Trust is commonly defined as a metaphysically-hybrid notion involving an attitude and an action. The action component of trust is defined as a special form of reliance in which the trustor has: (1) heightened expectations of their trustee; and (2) a disposition to justifiably feel betrayed if their trust is broken. The first aim of this paper is to reject the view that trust is a form of reliance. -/- The second aim of this paper is to develop and defend (...) a non-reliance-based variation of Katherine Hawley’s commitment trust account. Roughly, on my variant account, if X trusts Y to ϕ, then X has a belief with the following counterfactual as its content: ‘if I were to rely on Y to keep a commitment to ϕ, then I believe that Y would keep that commitment to ϕ.’ I defend this account against the objection that non-reliance accounts cannot explain the intuition that trust involves heightened expectations, and that it elicits justified betrayal when broken. I also respond to the argument that such accounts can’t provide adequate explanations of therapeutic trust, which is taken to be a counterexample of belief trust insofar as it describes instances where trustors trust trustees despite not believing that they are trustworthy.

In this paper, I develop and defend a moralized conception of epistemic trust in science against a particular kind of non-moral account defended by John (2015, 2018). I suggest that non-epistemic value considerations, non-epistemic norms of communication and affective trust properly characterize the relationship of epistemic trust between scientific experts and non-experts. I argue that it is through a moralized account of epistemic trust in science that we can make sense of the deep-seated moral undertones that are often at play (...) when non-experts (dis)trust science.

Abstract: There are epistemic manipulators in the world. These people are actively attempting to sacrifice epistemic goods for personal gain. In doing so, manipulators have led many competent epistemic agents into believing contrarian theories that go against well-established knowledge. In this paper, I explore one mechanism by which manipulators get epistemic agents to believe contrarian theories. I do so by looking at a prominent empirical model of trustworthiness. This model identifies three major factors that epistemic agents look for when trying (...) to determine who is trustworthy. These are (i) ability, (ii) benevolence, and (iii) moral integrity. I then show how manipulators can manufacture the illusion that they possess these factors. This leads epistemic agents to view manipulators as trustworthy sources of information. Additionally, I argue that fact-checking will be an ineffective – or even harmful – practice when correcting the beliefs of epistemic agents who have been tricked by this illusion of epistemic trustworthiness. I suggest that in such cases we should use an alternative correction, which I call trust undercutting. (shrink)

Philosophical Psychology is dedicating this issue on trust and trustworthiness to Katherine Hawley (1971–2021) for two reasons. First, she was an expert in the area. Hawley was one of the most rele...

We are frequently confronted with moral situations that are unsettling, confusing, disorienting. We try to come to grips with them. When we do so, we engage in a distinctive type of moral inquiry: hermeneutical inquiry. Its aim is to make sense of our situation. What is it to make sense of one's situation? Hermeneutical inquiry is part of our everyday moral experience. Understanding its nature and its place in moral epistemology is important. Yet, I argue, that existing accounts of moral (...) inquiry do not give us the resources to do so. This paper develops a positive account of hermeneutical inquiry. I argue that when we engage in hermeneutical inquiry, we search for an apt perspective on our situation. (shrink)

I argue that faith is a type of trust. It is also part of a relationship in which both parties are called on to be faithful, where faithfulness is a type of trustworthiness. What distinguishes faith relationships from trust relationships is that both parties value the faith relationship intrinsically. I discuss how faith on this account can, and cannot, be rational when it goes beyond a person’s evidence. It turns out that faith has the same rationality conditions as trust, differing (...) from it only in the cases that fix our intuitions. (shrink)

Trust and monitoring are traditionally antithetical concepts. Describing trust as a property of a relationship of reliance, we introduce a theory of trust and monitoring, which uses mathematical models based on two classes of functions, including _q_-exponentials, and relates the levels of trust to the costs of monitoring. As opposed to several accounts of trust that attempt to identify the special ingredient of reliance and trust relationships, our theory characterizes trust as a quantitative property of certain relations of reliance that (...) can be quantified and expressed as a scalar quantity. Our theory is applicable to both human–human and human–artificial agent interactions, as it is agnostic with respect to the concrete realization of trustworthiness properties, and is compatible with many views differing on which properties contribute to trust and trustworthiness. Finally, as our mathematical models make the quantitative features of trust measurable, they provide empirical studies on trust with a rigorous methodology for its measurement. (shrink)

The aim of this paper is to better qualify the problem of online trust. The problem of online trust is that of evaluating whether online environments have the proper design to enable trust. This paper tries to better qualify this problem by showing that there is no unique answer, but only conditional considerations that depend on the conception of trust assumed and the features that are included in the environments themselves. In fact, the major issue concerning traditional debates surrounding online (...) trust is that those debates focus on specific definitions of trust and specific online environments. Ordinarily, a definition of trust is assumed and then environmental conditions necessary for trust are evaluated with respect to such specific definition. However, this _modus operandi_ fails to appreciate that trust is a rich concept, with a multitude of meanings and that there is still no strict consensus on which meaning shall be taken as the proper one. Moreover, the fact that online environments are constantly evolving and that new design features might be implemented in them is completely ignored. In this paper, the richness of the philosophical discussions about trust is brought into the analysis of online trust. I first provide a set of conditions that depend on the definition of trust that can be assumed and then discuss those conditions with respect to the design of online environments in order to determine whether they can enable (and under which circumstances) trust.

Trust is critical for social life, and yet it is alarmingly fragile. It is easily damaged and difficult to repair. Philosophers studying trust have often noted that basic kind of trust needs to be in place in order for social life to be possible. Although philosophers have suggested that basic trust must exist, they have not tried to describe in explicit terms what this basic trust looks like, or how it comes to be. In this article I will identify and (...) describe a basic form of trust that I call recognition trust. It is a latent expectation we have in others to respect our moral status as persons. By conceptualizing recognition trust, I can explain why trust is not just a useful tool for social cooperation: having our personhood recognized is necessary for living a minimally decent human life, and trust is a necessary element of recognition. First, I motivate the need for conceptualizing a basic form of trust by looking at cases of moral injury and our inherent vulnerability. Such injuries involve the betrayal of an expectation we have in others to recognize us as persons with moral status. Second, I dig deeper into this basic human need of recognition that is thwarted in moral injuries. I argue that fulfilling this basic need requires a particular kind of trust that others will not morally injure us. Third, I give shape to recognition trust by describing its core features, showing why it is a candidate for basic trust. Finally, I defend my concept of recognition trust against a pair of objections. (shrink)

Where there is trust, there is also vulnerability, and vulnerability can be exploited. Epistemic trust is no exception. This chapter maps the phenomenon of the exploitation of epistemic trust. I start with a discussion of how trust in general can be exploited; a key observation is that trust incurs vulnerabilities not just for the party doing the trusting, but also for the trustee (after all, trust can be burdensome), so either party can exploit the other. I apply these considerations to (...) epistemic trust, specifically in testimonial relationships. There, we standardly think of a hearer trusting a speaker. But we miss an important aspect of this relationship unless we consider too that the speaker standardly trusts the hearer. Given this mutual trust, and given that both trustees and trusters can exploit each other, we have four possibilities for exploitation in epistemic-trust relationships: a speaker exploiting a hearer (a) by accepting his trust or (b) by imposing her trust on him, and a hearer exploiting a speaker (c) by accepting her trust or (d) by imposing his trust on her. One result is that you do not need to betray someone to exploit him – you can exploit him just as easily by doing what he trusts you for. (shrink)

Trust should be able to explain cooperation, and its failure should help explain the emergence of cooperation-enabling institutions. This proposed methodological constraint on theorizing about trust, when satisfied, can then be used to differentiate theories of trust with some being able to explain cooperation more generally and effectively than others. Unrestricted views of trust, which take trust to be no more than the disposition to rely on others, fare well compared to restrictive views, which require the trusting person to have (...) some further attitude in addition to this disposition. The same methodological constraint also favours some restrictive views over others. (shrink)

This paper treats two questions about the relation between trust and the will. One question, about trust, is whether you can trust ‘at will.’ Can you trust despite acknowledging that you lack evidence of the trustee’s worthiness of your trust? Another question, about the will, is whether you can exercise your will at all without trust – at least, in yourself. I treat the second question as a guide to the first, arguing that the role of trust in the will (...) reveals how you can trust at will. The key lies in distinguishing two ways of being responsive to evidence. On the one hand, you cannot trust someone – whether another person or your own earlier self – whom you judge unworthy of your trust. On the other hand, trust does not require a positive assessment of trustworthiness. I thus take issue with Pamela Hieronymi’s analysis of trust as a “commitment-constituted attitude.” Your trust is indeed constrained by your responsiveness to evidence of untrustworthiness, but you need undertake no commitment akin to or involving a judgment that the trustee is trustworthy. We can see why trust is not a commitment-constituted attitude by seeing how trust itself plays a role in forming a commitment. (shrink)

In this paper we raise the question whether technological artifacts can properly speaking be trusted or said to be trustworthy. First, we set out some prevalent accounts of trust and trustworthiness and explain how they compare with the engineer’s notion of reliability. We distinguish between pure rational-choice accounts of trust, which do not differ in principle from mere judgments of reliability, and what we call “motivation-attributing” accounts of trust, which attribute specific motivations to trustworthy entities. Then we consider some examples (...) of technological entities that are, at first glance, best suited to serve as the objects of trust: intelligent systems that interact with users, and complex socio-technical systems. We conclude that the motivation-attributing concept of trustworthiness cannot be straightforwardly applied to these entities. Any applicable notion of trustworthy technology would have to depart significantly from the full-blown notion of trustworthiness associated with interpersonal trust. (shrink)

In this dissertation I defend five claims about trust: 1) trusting and trustworthiness are conceptually but not causally connected; 2) trust is risky; 3) trust requires good will; 4) trust is a two-part relation; and 5) trust is an interpretative framework. A concern for trust often appears in discussions about testimony and the expectation of truthfulness; Bentley Glass, John Hardwig, and Jonathan Adler each address the role of trust in science while assuming a necessary connection between trusting and trustworthiness. I (...) argue that this conception is untenable because a justification for one fails to suffice as a justification of the other. I show, instead, that it is our assessment that links trustworthiness to trusting. My second claim, that trust involves risk, is contentious. I argue that the common understanding of risk as harm, which is held by Russell Hardin, contains the more technical understanding of risk as uncertainty, which is suggested by Niklas Luhman. Trust is risky precisely because it is inherently uncertain. Annette Baier argues that failing to recognize a distinction between trusting and action associated with that trust leads us to accept accounts of trust that are too broad. I argue that trust is to believe that another is concerned with your well-being, has good will, because she is concerned about you and not that it will necessarily benefit her in some way. Seeing trust as good will allows me to advance my fourth claim, that trust is a two-part relation, because trust is the assessment of another's good will towards me. Trusting another is believing that the other's good judgment will include concern and consideration for my interests because they are my interests. My fifth point follows naturally once trust is understood to be a risky, two-part relation requiring good will: it is an interpretive framework. Our trust in another sets the tone for understanding her behavior such that we take her actions as either supporting or blocking our interests. This account takes the capacity to trust to be the foundation for, rather than merely an outgrowth of, our judgments. (shrink)

Some recent accounts of testimonial warrant base it on trust, and claim that doing so helps explain asymmetries between the intended recipient of testimony and other non-intended hearers, e.g. differences in their entitlement to challenge the speaker or to rebuke the speaker for lying. In this explanation ‘dependence-responsiveness’ is invoked as an essential feature of trust: the trustor believes the trustee to be motivationally responsive to the fact that the trustor is relying on the trustee. I argue that dependence-responsiveness is (...) not essential to trust and that the asymmetries, where genuine, can be better explained without reference to trust. (shrink)

A summary of the philosophical literature on trust.

A lot of what we understand to be trust is not trust; it is, instead, an active and conscious decision to feign trust. We call this ‘as-if’ trust. If trust involves taking on risks and vulnerabilities, as-if trust involves taking on surplus risks and vulnerabilities. People may decide to act as if they trust in many situations, even when they do not have sufficient warrant to trust – which is to say even when they do not trust. Likewise, people might (...) decide to act as if they trust even when they have good reasons to actively distrust. The surplus risks of as-if trust may be worth taking in a number of different contexts and for many reasons. We argue that as-if trust is a concept that should be added to our theoretical, practical, and political vocabularies of trust and distrust. In doing so, we discuss the main reasons for someone to act as if they trust. We then show that the practice of as-if trust has been recognized by other scholars but treated as trust. In response, we clarify how as-if trust differs from trust, and we discuss the utility and ubiquity of as-if trust, especially in politics. (shrink)

With focus on the development and use of artificial intelligence (AI) systems in the digital health context, we consider the following questions: How does the European Union (EU) seek to facilitate the development and uptake of trustworthy AI systems through the AI Act? What does trustworthiness and trust mean in the AI Act, and how are they linked to some of the ongoing discussions of these terms in bioethics, law, and philosophy? What are the normative components of trustworthiness? And how (...) do the requirements of the AI Act relate to these components? We first explain how the EU seeks to create an epistemic environment of trust through the AI Act to facilitate the development and uptake of trustworthy AI systems. The legislation establishes a governance regime that operates as a socio-epistemological infrastructure of trust which enables a performative framing of trust and trustworthiness. The degree of success that performative acts of trust and trustworthiness have achieved in realising the legislative goals may then be assessed in terms of statutorily defined proxies of trustworthiness. We show that to be trustworthy, these performative acts should be consistent with the ethical principles endorsed by the legislation; these principles are also manifested in at least four key features of the governance regime. However, specified proxies of trustworthiness are not expected to be adequate for applications of AI systems within a regulatory sandbox or in real-world testing. We explain why different proxies of trustworthiness for these applications may be regarded as ‘special’ trust domains and why the nature of trust should be understood as participatory. (shrink)

A lot of attention has recently been devoted to the notion of Trustworthy AI (TAI). However, the very applicability of the notions of trust and trustworthiness to AI systems has been called into question. A purely epistemic account of trust can hardly ground the distinction between trustworthy and merely reliable AI, while it has been argued that insisting on the importance of the trustee’s motivations and goodwill makes the notion of TAI a categorical error. After providing an overview of the (...) debate, we contend that the prevailing views on trust and AI fail to account for the ethically relevant and value-laden aspects of the design and use of AI systems, and we propose an understanding of the notion of TAI that explicitly aims at capturing these aspects. The problems involved in applying trust and trustworthiness to AI systems are overcome by keeping apart trust in AI systems and interpersonal trust. These notions share a conceptual core but should be treated as distinct ones. (shrink)

Much bioethical literature and policy guidances for big data analytics in biomedical research emphasize the importance of trust. It is essential that potential participants trust so they will allow their data to be used to further research. However, comparatively, little guidance is offered as to what trustworthy oversight mechanisms are, or how policy should support them, as data are collected, shared, and used. Generally, “trust” is not characterized well enough, or meaningfully enough, for the term to be systematically applied in (...) policy development. Yet points made in the philosophical literature on trust can help. They allow us, not only to better distinguish the different ways the term “trust” may be interpreted, but also to better determine how different approaches to trust can align with policy and governance—in what ways they may relate to key bioethical concepts and related laws, and in what ways they can help to balance individual and group interests in data sharing. This article draws from the philosophical literature on trust to identify a relationship among consent, trust, and justice. Specifically, parallels are drawn between “character-trustworthiness” and “natural justice,” a set of widely held legal safeguards intended to ensure decision-makers follow a pattern of procedural fairness which protects the rights of the individual and thereby maintains public confidence in the decision-making process. Relevance to traditional bioethical principles, established laws, and consent procedures are addressed throughout. In conclusion, policy actions are suggested. (shrink)

Trust is often perceived as having great value. For example, there is a strong belief that trust will bring different sorts of public goods and help us preserve common resources. A related concept which is just as important, but perhaps not explicitly discussed to the same extent as “trust”, is “reliance” or “confidence”. To be able to rely on some agent is often seen as a prerequisite for being able to trust this agent. Up to now, the conceptual discussion about (...) the definition of trust and reliance has been rational in the sense that most people involved have offered arguments for their respective views, or against competing views. While these arguments rely on some criterion or other, these criteria are rarely explicitly stated, and to our knowledge, no systematic account of such criteria has been offered. In this paper we give an account of what criteria we should use to assess tentative definitions of “trust” and “reliance”. We will also offer our own well-founded definitions of “trust” and “reliance”. Trust should be regarded as a kind of reliance and we defend what we call “the accountability view” of trust, by appealing to the desiderata we identify in the first parts of the paper. (shrink)

I outline a number of parallels between trust and distrust, emphasising the significance of situations in which both trust and distrust would be an imposition upon the (dis)trustee. I develop an account of both trust and distrust in terms of commitment, and argue that this enables us to understand the nature of trustworthiness. Note that this article is available open access on the journal website.

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)

Across the management, social science, and business ethics literatures, and in much of the philosophy literature, trust is characterized as a disposition to act given epistemic states—beliefs and/or expectations about others and about the risks involved. This characterization of trust is best thought of as epistemological because epistemic states distinguish trust from other dispositions. The epistemological characterization of trust is the amoral one referred to in the title of this paper, and we argue that this characterization is conceptually inadequate. We (...) outline and defend an alternative conception of trust as a moral phenomenon: when A trusts B to do something, A invites B to acknowledge and accept an obligation; when B accepts the invitation, B takes on an obligation; in that way trust creates an obligation. We conclude with an application, drawing out the difference between the epistemological conception of trust and our own in the context of Ghoshal et al.'s (Sloan Management Review 40:9—20, 1995, Academy of Management Learning & Education 4:75—91, 2005) critique of transaction cost theories of the firm.

Should we be worried that the concept of trust is increasingly used when we assess non-human agents and artefacts, say robots and AI systems? Whilst some authors have developed explanations of the concept of trust with a view to accounting for trust in AI systems and other non-agents, others have rejected the idea that we should extend trust in this way. The article advances this debate by bringing insights from conceptual engineering to bear on this issue. After setting up a (...) target concept of trust in terms of four functional desiderata (trust-reliance distinction, explanatory strength, tracking affective responses, and accounting for distrust), I analyze how agential vs. non-agential accounts can satisfy these. A final section investigates how ‘non-ideal’ circumstances—that is, circumstances where the manifest and operative concept use diverge amongst concept users—affect our choice about which rendering of trust is to be preferred. I suggest that some prominent arguments against extending the language of trust to non-agents are not decisive and reflect on an important oversight in the current debate, namely a failure to address how narrower, agent-centred accounts curtail our ability to distrust non-agents.

Establishing trust among individual agents has defined a central issue of practical reasoning since the dawning of liberal individualism. Hobbes was convinced that foolish self-interest always threatens to defeat uncompelled cooperation when one can gain by abandoning a joint effort. Against this philosophical background, scientific studies of human beings display a surprisingly cooperative species. It would seem to follow that biologically inherited characteristics impair our reason. The response proposed here distinguishes rationality and reasonableness as two forms of good reasoning. One (...) is consistent with the model of strategic rationality, the other with a model of emotional relationship. From the Hobbesian perspective trusting agents are not rational if their makeup discourages advantageous defection even when one knows it will not be detected or punished. The point is indecisive because reasonable trust insulates cooperative action from the factors that have appeared to make it chancy or unstable without some enforcing power. A critical theme is that trust does not simply rest upon a biological disposition to conform to norms. That would explain but not justify aversion to defection. In fact, trust can survive reasoned challenges to norm-conforming dispositions, displaying the responsible social animal living along with the rational individual. (shrink)

Many recent AI policies have been structured under labels that follow a particular trend: national or international guidelines, policies or regulations, such as the EU’s and USA’s ‘Trustworthy AI’ and China’s and India’s adoption of ‘Responsible AI’, use a label that follows the recipe of [agentially loaded notion + ‘AI’]. A result of this branding, even if implicit, is to encourage the application by laypeople of these agentially loaded notions to the AI technologies themselves. Yet, these notions are appropriate only (...) when applied to agents, which current AI technologies are not; and the concern is that this misapplication creates an incentive to inappropriately attribute trustworthiness or responsibility to AI technologies. We endeavour to show that we have good reason to avoid any general AI policy that uses agentially loaded labelling. We suggest labelling these policies not in terms of some qualification of AI, but rather in terms of our approach to the technology and its wider development and use context – focusing on being trustworthy and responsible about AI, rather than on trustworthy or responsible AI.

This paper proposes freedom as the condition of possibility for the construction of trust in human relationships. The methodology used is a review of the scientific literature of the most recent moral and political philosophy. As a result of the dialogue between different positions, it is discovered that freedom, despite being present in the act of trust, is forgotten in the discussion around trust, a forgetfulness that has as its main causes the assumption that trust is natural and the confusion (...) between the propensity to trust and the act of trusting. All this leads to proposing an approach of the act of trusting that starts from the freedom of the trustee and the trustor. (shrink)

A standard view of trust sees trust as intimately related to reliance; on this standard view, trust is reliance plus some other factor. A significant literature has now developed that seeks to explain what factor, in addition to reliance, serves to distinguish cases of trust from cases of mere reliance. I argue that this approach to the analysis of trust is misguided. Although reliance, properly understood, frequently accompanies trust, reliance is not a necessary condition of trust.

Free riding involves benefiting from common resources or services while avoiding contributing to their production and maintenance. Few studies have adequately investigated the propensity to overestimate the prevalence of free riding. This is a significant omission, as exaggeration of the phenomenon is often used to justify control and coercion systems. To address this gap, we investigate how the common good approach may mitigate the flaws of a system excessively focused on free-riding risk. In this conceptual paper featuring illustrative vignettes, we (...) argue that the common good perspective is realistic and effective in preventing this excessive attention by promoting trust as an unconditional gift and a response to vulnerability. We discuss the common good perspective’s originality over the dominant approaches and propose a set of ethical and managerial recommendations that may be the best protection against this excessive focus and maybe even against free riding itself.

Trust is a kind of risky reliance on another person. Social scientists have offered two basic accounts of trust: predictive expectation accounts and staking (betting) accounts. Predictive expectation accounts identify trust with a judgment that performance is likely. Staking accounts identify trust with a judgment that reliance on the person’s performance is worthwhile. I argue (1) that these two views of trust are different, (2) that the staking account is preferable to the predictive expectation account on grounds of intuitive adequacy (...) and coherence with plausible explanations of action; and (3) that there are counterexamples to both accounts. I then set forward an additional necessary condition on trust, according to which trust implies a moral expectation. The content of the moral expectation is this: W hen A trusts B to do x, A ascribes an obligation to B to do x, and holds B to this obligation. This moral expectation account throws new light on some of the consequences of misplaced trust. I use the example of physicians’ defensive behavior to illustrate this final point. (shrink)

What is trust? How does it function as a primary virtue for persuasive arguments? How does its presumption contribute to the effectiveness of an argument’s persuasiveness? This presentation will explore these questions and the controversy among scholars regarding how trust is generated and under what conditions it is lost. We will also discuss whether inauthentic trustworthiness is a manipulation used for gaining a fallacious advantage in argumentation.
