    Do You Know More When It Matters Less?
    with Adam Feltz
    Philosophical Psychology 23 (5). 2010.
    According to intellectualism, what a person knows is solely a function of the evidential features of the person's situation. Anti-intellectualism is the view that what a person knows is more than simply a function of the evidential features of the person's situation. Jason Stanley (2005) argues that, in addition to “traditional factors,” our ordinary practice of knowledge ascription is sensitive to the practical facts of a subject's situation. In this paper, we investigate this question empirica…Read more

    Causation, norms, and omissions: A study of causal judgments
    with Randolph Clarke, Joshua Shepherd, John Stigall, and Robyn Repko Waller
    Philosophical Psychology 28 (2): 279-293. 2015.
    Many philosophical theories of causation are egalitarian, rejecting a distinction between causes and mere causal conditions. We sought to determine the extent to which people's causal judgments discriminate, selecting as causes counternormal events—those that violate norms of some kind—while rejecting non-violators. We found significant selectivity of this sort. Moreover, priming that encouraged more egalitarian judgments had little effect on subjects. We also found that omissions are as likely …Read more

    By making plausible the Diversity Thesis (different people have systematically different and incompatible packages of epistemic intuitions), experimental epistemology raises the specter of the shifting-sands problem: the evidence base for epistemology contains systematic inconsistencies. In response to this problem, some philosophers deny the Diversity Thesis, while others flirt with denying the Evidence Thesis (in normal circumstances, the epistemic intuition that p is prima facie evidence that…Read more

    The moral enhancement of humans by biological or genetic means has recently been urged as a response to the pressing concerns facing human civilization. In this paper, I argue that proponents of biological moral enhancement have misrepresented the facts of human moral psychology. As a result, the likely effectiveness of traditional methods of moral enhancement has been underestimated, relative to biological or genetic means. I review arguments in favor of biological moral enhancement and argue t…Read more

    Recently, a number of philosophers and psychologists have drawn on neuroscientific and psychological research on the role of affective processes in moral thinking to provide support for moral sentimentalism. Philip Gerrans and Jeanette Kennett criticize such ‘neurosentimentalist’ accounts on the grounds that they focus only on synchronic processes occurring at the time of moral judgement. As a result, these accounts face a dilemma: either they fail to accommodate the connection between moral jud…Read more

    Michael Smith, Rationalism, And The Moral Psychology Of Psychopathy
    Florida Philosophical Review 7 (1): 1-15. 2007.
    In this paper, on the basis of psychological research concerning psychopathy, I argue against one claim a moral rationalist—such as Michael Smith —might make. First, I distinguish three rationalist claims the moral rationalist might make: the rationalists' conceptual claim, the rationalists' substantial claim, and the practicality requirement. Then, I go on to discuss some of the subtle relations between these claims. I argue that, if we have reason to reject the rationalists' substantial claim,…Read more
