35The CDF collaboration and argumentation theory: The role of process in objective knowledgePerspectives on Science 16 (1): 1-25. 2008.: For philosophers of science interested in elucidating the social character of science, an important question concerns the manner in which and degree to which the objectivity of scientific knowledge is socially constituted. We address this broad question by focusing specifically on philosophical theories of evidence. To get at the social character of evidence, we take an interdisciplinary approach informed by categories from argumentation studies. We then test these categories by exploring thei…Read more

20Natural Laws in Scientific Practice (review)Review of Metaphysics 56 (2): 435-436. 2002.One might view the literature on laws of nature as dividing into two camps: the “metaphysical” advocates of laws as objective realities beyond any actual regularities, and the “antimetaphysical” skeptics. Hard-liners in both camps will find much to disagree with in Marc Lange’s Natural Laws in Scientific Practice. I mean that as a compliment to Lange’s work.

81Securing the Empirical Value of Measurement ResultsBritish Journal for the Philosophy of Science 71 (1): 87-113. 2020.Reports of quantitative experimental results often distinguish between the statistical uncertainty and the systematic uncertainty that characterize measurement outcomes. This article discusses the practice of estimating systematic uncertainty in high-energy physics. The estimation of systematic uncertainty in HEP should be understood as a minimal form of quantitative robustness analysis. The secure evidence framework is used to explain the epistemic significance of robustness analysis. However, …Read more

Over the Top: Experiment and the Testing of Hypotheses in the Search for the Top QuarkDissertation, The Johns Hopkins University. 1998.This study presents a historical account of experiments, performed by the Collider Detector at Fermilab collaboration, which led to the discovery of the top quark, and a discussion of philosophical issues raised by that episode. ;The historical discussion is based on published and unpublished documents and oral history interviews, and is presented in two parts: First, the formation of the collaboration and construction of the detector are described. The activities of the collaborators during the…Read more

461Error-statistical elimination of alternative hypothesesSynthese 163 (3). 2008.I consider the error-statistical account as both a theory of evidence and as a theory of inference. I seek to show how inferences regarding the truth of hypotheses can be upheld by avoiding a certain kind of alternative hypothesis problem. In addition to the testing of assumptions behind the experimental model, I discuss the role of judgments of implausibility. A benefit of my analysis is that it reveals a continuity in the application of error-statistical assessment to low-level empirical hypot…Read more

151I contrast two modes of error-elimination relevant to evaluating evidence in accounts that emphasize frequentist reliability. The contrast corresponds to that between the use of of a reliable inference procedure and the critical scrutiny of a procedure with regard to its reliability, in light of what is and is not known about the setting in which the procedure is used. I propose a notion of security as a category of evidential assessment for the latter. In statistical settings, robustness theory…Read more

51Evidence claims depend on fallible assumptions. Three strategies for making true evidence claims in spite of this fallibility are strengthening the support for those assumptions, weakening conclusions, and using multiple independent tests to produce robust evidence. Reliability itself, understood in frequentist terms, does not explain the usefulness of all three strategies; robustness, in particular, sometimes functions in a way that is not well-characterized in terms of reliability. I argue tha…Read more

224This paper examines probabilistic versions of the fine-tuning argument for design (FTA), with an emphasis on the interpretation of the probability statements involved in such arguments. Three categories of probability are considered: physical, epistemic, and logical. Of the three possibilities, I argue that only logical probability could possibly support a cogent probabilistic FTA. However, within that framework, the premises of the argument require a level of justification that has not been met…Read more

53Golden events and statistics: What's wrong with Galison's image/logic distinction?Perspectives on Science 7 (2): 196-230. 1999.: Peter Galison has recently claimed that twentieth-century microphysics has been pursued by two distinct experimental traditions--the image tradition and the logic tradition--that have only recently merged into a hybrid tradition. According to Galison, the two traditions employ fundamentally different forms of experimental argument, with the logic tradition using statistical arguments, while the image tradition strives for non-statistical demonstrations based on compelling ("golden") single eve…Read more

38This paper analyzes Deborah Mayo's error-statistical (ES) account of scientific evidence in order to clarify the kinds of "material postulates" it requires and to explain how those assumptions function. A secondary aim is to explain and illustrate the importance of the security of an inference. After finding that, on the most straightforward reading of the ES account, it does not succeed in its stated aims, two remedies are considered: either relativize evidence claims or introduce stronger assu…Read more

57: Evidence claims depend on fallible assumptions. This paper discusses inferential robustness as a strategy for justifying evidence claims in spite of this fallibility. I argue that robustness can be understood as a means of establishing the partial security of evidence claims. An evidence claim is secure relative to an epistemic situation if it remains true in all scenarios that are epistemically possible relative to that epistemic situation.

36Novelty, severity, and history in the testing of hypotheses: The case of the top quarkPhilosophy of Science 63 (3): 255. 1996.It is sometimes held that facts confirm a hypothesis only if they were not used in the construction of that hypothesis. This requirement of "use novelty" introduces a historical aspect into the assessment of evidence claims. I examine a methodological principle invoked by physicists in the experimental search for the top quark that bears a striking resemblance to this view. However, this principle is better understood, both historically and philosophically, in terms of the need to conduct a seve…Read more

29The Evidence for the Top Quark: Objectivity and Bias in Collaborative ExperimentationCambridge University Press. 2004.The Evidence for the Top Quark offers both a historical and philosophical perspective on an important recent discovery in particle physics: evidence for the elementary particle known as the top quark. Drawing on published reports, oral histories, and internal documents from the large collaboration that performed the experiment, Kent Staley explores in detail the controversies and politics that surrounded this major scientific result. At the same time the book seeks to defend an objective theory …Read more

72Pragmatic warrant for frequentist statistical practice: the case of high energy physicsSynthese 194 (2). 2017.Amidst long-running debates within the field, high energy physics has adopted a statistical methodology that primarily employs standard frequentist techniques such as significance testing and confidence interval estimation, but incorporates Bayesian methods for limited purposes. The discovery of the Higgs boson has drawn increased attention to the statistical methods employed within HEP. Here I argue that the warrant for the practice in HEP of relying primarily on frequentist methods can best be…Read more

130Internalist and externalist aspects of justification in scientific inquirySynthese 182 (3): 475-492. 2011.While epistemic justification is a central concern for both contemporary epistemology and philosophy of science, debates in contemporary epistemology about the nature of epistemic justification have not been discussed extensively by philosophers of science. As a step toward a coherent account of scientific justification that is informed by, and sheds light on, justificatory practices in the sciences, this paper examines one of these debates—the internalist-externalist debate—from the perspective…Read more
