A background assumption of this paper is that the repertoire of inference schemes available to humanity is not fixed, but subject to change as new schemes are invented or refined and as old ones are obsolesced or abandoned. This is particularly visible in areas like health and environmental sciences, where enormous societal investment has been made in finding ways to reach more dependable conclusions. Computational modeling of argumentation, at least for the discourse in expert fields, will require the possibility of modeling change in a stock of schemes that may be applied to generate conclusions from data. We examine Randomized Clinical Trial, an inference scheme established within medical science in the mid-20th Century, and show that its successful defense by means of practical reasoning allowed for its black-boxing as an inference scheme that generates (and warrants belief in) conclusions about the effects of medical treatments. Modeling the use of a scheme is well-understood; here we focus on modeling how the scheme comes to be established so that it is available for use.

Background Providing understandable information to patients is necessary to achieve the aims of the Informed Consent process: respecting and promoting patients’ autonomy and protecting patients from harm. In recent decades, new, primarily digital technologies have been used to apply and test innovative formats of Informed Consent. We conducted a systematic review to explore the impact of using digital tools for Informed Consent in both clinical research and in clinical practice. Understanding, satisfaction and participation were compared for digital tools versus the non-digital Informed Consent process. Methods We searched for studies on available electronic databases, including Pubmed, EMBASE, and Cochrane. Studies were identified using specific Mesh-terms/keywords. We included studies, published from January 2012 to October 2020, that focused on the use of digital Informed Consent tools for clinical research, or clinical procedures. Digital interventions were defined as interventions that used multimedia or audio–video to provide information to patients. We classified the interventions into 3 different categories: video only, non-interactive multimedia, and interactive multimedia. Results Our search yielded 19,579 publications. After title and abstract screening 100 studies were retained for full-text analysis, of which 73 publications were included. Studies examined interactive multimedia, non-interactive multimedia, and videos, and most studies were conducted on adults. Innovations in consent were tested for clinical/surgical procedures and clinical research. For research IC, 21 outcomes were explored, with a positive effect on at least one of the studied outcomes being observed in 8/12 studies. For clinical/surgical procedures 49 outcomes were explored, and 21/26 studies reported a positive effect on at least one of the studied outcomes. Conclusions Digital technologies for informed consent were not found to negatively affect any of the outcomes, and overall, multimedia tools seem desirable. Multimedia tools indicated a higher impact than videos only. Presence of a researcher may potentially enhance efficacy of different outcomes in research IC processes. Studies were heterogeneous in design, making evaluation of impact challenging. Robust study design including standardization is needed to conclusively assess impact.

Argument is a pervasive feature of human interaction, and in its natural contexts of occurrence, it is organized around the management of disagreement. Since disagreement can occur around any kind of speech act whatsoever, not all arguments involve a claim supported by reasons; many involve standpoints attributed to someone but claimed by no one. And although truth and validity are often at issue in naturally occurring arguments, these do not exhaust the standards to which arguers are held. Arguers hold one another accountable for cooperating in the management of disagreement, infusing argumentation with a natural normativity that exists apart from any theorized appraisal standard applied to the claim-reason relationship. Argumentation’s natural normativity is visible not only in how arguments unfold in interaction but also in how humanity continuously strives to improve its methods of disagreement management.

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.

People often have conflicting values, goals, and beliefs, and these present special challenges for those who seek to influence them. Kauffeld and Innocenti suggest that these situations of conflictedness are opportunities for a speaker to “exhort” the audience to resolve the conflict in favor of their highest principle. Exhortation, in their view, has high-mindedness as a constitutive feature. At Cooper Union, Lincoln exhorted Republicans to face their fear of disunion and steadfastly maintain the evil of slavery—a confirming example for the Kauffeld and Innocenti account. But looking at a broader set of examples, it seems clear that exhortations do not always fit the pattern of appeal to higher principles. Exhortation may occur for any conflictedness the speaker imagines the audience as having, including mundane matters of self-interest. A speaker's attributions of belief, goal, motive, or other cognitive state to an addressee is always rhetorically risky, and these attributions may themselves become a space for disagreement. We can learn from speakers who manage this rhetorical risk well, but also from the much greater number of speakers who do it poorly.

This essay proposes a design perspective on argumentation, intended as complementary to empirical and critical scholarship. In any substantive domain, design can provide insights that differ from those provided by scientific or humanistic perspectives. For argumentation, the key advantage of a design perspective is the recognition that humanity’s natural capacity for reason and reasonableness can be extended through inventions that improve on unaided human intellect. Historically, these inventions have fallen into three broad classes: logical systems, scientific methods, and disputation frameworks. Behind each such invention is a specifiable “design hypothesis”: an idea about how to decrease error or how to increase the quality of outcomes from reasoning. As problems in contemporary argumentation practice become more complex, design thinking rises in relevance and importance. A design research agenda in argumentation would focus on theorizing design innovations and on evaluating design hypotheses.

By offering us a voice that is both at a distance and inside one's own head, the telephone causes interference in thinking and writing. But despite the multiple telephones that echo in and across Jacques Derrida's work, and specifically his writing to and with Hélène Cixous, it is only since Derrida's death that critical interest in the phone has fully emerged, with work by Royle (2006), Prenowitz (2008), Bennington (2013) and Turner (2014) stressing the value of staying on the line. Engaging with Derrida, however, is not simply a matter of picking up the receiver. For the telephone is also, Derrida insists in H.C. for Life (2006), a ‘poetico-technical invention’, that is, the telephone is ‘thought itself’. This paper is about how the telephone ‘thinks’ Derrida, about how it remembers Derrida, and about how it offers us a line for re-imagining his voice. Bound up with the uncanny mechanisms of the telephone, it invites readers to participate in long-distance calling – listening across species, texts and worlds.
