  1. Getting to know your probabilities: Three ways to frame personal probabilities for decision making.Teddy Seidenfeld - unknown
    Teddy Seidenfeld – CMU An old, wise, and widely held attitude in Statistics is that modest intervention in the design of an experiment followed by simple statistical analysis may yield much more of value than using very sophisticated statistical analysis on a poorly designed existing data set.

  2. Exposing some points of interest about non-exposed points of desirability.Arthur Van Camp & Teddy Seidenfeld - 2022 - International Journal of Approximate Reasoning 144:129-159.
    We study the representation of sets of desirable gambles by sets of probability mass functions. Sets of desirable gambles are a very general uncertainty model, that may be non-Archimedean, and therefore not representable by a set of probability mass functions. Recently, Cozman (2018) has shown that imposing the additional requirement of even convexity on sets of desirable gambles guarantees that they are representable by a set of probability mass functions. Already more that 20 years earlier, Seidenfeld et al. (1995) (...)

  3. A Gentle Approach to Imprecise Probabilities.Gregory Wheeler - 2022 - In Thomas Augustin, Fabio Gagliardi Cozman & Gregory Wheeler (eds.), Reflections on the Foundations of Probability and Statistics: Essays in Honor of Teddy Seidenfeld. Springer. pp. 37-67.
    The field of of imprecise probability has matured, in no small part because of Teddy Seidenfeld’s decades of original scholarship and essential contributions to building and sustaining the ISIPTA community. Although the basic idea behind imprecise probability is (at least) 150 years old, a mature mathematical theory has only taken full form in the last 30 years. Interest in imprecise probability during this period has also grown, but many of the ideas that the mature theory serves can be (...)

  4. Coherent choice functions without Archimedeanity.Enrique Miranda & Arthur Van Camp - 2022 - In Thomas Augustin, Fabio Gagliardi Cozman & Gregory Wheeler (eds.), Reflections on the Foundations of Probability and Statistics: Essays in Honor of Teddy Seidenfeld. Springer.
    We study whether it is possible to generalise Seidenfeld et al.’s representation result for coherent choice functions in terms of sets of probability/utility pairs when we let go of Archimedeanity. We show that the convexity property is necessary but not sufficient for a choice function to be an infimum of a class of lexicographic ones. For the special case of two-dimensional option spaces, we determine the necessary and sufficient conditions by weakening the Archimedean axiom.

    Politics of Dismissal and Death: Tentacle, Necropolitics, and the Political Subject.Teddy Duncan - 2022 - Latin American Literary Review 49 (99):49-53.
    In Rita Indiana’s novel, Tentacle, the future of the Dominic Republic is postulated as bleak and dystopian: a nuclear ecological disaster has nearly ruined the ocean, colorism and racism are pervasive, Haitians are indiscriminately executed due to an unnamed “virus” (Indiana 3), and historical class divisions, as well as wealth inequalities, are maintained. The various issues that Indiana’s future-oriented Dominican Republic is facing emerge from political contingencies: they are the result of clear choices facilitated by the political leaders of the (...)

  6. Expected Utility in 3D.Jean Baccelli - 2022 - In Thomas Augustin, Fabio Gagliardi Cozman & Gregory Wheeler (eds.), Reflections on the Foundations of Probability and Statistics: Essays in Honor of Teddy Seidenfeld. Springer. pp. 187-206.
    Consider a subjective expected utility preference relation. It is usually held that the representations which this relation admits differ only in one respect, namely, the possible scales for the measurement of utility. In this paper, I discuss the fact that there are, metaphorically speaking, two additional dimensions along which infinitely many more admissible representations can be found. The first additional dimension is that of state-dependence. The second—and, in this context, much lesser-known—additional dimension is that of act-dependence. The simplest implication of (...)

  7. Recognizing Exploitation and Rejecting Analogy: An Analysis of the Meat-Commodity.Teddy Duncan Jr - 2024 - Between the Species 27 (1):126-149.
    This paper is a two-part project. First, I reject the analogous relationship between the Holocaust and slaughterhouses (found in the anti-meat novel The Lives of Animals) and cross-species analogical thinking entirely; instead, I opt for modes of analysis that can examine the specific circumstances of animals within slaughterhouses. Secondly, I assert that a socio-economic Marxist analysis is the best prism in which to recognize the suffering of pre-slaughter animals and the causation of their suffering (the ostensibly necessary circulation and production (...)

    Review of Animals, Ethics and Us. [REVIEW]Teddy Duncan - 2022 - Between the Species 7 (1):147-156.
    In Animals, Ethics, and Us, Dr. Madeleine L.H. Campbell offers insight into the moral landscape of human-animal relations through a specific ethical framework that rejects the rights of non-human animals, opting instead for a “qualified utilitarian approach” (2019, 9). For Campbell, animal ethics should not be bound to animal rights or the autonomy of individual animals; she asserts that animal rights should not factor into the moral consideration of animals at all. Since she does not confer animals a moral status (...)

  9. ‘Silent Pandemic’: Evidence-Based Environmental and Public Health Practices to Respond to the COVID-19 Crisis.Morufu Olalekan Raimi, Aziba-Anyam Gift Raimi & Teddy Charles Adias - 2021 - London, UK: IntechOpen.
    Given the unprecedented novel nature and scale of coronavirus and the global nature of this public health crisis, which upended many public/environmental research norms almost overnight. However, with further waves of the virus expected and more pandemics anticipated. The COVID-19 pandemic of 2020 opened our eyes to the ever-changing conditions and uncertainty that exists in our world today, particularly with regards to environmental and public health practices disruption. This paper explores environmental and public health evidence-based practices toward responding to Covid-19. (...)

  10. Scoring Imprecise Credences: A Mildly Immodest Proposal.Conor Mayo-Wilson & Gregory Wheeler - 2016 - Philosophy and Phenomenological Research 92 (1):55-78.
    Jim Joyce argues for two amendments to probabilism. The first is the doctrine that credences are rational, or not, in virtue of their accuracy or “closeness to the truth” (1998). The second is a shift from a numerically precise model of belief to an imprecise model represented by a set of probability functions (2010). We argue that both amendments cannot be satisfied simultaneously. To do so, we employ a (slightly-generalized) impossibility theorem of Seidenfeld, Schervish, and Kadane (2012), who show (...)

  11. (1 other version)Independent Natural Extension for Choice Functions.Jason Konek, Arthur Van Camp & Kevin Blackwell - 2021 - PMLR 147:320-330.
    We investigate epistemic independence for choice functions in a multivariate setting. This work is a continuation of earlier work of one of the authors [23], and our results build on the characterization of choice functions in terms of sets of binary preferences recently established by De Bock and De Cooman [7]. We obtain the independent natural extension in this framework. Given the generality of choice functions, our expression for the independent natural extension is the most general one we are aware (...)

  12. Hypothesis Testing, “Dutch Book” Arguments, and Risk.Daniel Malinsky - 2015 - Philosophy of Science 82 (5):917-929.
    “Dutch Book” arguments and references to gambling theorems are typical in the debate between Bayesians and scientists committed to “classical” statistical methods. These arguments have rarely convinced non-Bayesian scientists to abandon certain conventional practices, partially because many scientists feel that gambling theorems have little relevance to their research activities. In other words, scientists “don’t bet.” This article examines one attempt, by Schervish, Seidenfeld, and Kadane, to progress beyond such apparent stalemates by connecting “Dutch Book”–type mathematical results with principles actually (...)

  13. Distention for Sets of Probabilities.Rush T. Stewart & Michael Nielsen - 2022 - Philosophy of Science 89 (3):604-620.
    Bayesians often appeal to “merging of opinions” to rebut charges of excessive subjectivity. But what happens in the short run is often of greater interest than what happens in the limit. Seidenfeld and coauthors use this observation as motivation for investigating the counterintuitive short run phenomenon of dilation, since, they allege, dilation is “the opposite” of asymptotic merging of opinions. The measure of uncertainty relevant for dilation, however, is not the one relevant for merging of opinions. We explicitly investigate (...)

  14. Conditional Goods and Self-Fulfilling Prophecies: How Literature (as a Whole) Could Matter Again.Joshua Landy - 2013 - Substance 42 (2):48-60.
    This essay argues that literature is neither an intrinsic good (like oxygen) nor a constructed good (like a teddy-bear) but instead a conditional good, like a blueprint. It has immense potential value, but that potential can be actualized only if readers do a certain kind of work; and readers are likely to do that work only if, as a culture, we retain an understanding of what novels and poems both need from us and can give us. This means we (...)
