In this brief commentary, we offer thoughts on Thomas Kelly’s Bias: A Philosophical Study. We focus on the book’s relevance to the study of cognitive biases, including Kelly’s discussion of naïve realism (in the psychologists’ sense). While we are largely enthusiastic about Kelly’s theorizing, we also provide some pushback against his notion of emergent biases. We hope that psychologists will engage with Kelly’s work and might consider how some philosophical refinements could improve the empirical study of biases.

In this paper, I clarify and defend some of the central ideas of Bias in response to commentators, with a special focus on the theme of skepticism. In response to Michael Veber, I defend the project of offering a modest as opposed to an ambitious response to the skeptic. In response to Jonathan Matheson, I defend my account of the way in which bias attributions function in contexts of interpersonal disagreement, as well as the claim that an unbiased believer will (...) generally be in a stronger position to resist skeptical pressure from disagreement than a biased believer. In response to Brett Sherman, I clarify the way in which my account of bias accommodates the phenomenon of biased suspension of judgment, and I explore some of the connections between bias, suspension of judgment, and skepticism. In response to Jared Celinker and Nathan Ballantyne, I defend the possibility of emergent biases. (shrink)

The third and final part of Bias: A Philosophical Study explores the connections between bias and some of the central topics of epistemology, including knowledge, skepticism, and disagreement. It defends the possibility of biased knowing: biased believers can sometimes know, even when they believe in accordance with their biases, and even if those biases guarantee that they would believe as they do even if the truth were otherwise. It argues that the possibility of biased knowing has significant implications for both (...) philosophical methodology and traditional forms of skepticism. Extended consideration is given to the question of whether those of us who robustly favor our ordinary commonsense views over the possibilities that the skeptic calls to our attention are biased against skepticism in any objectionable sense. Finally, it critically examines our tendency to attribute bias to others in response to interpersonal disagreement and the epistemological significance of “the bias blind spot.”. (shrink)

In this paper, I examine Thomas Kelly’s account of the epistemic significance of bias presented in Bias: A Philosophical Study. Kelly draws a parallel between the skeptical threat from bias and the skeptical threat from disagreement, and crafts a response to these skeptical threats. According to Kelly, someone who is not biased can rely on that fact to conclude that their disagreeing interlocutor is biased. Kelly motivates this response by drawing several parallels to recent lessons in epistemology: that some question-begging (...) reasoning is permissible, and that there are important asymmetries between epistemological good cases and bad cases. I argue that there are several reasons to resist Kelly’s response. In brief, there are problems with each of the motivations Kelly gives for his picture. Each parallel faces significant obstacles. In addition, his response also fails to take the new evil demon intuition seriously. (shrink)

According to Thomas Kelly, traditional skeptical arguments can be conceived in terms of bias. The main aim of this paper is not to challenge Kelly’s conclusions, but rather to draw some interesting consequences from them. Specifically, in addition to cases of biased judgments, which draw the ire of the skeptic, there are also cases of biased suspension of judgment. By examining cases of racially biased suspension of judgment and comparing them to cases of skepticism, I argue that we can help (...) to uncover the mechanism that underlies the skeptic’s accusation of bias. In particular, I aim to show that it is the conclusiveness of one’s evidence, rather than the likelihood of the possibility at issue, that matters to the skeptic. (shrink)

In Bias: A Philosophical Study, Thomas Kelly offers a response to epistemological skepticism grounded in his account of bias. According to Kelly, the classic argument for skepticism is best understood as an attempt to show that our commonsense beliefs are biased against the skeptic. Kelly grants that this is true but argues that biased beliefs can still be knowledge. I offer two objections. First, if we are applying Kelly’s theory of bias to skepticism, it is best to think of the (...) skeptic’s challenge to be that our anti-skeptical beliefs are based on what we know to be biased reasons. Kelly has not shown that this sort of bias is compatible with knowledge. Second, Kelly’s approach to the problem of skepticism is an example of what I have called “unambitious epistemology.” And, for that reason, it is not a satisfactory answer to skepticism. (shrink)

I have developed transcendental arguments to refute several versions of Nick Bostrom’s simulation hypothesis. I called some of these arguments the SIM-style argument. In this paper, I have four main aims. First, I employ the SIM-style argument to remedy a defect in Hilary Putnam’s Brain-in-vat argument. Second, I show that the most radical skepticism, which Tim Button called the nightmarish Cartesian skepticism, can be refuted by the SIM-style argument or by another transcendental argument I develop here. Third, I compare my (...) approach to radical skepticisms with Donald Davidson’s, as it is often regarded as an exemplar of transcendental arguments. Fourth, I explain how the prominent objections, mainly developed by Barry Stroud, to transcendental arguments can incur two undesirable results: psychologism and Kantian skepticism. (shrink)

Problems for Moral Debunkers : On the Logic and Limits of Empirically Informed Ethics, written by Peter Königs.

The aim of this paper is to strike a blow for the relevance of the debasing demon originally summoned by Jonathan Schaffer. I do so by, first, defending this skeptical hypothesis against critics and, second, by noting important similarities between the workings of this demon and implicit bias. Along the way, I elucidate the structure of this skeptical argument by comparing it to other better-known skeptical arguments. I also clarify the kinds of access the debasing skeptical scenario, as well as (...) some of the replies, operate with. Apart from being interesting in its own right as a different skeptical challenge, the debasing demon raises important issues regarding bias, as I will show by using an example from epistemic decolonialization.

This paper presents Hegel’s criticism of two central ideas of Pyrrhonism: the importance of stating only how things appear and Pyrrhonism as a way of life. After providing a sketch of the main features of Pyrrhonism, the paper lays out and critically evaluates Hegel’s largely unexamined argument against Pyrrhonism in his early 1802 essay on skepticism. Hegel claims that the Pyrrhonist’s appeal to appearance renders Pyrrhonism philosophically vacuous: insofar as Pyrrhonism merely describes the subjective contents of the Pyrrhonist’s mind, it (...) has no philosophical import. Sextus would not accept Hegel’s criticism because the appeal to appearance could express the provisional rather than purely subjective character of Pyrrhonism. The paper proceeds by examining Hegel’s argument in the Phenomenology that skepticism is contradictory on account of conjoining suspension of judgment with acquiescing in appearances as the guide to life. Sextus would reject Hegel’s criticism by insisting on the distinction between judgment and appearance. (shrink)

In this article, evidence is briefly presented for three facts that together point to something puzzling. (1) That major continental philosophers of the nineteenth century tended to engage in some detail, as part of a broader preoccupation with ancient Greek thought, with Pyrrhonian scepticism. (2) That major continental philosophers of the twentieth century tended to engage in some depth with their nineteenth-century forebears and maintained their tendency to engage significantly with ancient Greek thought. (3) That twentieth-century continental philosophers demonstrate little (...) to no interest in Pyrrhonian scepticism. This raises the question: why does engagement with Pyrrhonism disappear from continental philosophy? The article discusses two hypotheses that might explain this disappearance. (shrink)

Pinillos’ Why We Doubt presents a powerful critique of such global skeptical assertions as “I don’t know I am not a brain-in-a-vat (biv)” by introducing a cognitive mechanism that is sensitive to error possibilities and a Bayesian rule of rationality that this mechanism is designed to approximate. This multifaceted argument offers a novel counter to global skepticism, contending that our basis for believing such premises is underminable. In this work, we engage with Pinillos’ adoption of Bayesianism, questioning whether the Bayesian (...) principle that he invokes truly does fail to generate the verdict that we don’t we aren’t biv s, contrary to what Pinillos asserts. Furthermore, we argue that Pinillos’ empirical argument is not empirical enough; we need a lot more empirical work if we are going to counter global skepticism and win over neutral bystanders.

In Outlines of Skeptical-Dogmatism, Mark Walker argues for Skeptical-Dogmatism about philosophical views—i.e., he argues that we should disbelieve most philosophical views. Walker argues for Skeptical-Dogmatism over both Dogmatism and Skepticism. In response, I defend Skepticism—i.e., the view that we should neither believe nor disbelieve most philosophical views. I argue that Walker’s arguments overlook some of the most plausible forms of philosophical Skepticism where the Skeptic suspends judgment about most disputed philosophical views without assigning a credence of 0.5 to those views. (...) In doing so, I argue that suspension of judgment is the default justified doxastic attitude—i.e., the doxastic attitude one is epistemically justified in adopting absent any reason to do otherwise. I also champion Skepticism by offering modified versions of some of Walker’s thought experiments, posing challenges for Skeptical-Dogmatism, and arguing that Skepticism and Skeptical-Dogmatism share some common benefits.

Ángel Pinillos’ Why We Doubt offers an error theory for at least some versions of global skepticism: skeptical doubts are based on a faulty heuristic. Once this heuristic is replaced by a more apt principle inspired by Bayesian approaches to epistemology, the skeptical doubts are shown not to be motivated. I argue contra Pinillos that skeptical doubts may remain even if we grant the main line of Pinillos’ argument. Skeptical doubts might be generated by disagreement even when we accept Pinillos’ (...) Bayesian inspired principle. (shrink)
