    Should Effective Altruists Always Maximize Expected Value?
    Australasian Journal of Philosophy. forthcoming.
    Expected Value Theory is often assumed to offer the comprehensive theory of rational choice. If this is true, then rationality requires that we sometimes take enormous risks—specifically, when we are faced with options that have very low probability and very high value. This implication underpins some recent ethical views about our obligations to the extreme long-term future: consequentialist commitments to impartiality and doing the most good as efficiently as possible appear to imply that effe…Read more

    Neurodiversity and Epistemic Appraisal
    In Jonathan Dancy & Ernest Sosa Matthias Steup Kurt Sylvan (ed.), Blackwell Companion to Epistemology, Third Edition, Wiley-blackwell. 2025.
    Neurodiversity is the idea that many psychological traits commonly conceived of as deficiencies are better described merely as differences. Epistemic appraisal sorts good cognition from bad, so epistemologists should be particularly aware of when cognition that departs from the norm is different, rather than deficient. This entry gives an overview of the relevance of neurodiversity to epistemic appraisal.

    IX—Is Incoherence Always Incoherent?
    Proceedings of the Aristotelian Society 125 (2): 155-178. 2025.
    The requirements of structural rationality prohibit incoherence, but paradigmatic examples of incoherence are very diverse. Beyond an intuitive sense that incoherent attitudes do not fit together in the right way, it is difficult to characterize precisely what, if anything, unifies the paradigmatic examples. This paper offers a new analysis of incoherence based on the idea that attitudes are incoherent when they are unintelligible given the conceptual background. I argue that this analysis offer…Read more

    Neurodiversity and Attentional Normativity
    Philosophy and Phenomenological Research 111 (2): 513-531. 2025.
    We argue that some recent theories of attentional normativity license predictable misevaluations of neurodivergent cognizers. We suggest that this is because norms of attention have mostly been theorized without neuroatypical cognizers in mind. We argue that because these norms tend to focus on features that only correlate with positively evaluable cognition in neurotypical agents, they are very often false when applied to neurodivergent cognition. Additionally, we suggest that these norms licen…Read more

    Bridge Principles and Epistemic Norms
    Erkenntnis 89 (4): 1629-1681. 2022.
    Is logic normative for belief? A standard approach to answering this question has been to investigate bridge principles relating claims of logical consequence to norms for belief. Although the question is naturally an epistemic one, bridge principles have typically been investigated in isolation from epistemic debates over the correct norms for belief. In this paper we tackle the question of whether logic is normative for belief by proposing a Kripkean model theory accounting for the interaction…Read more

    I argue for the unexceptionality of evidence about what rationality requires. Specifically, I argue that, as for other topics, one’s total evidence can sometimes support false beliefs about this. Despite being prima facie innocuous, a number of philosophers have recently denied this. Some have argued that the facts about what rationality requires are highly dependent on the agent’s situation and change depending on what that situation is like (Bradley, Philosophers’ Imprint, 19(3). 2019). Others…Read more

    The value of incoherence
    Philosophical Issues 34 (1): 37-58. 2024.
    I argue that level-incoherence is epistemically valuable in a specific set of epistemic environments: those in which it is easy to acquire justified false beliefs about normative requirements of epistemic rationality. I argue that in these environments level-incoherence is the rationally dominant strategy. Nevertheless, level-incoherent combinations exhibit a distinctive tension, and this tension has been thought by many to indicate that level-incoherence is always irrational. Although this idea…Read more

    The Expanse does not provide an easy answer to the vexing question on making a decision when competing, but considering conflicts of values on the show can help us reason about tough choices in real life. Sometimes, scientific progress conflicts with the prudential value of self-preservation. This chapter explains three ways of understanding value conflicts: as situations in which every option is forbidden, situations in which every option is permissible, or situations in which some options are …Read more

    Gratuitous risk: danger and recklessness perception of adventure sports participants
    with Philip A. Ebert and Ian Durbach
    Journal of the Philosophy of Sport 51 (2): 267-284. 2024.
    Since the 1970’s there has been a major increase in adventure sports participation but it seems that engagement in such sports comes with a stigma: adventure sports participants are often regarded as reckless ‘daredevils’. We approach the questions about people’s perception of risk and recklessness in adventure sports by combining empirical research with philosophical analysis. First, we provide empirical evidence that suggests that laypeople tend to assess the danger of adventure sports as grea…Read more

    Rational belief, epistemic possibility, and the a priori
    Asian Journal of Philosophy 3 (1): 1-9. 2024.
    In this paper, I discuss Whiting’s (2021) account of rational belief and discuss some unresolved issues arising from its reliance on epistemic possibility and, by extension, perspective-relative aprioricity.

    At least you tried: The value of De Dicto concern to do the right thing
    Philosophical Studies 179 (9): 2707-2730. 2022.
    I argue that there are some situations in which it is praiseworthy to be motivated only by moral rightness de dicto, even if this results in wrongdoing. I consider a set of cases that are challenging for views that dispute this, prioritising concern for what is morally important in moral evaluation. In these cases, the agent is not concerned about what is morally important, does the wrong thing, but nevertheless seems praiseworthy rather than blameworthy. I argue that the views under discussion …Read more

    Giving Up the Enkratic Principle
    Logos and Episteme 12 (1): 7-28. 2021.
    The Enkratic Principle enjoys something of a protected status as a requirement of rationality. I argue that this status is undeserved, at least in the epistemic domain. Compliance with the principle should not be thought of as a requirement of epistemic rationality, but rather as defeasible indication of epistemic blamelessness. To show this, I present the Puzzle of Inconsistent Requirements, and argue that the best way to solve it is to distinguish two kinds of epistemic evaluation – requiremen…Read more

    Anti-Exceptionalism About Requirements of Epistemic Rationality

    De Re Significance accounts of moral appraisal consider an agent’s responsiveness to a particular kind of reason, normative moral reasons de re, to be of central significance for moral appraisal. Here, I argue that such accounts find it difficult to accommodate some neuroatypical agents. I offer an alternative account of how an agent’s responsiveness to normative moral reasons affects moral appraisal – the Reasonable Expectations Account. According to this account, what is significant for apprai…Read more

    Embracing Incoherence
    In Nick Hughes (ed.), Epistemic Dilemmas, Oxford University Press. pp. 1-29. 2021.
    Incoherence is usually regarded as a bad thing. Incoherence suggests irrationality, confusion, paradox. Incoherentism disagrees: incoherence is not always a bad thing, sometimes we ought to be incoherent. If correct, Incoherentism has important and controversial implications. It implies that rationality does not always require coherence. Dilemmism and Incoherentism both embrace conflict in epistemology. After identifying some important differences between these two ways of embracing conflict, I …Read more

    Brian Weatherson, Normative Externalism
    Philosophy 95 391-394. 2020.
    In Normative Externalism, Brian Weatherson argues that living up to one’s principles is overrated: “If one’s own principles are good, then one should conform to them. But that’s because they are good, not because they are one’s own.” (224). Weatherson argues that there is no reason to avoid being a hypocrite, or having incoherent beliefs, because Tthe first-order question of what you ought to do (or believe) is independent of the second-order question of what you ought to believe about what you …Read more

    Is it OK to Make Mistakes? Appraisal and False Normative Belief
    Dissertation, University of St Andrews. 2019.
    Sometimes we make mistakes, even when we try to do our best. When those mistakes are about normative matters, such as what is required, this leads to a puzzle. This puzzle arises from the possibility of misleading evidence about what rationality requires. I argue that the best way to solve this puzzle is to distinguish between two kinds of evaluation: requirement and appraisal. The strategy I defend connects three distinct debates in epistemology, ethics, and normativity: the debate over how our…Read more

    Can we make mistakes about what rationality requires? A natural answer is that we can, since it is a platitude that rational belief does not require truth; it is possible for a belief to be rational and mistaken, and this holds for any subject matter at all. However, the platitude causes trouble when applied to rationality itself. The possibility of rational mistakes about what rationality requires generates a puzzle. When combined with two further plausible claims – the enkratic principle, and …Read more

    Recklessness and Uncertainty: Jackson Cases and Merely Apparent Asymmetry
    Journal of Moral Philosophy 16 (4): 391-413. 2019.
    Is normative uncertainty like factual uncertainty? Should it have the same effects on our actions? Some have thought not. Those who defend an asymmetry between normative and factual uncertainty typically do so as part of the claim that our moral beliefs in general are irrelevant to both the moral value and the moral worth of our actions. Here I use the consideration of Jackson cases to challenge this view, arguing that we can explain away the apparent asymmetries between normative and factual un…Read more
