Humans massively depend on communication with others, but this leaves them open to the risk of being accidentally or intentionally misinformed. To ensure that, despite this risk, communication remains advantageous, humans have, we claim, a suite of cognitive mechanisms for epistemic vigilance. Here we outline this claim and consider some of the ways in which epistemic vigilance works in mental and social life by surveying issues, research and theories in different domains of philosophy, linguistics, cognitive psychology and the social sciences.

I argue that psychology and epistemology should posit distinct cognitive attitudes of religious credence and factual belief, which have different etiologies and different cognitive and behavioral effects. I support this claim by presenting a range of empirical evidence that religious cognitive attitudes tend to lack properties characteristic of factual belief, just as attitudes like hypothesis, fictional imagining, and assumption for the sake of argument generally lack such properties. Furthermore, religious credences have distinctive properties of their own. To summarize: factual beliefs (...) are practical setting independent, cognitively govern other attitudes, and are evidentially vulnerable. By way of contrast, religious credences have perceived normative orientation, are susceptible to free elaboration, and are vulnerable to special authority. This theory provides a framework for future research in the epistemology and psychology of religious credence. (shrink)

There is a robust scientific consensus concerning climate change and evolution. But many people reject these expert views, in favour of beliefs that are strongly at variance with the evidence. It is tempting to try to explain these beliefs by reference to ignorance or irrationality, but those who reject the expert view seem often to be no worse informed or any less rational than the majority of those who accept it. It is also tempting to try to explain these beliefs (...) by reference to epistemic overconfidence. However, this kind of overconfidence is apparently ubiquitous, so by itself it cannot explain the difference between those who accept and those who reject expert views. Instead, I will suggest that the difference is in important part explained by differential patterns of epistemic deference, and these patterns, in turn, are explained by the cues that we use to filter testimony. We rely on cues of benevolence and competence to distinguish reliable from unreliable testifiers, but when debates become deeply politicized, asserting a claim may itself constitute signalling lack of reliability.

Beliefs serve at least two broad functions. First, they help us navigate the world. Second, they serve as signals to manipulate others. Philosophers and psychologists have focused on the first function while largely overlooking the second. This article advances a conception of signals and makes a prima facie case for a social signaling function for at least some beliefs. Truth and rational support are often irrelevant to the signaling function. If some beliefs evolved for a signaling function, then we should (...) expect various biases that aid in the manipulation of others. (shrink)

Proposals for regulating or nudging healthy choices are controversial. Opponents often argue that individuals should take responsibility for their own health, rather than be paternalistically manipulated for their own good. In this paper, I argue that people can take responsibility for their own health only if they satisfy certain epistemic conditions, but we live in an epistemic environment in which these conditions are not satisfied. Satisfying the epistemic conditions for taking responsibility, I argue, requires regulation of this environment. I describe (...) some proposals for such regulation and show that we cannot reject all regulation in the name of individual responsibility. We must either regulate individuals’ healthy choices or regulate the epistemic environment. (shrink)

Antisemitism is fun. This essay explains why and proposes a new approach to combating it.

We are all apt to alter our beliefs and even our principles to suit the prevailing winds. Examples abound in public life, but we are all subject to similar reversals. We often accuse one another of hypocrisy when these kinds of reversals occur. Sometimes the accusation is justified. In this paper, however, I will argue that in many such cases, we don’t manifest hypocrisy, even if our change of mind is not in response to new evidence. Marshalling evidence from psychology (...) and evolutionary theory, I will suggest that we are designed to update our beliefs in response to social signals: as these signals change, we change our minds, often without even noticing.

ABSTRACT An intellectually charitable understanding of populism might begin by recognizing that, since populist citizens tend to be politically uninformed and lacking in higher education, populist ideas are likely to be inarticulate reproductions of the tacit assumptions undergirding non-populist or “mainstream” culture rather than stemming from explicit theoretical constructs, such as an apotheosis of the unity or the will of “the people.” What features of our ambient culture, then, could explain the simplistic and combative approach that populists seem to take (...) to politics and policy, their impatience with political debate and deliberation, their willingness to set aside democratic legal forms and political norms, their nationalism, their personalization of politics, their inclination toward conspiracy theorizing, their fondness for fringe sources of information, and their suspicion of political, scientific, and media elites? Using focus group and survey data, we can understand these populist traits as reflections of the culture of “democratic technocracy”: a regime in which we, the people, are assumed capable of rendering sound judgments about how to solve our social and economic problems. Whether or not this assumption is warranted, its cultural dominance seems likely to generate the ideas that populist citizens apparently take for granted. (shrink)

Populism, as I shall understand the term here, is a style of political rhetoric that posits a Manichean conflict between the people and corrupt elites. In the present decade, populism has played a particularly salient role in the politics of the United States and Europe. Moreover, populism is commonly associated with a kind of skepticism about expertise, on which the opinions of non- experts are to be preferred to any expert consensus. In light of all this, populist expertise skepticism appears (...) to be a kind of pathology of excessive intellectual autonomy. I shall argue, however, that this connection between populism and intellectual autonomy is mere appearance: populist expertise skepticism does not involve excessive intellectual autonomy, because it does not involve a disposition for non-deferential belief, but rather a disposition for deference to “alternative” sources of information.
