The paper argues for the centrality of believing the speaker (as distinct from believing the statement) in the epistemology of testimony, and develops a line of thought from Angus Ross which claims that in telling someone something, the kind of reason for belief that a speaker presents is of an essentially different kind from ordinary evidence. Investigating the nature of the audience's dependence on the speaker's free assurance leads to a discussion of Grice's formulation of non-natural meaning in an epistemological (...) light, concentrating on just how the recognition of the speaker's self-reflexive intention is supposed to count for his audience as a reason to believe P. This is understood as the speaker's explicitly assuming responsibility for the truth of his statement, and thereby constituting his utterance as a reason to believe. (shrink)

The relationship between knowledge, belief, and ethics is an inaugural theme in philosophy; more recently, under the title “ethics of belief” philosophers have worked to develop the appropriate methodology for studying the nexus of epistemology, ethics, and psychology. The title “ethics of belief” comes from a 19th-century paper written by British philosopher and mathematician W.K. Clifford. Clifford argues that we are morally responsible for our beliefs because each belief that we form creates the cognitive circumstances for related beliefs to follow, (...) and we inevitably influence each other through those beliefs. This study argues that recent cognitive research supports Cliffordian insights regarding patterns of belief formation and social influence. From the confirmation offered by such research, it follows that informational accuracy holds serious ethical significance in public discourse. Although scientific and epistemological matters are not always thought to be linked to normative morality, this study builds on Clifford's initial insights to show their linkage is fundamental to inquiry itself. In turn, Clifford's ethical and epistemic outline can inform a framework grounded in “public reason” under which seemingly opposed science communication strategies are philosophically united. With public discourse on climate change as the key example, empirically informed and grounded strategies for science communication in the public sphere are considered. (shrink)

Trust is difficult to define. Instead of doing so, I propose that the best way to understand the concept is through a genealogical account. I show how a root notion of trust arises out of some basic features of what it is for humans to live socially, in which we rely on others to act cooperatively. I explore how this concept acquires resonances of hope and threat, and how we analogically apply this in related but different contexts. The genealogical account (...) explains both why the notion has such value for us and why it is difficult to define. (shrink)

In this paper I argue for a special kind of injustice I call “trust injustice.” Taking Miranda Fricker's work on epistemic injustice as my starting point, I argue that there are some ethical constraints on trust relationships. If I am right about this, then we sometimes have duties to maintain trust relationships that are independent of the social roles we play.

Science strives for coherence. For example, the findings from climate science form a highly coherent body of knowledge that is supported by many independent lines of evidence: greenhouse gas emissions from human economic activities are causing the global climate to warm and unless GHG emissions are drastically reduced in the near future, the risks from climate change will continue to grow and major adverse consequences will become unavoidable. People who oppose this scientific body of knowledge because the implications of cutting (...) GHG emissions—such as regulation or increased taxation—threaten their worldview or livelihood cannot provide an alternative view that is coherent by the standards of conventional scientific thinking. Instead, we suggest that people who reject the fact that the Earth’s climate is changing due to greenhouse gas emissions oppose whatever inconvenient finding they are confronting in piece-meal fashion, rather than systematically, and without considering the implications of this rejection to the rest of the relevant scientific theory and findings. Hence, claims that the globe “is cooling” can coexist with claims that the “observed warming is natural” and that “the human influence does not matter because warming is good for us.” Coherence between these mutually contradictory opinions can only be achieved at a highly abstract level, namely that “something must be wrong” with the scientific evidence in order to justify a political position against climate change mitigation. This high-level coherence accompanied by contradictory subordinate propositions is a known attribute of conspiracist ideation, and conspiracism may be implicated when people reject well-established scientific propositions.

There is a widely accepted family of views in the epistemology of testimony centering around the claim that belief is the central item involved in a testimonial exchange. For instance, in describing the process of learning via testimony, Elizabeth Fricker provides the following: “one language-user has a belief, which gives rise to an utterance by him; as a result of observing this utterance another user of the same language, his audience, comes to share that belief.” In a similar spirit, Alvin (...) Plantinga says that “…a belief on the part of the testifiee has warrant only if that belief has warrant for the testifier.” In both of these passages, we find strands of what I shall call the Belief View of Testimony.

Can we decide to trust? Sometimes, yes. And when we do, we need not believe that our trust will be vindicated. This paper is motivated by the need to incorporate these facts into an account of trust. Trust involves reliance; and in addition it requires the taking of a reactive attitude to that reliance. I explain how the states involved here differ from belief. And I explore the limits of our ability to trust. I then turn to the idea of (...) trusting what others say. I suggest that we sometimes decide to trust people to be sincere and knowledgeable; and that having taken this attitude towards them, we come to believe what they say. I spell out some consequences that this has for an account of testimony, and for van Fraassen's decision theoretic principle of Reflection. (shrink)

Beyond philosophy, discussions of trust and trustworthiness often concern collective entities such as corporations, states, and social groups. But much philosophical work takes trust in an individual person as paradigmatic, distinguishing such trust from mere reliance. This chapter explores the distinction between trustworthiness and mere reliability as it applies to collectives, arguing that the distinction does not have the same significance as it has in the individual case.

Fricker shows that virtue epistemology provides a general epistemological idiom in which these issues can be forcefully discussed.

Miranda Fricker's book Epistemic Injustice is an original and stimulating contribution to contemporary epistemology. Fricker's main aim is to illustrate the ethical aspects of two of our basic epistemic practices, namely conveying knowledge to others and making sense of our own social experiences. In particular, she wishes to investigate the idea that there are prevalent and distinctively epistemic forms of injustice related to these aspects of our epistemic lives, injustices which reflect the fact that our actual epistemic practices are socially (...) situated. Most of the book focuses on two such forms – Testimonial Injustice and Hermeneutical Injustice – and on the epistemic virtues required to counteract them.Testimonial Injustice occurs when a hearer fails, because of prejudice, to give due credit to the word of a speaker. For instance, in the novel To Kill a Mockingbird, the jury in the trial of Tom Robinson fail to regard his testimony as credible because he …. (shrink)

A key debate in the epistemology of testimony concerns when it is reasonable to acquire belief through accepting what a speaker says. This debate has been largely understood as the debate over how much, or little, assessment and monitoring an audience must engage in. When it is understood in this way the debate simply ignores the relationship speaker and audience can have. Interlocutors rarely adopt the detached approach to communication implied by talk of assessment and monitoring. Audiences trust speakers to (...) be truthful and demonstrate certain reactive attitudes if they are not. Trust and the accompanying willingness to these reactive attitudes can then provide speakers with a reason to be trustworthy. So through ignoring interlocutors' engagement with the communicative process, the existing debate misses the possibility that it is an audience's trusting a speaker that makes it reasonable for the audience to accept what the speaker says.

In trusting a speaker we adopt a credulous attitude, and this attitude is basic: it cannot be reduced to the belief that the speaker is trustworthy or reliable. However, like this belief, the attitude of trust provides a reason for accepting what a speaker says. Similarly, this reason can be good or bad; it is likewise epistemically evaluable. This paper aims to present these claims and offer a genealogical justification of them.

Belief polarization is said to occur when two people respond to the same evidence by updating their beliefs in opposite directions. This response is considered to be “irrational” because it involves contrary updating, a form of belief updating that appears to violate normatively optimal responding, as for example dictated by Bayes' theorem. In light of much evidence that people are capable of normatively optimal behavior, belief polarization presents a puzzling exception. We show that Bayesian networks, or Bayes nets, can simulate (...) rational belief updating. When fit to experimental data, Bayes nets can help identify the factors that contribute to polarization. We present a study into belief updating concerning the reality of climate change in response to information about the scientific consensus on anthropogenic global warming. The study used representative samples of Australian and U.S. participants. Among Australians, consensus information partially neutralized the influence of worldview, with free-market supporters showing a greater increase in acceptance of human-caused global warming relative to free-market opponents. In contrast, while consensus information overall had a positive effect on perceived consensus among U.S. participants, there was a reduction in perceived consensus and acceptance of human-caused global warming for strong supporters of unregulated free markets. Fitting a Bayes net model to the data indicated that under a Bayesian framework, free-market support is a significant driver of beliefs about climate change and trust in climate scientists. Further, active distrust of climate scientists among a small number of U.S. conservatives drives contrary updating in response to consensus information among this particular group. (shrink)

In this book Zagzebski gives an extended argument that the self-reflective person is committed to belief on authority. Epistemic authority is compatible with autonomy, but epistemic self-reliance is incoherent. She argues that epistemic and emotional self-trust are rational and inescapable, that consistent self-trust commits us to trust in others, and that among those we are committed to trusting are some whom we ought to treat as epistemic authorities, modeled on the well-known principles of authority of Joseph Raz. These principles apply (...) to authority in the moral and religious domains. (shrink)

Paul Faulkner presents a new theory of testimony - the basis of much of what we know. He addresses the questions of what makes it reasonable to accept a piece of testimony, and what warrants belief formed on that basis. He rejects rival theories and argues that testimonial knowledge and testimonially warranted belief are based on trust.

Most traditional epistemologists see trust and knowledge as deeply antithetical: we cannot know by trusting in the opinions of others; knowledge must be based on evidence, not mere trust. I argue that this is badly mistaken. Modern knowers cannot be independent and self-reliant. In most disciplines, those who do not trust cannot know. Trust is thus often more epistemically basic than empirical evidence or logical argument, for the evidence and the argument are available only through trust. Finally, since the reliability (...) of testimonial evidence depends on the trustworthiness of the testifier, this implies that knowledge often rests on a foundation of ethics. The rationality of many of our beliefs depends not only on our own character, but on the character of others. (shrink)

Through communication, we form beliefs about the world, its history, others and ourselves. A vast proportion of these beliefs we count as knowledge. We seem to possess this knowledge only because it has been communicated. If those justifications that depended on communication were outlawed, all that would remain would be body of illsupported prejudice. The recognition of our ineradicable dependence on testimony for much of what we take ourselves to know has suggested to many that an epistemological account of testimony (...) should be essentially similar to accounts of perception and memory. This premise I want to dispute. (shrink)
