarsney - 2018 - Journal of Moral Philosophy 15 (3):324-344.
    In the growing literature on decision-making under moral uncertainty, a number of skeptics have argued that there is an insuperable barrier to rational "hedging" for the risk of moral error, namely the apparent incomparability of moral reasons given by rival theories like Kantianism and utilitarianism. Various general theories of intertheoretic value comparison have been proposed to meet this objection, but each suffers from apparently fatal flaws. In this paper, I propose a more modest approach that aims to identify classes of (...)

  2. Moral Uncertainty for Deontologists.Christian Tarsney - 2018 - Ethical Theory and Moral Practice 21 (3):505-520.
    Defenders of deontological constraints in normative ethics face a challenge: how should an agent decide what to do when she is uncertain whether some course of action would violate a constraint? The most common response to this challenge has been to defend a threshold principle on which it is subjectively permissible to act iff the agent's credence that her action would be constraint-violating is below some threshold t. But the threshold approach seems arbitrary and unmotivated: what would possibly determine where (...)

  3. Metanormative Regress: An Escape Plan.Christian Tarsney - manuscript
    How should you decide what to do when you're uncertain about basic normative principles (e.g., Kantianism vs. utilitarianism)? A natural suggestion is to follow some "second-order" norm: e.g., "comply with the first-order norm you regard as most probable" or "maximize expected choiceworthiness". But what if you're uncertain about second-order norms too -- must you then invoke some third-order norm? If so, it seems that any norm-guided response to normative uncertainty is doomed to a vicious regress. In this paper, I aim (...)

  4. Exceeding Expectations: Stochastic Dominance as a General Decision Theory.Christian Tarsney - manuscript
    The principle that rational agents should maximize expected utility or choiceworthiness is intuitively plausible in many ordinary cases of decision-making under uncertainty. But it is less plausible in cases of extreme, low-probability risk (like Pascal's Mugging), and intolerably paradoxical in cases like the St. Petersburg and Pasadena games. In this paper I show that, under certain conditions, stochastic dominance reasoning can capture most of the plausible implications of expectational reasoning while avoiding most of its pitfalls. Specifically, given sufficient background uncertainty (...)

  5. Rationality and Moral Risk: A Moderate Defense of Hedging.Christian Tarsney - 2017 - Dissertation, University of Maryland
    How should an agent decide what to do when she is uncertain not just about morally relevant empirical matters, like the consequences of some course of action, but about the basic principles of morality itself? This question has only recently been taken up in a systematic way by philosophers. Advocates of moral hedging claim that an agent should weigh the reasons put forward by each moral theory in which she has positive credence, considering both the likelihood that that theory is (...)

    Future Bias in Action: Does the Past Matter More When You Can Affect It?Andrew James Latham, Kristie Miller, James Norton & Christian Tarsney - forthcoming - Synthese:1-23.
    Philosophers have long noted, and empirical psychology has lately confirmed, that most people are ‘biased toward the future’: we prefer to have positive experiences in the future, and negative experiences in the past. At least two explanations have been offered for this bias: (i) belief in temporal passage (or related theses in temporal metaphysics) and (ii) the practical irrelevance of the past resulting from our inability to influence past events. We set out to test the latter explanation. In a large (...)

  7. Average Utilitarianism Implies Solipsistic Egoism.Christian Tarsney - manuscript
    Average utilitarianism and several related axiologies, when paired with the standard expectational theory of decision-making under risk and with reasonable empirical credences, can find their practical prescriptions overwhelmingly determined by the minuscule probability that the agent assigns to solipsism -- i.e., to the hypothesis that there is only one welfare subject in the world, viz., herself. This either (i) constitutes a reductio of these axiologies, (ii) suggests that they require bespoke decision theories, or (iii) furnishes a novel argument for ethical (...)

    Non-Additive Axiologies in Large Worlds.Christian Tarsney & Teruji Thomas - manuscript
    Is the overall value of a world just the sum of values contributed by each value-bearing entity in that world? Additively separable axiologies (like total utilitarianism, prioritarianism, and critical level views) say 'yes', but non-additive axiologies (like average utilitarianism, rank-discounted utilitarianism, and variable value views) say 'no'. This distinction is practically important: additive axiologies support 'arguments from astronomical scale' which suggest (among other things) that it is overwhelmingly important for humanity to avoid premature extinction and ensure the existence of a (...)

  9. The Epistemic Challenge to Longtermism.Christian Tarsney - manuscript
    Longtermism holds that what we ought to do is mainly determined by effects on the far future. A natural objection is that these effects may be nearly impossible to predict -- perhaps so close to impossible that, despite the astronomical importance of the far future, the expected value of our present options is mainly determined by short-term considerations. This paper aims to precisify and evaluate (a version of) this epistemic objection. To that end, I develop two simple models for comparing (...)

  10. Vive la Différence? Structural Diversity as a Challenge for Metanormative Theories.Christian Tarsney - forthcoming - Ethics.
    Decision-making under normative uncertainty requires an agent to aggregate the assessments of options given by rival normative theories into a single assessment that tells her what to do in light of her uncertainty. But what if the assessments of rival theories differ not just in their content but in their structure -- e.g., some are merely ordinal while others are cardinal? This paper describes and evaluates three general approaches to this "problem of structural diversity": structural enrichment, structural depletion, and multi-stage (...)
