I discuss under what conditions the objection that an expert’s argument is biased by her self-interest can be a meaningful and sound argumentative move. I suggest replacing the idea of bias qua self-interest by that of a conflict of interests, exploit the distinction between an expert context and a public context, and hold that the objection can be meaningful. Yet, the evaluation is overall negative, because the motivational role of self-interest for human behavior remains unclear. Moreover, if recent social-psychological results (...) from the “heuristics and biases” program are accepted, it is plausible to assume that humans also satisfice (rather than optimize/maximize) when identifying and then acting in their self-interest. My thesis is: insofar as the objection is sound with a particular audience, it is not needed; and insofar as the objection is needed, it is unsound. (shrink)

To become an expert in a technical domain means acquiring the tacit knowledge pertaining to the relevant domain of expertise, at least, according to the programme known as “Studies of Expertise and Experience” (SEE). We know only one way to acquire tacit knowledge and that is through some form of sustained social contact with the group that has it. Those who do not have such contact cannot acquire the expertise needed to make technical judgments. They can, however, use social expertise (...) to judge between experts or expert claims. Where social expertise is used to make technical judgments we refer to it as “transmuted expertise”. The various kinds of transmuted expertise are described and analysed. (shrink)

This article seeks, first, to show that much of the existing normative work on argument from expert opinion (AEO) is problematic for failing to be properly informed by empirical findings on expert performance. Second, it seeks to show how, with the analytic tool of Bayesian reasoning, the problem diagnosed can be remedied to circumvent some of the problems facing the scheme-based treatment of AEOs. To establish the first contention, we will illustrate how empirical studies on factors conditioning expert reliability can (...) be drawn upon to re-construct. Walton’s critical questions matching the scheme of AEOs. To establish the second contention, we will illustrate how Walton’s re-constructed set of critical questions can be formalized within a Bayesian network. Finally, we will highlight how the specific ways in which the Bayesian framework we propose is both continuous with and distinct from the models of source reliability put forward by theorists like Bovens and Hartmann (2003).

In one of his papers, Moti Mizrahi argues that arguments from an expert opinion are weak arguments. His thesis may seem controversial due to the consensus on this topic in the field of informal logic. I argue that its controversy is framework-dependent, and if translated into a different framework, it appears to be a correct, however trivial, claim. I will use a framework based on Douglas Walton’s argumentation scheme theory and his conception of examination dialogue to demonstrate that it is (...) so. It appears that Mizrahi’s idiosyncratic framework provides an excessively restrictive conception of an argument from expert opinion than Walton’s scheme does. There is no quarrel between both frameworks, as they yield analogous, almost identical, outcomes of argument evaluation. The actual and crucial disagreement is on the topic of argument classification. Mizrahi’s conception of arguments from an expert opinion imposes exact conditions that such argument must fulfil: an expert’s opinion o truth-value must be unknown; o must be unsupported by any evidence; an expert’s peers neither accept o nor reject it. These exclude, by definition, every possible strong, in Walton’s terms, variant of such an argument. Therefore, if rephrased with the notions of the examination dialogue framework, Mizrahi’s thesis sounds as follows: weak arguments from expert opinion are weak arguments. (shrink)

In this paper it is shown how certain defeasible argumentation schemes can be used to represent the logical structure of the most common types of argument used for statutory interpretation both in civil and common law. The method is based on an argumentation structure in which the conclusion, namely, the meaning attributed to a legal source, is modeled as a claim that needs that is be supported by pro and con defeasible arguments. The defeasible nature of each scheme is shown (...) by means of critical questions, which identify the default conditions for the accepting interpretative arguments and provide a method for evaluating a given argument as weak or strong.

Expertise is commonly viewed as a professionalized competence in a specific field. Expert professional identities are produced and reproduced through professional training and other socialization mechanisms, which work to generate for a specific group of individuals a specific set of expert skills and knowledge. In this paper, I examine participants’ orientations to their distinct expert professional identities from the perspective of deontic authority. Drawing on 15 video-recorded church workplace meetings between pastors and cantors as data, and conversation analysis as a (...) theoretical and methodological framework, I analyze situations where a non-expert participant makes a proposal that the expert participant orients to as reasonable to comply with. Specifically, I demonstrate how the expert participants respond to these proposals with displays of deontic authority, arguably in an attempt to maintain their expert identities in the face of their de facto compliance with the proposals. In these situations, the expert participants are shown to invoke a past decision of their own, a future decision of their own, or a pattern that is beyond both participants’ control. Each of these practices involves the expert participant balancing resistance and compliance by minimally acknowledging the content of the non-expert participant’s proposal, while excluding the non-expert from those who have deontic authority in the matter. In so doing, the expert speaker implies that the non-expert proposal speaker lacks procedural knowledge about the specific matters about which it is relevant to make proposals to experts and access to the distinct experiential perspective that characterizes expert perception of things. It is thus argued that, in this context, the mere claims of deontic authority, produced without any substantial displays of expert knowledge, can serve the maintenance of expert professional identities.

Ethotic arguments, such as arguments from expert opinion and ad hominem arguments, play an important role in communication practice. In this paper, we argue that there is another type of reasoning from ethos, in which people argue about actions in the world. These subspecies of ethotic arguments are very common in public debates: societies are involved in heated disputes about what should be done with monuments of historical figures such as Stalin or Colston: Should we demolish the building they funded? (...) Should we revere their statues? Should the street named after them be renamed?; and the general public vividly argue about what should be done with the legacy of producers, directors and actors in debates of the #MeToo movement: Should their new movies be distributed? Should their scenes be deleted from motion pictures? Should their stars from the Hollywood Walk of Fame be removed? Many arguments in these debates boil down to the character of the public figures: He was a slave trader!—But he is a part of our history; He harassed a young girl!—But he is an important actor. The reasoning step here is legitimised by the association between a person and an extra-linguistic object: the association between a historical figure and their statue or between an actor and their movie. The nature of this association is explained in the paper using Peirce’s theory of signs. We propose to extend an existing approach to patterns of reasoning from ethos that will help us to shed new light on ethotic argumentation and open an avenue for a systematic account of these unexplored argument forms.

Douglas Walton’s multitudinous contributions to the study of argumentation seldom, if ever, directly engage with argumentation in mathematics. Nonetheless, several of the innovations with which he is most closely associated lend themselves to improving our understanding of mathematical arguments. I concentrate on two such innovations: dialogue types (§1) and argumentation schemes (§2). I argue that both devices are much more applicable to mathematical reasoning than may be commonly supposed.

Kann Vertrauen in einen Sprecher, kann die Anerkennung einer anderen Person als eine epistemische Autorität nicht auch ein hinreichend guter Grund sein, eine Überzeugung zu rechtfertigen? Und wenn es diese theoretische Option gibt, ist sie im Kontext der Kommunikation zwischen wissenschaftlichen Laien und wissenschaftlichen Experten plausibel? Diesen Fragen geht der Aufsatz in drei Schritten nach. Der erste Teil dient der Klärung des Begriffes »Vertrauen« und arbeitet wesentliche Merkmale dieser mentalen Einstellung heraus. Dies geschieht in der Abgrenzung zum Begriff des Sich-Verlassens, (...) und zwar einerseits hinsichtlich der Objekte, auf die die jeweiligen Einstellungen Bezug nehmen, andererseits hinsichtlich der Gründe, die das Einnehmen der jeweiligen Einstellung rechtfertigen. Anschließend werden etablierte Theorien der Rechtfertigung von Überzeugungen aus dem Zeugnis anderer daraufhin untersucht, welche epistemische Funktion ein so geschärfter Vertrauensbegriff in ihrem Rahmen spielen kann. Es zeigt sich, dass nur die sogenannten Zusicherungstheorien die begrifflichen Ressourcen haben, Vertrauen in eine andere Person als Rechtfertigungsgrund für testimoniale Überzeugungen zu erklären. Im letzten Teil wende ich mich schließlich der Frage zu, ob und inwiefern das Modell der Zusicherungstheorie auf die Kommunikation zwischen Experten und Laien übertragen werden kann und zeige kritisch auf, weshalb einschlägige Behandlungen der Frage in Wissenschaftsphilosophie und Sozialpsychologie von diesem Modell abweichen.

The analysis of multimodal argumentation in advertising is a crucial and problematic area of research. While its importance is growing in a time characterized by images and pictorial messages, the methods used for interpreting and reconstructing the structure of arguments expressed through verbal and visual means capture only isolated dimensions of this complex phenomenon. This paper intends to propose and illustrate a methodology for the reconstruction and analysis of “double-mode” arguments in advertisements, combining the instruments developed in social semiotics, pragmatics, (...) and argumentation theory. An advertisement is processed through a five-step path. The analysis of its context, text genre, and images leads to a first representation of the messages that it encodes both pictorially and verbally (step 1). These first semantic representations are further enriched by including their polyphonic articulations and presuppositions (step 2), their explicatures (step 3), and their dialogical functions and illocutionary forces (step 4). These pragmatic steps retrieve the commitment structure of the ad, which allows a further argument analysis conducted through argumentation schemes (step 5). (shrink)

Epistemic democrats are rightly concerned with the quality of outcomes and judge democratic procedures in terms of their ability to ‘track the truth’. However, their impetus to assess ‘rule by experts’ and ‘rule by the people’ as mutually exclusive has led to a meagre treatment of the role of expert knowledge in democracy. Expertise is often presented as a threat to democracy but is also crucial for enlightened political processes. Contemporary political philosophy has so far paid little attention to our (...) reliance on experts and has not sufficiently addressed the question of how expertise can be used to improve the epistemic quality of democratic decision making. We believe this lack of interest is spurred by a too hasty acceptance of arguments dismissive of the political role of experts. The article examines a series of often-cited epistemic objections and concludes that several of them are overstated or misconceived, yet they all reflect real difficulties that need to be addressed. On this background, we tentatively outline a set of mechanisms that can contribute to alleviating the irreducible problem of epistemic asymmetries and ensuring that experts really are experts and use their expertise in the right way.

Despite being a new term, ‘fake news’ has evolved rapidly. This paper argues that it should be reserved for cases of deliberate presentation of false or misleading claims as news, where these are misleading by design. The phrase ‘by design’ here refers to systemic features of the design of the sources and channels by which fake news propagates and, thereby, manipulates the audience’s cognitive processes. This prospective definition is then tested: first, by contrasting fake news with other forms of public (...) disinformation; second, by considering whether it helps pinpoint conditions for the proliferation of fake news.

Contemporary reasoning about health is infused with the work products of experts, and expert reasoning about health itself is an active site for invention and design. Building on Toulmin’s largely undeveloped ideas on field-dependence, we argue that expert fields can develop new inference rules that, together with the backing they require, become accepted ways of drawing and defending conclusions. The new inference rules themselves function as warrants, and we introduce the term “warranting device” to refer to an assembly of the (...) rule plus whatever material, procedural, and institutional resources are required to assure its dependability. We present a case study on the Cochrane Review, a new method for synthesizing evidence across large numbers of scientific studies. After reviewing the evolution and current structure of the device, we discuss the distinctive kinds of critical questions that may be raised around Cochrane Reviews, both within the expert field and beyond. Although Toulmin’s theory of field-dependence is often criticized for its relativism, we find that, as a matter of practical fact, field-specific warrants do not enjoy immunity from external critique. On the contrary, they can be opened to evaluation and critique from any interested perspective. (shrink)

ABSTRACTIn everyday situations, people regularly receive information from large groups of people and from single experts. Although lay opinions and expert opinions have been studied extensively in isolation, the present study examined the relationship between the two by asking how many laypeople are needed to counter an expert opinion. A Bayesian formalisation allowed the prescription of this quantity. Participants were subsequently asked to assess how many laypeople are needed in different situations. The results demonstrate that people are sensitive to the (...) relevant factors identified for determining how many lay opinions are required to counteract a single expert opinion. People's assessments were fairly good in line with Bayesian predictions. (shrink)

This paper discusses the conditions for legitimate expert arrangements within a democratic order and from a deliberative systems approach. It is argued that standard objections against the political role of experts are flawed or ill-conceived. The problem that confronts us instead is primarily one of truth-sensitive institutional design: Which mechanisms can contribute to ensuring that experts are really experts and that they use their competencies in the right way? The paper outlines a set of such mechanisms. However, the challenge exceeds (...) that of producing epistemically optimal expert deliberations because a deliberative political system must also fulfil the ethical and democratic requirements of respect and inclusion. Yet, epistemic concerns justify expertise arrangements in the first place, and measures taken to make the use of expertise compatible with these requirements have to balance the potential rewards from expertise against potential deliberative costs. In the final part of the paper, the regulatory framework of a best practice expert advice system is tentatively analysed to illustrate the applicability and critical potential of our approach.

In this article author traces relation between argumentation and cultural practice. The first part focuses on definition of argumentation in informal logic tradition. In particular, it discusses argument in terms of verbal and social activity involving the use of everyday language. Author claims that there is no argumentation beyond language. The second part explains persuasive argumentation as a form of cultural practice. The persuasive arguments found in “social practice” can be understood as a social activity, analysable within the context of (...) a given cultural system. Author refers to an approach taking the argumentative expression as a certain type of communicative practice, directed towards respecting, recognising or accepting specific actions. The inclusion of persuasive argumentation in the “circuit of cultural activities” to be studied makes it possible to compare this type of argumentation with other social practices, and to posit a clear historical dimension in the study of argumentation. It also makes it possible to view persuasive argumentation as one of many cultural activities aimed at changing or perpetuating behaviours, attitudes, thinking, etc. The third part of the paper concerns the problem of humanistic interpretation of persuasive argumentation. Author attempts to develop this intuition, at the same time demonstrating the problems that arise from this approach. In conclusion, author tries to analyze argumentation in terms of culture theory and humanistic interpretation. (shrink)

The quality of our public discourse – think of the climate change debate for instance – is never very high. A day spent observing it reveals a litany of misrepresentation and error, argumentative fallacy, and a general lack of good will. In this paper I focus on a microcosmic aspect of these practices: the use of two types of argument – the argumentum ad hominem and appeal to authority – and a way in which they are related. Public debate is (...) so contaminated by the misuse of the ad hominem tactic that it is important to have an understanding of one of the ways in which its use may be legitimate. So readers who might have expected an analysis of the ad hominem fallacy will, on the contrary, be presented with an account of one of the places for its potential success. In ad hominem, arguers are viewed as legitimate constitutive targets for their own argument; in authority arguments, arguers provide a legitimate constitutive warrant for an argument they deploy. These types of argument are connected in so far as the identities of persons deploying them carry the cognitive weight of the argument. If authority arguments sometimes deserve to succeed, ad hominem attacks on them are potentially legitimate. An important motivation for this analysis is that in identifying the success conditions for one of the ad hominem types we attain some clarity in the evaluation of their use. (shrink)

In this paper, I will try to answer the question: How are we supposed to assess the expert’s opinion in an argument from the position of an outsider to the specialized field? by placing it in the larger context of the political status of epistemic authority. In order to do this I will first sketch the actual debate around the problem of expertise in a democracy and relate this to the issue of the status of science in society. Secondly, I (...) will review how Douglas Walton’s pragma-dialectical approach offers a practical procedure to assess the expert bias from a nonprofessional’s perspective. Thirdly, I will introduce the problem of group bias using insights from Bohman and Fischer and show how Walton’s solution does not address this specific type of bias. Lastly, I will try proposing a revision of Walton’s solution in order to address this problem. In order to make the explanation more easy to follow I will use a case study concerning the medical expertise in the public debate on second-hand smoke. (shrink)

In this paper, it is argued that the most fruitful approach to developing normative models of argument quality is one that combines the argumentation scheme approach with Bayesian argumentation. Three sample argumentation schemes from the literature are discussed: the argument from sign, the argument from expert opinion, and the appeal to popular opinion. Limitations of the scheme-based treatment of these argument forms are identified and it is shown how a Bayesian perspective may help to overcome these. At the same time, (...) the contributions of the standard scheme-based approach are highlighted, and it is argued that only a combination of the insights of different traditions will yield a complete normative theory of argument quality.

The present essay discusses a notorious rhetoric means familiar to all scholars in the social sciences and humanities including philosophy: name-dropping. Defined as the excessive over-use of authoritative names, I argue that it is a pernicious practice leading to collective disorientation in spoken discourse. First, I discuss name-dropping in terms of informal logic as an ad verecundiam-type fallacy. Insofar this perspective proves to lack contextual sensitivity, name-dropping is portrayed in Goffman’s terms as a more general social practice. By narrowing down (...) the focus to social science and the humanities, the essay emphasizes its function of discursive legitimation. This view, I argue, is incomplete because it overlooks the basic mechanism beneath. Names not only provide legitimation of but also orientation in discourse. Consequently, two tipping points—detour and disorientation—are proposed as benchmarks for it to become problematic. The conclusion re-widens the argument’s scope by suggesting questions for future inquiries. (shrink)

The thesis of the paper holds that some future developments of argumentation theory may be inspired by the rich logico-methodological legacy of the Lvov–Warsaw School (LWS), the Polish research movement that was most active from 1895 to 1939. As a selection of ideas of the LWS which exploit both formal and pragmatic aspects of the force of argument, we present: Ajdukiewicz’s account of reasoning and inference, Bocheński’s analyses of superstitions or dogmas, and Frydman’s constructive approach to legal interpretation. This paper (...) does not aim at exhaustive elaboration of any of these topics or their usefulness in current discussions within argumentation theory. Rather, we intend to indicate chosen directions of a potentially fruitful research program for the emerging Polish School of Argumentation which would consist in application of methods and conceptions elaborated by the LWS to selected open problems of contemporary research on argumentation.

Richard Whately’s views of arguments involving authority are very different in his Elements of Rhetoric and his Elements of Logic. This essay begins by documenting these differences and wondering why they are. It then proceeds to take a broader and more historical view of Whately’s discussions of authority and finds him occupying an important developmental ground between his predecessor Locke and contemporary views of the argument from authority. In fact, some of the things we now think are important in a (...) good argument from authority are anticipated by Whately. (shrink)

False dilemma is a specific form of reasoning : despite the fact that it is based on a deductively valid argument form, it is rightly depicted as fallacy. A systematic exposition of false dilemma is missing in theoretical approaches to fallacies. This article formulates six criteria for a well-grounded exposition of a fallacy, suggesting also a systematic exposition of false dilemma. These criteria can be used to both explain, and categorise, the various false dilemma fallacies. The article introduces distinction between (...) four types of false dilemma : False quandary, Defeasible sound quandary, False obstruction and Defeasible sound obstruction. The types of criticism appropriate for each variant of false dilemma are suggested. Being able to discover false dilemma in situations when it is important to make good and free choices is a significant dimension of critical thinking. It may liberate us from accepting the consequences that necessarily follow from prearranged alternatives, when these are not the only alternatives possible. It may also liberate us from refraining from actions on the basis of obstructive disjunctive statements. In that respect, the faculty of critical thinking directed at uncovering reasoning based on false dilemma may also initiate the discovery of new alternatives, or discover the ways of unifying seemingly opposing alternatives. Thus, a well-developed ability to understand the tricky argumentative moves of false dilemma may be a good step towards initiating some features of creative thinking. (shrink)

Although argumentation plays an essential role in our lives, there is no integrated area of research on the psychology of argumentation. Instead research on argumentation is conducted in a number of separate research communities that are spread across disciplines and have only limited interaction. With a view to bridging these different strands, we first distinguish between three meanings of the word ?argument?: argument as a reason, argument as a structured sequence of reasons and claims, and argument as a social exchange. (...) All three meanings are integral to a complete understanding of human reasoning and cognition. Cognitive psychological research on argumentation has focused mostly on the first and second of these meanings, so we present perspectives on argumentation from outside of cognitive psychology, which focus on the second and third. Specifically, we give anoverview of the methods, goals, and disciplinary backgrounds of research on the production, the analysis, and the evaluation of arguments. Finally, inintroducing the experimental studies included in this special issue, which were conducted by researchers from a range of theoretical backgrounds, weunderline the breadth of argumentation research as well as stress opportunities for mutual awareness and integration.

In this contribution, I will develop a comprehensive tool for the reconstruction and evaluation of argumentation from expert opinion. This is done by analyzing and then combining two dialectical accounts of this type of argumentation. Walton’s account of the ‘appeal to expert opinion’ provides a number of useful, but fairly unsystematic suggestions for critical questions pertaining to argumentation from expert opinion. The pragma-dialectical account of ‘argumentation from authority’ offers a clear and systematic, but fairly general framework for the reconstruction and (...) evaluation of this type of argumentation. The tool is developed by incorporating Walton’s critical questions into a pragma-dialectical framework. (shrink)

Despite increasing interest in studying arguments from deontic authority of the general form “(1) \(\delta\) is a deontic authority in institution \(\varOmega\) ; (2) according to \(\delta\), I should do \(\alpha\), _C_: therefore, (3) I should do \(\alpha\) ”, the state of the art models are not capable of grasping their complexity. The existing sets of critical questions assigned to this argumentation scheme seem to conflate two problems: whether a person is subject to an authority of an institution in the (...) first place and whether the command issued within the context of a particular institution is eventually binding. For this reason, we introduce (1) a set of Basic Critical Questions to scrutinize the former issue, and (2) a set of more detailed questions related to specific features, also referred to as “parameters”, of institutional environments (Intra-Institutional Critical Questions). We identify major elements of institutional environments in which authoritative utterances are made and the crucial parameters of arguments from deontic authority. The selected evidence from the decisions of the Polish Supreme Administrative Court helps us show how these parameters may be used to reconstruct subtypes of this argument scheme, with their associated sets of critical questions. In specific institutional contexts, such detailed schemes are capable of grasping the complexity of appeals to deontic authority and thus should be used rather than general schemes. The reconstruction of argumentation schemes with critical questions shows how particular arguments may successfully be attacked. (shrink)

In their book Commitment in Dialogue, Walton and Krabbe claim that formal dialogue systems for conversational argumentation are “not very realistic and not easy to apply”. This difficulty may make argumentation theory less well adapted to be employed to describe or analyse actual argumentation practice. On the other hand, the empirical study of real-life arguments may miss or ignore insights of more than the two millennia of the development of philosophy of language, rhetoric, and argumentation theory. In this paper, we (...) propose a novel methodology for adapting such theories to serve as applicable tools in the study of argumentation phenomena. Our approach is both theoretically-informed and empirically-grounded in large-scale corpus analysis. The area of interest are appeals to ethos, the character of the speaker, building upon Aristotle’s rhetoric. Ethotic techniques are used to influence the hearers through the communication, where speakers might establish, but also emphasise, weaken or undermine their own or others’ credibility and trustworthiness. Specifically, we apply our method to Aristotelian theory of ethos elements which identifies practical wisdom, moral virtue and goodwill as components of speakers’ character, which can be supported or attacked. The challenges we identified in this case and the solutions we proposed allow us to formulate general guidelines of how to exploit rich theoretical frameworks to the analysis of the practice of language use.

Appeals to authority have a long tradition in the history of argumentation theory. During the Middle Age they were considered legitimate and sound arguments, but after Locke’s treatment in the Essay Concerning Human Understanding their legitimacy has come under question. Traditionally, arguments from authority were considered informal arguments, but since the important work of Charles Hamblin many attempts to provide a form for them have been done. The most convincing of them is the presumptive form developed by Douglas Walton and (...) John Woods that aims at taking into account the relevant contextual aspects in assessing the provisional validity of an appeal to authority. The soundness of an appeal depends on its meeting the adequacy conditions set to scrutinize all the relevant questions. I want to claim that this approach is compatible with the analysis of arguments in terms of relevance advanced by David Hitchcock. He claims that relevance is a triadic relation between two items and a context. The first item is relevant to the second one in a given context. Different types of relevance relation exist, namely causal relevance and epistemic relevance. “Something is [causally] relevant to an outcome in a given situation if it helps to cause that outcome in the situation”, whereas it is epistemically relevant when it helps to achieve an epistemic goal in a given situation. I claim that we can adapt this conception to Walton and Krabbe’s theory of dialogue type, seeing the items of a relevance relation as the argument and its consequence and the context as the type of dialogue in which these arguments are advanced. According to this perspective, an argument from authority that meets the adequacy conditions has to be considered legitimate because it is an epistemically relevant relation. Therefore, my conclusion is that an analysis of appeals to authority in terms of relevance can be a useful tool to establish fallaciousness or legitimacy of such a kind of argument even within the established paradigm of argumentation theory.

This volume presents a selection of papers reflecting key theoretical issues in argumentation theory. Its six sections are devoted to specific themes, including the analysis and evaluation of argumentation, argument schemes and the contextual embedding of argumentation. The section on general perspectives on argumentation discusses the trends of empiricalization, contextualization and formalization, offers descriptions of the analytical and evaluative tools of informal logic, and highlights selected principles that argumentation theorists do and do not agree upon. In turn, the section on (...) linguistic approaches to argumentation focuses on the problem of distinguishing between explanation and argument, while also elaborating on the role of verbal indicators of argument schemes. All essays included in this volume point out notable recent developments in the study of argumentation. (shrink)

I consider some uses of citations in academic writing and analyze them as instances of the “appeal to expert opinion” argumentative scheme to show that the critical questions commonly linked to this scheme are difficult to apply. I argue that, by considering citations as special communicative and argumentative situated acts, their use in real practice can be explained more adequately. Adaptation to the audience and to the social constraints is common and necessary in order to collaborate with others and to (...) advance in a discipline, but also to attain rhetorical goals that differ from strictly cognitive ones.

Popular textbook treatments of the fallacies approach to argument evaluation employ the Adversary Method identified by Janice Moulton (1983) that takes the goal of argumentation to be the defeat of other arguments and that narrows the terms of discourse in order to facilitate such defeat. My analysis of the textbooks shows that the Adversary Method operates as a Kuhnian paradigm in philosophy, and demonstrates that the popular fallacies pedagogy is authoritarian in being unresponsive to the scholarly developments in informal logic (...) and argumentation theory. A progressive evolution for the fallacies approach is offered as an authoritative alternative. (shrink)

Science progresses through debate and disagreement, and scientific controversies play a crucial role in the growth of scientific knowledge. However, not all controversies and disagreements are progressive in science. Sometimes, controversies can be pseudoscientific; in fact, bogus controversies, and what seem like genuine scientific disagreements, can be a distortion of science set up by non-scientific actors. Bogus controversies are detrimental to science because they can hinder scientific progress and eventually bias science-based decisions. The first goal of this paper is to (...) elucidate the distinction between bogus and genuine scientific controversies and provide a qualitative methodology, based on the literature on expertise, for distinguishing between the two. We will illustrate six epistemic criteria for distinguishing bogus from genuine scientific debates in science and medicine. This heuristic strategy applies directly to scientific reports, and it relies mostly on the social structure of science. We will then apply the above criteria to a case study: the controversy over statins, which are widely prescribed drugs for reducing the level of cholesterol and preventing cardiovascular disease.

This volume reflects the development and theoretical foundation of a new paradigm for critical thinking based on inquiry. The field of critical thinking, as manifested in the Informal Logic movement, developed primarily as a response to the inadequacies of formalism to represent actual argumentative practice and to provide useful argumentative skills to students. Because of this, the primary focus of the field has been on informal arguments rather than formal reasoning. Yet the formalist history of the field is still evident (...) in its emphasis, with respect to both theory and pedagogy, on the structure and evaluation of individual, de-contextualized arguments. It is our view that such a view of critical thinking is excessively narrow and limited, failing to provide an understanding of argumentation as largely a matter of comparative evaluation of a variety of contending positions and arguments with the goal of reaching a reasoned judgment on an issue. As a consequence, traditional critical thinking instruction is problematic in failing to provide the reasoning skills that students need in order to accomplish this goal. Instead, the goal of critical thinking instruction has been seen largely as a defensive one: of learning to not fall prey to invalid, inadequate, or fallacious arguments. (shrink)

This paper contributes to an on-going exchange in political theory on the normative legitimacy of expert bodies. It focuses on epistemic worries about the expertisation of politics, and uses the Nordic system of advisory commissions as an empirical case. Epistemic concerns are often underplayed by those who defend an increasing role of experts in policy-making, while those who have epistemic worries often tend to overstate them and debunk expertise. We present ten epistemic worries, of which some are of an epistemological (...) nature, while others are related to failures and biases. These worries must not be overstated, but no doubt point to real problems which have to be handled through the design of expert bodies and institutions of science advice. We introduce three groups of mechanisms that are likely to contribute to remedying the problems of expertise and discuss what they imply for the design of a system of public advisory commissions.

The appeal to expert opinion is an argument form that uses the verdict of an expert to support a position or hypothesis. A previous scheme-based treatment of the argument form is formalized within a Bayesian network that is able to capture the critical aspects of the argument form, including the central considerations of the expert's expertise and trustworthiness. We propose this as an appropriate normative framework for the argument form, enabling the development and testing of quantitative predictions as to how (...) people evaluate this argument, suggesting that such an approach might be beneficial to argumentation research generally. We subsequently present two experiments as an example of the potential for future research in this vein, demonstrating that participants' quantitative ratings of the convincingness of a proposition that has been supported with an appeal to expert opinion were broadly consistent with the predictions of the Bayesian model.

In his influential work on critical argumentation, Douglas Walton explains how to judge whether an argumentum ad verecundiam is fallacious or legitimate. He provides six critical questions and a number of ancillary sub-questions to guide the identification of reasonable appeals to authority. While it is common for informal logicians to acknowledge the role of bias in sampling procedures and hypothesis confirmation , there is a conspicuous lack of discourse on the effect of identity prejudice on judgments of authority, even though (...) this is a well-documented factor in attributing credibility, expertise, trustworthiness, and professional competence to oppressed groups. This could result in faulty judgments of ad verecundiam fallacy. Focusing on gender bias, I review recent works in feminist epistemology—particularly those of Miranda Fricker and Helen Longino —to develop three gender-based critical questions to supplement Walton’s original list of six. This addition will help us to identify erroneous dismissals of appeals to authority based on epistemic injustice and epistemic irresponsibility on the part of the speaker or knowledge community. This project promotes the overlapping aims of feminist epistemology and informal logic. (shrink)

Different approaches to expertise and argumentation are discussed. After introducing the problem of expertise and its present day significance in a historical context, various connections with the study of arguments are highlighted. The need for and potential of argumentation analysis to contribute to existing research in social epistemology, science studies, and cognitive science, is discussed, touching on the problems of reasoning and argumentation, embodiment, tacit knowledge, expert context versus public context, expert disagreement, persuasion versus justification, and argument analysis as meta-expertise. (...) As the arguments used by experts constitute a boundary object, we presume that a dialogue format is suitable to address central problems of the special issue “Rethinking Arguments from Experts”.

In this paper, I argue that ad hominem arguments are not always fallacious. More explicitly, in certain cases of practical reasoning, the circumstances of a person are relevant to whether or not the conclusion should be accepted. This occurs, I suggest, when a person gives advice to others or prescribes certain courses of action but fails to follow her own advice or act in accordance with her own prescriptions. This is not an instance of a fallacious tu quoque provided that (...) such circumstantial ad hominem arguments are construed as rebuttals to appeals (administrative) authority (of expertise), or so I argue.

In this article, I further analyze the notion of the effectiveness of argumentative strategies, introduced in Jovičić, 2001. The most relevant achievements of the theories of reasonable discussion and the theories of persuasion are called to mind with the aim of explaining the mechanism of the argumentative effectiveness. As a result, a procedure for evaluating the effectiveness of argumentative strategies is suggested.

In academic contexts the appeal to authority is a quite common but seldom tested argument, either because we accept the authority without questioning it, or because we look for alternative experts or reasons to support a different point of view. But, by putting ourselves side by side an already accepted authority, we often rhetorically manoeuvre to displace the burden of the proof to avoid the fear to present our opinions and to allow face saving.

As appeals to expert authority shift from “fallacies” to “argument schemes,” argumentation theorists are called on to provide critical questions for assessing them. I argue that current treatments focus too heavily on assessing expertise, and not enough on judging trustworthiness. I propose instead a norma-tive pragmatic account of the rational force of the appeal to expert authority, one that emphasizes the ex-pert's actions in constructing his/her own legitimate trustworthiness.

Trust is a natural mechanism by which an autonomous party, an agent, can deal with the inherent uncertainty regarding the behaviours of other parties and the uncertainty in the information it shares with those parties. Trust is thus crucial in any decentralised system. This paper builds on recent efforts to use argumentation to reason about trust. Specifically, a set of schemes is provided, and abstract patterns of reasoning that apply in multiple situations geared towards trust. Schemes are described in which (...) one agent, A, can establish arguments for trusting another agent, B, directly, as well as schemes that A can use to construct arguments for trusting C, where C is trusted by B. For both sets of schemes, a set of critical questions is offered that identify the situations in which these schemes can fail. (shrink)

How does a parent get a child to do something? And, indeed, how might the child avoid complying or seem to comply without actually having done so? This article uses conversation analysis to identify the interactionally preferred and dispreferred response to directives. It then focuses on one alternative response option that has both verbal and embodied elements. The first part involves an embodied display of incipient compliance. That is, actions that are preparatory steps towards compliance and signal that it may (...) be forthcoming, but which do not in themselves constitute compliance. Incipient compliance creates sequential space for a verbal turn that reformulates the ongoing action as autonomous, self-motivated behaviour on the recipient’s part, rather than subject to the will of the directive speaker. This enables the recipient to maintain autonomy over their own conduct without provoking the conflict or repeat directives associated with outright resistance. (shrink)

In this paper, we will explore two initiatives that focus on the importance of employing logical theories in educating people how to think and reason properly, one in Poland: The Lvov-Warsaw School; the other in North America: The Informal Logic Initiative. These two movements differ in the logical means and skills that they focus on. However, we believe that they share a common purpose: to educate students in logic and reasoning (logical education conceived as a process) so that they may (...) be able to apply their skills to analyze the issues in their society (logical culture as a result of logical education). The aim of the paper is to justify this claim by exploring research objectives and products that are common to both movements. (shrink)
