This article aims to defend a novel account of pluralism in economics. First, it argues that what justifies pluralism is its epistemological benefits. Second, it acknowledges that pluralism has limits, and defends reasonable pluralism, or the view that we should only accept those theories and methods that can be justified by their communities with reasons that other communities can accept. Clearly, reasonable pluralism is an ideal, which requires economists of different persuasions to respect certain norms of communication while evaluating each (...) other’s theories. The article ends with a discussion of the conditions under which reasonable communication becomes possible. (shrink)

This paper reviews how research on the demarcation problem has developed, starting from Popper’s criterion of falsifiability and ending with recent naturalistically oriented approaches. The main differences between traditional and contemporary approaches to the problem are explicated in terms of six postulates called the traditional assumptions. It is argued that all of the assumptions can be dismissed without giving up on the demarcation problem and that doing so might benefit further discussions on pseudoscience. Four present-day research movements on evaluating the (...) boundaries of science are introduced: (1) philosophy of pseudoscience, (2) social epistemology of dissent, (3) agnotology, and (4) evaluation of expertise. Researchers working within these areas have abandoned some or all traditional assumptions. (shrink)

I argue that there is a prima facie tension between solutions to the problem of fake news and solutions to the problem presented by various cognitive biases that dispose us to dismiss evidence against our prior beliefs (what might seem to be the driving force behind echo chambers). We can guard against fake news by strengthening belief. But we can exit echo chambers by becoming more sensitive to counterevidence, which seems to require weakening our beliefs. I resolve the tension by (...) arguing against an injunction to weaken belief in the required ways. In particular, there is no injunction to be open-minded in all circumstances toward various counterarguments, even those whose premises seem compelling and in which we can’t expose a flaw. On the contrary, there are circumstances in which you should, in the relevant sense, be closed-minded toward such counterarguments. (shrink)

Feyerabend is infamous for his defense of pluralism, which he extends to every topic he discusses. Disagreement, a by-product of this pluralism, becomes a sign of flourishing critical communities. In Feyerabend’s political works, he extends this pluralism from science to democratic societies and incorporates his earlier work on scientific methodology into a procedure for designing just policy. However, a description and analysis of Feyerabend’s conception of disagreement is lacking. In this paper, I reconstruct and assess Feyerabend’s conception of disagreement, with (...) a particular emphasis on the role of experts, and its role in the formation of science policy. I go on to assess this argument in light of recent literature on manufactured disagreement on politically contentious science policy. I conclude by suggesting some prospects and problems for de-idealizing Feyerabend’s position on disagreement to see whether it may be plausibly implemented. (shrink)

This paper reviews current debates in social epistemology about the relations ‎between ‎knowledge ‎and consensus. These relations are philosophically interesting on their ‎own, but ‎also have ‎practical consequences, as consensus takes an increasingly significant ‎role in ‎informing public ‎decision making. The paper addresses the following questions. ‎When is a ‎consensus attributable to an epistemic community? Under what conditions may ‎we ‎legitimately infer that a consensual view is knowledge-based or otherwise ‎epistemically ‎justified? Should consensus be the aim of scientific inquiry, and (...) if so, what ‎kind of ‎consensus? How should dissent be handled? It is argued that a legitimate inference ‎that a ‎theory is correct from the fact that there is a scientific consensus on it requires taking ‎into ‎consideration both cognitive properties of the theory as well as social properties of ‎the ‎consensus. The last section of the paper reviews computational models of ‎consensus ‎formation.‎. (shrink)

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.

Fake research produces results that are invalid from the start. I take such research to be characterised by three jointly sufficient features. It is severely methodologically defective, and the relevant defects support certain nonepistemic (social, political, economic) interests and objectives, while the relevant objectives typically concern the interference with attempts at political regulation. I deal with two kinds of claimed fake research. One is agnotological ploys in which scientific dissent is created by interested parties from industry or politics in order (...) to support their own partisan goals. Another one is the populist antiscience movement that suspects fake research in the scientific mainstream. I suggest three remedies to reduce or eliminate the impact of fake research: disclosing fallacies, improving the understanding of scientific methods, and distinguishing more clearly between science and politics in political decision-making.

The paper looks at challenges related to the ideas of integration and knowledge systems in extra-academic transdisciplinarity. Philosophers of science are only starting to pay attention to the increasingly common practice of introducing extra-academic perspectives or engaging extra-academic parties in academic knowledge production. So far the rather scant philosophical discussion on the subject has mainly concentrated on the question whether such engagement is beneficial in science or not. Meanwhile, there is quite a large and growing literature on extra-academic TD, mostly (...) authored by non-philosophers, seeking to develop TD research practices. We examine this literature in the light of recent discussions in pluralist philosophies of science. Some philosophical pluralists see the increase of extra-academic collaboration and participation in science as a potentially positive development. However, certain views promoted in the non-philosophical literature on extra-academic TD appear problematic in the light of the pluralistic discussions. For instance, the literature on TD appears to be overly optimistic with regard to integration, and the notion of knowledge systems used in it is problematic. We believe it would be worthwhile for scientific pluralists sympathetic to the aims of TD to look more closely into the complex settings in which extra-academic collaboration and participation happens in actual TD projects, and to offer constructive criticisms, exploiting insights developed within pluralist philosophy of science.

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.
