Explanations of former South African President Thabo Mbeki’s public and private views on the aetiology of the HIV/AIDS epidemic in the country remain partial at best without the recognition that the latter presuppose and imply a postmodernist/postcolonialist philosophy of science that erases the line separating the political from the scientific. Evidence from Mbeki’s public speeches, interviews, and private and anonymous writings suggests that it was postmodernist/postcolonialist theory that inspired him to doubt the “Western” scientific consensus on HIV/AIDS and to implement (...) a public health policy that dragged its feet on full roll-out of antiretroviral therapy, causing thousands of avoidable deaths. A weak reductio ad absurdum allows us to conclude from this premise that postmodernist/postcolonial critique of “Western” science ought to be shunned. A comparative argument from consequences further suggests that in a situation where a misguided health policy has lead to a humanitarian catastrophe, and where postmodernist/postcolonialist critique of science can and has been used to justify this policy, an alternative theory ought to be preferred on which such justification would not be possible. The paper closes with a call for a non-relativist alternative to postmodernist/postcolonialist philosophy of science, and evaluates the potential of recent developments in ‘Studies of Expertise” to yield such.

This paper elaborates on the link between different types and degrees of experience that can be gone through within a form of life or collectivity—the so-called levels of immersion—and the development of distinct types of tacit knowledge and expertise. The framework is then probed empirically and theoretically. In the first case, its ‘predictions’ are compared with the accounts of novices who have gone through different ‘learning opportunities’ during a pre-operational training programme for running a huge nickel industrial plant in Brazil. (...) These are also analysed vis-à-vis the experience of an expert who has designed and experienced the outcomes of two pre-operational training sessions in the nickel industry before developing and managing the one discussed here. Theoretically, the framework is used to pinpoint exactly what interactional experts who have developed their expertise through linguistic socialisation alone are able to do as well as to analyse the case of technical connoisseurs. The results indicate that the proposed framework is useful. It supports the design and improvement of training programmes for the development of tacit knowledge while at the same time bringing about a refined analysis of claims concerning the abilities of types of experts and expertise.

The phrase ‘trading zone’ is often used to denote any kind of interdisciplinary partnership in which two or more perspectives are combined and a new, shared language develops. In this paper we distinguish between different types of trading zone by asking whether the collaboration is co-operative or coerced and whether the end-state is a heterogeneous or homogeneous culture. In so doing, we find that the voluntary development of a new language community—what we call an inter-language trading zone—represents only one of (...) four possible configurations. In developing this argument we show how different modes of collaboration result in different kinds of trading zone, how different kinds of trading zone may be ‘nested’ inside each other and discuss how a single collaboration might move between different kinds of trading zone over time. One implication of our analysis is that interactional expertise is a central component of at least one class of trading zone.Keywords: Trading zones; Interactional expertise; Interdisciplinarity; Creole.

Abstract: This essay critically examines whether there are ethical dimensions to the way that expertise, knowledge claims, and expressions of skepticism intersect on technical matters that influence public policy, especially during times of crisis. It compares two different perspectives on the matter: a philosophical outlook rooted in discourse and virtue ethics and a sociological outlook rooted in the so-called third-wave approach to science studies. The comparison occurs through metaphilosophical analysis and applied claims that clarify how the disciplinary orientations appear to (...) lead to different judgments about matters related to Robert Paarlberg's condemnation of activists who advise African politicians to ban genetically modified food.

We argue that the way in which the concept of expertise is understood and invoked has prevented progress in the debate as to whether moral philosophers can be said to be ‘moral experts’. We offer an account of expertise that draws on the role of tacit knowledge in order to provide a basis upon which the debate can progress. Our analysis consists of three parts. In the first part we highlight two specific problems in the way that the concept of (...) expertise has been invoked in the moral expertise debate, namely the understanding of expertise as an exclusive concept and the conflation of expertise with the idea of ‘authority’. In the second part we suggest an alternative way of approaching the concept of expertise. This is based on Collins and Evans’ sociological theory of expertises. This theory provides a valuable analytical framework for thinking about claims to expertise and for drawing the kinds of distinctions which allow for different kinds of moral expertises and competencies. In the final part, we show how the application of this theory helps to avoid some of the problematic conclusions which theorists have arrived at to date and provides a common platform for debate. Ultimately, it permits the argument to be made that moral philosophers could be considered specialist members of an expert community of moral decision-makers. (shrink)

Work in Argumentation Studies (AS) and Studies in Expertise and Experience (SEE) has been proceeding on converging trajectories, moving from resistance to expert authority to a cautious acceptance of its legitimacy. The two projects are therefore also converging on the need to account for how, in the course of complex and confused civic deliberations, nonexpert citizens can figure out which statements from purported experts deserve their trust. Both projects recognize that nonexperts cannot assess expertise directly; instead, the nonexpert must judge (...) whether to trust the expert. But how is this social judgment accomplished? A normative pragmatic approach from AS can complement and extend the work from SEE on this question, showing that the expert’s putting forward of his view and “bonding” it with his reputation for expertise works to force or “blackmail” his audience of citizens into heeding what he says. Appeals to authority thus produce the visibility and accountability we want for expert views in civic deliberations. (shrink)

Fringe science has been an important topic since the start of the revolution in the social studies of science that occurred in the early 1970s. The revolution was what Collins and Evans refer to as the "second wave of science studies," while this paper is best thought of as an exercise in "third wave science studies." The first wave was that period which reached its apogee in the aftermath of the Second World War when science was seen as unquestionably the (...) pre-eminent form of knowledge-making, and the role of philosophy and sociology was to understand how it was so and how societies could be arranged to nurture it best; the second wave was "social constructionism" which became folded into post-modernism in...

The outputs of economic forecasting—predictions for national economic indicators such as GDP, unemployment rates and inflation—are all highly visible. The production of these forecasts is a much more private affair, however, typically being thought of as the work of individual forecasters or forecast teams using their economic model to produce a forecast that is then made public. This conception over-emphasises the individual and the technical whilst silencing the broader social context through which economic forecasters develop the expertise that is essential (...) for the credibility of their predictions. In particular, economic forecasts are given meaning and fine-tuned through the social and institutional networks that give forecasters access to the expertise of a heterogeneous mix of academics, policy-makers and business people. Within these broader groups, individual forecasters often create private forecast ‘clubs’, where subscribers have privileged access to the expertise of the economist, but where the forecasters also have privileged access to their clients’ own expert knowledge. In examining these aspects of the forecasters’ work I show that the visible and audible activities of modelling and forecasting are made possible and plausible by virtue of the modeller’s invisible interaction with a wider network.Keywords: Expertise; Economic forecasting; Periodic table of expertise; Judgement.

The continental drift controversy has been deeply analysed in terms of rationalist notions, which seem to find there a unique topic to describe the weight of evidence for reaching consensus. In that sense, many authors suggest that Alfred Wegener’s theory of the original supercontinent Pangea and the subsequent continental displacements finally reached a consensus when irrefutable evidence became available. Therefore, rationalist approaches suggest that evidence can be enough by itself to close scientific controversies. In this article I analyse continental drift (...) debates from a different perspective which is based on styles of thought. I’ll argue that continental drift debate took much longer than it was usually recognized with two styles of thought coexisting for hundreds of years. These were fixism and mobilism and they were always confronting their own evidence and interpretations and functioning as general frameworks for the acceptability of a specific theory. Therefore, this text aims to bring much broader sociological elements than usually involved in the analysis of the continental drift theory. (shrink)
