  1. Robustness, Discordance, and Relevance.Jacob Stegenga - 2009 - Philosophy of Science 76 (5):650-661.
    Robustness is a common platitude: hypotheses are better supported with evidence generated by multiple techniques that rely on different background assumptions. Robustness has been put to numerous epistemic tasks, including the demarcation of artifacts from real entities, countering the “experimenter’s regress,” and resolving evidential discordance. Despite the frequency of appeals to robustness, the notion itself has received scant critique. Arguments based on robustness can give incorrect conclusions. More worrying is that although robustness may be valuable (...)

  2. Robustness Analysis as Explanatory Reasoning.Jonah N. Schupbach - 2016 - British Journal for the Philosophy of Science:axw008.
    When scientists seek further confirmation of their results, they often attempt to duplicate the results using diverse means. To the extent that they are successful in doing so, their results are said to be robust. This paper investigates the logic of such "robustness analysis" [RA]. The most important and challenging question an account of RA can answer is what sense of evidential diversity is involved in RAs. I argue that prevailing formal explications of such diversity are unsatisfactory. I propose (...)

  3. Robustness and Independent Evidence.Jacob Stegenga & Tarun Menon - 2017 - Philosophy of Science 84 (3):414-435.
    Robustness arguments hold that hypotheses are more likely to be true when they are confirmed by diverse kinds of evidence. Robustness arguments require the confirming evidence to be independent. We identify two kinds of independence appealed to in robustness arguments: ontic independence —when the multiple lines of evidence depend on different materials, assumptions, or theories—and probabilistic independence. Many assume that OI is sufficient for a robustness argument to be warranted. However, we argue that, as typically construed, (...)

  4. Robustness and Reality.Markus Eronen - 2015 - Synthese 192 (12):3961-3977.
    Robustness is often presented as a guideline for distinguishing the true or real from mere appearances or artifacts. Most of recent discussions of robustness have focused on the kind of derivational robustness analysis introduced by Levins, while the related but distinct idea of robustness as multiple accessibility, defended by Wimsatt, has received less attention. In this paper, I argue that the latter kind of robustness, when properly understood, can provide justification for ontological commitments. The idea (...)

  5. Robust Virtue Epistemology As Anti‐Luck Epistemology: A New Solution.J. Adam Carter - 2016 - Pacific Philosophical Quarterly 97 (1):140-155.
    Robust Virtue Epistemology maintains that knowledge is achieved just when an agent gets to the truth through, or because of, the manifestation of intellectual virtue or ability. A notorious objection to the view is that the satisfaction of the virtue condition will be insufficient to ensure the safety of the target belief; that is, RVE is no anti-luck epistemology. Some of the most promising recent attempts to get around this problem are considered and shown to ultimately fail. Finally, a new (...)

  6. Model Robustness as a Confirmatory Virtue: The Case of Climate Science.Elisabeth A. Lloyd - 2015 - Studies in History and Philosophy of Science Part A 49:58-68.
    I propose a distinct type of robustness, which I suggest can support a confirmatory role in scientific reasoning, contrary to the usual philosophical claims. In model robustness, repeated production of the empirically successful model prediction or retrodiction against a background of independentlysupported and varying model constructions, within a group of models containing a shared causal factor, may suggest how confident we can be in the causal factor and predictions/retrodictions, especially once supported by a variety of evidence framework. I (...)

    In robustness analysis, hypotheses are supported to the extent that a result proves robust, and a result is robust to the extent that we detect it in diverse ways. But what precise sense of diversity is at work here? In this paper, I show that the formal explications of evidential diversity most often appealed to in work on robustness – which all draw in one way or another on probabilistic independence – fail to shed light on the notion (...)

  8. On Robust Discursive Equality.Thomas M. Besch - 2019 - Dialogue 58 (3):1-26.
    This paper explores the idea of robust discursive equality on which respect-based conceptions of justificatory reciprocity often draw. I distinguish between formal and substantive discursive equality and argue that if justificatory reciprocity requires that people be accorded formally equal discursive standing, robust discursive equality should not be construed as requiring standing that is equal substantively, or in terms of its discursive purchase. Still, robust discursive equality is purchase sensitive: it does not obtain when discursive standing is impermissibly unequal in purchase. (...)

  9. Abductively Robust Inference.Finnur Dellsén - 2017 - Analysis 77 (1):20-29.
    Inference to the Best Explanation (IBE) is widely criticized for being an unreliable form of ampliative inference – partly because the explanatory hypotheses we have considered at a given time may all be false, and partly because there is an asymmetry between the comparative judgment on which an IBE is based and the absolute verdict that IBE is meant to license. In this paper, I present a further reason to doubt the epistemic merits of IBE and argue that it motivates (...)

  10. Robust Evidence and Secure Evidence Claims.Kent W. Staley - 2004 - Philosophy of Science 71 (4):467-488.
    Many philosophers have claimed that evidence for a theory is better when multiple independent tests yield the same result, i.e., when experimental results are robust. Little has been said about the grounds on which such a claim rests, however. The present essay presents an analysis of the evidential value of robustness that rests on the fallibility of assumptions about the reliability of testing procedures and a distinction between the strength of evidence and the security of an evidence claim. (...) can enhance the security of an evidence claim either by providing what I call second-order evidence, or by providing back-up evidence for a hypothesis. (shrink)

    I consider some hitherto unexplored examples of teleological language in the sciences. In explicating these examples, I aim to show (a) that such language is not the sole preserve of the biological sciences, and (b) that not all such talk is reducible to the ascription of functions. In chemistry and biochemistry, scientists explaining molecular rearrangements and protein folding talk informally of molecules rearranging “in order to” maximize stability. Evolutionary biologists, meanwhile, often speak of traits evolving “in order to” optimize some (...)

    Although scientific realism is the default position in the life sciences, philosophical accounts of realism are geared towards physics and run into trouble when applied to fields such as biology or neuroscience. In this paper, I formulate a new robustness-based version of entity realism, and show that it provides a plausible account of realism for the life sciences that is also continuous with scientific practice. It is based on the idea that if there are several independent ways of measuring, (...)

    Recent philosophical attention to climate models has highlighted their weaknesses and uncertainties. Here I address the ways that models gain support through observational data. I review examples of model fit, variety of evidence, and independent support for aspects of the models, contrasting my analysis with that of other philosophers. I also investigate model robustness, which often emerges when comparing climate models simulating the same time period or set of conditions. Starting from Michael Weisberg’s analysis of robustness, I conclude (...)

  14. A Robust Defence of the Doctrine of Doing and Allowing.Xiaofei Liu - 2012 - Utilitas 24 (1):63-81.
    Philosophers debate over the truth of the Doctrine of Doing and Allowing, the thesis that there is a morally significant difference between doing harm and merely allowing harm to happen. Deontologists tend to accept this doctrine, whereas consequentialists tend to reject it. A robust defence of this doctrine would require a conceptual distinction between doing and allowing that both matches our ordinary use of the concepts in a wide range of cases and enables a justification for the alleged moral difference.

  16. Philosophical Intuitions Are Surprisingly Robust Across Demographic Differences.Joshua Knobe - 2019 - Epistemology and Philosophy of Science 56 (2):29-36.
    Within the existing metaphilosophical literature on experimental philosophy, a great deal of attention has been devoted to the claim that there are large differences in philosophical intuitions between people of different demographic groups. Some philosophers argue that this claim has important metaphilosophical implications; others argue that it does not. However, the actual empirical work within experimental philosophy seems to point to a very different sort of metaphilosophical question. Specifically, what the actual empirical work suggests is that intuitions are surprisingly robust (...)

    Frankfurt-style cases purport to show that an agent can be morally responsible for an action despite not having any alternatives. Some critics have responded by highlighting various alternatives that remain in the cases presented, while Frankfurtians have objected that such alternatives are typically not capable of grounding responsibility. In this essay I address the recent suggestion by Seth Shabo that only alternatives associated with the ‘up to us’ locution ground moral responsibility. I distinguish a number of kinds of ability, suggest (...)

    Certain relationships generate associative duties that exhibit robustness across change. It seems insufficient for friendship, for example, if I am only disposed to fulfil duties of friendship towards you as things stand here and now. However, robustness is not required across all variations. Were you to become monstrously cruel towards me, we might expect that my duties of friendship towards you would not be robust across that kind of change. The question then is this: is there any principled (...)

  20. Radical Skepticism, Closure, and Robust Knowledge.J. Adam Carter - 2011 - Journal of Philosophical Research 36:115-133.
    The Neo-Moorean response to the radical skeptical challenge boldly maintains that we can know we’re not the victims of radical skeptical hypotheses; accordingly, our everyday knowledge that would otherwise be threatened by our inability to rule out such hypotheses stands unthreatened. Given the leverage such an approach has against the skeptic from the very start, the Neo-Moorean line is an especially popular one; as we shall see, though, it faces several commonly overlooked problems. An initial problem is that this particular (...)

    Taking Morality Seriously is David Enoch’s book-length defense of meta-ethical and meta-normative non-naturalist realism. After describing Enoch’s position and outlining the argumentative strategy of the book, we engage in a critical discussion of what we take to be particularly problematic central passages. We focus on Enoch’s two original positive arguments for non-naturalist realism, one argument building on first order moral implications of different meta-ethical positions, the other attending to the rational commitment to normative facts inherent in practical deliberation. We also (...)

    When a technique purports to provide information that is not available to the unaided senses, it is natural to think that the only way to validate that technique is by appealing to a theory of the processes that lead from the object of study to the raw data. In fact, scientists have a variety of strategies for validating their techniques. Those strategies can yield multiple independent arguments that support the validity of the technique. Thus, it is possible to produce a (...)

  25. Pereboom’s Robust Non-Reductive Physicalism.Andrew Melnyk - 2014 - Erkenntnis 79 (5):1191-1207.
    Derk Pereboom has recently elaborated a formulation of non-reductive physicalism in which supervenience does not play the central role and realization plays no role at all; he calls his formulation “robust non-reductive physicalism”. This paper argues that for several reasons robust non-reductive physicalism is inadequate as a formulation of physicalism: it can only rule out fundamental laws of physical-to-mental emergence by stipulating that there are no such laws; it fails to entail the supervenience of the mental on the physical; it (...)

    A small but growing number of studies have aimed to understand, assess and reduce existential risks, or risks that threaten the continued existence of mankind. However, most attention has been focused on known and tangible risks. This paper proposes a heuristic for reducing the risk of black swan extinction events. These events are, as the name suggests, stochastic and unforeseen when they happen. Decision theory based on a fixed model of possible outcomes cannot properly deal with this kind of event. (...)

    In biomedical measurement, biomarkers are used to achieve reliable prediction of, and useful causal information about patient outcomes while minimizing complexity of measurement, resources, and invasiveness. A biomarker is an assayable metric that discloses the status of a biological process of interest, be it normative, pathophysiological, or in response to intervention. The greatest utility from biomarkers comes from their ability to help clinicians (and researchers) make and evaluate clinical decisions. In this paper we discuss a specific methodological use of clinical (...)

  29. Counterfactually Robust Inferences, Modally Ruled Out Inferences, and Semantic Holism.Pietro Salis - 2016 - AL-Mukhatabat (16):111-35.
    It is often argued that inferential role semantics (IRS) entails semantic holism as long as theorists fail to answer the question about which inferences, among the many, are meaning-constitutive. Since analyticity, as truth in virtue of meaning, is a widely dismissed notion in indicating which inferences determine meaning, it seems that holism follows. Semantic holism is often understood as facing problems with the stability of content and many usual explanations of communication. Thus, we should choose between giving up IRS, to (...)

    In this paper we make a simple theoretical point using a practical issue as an example. The simple theoretical point is that robustness is not 'all or nothing': in asking whether a system is robust one has to ask 'robust with respect to what property?' and 'robust over what set of changes in the system?' The practical issue used to illustrate the point is an examination of degrees of linkage between sub-networks and a pointed contrast in robustness and (...)

    Deliberative democracy aspires to secure political liberty by making citizens the authors of their laws. But how can it do this in the face of deep disagreement, not to mention imperfect knowledge and limited altruism? Deliberative democracy can secure political liberty by affording each citizen an equal position as a co-author of public laws and norms. Moreover, fundamental deliberative democracy—in which institutional design is ultimately accountable to public deliberation but not necessarily subject to its direct control—does not strain knowledge or (...)

    According to some, free will requires alternative possibilities. But not any old alternative possibility will do. Sometimes, being able to bring about an alternative does not bestow any control on an agent. In order to bestow control, and so be directly relevant qua alternative to grounding the agent's moral responsibility, alternatives need to be robust. Here, I investigate the nature of robust alternatives. I argue that Derk Pereboom's latest robustness criterion is too strong, and I suggest a different criterion (...)

    Robust Justification.Jonathan Matheson - forthcoming - In Scott Stapleford & Kevin McCain (eds.), Epistemic Duties: New Arguments, New Angles. Routledge.
    According to evidentialism, a subject is justified in believing a proposition at a time, just in case their evidence on balance supports that proposition at that time. Evidentialist justification is thus a property of fit – fitting the subject’s evidence. However, evidentialism does not evaluate the subject’s evidence beyond this relation of fit. For instance, evidentialism ignores whether the subject was responsible or negligent in their inquiry. A number of objections have been raised to evidentialism involving cases of irresponsible inquiry (...)

    Robustness to Fundamental Uncertainty in AGI Alignment.I. I. I. G. Gordon Worley - manuscript
    The AGI alignment problem has a bimodal distribution of outcomes with most outcomes clustering around the poles of total success and existential, catastrophic failure. Consequently, attempts to solve AGI alignment should, all else equal, prefer false negatives (ignoring research programs that would have been successful) to false positives (pursuing research programs that will unexpectedly fail). Thus, we propose adopting a policy of responding to points of metaphysical and practical uncertainty associated with the alignment problem by limiting and choosing necessary assumptions (...)

    Data access control is a challenging issue in public cloud storage systems. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has been adopted as a promising technique to provide flexible, fine-grained and secure data access control for cloud storage with honest-but- curious cloud servers.

    Mark Pennington’s Robust Political Economy is a systematic exposition of a framework for analyzing institutional performance. The Robust Political Economy framework evaluates institutions according to their ability to solve knowledge and incentive problems. On grounds of robustness, Pennington combines insights from Austrian market-process theory and public-choice theory to defend classical liberalism from several compelling critiques. These include theories of market failure in economics; communitarian, deliberative-democratic, and liberal-egalitarian theories of justice; and concerns with social capital, domestic and international poverty, and (...)

    To study climate change, scientists employ computer models, which approximate target systems with various levels of skill. Given the imperfection of climate models, how do scientists use simulations to generate knowledge about the causes of observed climate change? Addressing a similar question in the context of biological modelling, Levins (1966) proposed an account grounded in robustness analysis. Recent philosophical discussions dispute the confirmatory power of robustness, raising the question of how the results of computer modelling studies contribute to (...)

    Does Moral Discourse Require Robust Truth?Fritz J. McDonald - 2009 - Logos Architekton 3.
    It has been argued by several philosophers that a deflationary conception of truth, unlike more robust conceptions of truth, cannot properly account for the nature of moral discourse. This is due to what I will call the “quick route problem”: There is a quick route from any deflationary theory of truth and certain obvious features of moral practice to the attribution of truth to moral utterances. The standard responses to the quick route problem are either to urge accepting a conception (...)
