Evaluating the trustworthiness of sources is important in today’s society. However, research has shown that students struggle when applying this skill. This study in history education aims to gain insight into students’ procedural knowledge about evaluating the trustworthiness of sources and into the value students attach to learning this skill. Grade 9 students (N = 132) performed tasks and filled out a questionnaire. Students applied more correct criteria of trustworthiness than they reported knowing. They considered this skill (...) somewhat important and useful, but less interesting. Procedural knowledge and task value were significant predictors of students’ task performance. Therefore, it is important to make students aware of the knowledge they implicitly possess and to make learning this skill more interesting for students. (shrink)

Although trustworthiness has been described as a source of competitive advantage, its value extends to organizational governance and wealth creation. We identify the importance of the commitment—compliance continuum in the decision to trust and note that trustworthiness is a subjective perception viewed through each person's mediating lens. That lens and each person's interpretation of the social contract impact one's commitment to cooperate. We suggest five propositions that integrate trustworthiness, governance, and wealth creation.

Overconfidence is typically damaging to one’s reputation as a trustworthy source of information. Previous research shows that the reputational cost associated with conveying a piece of false information is higher for confident than unconfident speakers. When judging speaker trustworthiness, individuals do not exclusively rely on past accuracy but consider the extent to which speakers expressed a degree of confidence that matched the accuracy of their claims (their “confidence-accuracy calibration”). The present study experimentally examines the interplay between confidence, accuracy (...) and a third factor, namely evidence, in the assessment of speaker trustworthiness. Experiment 1 probes the hypothesis that overconfidence does not backfire when a confident but inaccurate claim is justified: the trustworthiness of a confident speaker who turns out to be wrong is restored if the confidence expressed is based on strong evidence (good confidence-evidence calibration). Experiment 2 investigates the hypothesis that confidence can backfire if a confident and accurate claim is not justified: the trustworthiness of a confident speaker who turns out to be right is damaged if the confidence expressed is based on weak evidence (bad confidence-evidence calibration). Our results support both hypotheses and thus suggest that “confidence-evidence calibration” plays a crucial role in the assessment of speaker trustworthiness. (shrink)

Simion and Kelp defend a non-anthropocentric account of trustworthy AI, based on the idea that the obligations of AI systems should be sourced in purely functional norms. In this commentary, I highlight some pressing counterexamples to their account, involving AI systems that reliably fulfil their functions but are untrustworthy because those functions are antagonistic to the interests of the trustor. Instead, I outline an alternative account, based on the idea that AI systems should not be considered primarily as tools but (...) as technological participants in social practices. Specifically, I propose to source the obligations of an AI system in the norms that should govern the role it plays within the social practices it participates in, taking into account any changes to the social practices that its participation may bring about. This proposal is anthropocentric insofar as it ascribes obligations to AI systems that are similar to those of human participants in social practices, but only modestly so, as it does not require trustworthy AI to have contentious anthropomorphic capacities (e.g. for consciousness or moral responsibility).

There are many instruments of knowledge. The primary feature of an instrument of knowledge is that it be a trustworthy source of information about the world. But what is the source of the trustworthiness of instruments? What does it mean to say that an instrument is a trustworthy source of information that p? Is there, for example, an implicit reference to the trustworthiness of a person who receives the information that p? If the answer to (...) this question is affirmative, then we should modify our first question to include the reference to a subject. Must we then allow that an instrument that is a trustworthy source of information that p for one person is not a trustworthy source of information that p for another? It seems that we must, for one person who understands an instrument may learn an important fact from it when another, who does not, learns nothing at all. But that consideration does not appear to reflect on the trustworthiness of the instrument but, rather, on the trustworthiness of the person who uses it. There are deep and more subtle questions pertaining to knowledge. A person who understands the instrument and a person who does not may both read the instrument and receive correct information that p from it, that is, they may both believe the information that p they receive, but only the person who understands the instrument knows that the information that p is correct. But how can a person receive correct information that p from a trustworthy instrument and not know that p? These are questions I shall attempt to answer. To answer them, we need some account of knowledge, and I proceed briefly with the necessary analysis. (shrink)

This mixed-methods study explores how high school students ( n=35) enrolled in a school with a high Latino/a population evaluate the trustworthiness of documents in two historical reasoning tasks: one about the Dust Bowl in the 1930s and the other about the experiences of Mexicans and Mexican Americans in the 1920s. Students indicated whether they trusted each document, provided a rationale for their trust (or distrust) of each document, and ranked the trustworthiness of the documents. We also interviewed (...) 10 focal students to explore students’ reasoning in more in-depth ways than the written responses allowed. We found that students tended to trust the secondary source documents more than the primary source documents because, as they argued, the secondary source documents contained more facts. In contrast, students were less likely to trust the primary source documents, particularly the songs, arguing that they were more opinion-based than factual. We also found that some students had an emotional response to the content of some of the documents, and in some cases, these emotional responses shaped how they viewed the documents’ trustworthiness. Additionally, students’ heritage may have played a role in some students’ trust justifications for some documents in the experiences of Mexicans and Mexican Americans task. We conclude with implications for curriculum and instruction. (shrink)

The face is a powerful source to make inferences about one’s trustworthiness. Recent studies demonstrated that facial trustworthiness is influenced by the level of threat conveyed by the visual scene in which faces are embedded: untrustworthy-looking faces are more likely judged as untrustworthy when shown in threatening scenes. Here, we explore whether this face-context congruency effect is specific to the negative pole of the threat-trust domain. Experiment 1 (N = 89) focused on the differential impact of positive (...) vs. negative face-context congruency within the domains of threat and trust. Negative congruency (i.e. untrustworthy-looking faces in threatening contexts) led to more extreme attributions as opposed to positive congruency (i.e. trustworthy-looking faces in reassuring contexts). Experiment 2 (N = 120) replicated these findings by further showing their domain-specificity. The negativity bias was found in the threat-trust domain, but not when extroverted- vs. introverted-looking faces appeared in happy vs. sad context scenes. Experiment 3 (N = 154, pre-registered) replicated the pattern observed in Experiment 1 while controlling for the extent to which both threatening and reassuring context stimuli were related to the human action. We discussed the theoretical implications of these results for understanding how contextual information is integrated into the evaluation of facial trustworthiness. (shrink)

Bearing witness is a familiar if diversely employed concept. On the one hand, it concerns the accuracy and validity of practical affairs, for example in a court of law, at a wedding, or in a law office. On the other hand, the term can embody powerful religious, social, and/ or moral meaning, whether in bearing witness to historical trauma and human suffering, or in paying heed to everyday, seemingly ordinary aspects of nature and of human life. In this article, we (...) address the question of what renders a witness trustworthy. We characterize ethical and epistemic constituents of witnessing. We examine the work of several exemplary witnesses: W. G. Sebald, Saidiya Hartman, Jonathan Lear, Etty Hillesum, and John Berger alongside Jean Mohr. These sources help us think about the education of a person who aspires to bear witness, whether it be to traumatic events or to quotidian life in educational or other settings. We present criteria of trustworthiness that can support reflection on what we take to be the important place of bearing witness in educational inquiry and practice. (shrink)

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)

People increasingly access news through ‘new’, algorithmic intermediaries such as search engines or aggregators rather than the ‘old’ (i. e., traditional), journalistic intermediaries. As algorithmic intermediaries do not adhere to journalistic standards, their trustworthiness comes into question. With this study, we (1) summarize the differences between journalistic and algorithmic intermediaries as found in previous literature; (2) conduct a cross-media comparison of information credibility and intermediary trustworthiness; and (3) examine how key predictors (such as modality, reputation, source attribution, (...) and prior experience) affect the trustworthiness and credibility assessments. Results from a quasi-experimental online survey (n = 485) confirm that recipients assess journalistic intermediaries more positively than algorithmic intermediaries and audio more positively than text intermediaries. Furthermore, we found reputation and information credibility to be the most important predictors of intermediary trustworthiness, while general media trust is the most important predictor of information credibility. Implications and directions for future research are discussed. (shrink)

In this paper, I examine the ethics of e - trust and e - trustworthiness in the context of health care, looking at direct computer-patient interfaces (DCPIs), information systems that provide medical information, diagnosis, advice, consenting and/or treatment directly to patients without clinicians as intermediaries. Designers, manufacturers and deployers of such systems have an ethical obligation to provide evidence of their trustworthiness to users. My argument for this claim is based on evidentialism about trust and trustworthiness: the (...) idea that trust should be based on sound evidence of trustworthiness. Evidence of trustworthiness is a broader notion than one might suppose, including not just information about the risks and performance of the system, but also interactional and context-based information. I suggest some sources of evidence in this broader sense that make it plausible that designers, manufacturers and deployers of DCPIs can provide evidence to users that is cognitively simple, easy to communicate, yet rationally connected with actual trustworthiness.

Open-source communities that focus on content rely squarely on the contributions of invisible strangers in cyberspace. How do such communities handle the problem of trusting that strangers have good intentions and adequate competence? This question is explored in relation to communities in which such trust is a vital issue: peer production of software (FreeBSD and Mozilla in particular) and encyclopaedia entries (Wikipedia in particular). In the context of open-source software, it is argued that trust was inferred from an (...) underlying ‘hacker ethic’, which already existed. The Wikipedian project, by contrast, had to create an appropriate ethic along the way. In the interim, the assumption simply had to be that potential contributors were trustworthy; they were granted ‘substantial trust’. Subsequently, projects from both communities introduced rules and regulations which partly substituted for the need to perceive contributors as trustworthy. They faced a design choice in the continuum between a high-discretion design (granting a large amount of trust to contributors) and a low-discretion design (leaving only a small amount of trust to contributors). It is found that open-source designs for software and encyclopaedias are likely to converge in the future towards a mid-level of discretion. In such a design the anonymous user is no longer invested with unquestioning trust. (shrink)

Open-content communities that focus on co-creation without requirements for entry have to face the issue of institutional trust in contributors. This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software—continue to—rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered (...) instead. Trust (i.e. full write-access) is ‘backgrounded’ by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.

Why do we trust TV news? What reasons might support a recipient’s assessment of the trustworthiness of this kind of information? This paper presents a veritistic analysis of the epistemic practice of news production and communication. The topic is approached by discussing a detailed case study, namely the characteristics of the most popular German news programme, called the ‘Tagesschau’. It will be shown that a veritistic analysis can indeed provide a recipient with relevant reasons to consider when pondering on (...) the trustworthiness of sources of information. Moreover, it will turn out that these reasons are part of what recipients might gather from media literacy. (shrink)

In this paper, we consider the way that web documents seeking to persuade readers of certain science claims provide information about the sources of the arguments. Our quantitative analysis reveals that web documents in our sample include hundreds of examples in which the reader is provided information regarding the trustworthiness of sources. The web documents also contain a large number of examples in which the reader is provided with information about how many individuals hold a particular belief. We discuss (...) ad hominem, ad verecundiam, and ad populum arguments, and the way that the examples found in our sample of documents are related to these argumentation schemes. (shrink)

Aḥmed Cevdet Pasha (d. 1312/1895) is one of the influential and prominent Ottoman scholars in history and law. Besides history and law, he also produced works on literature, sīra (the life of the Prophet) and tafsīr (the Qur’anic exegesis). In the last years of his life, Cevdet Pasha aimed to translate the Qurʾān including short comments on the verses, but this work was remained limited to the sūrah al-Baqara. Correspondingly to this translation named Terjeme-i Sharīfa, he prepared a glossary to (...) the Qurʾān called Lāḥiqa-i Sharīfa for expressions and terms that require detailed explanation. Hereby, this work could only include the sūrah al-Baqara. After Cevdet Pasha’s death, his books passed to his daughter Ms Fāṭima ʿAliyye (d. 1936). The director of the Library of Maʿārif, Nācī Qāsim (d. 1963) gave a deed stipulating that he would take the first part of the Lāḥiqa-i Sharīfa and Terjeme-i Sharīfa from her and return them as they are. Later on, he published only the Muqaddima (introduction) and Lāḥiqa-i Sharīfa in the work named Tercemeli Ḳurʾân-ı Kerîm (İstanbul: 1927). Placing the Muqaddima at the beginning of the book and Lāḥiqa-i Sharīfa at the end misled some people by making them to think that the translation belongs entirely to Cevdet Pasha. Sulayman Tevfīq reprinted these two works together within his translation named el-Beyān fī ʾāyāti’l-Qurʾān in 1928. Terjeme-i Sharīfa has not been published anywhere else. Emine Armağan recently found and published a notepad in which Cevdet Pasha wrote Terjeme-i Sharīfa, mentioned Muqaddima and Lāḥiqa-i Sharīfa. In her book Emine Armağan printed the pages belonging to Cevdet Pasha as thumbnails, but she did not publish them in Latin. In this article, Muḳaddime and Lâḥika-i Şerîfe are Latinized and compared to the Terceme-i Şerîfe. The relevant parts of the translation are given in the footnotes. This study is an attempt to determine to what extent the translation in the manuscript form corresponds to the glossary and the soundness of relating the text to the author. In addition, many errors in the Ottoman edition of the glossary were also corrected. In the Muqaddima, Cevdet Pasha draws attention to the necessity of God’s existence, the illiteracy and the trustworthiness of his Messenger, and that the revelation is the primary source of knowledge for people. He summarizes the process of the Qurʾān’s revelation, notification and compilation. He briefly touches on the issues related to ʿUlūm al-Qurʾān. Cevdet Pasha, who passed from here to the miracle of the Qurʾān, talks about the qadim (pre-existing) nature of the divine word and teḥaddī. Cevdet Pasha emphasizes that understanding the Qurʾān is possible only by knowing the Arabic language very well and whithout this knowldege the Qurʾān cannot adequately be translated into another language. On the other hand, he also believes that the first meanings can be externally translated in order to explain the first meanings of the verses to those who do not know Arabic. Cevdet Pasha’s preface is considerably concise in structure. He shortly pointed to the crucial issues in one sentence and passed to the other subjects. While writing Terjeme-i Sharīfa, Cevdet Pasha left the extensive explanations of the polysemous words and terms that cannot be translated literally to the tafsīr and Lāḥiqa. Cevdet Pasha’s Lāḥiqa-i Sharīfa is entirely original and not merely a translation of any Qurʾānic dictionary. He compiled the meanings of a word existing in different verses, and he was very meticulous in choosing the meanings the words. He summarized very detailed informations in the sources in a simple, concise and fluent style. The arrangement of the words was based on the abbreviated versions used in the Qurʾān. In addition to the lexical meaning of the word, he sometimes mentioned the words’ roots, form, singular and plural forms, ism al-fāʿil, ism al-mefʿūl, ism al-mekān, synonym/antonym, lexical aspects, the meaning and terminology it expresses in different recitations of the Qur’an (al-qırāat). He in particular highlighted if the word is one of the al-asmāʾ al-ḥusnā. He explained the changes in the meaning of a word when it is used for Allah or for humans. He shortly touched on the legal rulings. Cevdet Pasha clearly expressed in his work the most vital issues that the community should know without tiring the general reader of scientific disputes, philosophical discussions and literary analysises. Cevdet Pasha did not refer to any sources in his work and did not mention the transmission chain of the narrations. As a result of our research, we determined that he benefited from the commentaries of al-Zamakhshari (d. 538/1144), al-Rāzī (d. 606/1210), al-Qurṭūbī (d. 671/1273) and Beyḍāvī (d. 685/1286). We have seen that there are some similarities between the explanations of the words in the Lāḥiqa-i Sharīfa and the famous Qurʾānic dictionaries such as al-Mufredāt, Umdet al-ḥuffāẓ and Beṣāir.

What is the nature of children's trust in testimony? Is it based primarily on evidential correlations between statements and facts, as stated by Hume, or does it derive from an interest in the trustworthiness of particular speakers? In this essay, we explore these questions in an effort to understand the developmental course and cognitive bases of children's extensive reliance on testimony. Recent work shows that, from an early age, children monitor the reliability of particular informants, differentiate between those who (...) make true and false claims and keep that differential accuracy in mind when evaluating new information from these people. We argue that this selective trust is likely to involve the mentalistic appraisal of speakers rather than surface generalizations of their behavior. Finally, we review the significance of children's deference to adult authority on issues of naming and categorization. In addition to challenging a purely inductive account of trust, these and other findings reflect a potentially rich set of tools brought by children to the task of learning from people's testimony.

During a dialogue, agents exchange information with each other and need thus to deal with incoming information. For that purpose, they should be able to reason effectively about trustworthiness of information sources. This paper proposes an argument-based system that allows an agent to reason about its own beliefs and information received from other sources. An agent's beliefs are of two kinds: beliefs about the environment and beliefs about trusting sources . Six basic forms of trust are discussed in the (...) paper including the most common one on sincerity. Starting with a base which contains such information, the system builds two types of arguments: arguments in favour of trusting a given source of information and arguments in favour of believing statements which may be received from other agents. We discuss how the different arguments interact and how an agent may decide to trust another source and thus to accept information coming from that source... (shrink)

The Dutch historiography of the middle of the 19thcentury was a culture of honour. Disputes over the reputations of historical figures were manifold. This article focuses on one controversy specifically that took place in the 1840s. The subject of debate was the 16th-century nobleman Henry of Brederode, his deeds, his character and his morals. The controversy was not only about content, however. Many suppositions about doing history and being a historian that otherwise remain tacit, were made explicit in the controversy (...) – especially concerning archive-based history. First, the participating historians themselves were judged – somewhat like Brederode himself – on the virtuousness, including the epistemic virtuousness, of their behaviour. Second, it was discussed whether archival documents were fit for use in historiography. To some, the use of these personal letters was ethically unjustifiable. Third, the location from which historical knowledge originated, mainly the archive, came under scrutiny. The singularity of the archive made historians relying on archival material prone to attacks on their trustworthiness. (shrink)

The recent debate arising from leaked emails from a UK-based research group working on the issue of climate change is another in a long string of historical lapses that periodically threatens public confidence in the institutions and methods of science. As with other similar events, it did not have to happen. What should concern us is that the accepted methods and practices of science have once again to be shown to be too easily set aside, ignored, or broken due to (...) human frailties. Years of research are now in question, publications must be viewed in a new, more skeptical light, and research programs that might have no direct relation with the one involved in the controversy are affected. One response to scandals like “ClimateGate” is to renew an oft-repeated call for increased openness in the sciences. The apparent disappearance or alteration of data, and its implications for the trustworthiness of published results of ongoing research suggests strongly that a more transparent, open, and accessible system could have prevented personal inclinations or policy concerns, even if benevolently motivated, from undermining the indifferent and detached progress of climate science.

Information received from different sources can be inconsistent. Even when the sources of information can be ordered on the basis of their trustworthiness, it turns out that extracting an acceptable notion of support for information is a non-trivial matter, as is the question what information a rational agent should accept. Here it is shown how a support ordering on the information can be generated and how it can be used to decide what information to accept and what not to (...) accept. This ordering, it turns out, is closely related to notions such as Epistemic Entrenchment and Grove spheres studied in belief revision. (shrink)

Large organizations, including listed businesses, financial service providers as well as public services entities are increasingly disclosing information on their environmental, social and governance (ESG) issues through corporate websites or via social media. Therefore, this research uses valid measures from the Elaboration Likelihood Model (ELM) to explore the individuals’ attitudes toward online corporate social responsibility (CSR) communications. The data were gathered from a structured questionnaire among three hundred ninety‐two respondents (n = 392). A structural equations modeling partial least squares (SEM‐PLS (...) 3) approach was used to analyze the data. The findings revealed that the timeliness, relevance and accuracy of information as well as the source expertise were highly significant antecedents that were affecting the research participants’ attitudes toward CSR communications. This contribution implies that there is scope for content curators to publish quality online information on their business activities to improve their trustworthiness and positive credentials among stakeholders.

SummaryThis paper studies some classic cases of the fallacy of begging the question based on appeals to testimony containing circular reasoning. For example, suppose agents a, b and c vouch for d’s credentials, and agents b, d, and e vouch for a’s credentials. Such a sequence of reasoning is circular because a is offering testimony for d but d is offering testimony for a. The paper formulates and evaluates restrictions on the use of testimonial evidence that might be used to (...) deal with such problematic arguments. One is called the Non-repeater Rule: in an extended sequence of argumentation based on testimony, once a source x has been appealed to at any given point in the sequence, that same source x must never be appealed to again at any next point in the same sequence.

Many experiments suggest that participants are more critical of arguments that challenge their views or that come from untrustworthy sources. However, other results suggest that this might not be true of demonstrative arguments. A series of four experiments tested whether people are influenced by two factors when they evaluate demonstrative arguments: how confident they are in the answer being challenged by the argument, and how much they trust the source of the argument. Participants were not affected by their confidence (...) in the answer challenged by the argument. By contrast, they were sometimes affected by their trust in the argument’s source. Analyses of reaction times and transfer problems suggest that source trustworthiness did not directly affect argument evaluation, but affected instead the number of times the participants considered the arguments. Our results thus suggest that people can evaluate demonstrative arguments objectively. In conclusion, we defend the hypothesis that people might also be able to evaluate non-demonstrative arguments objectively. These results support the predictions of the argumentative theory of reasoning. (shrink)

Testimony is an important source of our knowledge about the world. But to some, there seems something odd, perhaps even wrong, about trusting testimony about specifically moral matters. In this paper, I discuss several different explanations of what might be wrong with trusting moral testimony. These include the possibility that there is no moral knowledge; that moral knowledge cannot be transmitted by moral testimony; that there are reasons not to trust moral testimony either because you should try to gain (...) and use “moral understanding” to make your moral judgements instead or because doing so is damaging to your moral character in various ways. Finally, I discuss some “debunking explanations” according to which it is right and rational to trust moral testimony from a trustworthy source. © 2013 The Author.

There is a widely recognized dilemma of political epistemic trust. While the public needs to rely on the testimonies of epistemic authorities (e.g. politicians, policymakers, and scientists), it is risky to do so. One source of risk is self-interest. Epistemic authorities are prone to abuse the trust placed in them by misinforming the public for material and social gain. To reap the benefits of trust and mitigate the risk of abuse, liberal political theorists adopt the strategy of cultivating vigilant (...) trust. By enhancing epistemic vigilance and epistemic autonomy, trust is both constrained and intellectualized. This chapter rejects this strategy for two reasons. First, it is undesirable. By over-intellectualizing trust, such an approach deprives trust of its important epistemic and social benefits. Second, it is unnecessary. The risk of abuse is exaggerated. The strategy fails to appreciate that epistemic authorities in virtue of their social roles are typically governed by the social norm of epistemic trustworthiness, not self-interest. The chapter concludes by suggesting an alternative strategy of cultivating trustworthiness. It seeks to strengthen epistemic authorities’ responsiveness to the social norm of epistemic trustworthiness, thereby improving epistemic trust without over-intellectualizing it. It is further outlined how liberal-democratic institutions can implement it. (shrink)

Previous studies on corporate social responsibility (CSR) communication suggest that firms’ social initiatives should be communicated through third-party, non-corporate sources because they are perceived as unbiased and therefore reduce consumer skepticism. In this article, we extend existing research by showing that source effects in the communication of social sponsorships are contingent on the brand’s pre-existing reputation. We argue that the congruence between the credibility and trustworthiness of the message source and the brand helps predict consumer responses to (...) a social sponsorship. The results show that a non-corporate source (publicity) generates more positive brand evaluations than a corporate source (advertising) when the sponsor has a positive reputation. However, the converse effect occurs when brand reputation is low: when the sponsor has a poor reputation, a corporate source generates more positive brand evaluations than a non-corporate source. Mediation analyses show that the interaction effect between CSR information source and brand reputation can be explained by sponsorship attitude, persuasion knowledge, and perceived fit between the brand and the cause.

Several philosophical issues in connection with computer simulations rely on the assumption that results of simulations are trustworthy. Examples of these include the debate on the experimental role of computer simulations :483–496, 2009; Morrison in Philos Stud 143:33–57, 2009), the nature of computer data Computer simulations and the changing face of scientific experimentation, Cambridge Scholars Publishing, Barcelona, 2013; Humphreys, in: Durán, Arnold Computer simulations and the changing face of scientific experimentation, Cambridge Scholars Publishing, Barcelona, 2013), and the explanatory power of (...) computer simulations :277–292, 2008; Durán in Int Stud Philos Sci 31:27–45, 2017). The aim of this article is to show that these authors are right in assuming that results of computer simulations are to be trusted when computer simulations are reliable processes. After a short reconstruction of the problem of epistemic opacity, the article elaborates extensively on computational reliabilism, a specified form of process reliabilism with computer simulations located at the center. The article ends with a discussion of four sources for computational reliabilism, namely, verification and validation, robustness analysis for computer simulations, a history of successful implementations, and the role of expert knowledge in simulations.

Testimony is an important source of knowledge in many contexts, including that of education, but the notion of the teacher as testifier is not often discussed. Since much that is believed by individuals has come to them not from direct experience but by accepting the accounts of others, the trustworthiness of their interlocutors' testimonies, whether these be spoken, textual or electronic in form, is an important factor in determining whether or not they acquire true, justified beliefs. Testimonial (...) class='Hi'>trustworthiness is a combination of competence and sincerity, both of which tend to be high when a teacher testifies in her area of expertise. But in the world beyond the classroom there are situations in which the competence or sincerity of the testifier is low, so it is important that the learner acquires an epistemically-virtuous, well-attuned disposition towards testimony.

Considering the value of archives for dealing with the past processes, especially for the establishment of collective memory and identity, this paper discusses the role of archives in situations of conflicting memories such as in the case of the official Turkish denial of the Armenian genocide. A crucial problem of Turkish-Armenian reconciliation are the divergent perceptions of what to consider as proper ‘evidence’, i.e. as objective, reliable, impartial or trustworthy sources of knowledge in order to prove the Armenian genocide. The (...) aim of this paper is to show how in a general atmosphere of distrust or prejudiced credibility judgments, even technically reliable archival records will be perceived as unreliable and biased, lacking any evidentiary status to factually prove a genocide which is categorically denied. Therefore, this working paper discusses how claims to reliability, objectivity and other similar scientifically and epistemically relevant attributes are understood in archival science as well as memory studies, and emphasizes the problems related to their instrumentalization by political actors within the context of genocide denialism. The Turkish-Armenian context promises many important empirical as well as theoretical insights on the uses and misuses of these attributes, suggesting that measures ought to be taken beforehand to decrease intergroup prejudice and distrust toward the ‘other’, so that archives can be effective in the truth-finding process.

The 6th Consensus Statement on Concussion in Sport is authored by the Concussion in Sport Group (CiSG) and intends to provide evidence-based recommendations on concussion management for the welfare of sports participants. However, the authors of the Consensus Statement have declared many competing links to third-party groups. While the declaration of an author’s competing interests is now a widely accepted practice within academic publishing aimed at greater transparency and research integrity, it is not a measure to remove the potential influence (...) of third-party links. In the case of the Consensus Statement, this leaves uncertainty about how the potential sources of third-party bias declared by individual members of the CiSG may have influenced the CiSG’s interpretation of the existing state of evidence on concussion management and impacted the content of the recommendations contained with the Consensus Statement. Openly declaring third-party links falls short of securing trustworthiness in the Consensus Statement recommendations since it leaves end-users of the Consensus Statement with the task of interpreting the impact(s) of these competing interests with little information to guide them. This is because the authors themselves offer neither explanation nor guidance concerning potential bias arising from the competing interests that they have declared, which impinges upon the ability of readers to evaluate the trustworthiness of the content. The status quo could be improved by excluding researchers who have conflicts of interest. Nevertheless, if authors with competing interests are permitted to be part of the CiSG (as is the status quo), then I propose a novel option for increasing transparency that would require authors of the Consensus Statements to provide a reflexive explanation, not simply a declaration, of their competing interests.

In a recent paper Weinberg (2007) claims that there is an essential mark of trustworthiness which typical sources of evidence as perception or memory have, but philosophical intuitions lack, namely that we are able to detect and correct errors produced by these “hopeful” sources. In my paper I will argue that being a hopeful source isn't necessary for providing us with evidence. I then will show that, given some plausible background assumptions, intuitions at least come close to being (...) hopeful, if they are reliable. If this is true, Weinberg's new challenge comes down to the claim that philosophical intuitions are not reliable since they are significantly unstable. In the second part of my paper I will argue that and why the experimentally established instability of folk intuitions about philosophical cases does not show that philosopher's expert intuitions about these cases are instable.

Current fears of a “reproducibility crisis” have led researchers, sources of scientific funding, and the public to question both the efficacy and trustworthiness of science. Suggested policy changes have been focused on statistical problems, such as p-hacking, and issues of experimental design and execution. However, “reproducibility” is a broad concept that includes a number of issues. Furthermore, reproducibility failures occur even in fields such as mathematics or computer science that do not have statistical problems or issues with experimental design. (...) Most importantly, these proposed policy changes ignore a core feature of the process of scientific inquiry that occurs after reproducibility failures: the integration of conflicting observations and ideas into a coherent theory.

In “Group Testimony” (2007) I argued that the testimony of a group cannot be understood (or at least cannot always be understood) in a summative fashion; as the testimony of some or all of the group members. In some cases, it is the group itself that testifies. I also argued that one could extend standard reductionist accounts of the justification of testimonial belief to the case of testimonial belief formed on the basis of group testimony. In this paper, I explore (...) the issue of group testimony in greater detail by focusing on one putative source of testimony, that of Wikipedia. My aim is to the answer the following questions: Is Wikipedia a source of testimony? And if so, what is the nature of that source? Are we to understand Wikipedia entries as a collection of testimonial statements made by individuals, some subset of individuals, or is Wikipedia itself (the organization or the Wikipedia community) the entity that testifies? If Wikipedia itself is a source of testimony, what resources do we have for assessing the trustworthiness of such an unusual epistemic source? In answering these questions I hope to further elucidate the nature of collective epistemic agency (Tollefsen 2006), of which group testimony is a paradigm example. When a mans Discourse begineth…at some saying of another, of whose ability to know the truth, and of whose honesty in not deceiving, he doubteth not; and then the Discourse is not so much concerning the Thing, as the Person; and the Resolution is called Beleefe, and Faith: Faith in the man.

In lieu of an abstract, here is a brief excerpt of the content:86 HISTORY OF PHILOSOPHY lamblichi Chalcidensis ex Coele-Syria de vita Pythagorica liber, lamblichos, Pythagoras. Legende--Lehre---Lebensgestaltung. Griechisch und Deutsch, herausgegeben, iibersetzt und eingeleitet von Michael yon Albrecht. (Ziirich & Stuttgart: Artemis, 1963. Pp. 280. = Die Bibliothek der Alten Welt, Reihe Antike und Christentum.) The present edition and translation again makes available one of the texts most valuable for the understanding of the world of late antiquity. The earlier editions, (...) especially that of L. Deubner (1937), are out of print. The fact that this document has been translated into German for the first time is also very helpful, since Iamblichos is sometimes difficult to understand. A brief but nevertheless informative introduction rightly emphasizes that Iamblichos intended to present an introduction and initiation into the Pythagorean way of life rather than a biography of Pythagoras based upon historically trustworthy materials. Although the biography of Pythagoras is certainly a part of the book, it serves only as the ideal example of the Pythagorean way of life, as Iaznblichos sees it. However, more than merely a work of Iamblichos, it ought to be recognized as a "fundamental document of the image of man in later antiquity" (p. 11). The text is based upon L. Deubner's edition, but occasionally it takes up older conjectures or returns to the tradition (for a more detailed discussion cf. W. Burkert, Gnomon 37, 1965, 24ff.). The index and the explanatory notes are also helpful, although the latter prove to be too brief and do not adequately call the reader's attention to the problems of sources, tradition, and composition. One can only agree with von Albrecht that we still need a modem commentary (p. I1). H. D. BETZ Claremont, CaliIornia Agrippa and the Crisis o] Renaissance Thought. By Charles G. Nauert, Jr. (Urbana: University of Illinois Press, 1965. Pp. vi W 374. $8.00.) One of the most influential and widely read thinkers of the early sixteenth century was the German Heinrich Cornelius Agrippa von Nettisheim (1486-1535). His many works were reprinted often, as well as being translated into several vernacular languages. The De incertitudine et vanitate omnium scientiarum et atrium of 1526, for example, went through at least 16 printings before 1700 and appeared in Italian (1547), English (1569), French (1582), and Dutch (1651) translations, which were themselves often reprinted. Although interest in Agrippa has waned somewhat since the seventeenth century, there is still a significant amount of scholarly debate regarding his importance and the meaning of his writings. Professor Nauert's monograph is the fruit of many years' study of Agrippa's life, thought, and milieu. In it he clearly places Agrippa in his historical context, accurately sketching his background and influence. After a brief introduction (pp. 1-7), the study is essentially divided into two parts: The first (pp. 8-115) traces Agrippa's life and intellectual development, the second (pp. 116-334) discusses in some detail a number of the key themes developed in his writings. There is also a substantial bibliography (pp. 335-,355) and a quite complete and accurate index (pp. 357-374). Although the mass of material which Nanert brings to our attention indicates the opposite, one sometimes gets the impression that the author tends to underestimate the importance of his subject. For example, he says, "Agrippa von Nettisheim is now a forgotten figure in the intellectual history of the West" (p. 322), but this does not seem to be the case. Although much work remains to be done, at least five books have been devoted to Agrippa in the past half century and, indeed, at least seven articles have appeared in the past ten years on one or another aspect of his life and thought. The very fact that Nanert can argue with so much vigor against the views of contemporary scholars like Lynn Thomdike and Paola Zambelli indicates that it is anything but a dead issue. As it is, Nauert's book clearly and accurately describes Agrippa's place in the intellectual ambiance of the sixteenth century. It gives the first detailed analysis of Agrippa's life and thought in English in recent BOOK REVIEWS 87 times and is the first full*scale attempt to exhaustively treat... (shrink)

The fact that much of our knowledge is gained through the testimony of others challenges a certain form of epistemic individualism. We are clearly not autonomous knowers. But the discussion surrounding testimony has maintained a commitment to what I have elsewhere called epistemic agent individualism. Both the reductionist and the anti-reductionist have focused their attention on the testimony of individuals. But groups, too, are sources of testimony - or so I shall argue. If groups can be testifiers, a natural question (...) to ask is whether our beliefs based on the testimony of groups are ever justified and whether such a justification is to be conferred inferentially or non-inferentially. I consider and dismiss the possibility of extending an anti-reductionist account of justification to our group testimonial beliefs. I also argue against a version of reductionism that would have our group testimonial beliefs justified only in so far as we were able to monitor the trustworthiness of members of the group. However, there are forms of reductionism that can be extended to make sense of the justification of our group testimonial beliefs. There are mechanisms for monitoring the trustworthiness and competency of a group (rather than its members) and, further, a variety of background beliefs allow us to assess the testimony of a group for reliability.

Science is a collaborative effort to produce knowledge. Scientists thus must assess what information is trustworthy and who is a competent and honest source and partner. Facing the problem of trust, we can expect scientists to be vigilant. In response to their peers’ vigilance scientists will provide reasons, not only to convince their colleagues to adopt their practices or beliefs, but also to demonstrate that their beliefs and practices are justified. By justifying their beliefs and practices, scientists also justify (...) themselves. Reasons in science thus do not only function as tools of persuasion but also to manage reputation. This analysis strongly suggests that science constitutes a moral system, which has implications for the study and philosophy of science. (shrink)

Some solo verbal reasoning serves the function of arriving at a correct answer to a question from information at the reasoner’s disposal. Such reasoning is good if and only if its grounds are justified and adequate, its warrant is justified, and the reasoner is justified in assuming that no defeaters apply. I distinguish seven sources of justified grounds and state the conditions under which each source is trustworthy. Adequate grounds include all good relevant information practically obtainable by the reasoner. (...) The claim must follow from the grounds in accordance with a justified general warrant. If this warrant is not universal, the reasoner must be justified in assuming that no exception-making circumstances hold in the particular case to which it is applied. (shrink)

In this paper, we reconsider the notion of epistemic trespassing and attempt to explore possible scenarios in which it could lead to positive outcomes in scientific research and information dissemination. As we will point out, some of the significant discoveries in the history of science would not have been possible were it not for the epistemic trespassers, whose shift in paradigm changed the approach to specific issues for the better. Furthermore, we will present instances where individuals, often labeled as ‘trespassers’ (...) – those who venture into fields outside their expertise – can be considered trustworthy and reliable sources of testimony. Consequently, epistemic trespassing turned out to be essential for the advancement of science. Epistemic trespassing in our age is virtually inevitable – whether it be from a political perspective (to preserve democratic values) or due to purely practical reasons (i.e. searching for information online). There are interdisciplinary fields where a strictly negative characterization of epistemic trespassing would question their methodology since these disciplines rely on experts from various fields. For these reasons, we advocate for a more charitable approach to epistemic trespassing and greater public education to help them distinguish between correct and false information. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Forgeries and Art Evaluation:An Argument for Dualism in AestheticsTomas Kulka (bio)If a fake is so expert that even after the most thorough and trustworthy examination its authenticity is still open to doubt, is it or is it not as satisfactory a work of art as if it were unequivocally genuine? 1It is a wonderful moment in the life of a lover of art when he finds himself suddenly confronted (...) with a hitherto unknown painting by a great master, untouched, on the original canvas, and without any restoration, just as it left the painter's studio. And what a picture! Neither the beautiful signature... nor the pointillé on the bread which Christ is blessing, is necessary to convince us that we have here—I am inclined to say—the masterpiece of Johannes Vermeer of Delft... quite different from all his other paintings and yet every inch a Vermeer. In no other picture by the great master of Delft do we find such sentiment, such a profound understanding of the Bible story—a sentiment so nobly human expressed through the medium of highest art.2The author of these lines is Professor Abraham Bredius, the nestor of Holland's art historians and the greatest authority on seventeenth-century Dutch painting. The source is The Burlington Magazine for Connoisseurs, the most prestigious periodical for the history of art of the period. The year is 1937. The painting, however, is not a masterpiece of Vermeer but a fake produced by the mediocre Dutch artist Han van Meegeren.The Problem of ForgeryMany art dealers have been financially ruined, and many art historians academically discredited, because of incorrect attribution. Apart from the practical problems that worry curators and art historians, there is also a theoretical problem, which has become a subject of heated discussions since the late 1960s. The dispute gained a momentum with the publication of Nelson Goodman's Languages of Art. In its third chapter titled "Art and Authenticity," [End Page 58] which put the problem of forgeries on the agenda of contemporary aesthetics, Goodman states that a "philosopher of art caught without an answer to [the] question... why there is any aesthetic difference between a deceptive forgery and an original work... is at least as badly off as a curator of paintings caught taking a Van Meegeren Vermeer for a Vermeer."3Although the literature on the problem of forgeries is extensive, the answers that have been put forward fall roughly into three categories: the formalist answer, which states that there is no aesthetic difference between an original painting and a deceptive forgery; the reductionist answer, which claims that there is such a difference and that it can be traced to the minute physical differences between originals and its copies; and the historicist answer, which also asserts that there must be an aesthetic difference but claims that it stems from the different histories of the two objects.The most prominent proponent of the formalist approach is Monroe C. Beardsley. His theory is based on the assumption that "two objects that do not differ in any observable qualities cannot differ in aesthetic value."4 Aesthetic formalism, as the name suggests, maintains that works of art should be judged according to their form. Only the visual features of the painted surface—the configuration of its lines and colors, composition, spatial relations, texture, design, etc., are relevant for its appreciation. The subject of our evaluation is the finished product, not the information pertaining to the history of its production. Who, when, and where painted the picture, just like the intentions of the painter, are irrelevant for the assessment of its aesthetic qualities. Only the "internal" properties, that is, the properties of the "work itself," count. The "external" properties, by which Beardsley means anything that "relates to something existing before the work itself, to the manner in which it was produced, or its connection to antecedent objects," have no bearing on aesthetic value. Hence the conclusion that if fakes resemble the original "in their internal characteristics, so that no one could tell them apart just by looking at them" there can be no aesthetic difference between them.5 Originality is thus excluded...

In light of recent advances in machine learning for medical applications, the automation of medical diagnostics is imminent. That said, before machine learning algorithms find their way into clinical practice, various problems at the epistemic level need to be overcome. In this paper, we discuss different sources of uncertainty arising for clinicians trying to evaluate the trustworthiness of algorithmic evidence when making diagnostic judgments. Thereby, we examine many of the limitations of current machine learning algorithms (with deep learning in (...) particular) and highlight their relevance for medical diagnostics. Among the problems we inspect are the theoretical foundations of deep learning (which are not yet adequately understood), the opacity of algorithmic decisions, and the vulnerabilities of machine learning models, as well as concerns regarding the quality of medical data used to train the models. Building on this, we discuss different desiderata for an uncertainty amelioration strategy that ensures that the integration of machine learning into clinical settings proves to be medically beneficial in a meaningful way.

Whether out of an understandable reluctance to neglect any of the scarce available sources or simply for want of more trustworthy evidence, classical scholars nolentes volentes tend to rely to a large extent on references to amounts of money in the ancient literary sources whenever they aim at quantifying, however roughly and shielded by appropriate disclaimers, some fundamental features of Roman economy and society. In view of this, the almost complete lack of systematic enquiries into the very nature of these (...) particular data is almost as inexplicable as it seems inexcusable. While several studies have been devoted to the use of rounded numbers in Greek and Roman literature in general, none of these has specifically addressed the stylization of monetary valuations. The only notable exception is provided by the work of Richard Duncan-Jones who in a pioneering survey of prices in the Latin novel above all showed beyond reasonable doubt that in this genre, prices expressed in multiples of thirty should best be understood as purely conventional valuations. In his latest book, he has subjected the ancient numerical evidence for two areas of major concern—the public treasury and state expenditure during the Principate—to an analogous examination that has highlighted the stylized character of many relevant references and has thus largely confirmed his previous findings. Even so, owing to the limitation of these studies to a small number of authors and subject matters, a vast pool of similar data from ancient literature has hitherto been left virtually untapped. What is more, Duncan-Jones did not attempt to complement his re-evaluation of multiples of thirty with a systematic exposition of complementary patterns of stylization. In this paper, I hope to demonstrate the need for a more extensive and much more radical reassessment of much of the available evidence. (shrink)

How can one establish if a corporate code of ethics is ethical in terms of its content? One important first step might be the establishment of core universal moral values by which corporate codes of ethics can be ethically constructed and evaluated. Following a review of normative research on corporate codes of ethics, a set of universal moral values is generated by considering three sources: (1) corporate codes of ethics; (2) global codes of ethics; and (3) the business ethics literature. (...) Based on the convergence of the three sources of standards, six universal moral values for corporate codes of ethics are proposed including: (1) trustworthiness; (2) respect; (3) responsibility; (4) fairness; (5) caring; and (6) citizenship. Relying on the proposed set of universal moral values, implications are discussed as to what the content of corporate codes of ethics should consist of. The paper concludes with its limitations.

This paper examines the success of corporate communication in voluntary sustainability reporting. Existing studies have focused on the perspective of the communicators but lack an understanding of the perspective of information recipients to clearly evaluate this interactive communication process. This paper looks at the issue of a credibility gap perceived by external stakeholders when they doubt the authenticity of communicated information due to the reporting company’s governance structure. The paper uses family businesses to exemplify the emergence of such a gap (...) when outsiders become concerned about the potential agency problem of the integrated ownership and management controlled by a few members of the same family. Following source credibility theory, these concerns raise a credibility gap associated with a family firm’s trustworthiness and goodwill, even if the family has the expertise to carry out sustainability reporting. The findings of two experimental studies indicate that family businesses suffer a greater credibility gap than non-family businesses. An external and independent assurance service can mitigate such gaps, especially when the service is comprehensive and targets family businesses. The paper provides a complete view evaluating corporate communication by looking at the interaction between the communicating company and the information recipients. (shrink)

The writings of the Scottish physician and philosopher John Gregory play an important role in the modern codification of medical ethics. It is therefore appropriate to use his work as a historical example in approaching the question how elements of aesthetics were incorporated in 18th century medical ethics. The concept of a Gentleman is pivotal to the entire medical ethics of John Gregory as it provides him with the ethical source of the duty to patients. Gregory makes the (...) class='Hi'>trustworthiness of the physician a central point of his medical ethics, and it is in this context that Gregory declares good manners as an essential moral quality of a physician. This paper delineates how good manners are ethically justified in Gregory's medical ethics and concludes with an exploration of the importance of Gregory's conception for present day reflection on the inherence of aesthetics in ethical determinations.
