90Moral disagreement is specialPhilosophical Studies 183 (6): 1625-1650. 2026.Are disagreements about morality the same as disagreements in other domains, epistemologically speaking? This paper argues no, moral disagreement is special. In the moral domain, disagreement with a peer generates special reason to reduce confidence, whether or not this is how we should respond to peer disagreement in other domains. That is because moral disagreement distinctively generates second-personal reasons to adjust our volitional choices, which in turn exert new rational pressure on wha…Read more

1062Conspiracy StoriesCanadian Journal of Philosophy 1-19. forthcoming.We offer a novel analysis of conspiracy theorizing, according to which conspiracy theory communities are engaged in collective projects of storytelling. Other recent accounts start by analyzing individual conspiracy theorists' psychologies. We argue that a more explanatorily unifying account emerges when we start by analyzing conspiracy theorizing as a social practice. This helps us better account for conspiracy theorists' psychological heterogeneity. Some individual theorists care about uncover…Read more

492Archmedes in the lab: Can science identify good moral reasoning?In Jean-François Bonnefon & Bastien Trémolière (eds.), Moral Inferences, Routledge. pp. 155-169. 2017.Some ethicists try to settle moral disagreement by ruling out particular types of moral reasoning on the basis of cognitive scientific evidence. We argue that the cognitive science of reasoning is not well-suited to this Archimedean role. Through discussion of several influential research programs, we show that such attempts tend to either fail to be Archimedean (by assuming controversial moral views) or fail to settle disagreement (by getting caught up in unsettled debates about rationality). W…Read more

3067Generative AI systems like ChatGPT and Midjourney can produce prose or images. But can they produce art? I argue that this question, though natural and intriguing, is the wrong one to ask. A better question is this: can generative AI yield distinct or novel forms of aesthetic value? And I argue that the answer is yes. Generative AI can be used to put us in contact with the artificial sublime – a type of aesthetic value that Kant famously argues is impossible. Kant claims that sublimity (a fusion…Read more

2131Large Language Models (LLMs) like ChatGPT were trained on human conversation, but in the future they will also train us. As chatbots speak from our smartphones and customer service helplines, they will become a part of everyday life and a growing share of all the conversations we ever have. It’s hard to doubt this will have some effect on us. Here I explore a specific concern about the impact of artificial conversation on our capacity to deliberate and hold ourselves accountable to reason – that…Read more

5389Deepfakes, Deep HarmsJournal of Ethics and Social Philosophy 22 (2). 2022.Deepfakes are algorithmically modified video and audio recordings that project one person’s appearance on to that of another, creating an apparent recording of an event that never took place. Many scholars and journalists have begun attending to the political risks of deepfake deception. Here we investigate other ways in which deepfakes have the potential to cause deeper harms than have been appreciated. First, we consider a form of objectification that occurs in deepfaked ‘frankenporn’ that dig…Read more

332Doing your own research and other impossible acts of epistemic superheroismPhilosophical Psychology 36 (5): 906-930. 2023.The COVID-19 pandemic has been accompanied by an “infodemic” of misinformation and conspiracy theory. This article points to three explanatory factors: the challenge of forming accurate beliefs when overwhelmed with information, an implausibly individualistic conception of epistemic virtue, and an adversarial information environment that suborns epistemic dependence. Normally we cope with the problems of informational excess by relying on other people, including sociotechnical systems that media…Read more

64The logic of challenging research into bias and social disparityBehavioral and Brain Sciences 45. 2022.There are two problems with the logic of Cesario's argument for abandoning existing research on social bias. First, laboratory findings of decisional bias have social significance even if Cesario is right that the research strips away real-world context. Second, the argument makes overly skeptical demands of a research program seeking complex causal linkages between micro- and macro-scale phenomena.

2614Weaponized skepticism: An analysis of social media deception as applied political epistemologyIn Elizabeth Edenberg & Michael Hannon (eds.), Political Epistemology, Oxford University Press. pp. 31-48. 2021.Since at least 2016, many have worried that social media enables authoritarians to meddle in democratic politics. The concern is that trolls and bots amplify deceptive content. In this chapter I argue that these tactics have a more insidious anti-democratic purpose. Lies implanted in democratic discourse by authoritarians are often intended to be caught. Their primary goal is not to successfully deceive, but rather to undermine the democratic value of testimony. In well-functioning democracies, …Read more

20487Deepfakes and the Epistemic BackstopPhilosophers' Imprint 20 (24): 1-16. 2020.Deepfake technology uses machine learning to fabricate video and audio recordings that represent people doing and saying things they've never done. In coming years, malicious actors will likely use this technology in attempts to manipulate public discourse. This paper prepares for that danger by explicating the unappreciated way in which recordings have so far provided an epistemic backstop to our testimonial practices. Our reasonable trust in the testimony of others depends, to a surprising ext…Read more

1219Taking the Measure of Microaggression: How to Put Boundaries on a Nebulous ConceptIn Jeanine Weekes Schroer & Lauren Freeman (eds.), Microaggressions and Philosophy, Taylor & Francis. 2019.How can we tell whether an incident counts as a microaggression? How do we draw the boundary between microaggressions and weightier forms of oppression, such as hate crimes? I address these questions by exploring the ontology and epistemology of microaggression, in particular the constitutive relationship between microaggression and systemic social oppression. I argue that we ought to define microaggression in terms of the ambiguous experience that its victims undergo, focusing attention on thei…Read more

53Evolution and Moral Common SenseIn Rik Peels, Jeroen de Ridder & René van Woudenberg (eds.), Scientific Challenges to Common Sense Philosophy, Routledge. 2020.A short response to Michael Ruse's essay 'Commons Sense Morality and Its Evolutionary Underpinnings'. Argues that an evolutionary approach to ethics has difficulty accounting for the first-personal and existential aspects of moral deliberation.

1856Social media disinformation and the security threat to democratic legitimacyNATO Association of Canada: Disinformation and Digital Democracies in the 21st Century 10-14. 2019.This short piece draws on political philosophy to show how social media interference operations can be used by hostile states to weaken the apparent legitimacy of democratic governments. Democratic societies are particularly vulnerable to this form of attack because democratic governments depend for their legitimacy on citizens' trust in one another. But when citizen see one another as complicit in the distribution of deceptive content, they lose confidence in the epistemic preconditions for dem…Read more

1619Epoch Relativism and Our Moral HopelessnessIn Sophie Grace Chappell & Marcel van Ackeren (eds.), Ethics Beyond the Limits: New Essays on Bernard Williams' Ethics and the Limits of Philosophy, Routledge. pp. 168-187. 2018.When we look back upon people in past societies, such as slaveholders and colonialists, we judge their actions to have been morally atrocious. Yet we should give some thought to how the future will judge us. Here I argue that future people are likely to regard our behavior as no better than that of the past. If these future people are to be believed, then we are morally hopeless; we have little chance of working out the moral truth for ourselves. I argue that we ought to resist this conclusion, …Read more

175The Ethics of MicroaggressionRoutledge. 2020.Slips of the tongue, unwitting favoritism and stereotyped assumptions are just some examples of microaggression. Nearly all of us commit microaggressions at some point, even if we don’t intend to. Yet over time a pattern of microaggression can cause considerable harm by reminding members of marginalized groups of their precarious position. The Ethics of Microaggression is a much needed and clearly written exploration of this pervasive yet complex problem. What is microaggression and how do we k…Read more

1947Microaggression: Conceptual and scientific issuesPhilosophy Compass 15 (4). 2020.Scientists, philosophers, and policymakers disagree about how to define microaggression. Here, we offer a taxonomy of existing definitions, clustering around (a) the psychological motives of perpetrators, (b) the experience of victims, and (c) the functional role of microaggression in oppressive social structures. We consider conceptual and epistemic challenges to each and suggest that progress may come from developing novel hybrid accounts of microaggression, combining empirically tractable fea…Read more

225Contingency inattention: against causal debunking in ethicsPhilosophical Studies 177 (2): 369-389. 2020.It is a philosophical truism that we must think of others as moral agents, not merely as causal or statistical objects. But why? I argue that this follows from the best resolution of an antinomy between our experience of morality as necessarily binding on the will and our knowledge that all moral beliefs originate in contingent histories. We can address this antinomy only by understanding moral deliberation via interpersonal relationships, which simultaneously vindicate and constrains morality’s…Read more

332How to Take Offense: Responding to MicroaggressionJournal of the American Philosophical Association 4 (3): 332-351. 2018.A microaggression is a small insulting act made disproportionately harmful by its part in an oppressive pattern of similar insults. How should you respond when made the victim of a microaggression? In this paper I survey several morally salient factors, including effects upon victims, perpetrators, and third parties. I argue, contrary to popular views, that ‘growing a thicker skin’ is not good advice nor is expressing reasonable anger always the best way to contribute to confronting oppression. …Read more

317Abortion, Ultrasound, and Moral PersuasionPhilosophers' Imprint 18. 2018.We ought to treat others’ moral views with respect, even when we disagree. But what does that mean? This paper articulates a moral obligation to make ourselves open to sincere moral persuasion by others. Doing so allows us to participate in valuable relationships of reciprocal respect for agency. Yet this proposal can sound tritely agreeable. To explore its full implications, the paper applies the general obligation to one of the most challenging topics of moral disagreement: the morality of abo…Read more

2231Fake News and Partisan EpistemologyKennedy Institute of Ethics Journal 27 (S2): 43-64. 2017.Did you know that Hillary Clinton sold weapons to ISIS? Or that Mike Pence called Michelle Obama “the most vulgar First Lady we’ve ever had”? No, you didn’t know these things. You couldn’t know them, because these claims are false.1 But many American voters believed them.One of the most distinctive features of the 2016 campaign was the rise of “fake news,” factually false claims circulated on social media, usually via channels of partisan camaraderie. Media analysts and social scientists are sti…Read more

2361Psychology and the Aims of Normative EthicsIn Jens Clausen & Neil Levy (eds.), Springer Handbook of Neuroethics, Dordrecht. 2014.This chapter discusses the philosophical relevance of empirical research on moral cognition. It distinguishes three central aims of normative ethical theory: understanding the nature of moral agency, identifying morally right actions, and determining the justification of moral beliefs. For each of these aims, the chapter considers and rejects arguments against employing cognitive scientific research in normative inquiry. It concludes by suggesting that, whichever of the central aims one begins f…Read more

238Debunking debunking: a regress challenge for psychological threats to moral judgmentPhilosophical Studies 173 (3): 675-697. 2016.This paper presents a regress challenge to the selective psychological debunking of moral judgments. A selective psychological debunking argument conjoins an empirical claim about the psychological origins of certain moral judgments to a theoretical claim that these psychological origins cannot track moral truth, leading to the conclusion that the moral judgments are unreliable. I argue that psychological debunking arguments are vulnerable to a regress challenge, because the theoretical claim th…Read more

222Making Psychology Normatively SignificantThe Journal of Ethics 17 (3): 257-274. 2013.The debate between proponents and opponents of a role for empirical psychology in ethical theory seems to be deadlocked. This paper aims to clarify the terms of that debate, and to defend a principled middle position. I argue against extreme views, which see empirical psychology either as irrelevant to, or as wholly displacing, reflective moral inquiry. Instead, I argue that moral theorists of all stripes are committed to a certain conception of moral thought—as aimed at abstracting away from in…Read more
