    Most ethical guidelines on AI tout algorithmic transparency, the openness of an algorithm’s inner workings to human scrutiny, as an important desideratum in algorithmic deployment. Algorithmic transparency has been touted as important for valuable goals like procedural fairness, AI trustworthiness, contestability and planning around AI decision-making. This paper argues that these goals are better served by a distinct desideratum, algorithmic justifiability, the ability of an algorithm to provid…Read more

    In a number of policy, institutional, activist and advocacy contexts, attributing bias to an algorithm does not just describe the algorithm but also imposes a particular, normatively laden conception of bias on others. Given the normative content of such bias attributions, this would involve making moral demands on others to rectify the algorithm, compensate the victims of such bias and/or not unselectively deploy the algorithm. It is also the case that moral demands, especially in the above‐men…Read more

    Researchers and Institutional Review Board members often disagree about the permissibility of some parts or all of the former’s proposed research. At least sometimes, this disagreement is reasonable. This is often because there are competing values and no clear solution as to how to balance these values. Arguably, given that there are multiple reasonable ways in which these values might be balanced, IRBs are subject to an asymmetric public justification requirement. This requirement implies that…Read more

    Solones, Solo Reproduction and Vice
    Asian Bioethics Review 18 (2): 471-487. 2026.
    In vitro gametogenesis (IVG) is a technology that allows the creation of gametes from stem cells. Given that IVG makes possible the production of cross-sex gametes, IVG, if successful, can, among other uses, allow a single person to solo reproduce (i.e. have children without a sperm or egg donor). This would involve using IVG to produce one cross-sex gamete and fusing that gamete with a same-sex gamete which is either artificially or naturally derived from the same person. Because solo reproduct…Read more

    Trust as a Moral Power
    Kennedy Institute of Ethics Journal. forthcoming.
    On extant accounts of trust, it is not apt to trust someone who seems or actually is untrustworthy. It also does not seem apt, on such accounts, to morally demand trust and blame people for not trusting. Yet, there seem to be cases where it is plausible that trusting the untrustworthy might be apt or where we might aptly demand trust and blame people for not trusting. In this paper, we sketch out an account of trust according to which to trust someone involves exercising a moral power which giv…Read more

    Against Public‐Facing Religious Bio‐Restrictionism
    Bioethics 39 (9): 810-820. 2025.
    Recent calls to include religious bioethics on the table in policy and other public‐facing contexts have been made on the grounds of respect. This paper argues that these same considerations of respect point to an obligation to exclude religious bioethics from public‐facing contexts. This is because public‐facing religious bioethics is typically bio‐restrictionist in orientation and thus involves making demands on others that people could reasonably disagree with. At the same time, respect for p…Read more

    Permissivism and Mismatched Granularity
    Australasian Journal of Philosophy. 2025.
    Permissivism is the claim that more than one doxastic attitude towards a proposition can at least sometimes be justified by the same total body of evidence. Impermissivism, the negation of Permissivism, is commonly taken to involve evidentialist assumptions. The only versions of Permissivism consistent with evidentialist assumptions are those which combine coarse-grained accounts of doxastic attitudes with fine-grained accounts of evidential support, as with Blake Roeber’s equipollent cases or v…Read more

    A significant and important ethical tension in resource allocation and public health ethics is between utility and equity. We explore this tension between utility and equity in the context of health AI through an examination of a diagnostic AI screening tool for diabetic retinopathy developed by a team of researchers at Duke-NUS in Singapore. While this tool was found to be effective, it was not equally effective across every ethnic group in Singapore, being less effective for the minority Malay…Read more

    AI and the need for justification (to the patient)
    Ethics and Information Technology 26 (1): 1-12. 2024.
    This paper argues that one problem that besets black-box AI is that it lacks algorithmic justifiability. We argue that the norm of shared decision making in medical care presupposes that treatment decisions ought to be justifiable to the patient. Medical decisions are justifiable to the patient only if they are compatible with the patient’s values and preferences and the patient is able to see that this is so. Patient-directed justifiability is threatened by black-box AIs because the lack of rat…Read more

    Ageing populations are increasing across the world. Many countries are exploring new ways to provide care for the elderly in hospitals, community care and family household settings. Scientific progress in robotics, artificial intelligence integrated systems and increasingly sophisticated software engineering have contributed to innovative developments in care robots in the Asia Pacific regions, Europe and the US. Whilst the use of care robots is not widespread, research is already occurring to i…Read more

    Political Liberalism and Reasonable Disagreement
    Social Theory and Practice 49 (1): 131-160. 2023.
    On the standard version of political liberalism, the exercise of political power is legitimate only if it is justifiable to all reasonable persons. Correspondingly, reasonable disagreement about the moral doctrines underlying a law makes that law not justifiable to all reasonable persons. In this paper, I argue that political liberals are committed to understanding reasonable disagreement as being rational, rather than praiseworthy disagreement between morally reasonable person because other con…Read more

    Institutional Review Boards and Public Justification
    Ethical Theory and Moral Practice 26 (3): 405-423. 2022.
    Ethics committees like Institutional Review Boards and Research Ethics Committees are typically empowered to approve or reject proposed studies, typically conditional on certain conditions or revisions being met. While some have argued this power should be primarily a function of applying clear, codified requirements, most institutions and legal regimes allow discretion for IRBs to ethically evaluate studies, such as to ensure a favourable risk-benefit ratio, fair subject selection, adequate inf…Read more

    The development of some COVID-19 vaccines by private companies like Moderna and Sanofi-GSK has been substantially funded by various governments. While the Sanofi CEO has previously suggested that countries that fund this development ought to be given some priority, this suggestion has not been taken seriously in the literature. Considerations of nationalism, sustainability, need, and equitability have been more extensively discussed with respect to whether and how much a country is entitled to a…Read more

    Permissivism and self-fulfilling propositions
    Ratio 34 (3): 217-226. 2021.
    Recently, self-fulfilling cases, that is, ones in which an agent's believing a proposition guarantees its truth, have been offered as counterexamples to uniqueness. According to uniqueness, at most one doxastic attitude is epistemically rational given the evidence. I argue that self-fulfilling cases are not counterexamples to uniqueness because belief-formation is not governed by epistemic rationality in such cases. Specifically, this is because epistemic rationality is not just about forming tr…Read more

    Political liberalism and epistemic permissivism
    Dissertation, University of Warwick. 2019.
    The supposed fact of reasonable disagreement plays a crucial role in standard accounts of political liberalism. The standard account posits reasonable disagreement as arising primarily from the supposed fact that, in at least some circumstances, people can permissibly respond in different ways to the same evidence. That is to say, the standard account presupposes permissivism: It is possible that more than one doxastic attitude towards a proposition is rationally permissible, given a body of evi…Read more

    Exploring the boundaries of autonomy and the 'right' to access innovative stem cell therapies
    with Tamra Lysaght and Bernadette Richards
    Asian Bioethics Review 9 (1-2): 45-60. 2017.
    Demands for improved access to innovative therapies have prompted a discourse that claims patients have rights to access treatments that may be of benefit, even if evidence that demonstrates safety and efficacy is lacking. This rights-based discourse is grounded in accounts of autonomy and assertions claiming that the state ought to not interfere with the free choices of patients and clinical decision-making. In this essay, we scrutinise these arguments to defend the ethical and legal permissibi…Read more

    Defending the Uniqueness Thesis - A Reply to Luis Rosa
    Logos and Episteme 6 (1): 129-139. 2015.
    The Uniqueness Thesis (U), according to Richard Feldman and Roger White, says that for a given set of evidence E and a proposition P, only one doxastic attitude about P is rational given E. Luis Rosa has recently provided two counterexamples against U which are supposed to show that even if there is a sense in which choosing between two doxastic attitudes is arbitrary, both options are equally and maximally rational. Both counterexamples work by exploiting the idea that ‘ought implies can’ and t…Read more
