    Interval scalability of rank-dependent utility.Mikhail V. Sokolov - 2011 - Theory and Decision 70 (3):255-282.
    Luce and Narens (Journal of Mathematical Psychology, 29:1–72, 1985) showed that rank-dependent utility (RDU) is the most general interval scale utility model for binary lotteries. It can be easily established that this result cannot be generalized to lotteries with more than two outcomes. This article suggests several additional conditions to ensure RDU as the only utility model with the desired property of interval scalability in the general case. The related axiomatizations of some special cases of RDU of independent interest (...)

    Expectations, Disappointment, and Rank-Dependent Probability Weighting.Philippe Delquié & Alessandra Cillo - 2006 - Theory and Decision 60 (2-3):193-206.
    We develop a model of Disappointment in which disappointment and elation arise from comparing the outcome received, not with an expected value as in previous models, but rather with the other individual outcomes of the lottery. This approach may better reflect the way individuals are liable to experience disappointment. The model obtained accounts for classic behavioral deviations from the normative theory, offers a richer structure than previous disappointment models, and leads to a Rank-Dependent Utility formulation in a transparent way.

  5. Increasing increment generalizations of rank-dependent theories.R. Duncan Luce - 2003 - Theory and Decision 55 (2):87-146.
    Empirical evidence from both utility and psychophysical experiments suggests that people respond quite differently—perhaps discontinuously—to stimulus pairs when one consequence or signal is set to `zero.' Such stimuli are called unitary. The author's earlier theories assumed otherwise. In particular, the key property of segregation relating gambles and joint receipts (or presentations) involves unitary stimuli. Also, the representation of unitary stimuli was assumed to be separable (i.e., multiplicative). The theories developed here do not invoke separability. Four general cases based on two (...)

    The enormous scale of the available information and products on the Internet has necessitated the development of algorithms that intermediate between options and human users. These algorithms attempt to provide the user with relevant information. In doing so, the algorithms may incur potential negative consequences stemming from the need to select items about which it is uncertain to obtain information about users versus the need to select items about which it is certain to secure high ratings. This tension is an (...)

    Two Measures of the Dependence of Preferential Rankings on Categorical Variables.Grzegorz Lissowski - 2017 - Studies in Logic, Grammar and Rhetoric 50 (1):25-44.
    The aim of this paper is to apply a general methodology for constructing statistical methods, which is based on decision theory, to give a statistical description of preferential rankings, with a focus on the rankings’ dependence on categorical variables. In the paper, I use functions of description errors that are based on the Kemeny and Hamming distances between preferential orderings, but the proposed methodology can also be applied to other methods of estimating description errors.

    Reference-dependent rankings of sets in characteristics space.Wulf Gaertner & Yongsheng Xu - 2011 - Social Choice and Welfare 37 (4):717-728.
    This article uses Lancaster's characteristics approach to rank sets of alternative combinations of commodity characteristics. It is assumed that there exists a reference point or reference level from which the individual evaluates set expansions in appropriate directions. We provide an axiomatic characterization for such a case.

  11. Similarity and Dependence in the Final Ranking of the Philebus.Ross Gilmore - 2022 - Southwest Philosophy Review 38 (1):155-162.
    The so-called Final Ranking of the Philebus offers Socrates’ final evaluation of the relative merits of pleasure and reason in the best life. I begin by examining two common lines of interpretation as they address the criterion according to which the final ranking is organized. I then discuss the role ‘similarity’ has in organizing the investigation throughout the dialogue, from the initial comparison of the two lives (of reason and pleasure singly) down through the final ranking. I then consider the (...)

    On Rank Not Only in Nsop $_1$ Theories.Jan Dobrowolski & Daniel Max Hoffmann - 2024 - Journal of Symbolic Logic 89 (4):1669-1702.
    We introduce a family of local ranks $D_Q$ depending on a finite set Q of pairs of the form $(\varphi (x,y),q(y)),$ where $\varphi (x,y)$ is a formula and $q(y)$ is a global type. We prove that in any NSOP $_1$ theory these ranks satisfy some desirable properties; in particular, $D_Q(x=x)<\omega $ for any finite tuple of variables x and any Q, if $q\supseteq p$ is a Kim-forking extension of types, then $D_Q(q) (...)

    Ranks and pregeometries in finite diagrams.Olivier Lessmann - 2000 - Annals of Pure and Applied Logic 106 (1-3):49-83.
    The study of classes of models of a finite diagram was initiated by S. Shelah in 1969. A diagram D is a set of types over the empty set, and the class of models of the diagram D consists of the models of T which omit all the types not in D. In this work, we introduce a natural dependence relation on the subsets of the models for the 0-stable case which share many of the formal properties of forking. (...)

    A rank for the class of elementary submodels of a superstable homogeneous model.Tapani Hyttinen & Olivier Lessmann - 2002 - Journal of Symbolic Logic 67 (4):1469-1482.
    We study the class of elementary submodels of a large superstable homogeneous model. We introduce a rank which is bounded in the superstable case, and use it to define a dependence relation which shares many (but not all) of the properties of forking in the first order case. The main difference is that we do not have extension over all sets. We also present an example of Shelah showing that extension over all sets may not hold for any (...)

    Distality Rank.Roland Walker - 2023 - Journal of Symbolic Logic 88 (2):704-737.
    Building on Pierre Simon’s notion of distality, we introduce distality rank as a property of first-order theories and give examples for each rankmsuch that$1\leq m \leq \omega $. For NIP theories, we show that distality rank is invariant under base change. We also define a generalization of type orthogonality calledm-determinacy and show that theories of distality rankmrequire certain products to bem-determined. Furthermore, for NIP theories, this behavior characterizesm-distality. If we narrow the scope to stable theories, we observe thatm-distality (...)

    Morley Rank in Homogeneous Models.Alexei Kolesnikov & G. V. N. G. Krishnamurthi - 2006 - Notre Dame Journal of Formal Logic 47 (3):319-329.
    We define an appropriate analog of the Morley rank in a totally transcendental homogeneous model with type diagram D. We show that if RM[p] = α then for some 1 ≤ n < ω the type p has n, but not n + 1, distinct D-extensions of rank α. This is surprising, because the proof of the statement in the first-order case depends heavily on compactness. We also show that types over (D,ℵ₀)-homogeneous models have multiplicity (Morley degree) 1.

  18. Relativized Rankings.Matthew Hammerton - 2020 - In Douglas W. Portmore (ed.), The Oxford Handbook of Consequentialism. New York, USA: Oup Usa. pp. 46-66.
    In traditional consequentialism the good is position-neutral. A single evaluative ranking of states of affairs is correct for everyone, everywhere regardless of their positions. Recently, position-relative forms of consequentialism have been developed. These allow for the correct rankings of states to depend on connections that hold between the state being evaluated and the position of the evaluator. For example, perhaps being an agent who acts in a certain state requires me to rank that state differently from someone else who (...)

  19. Ranks for the Riddle. Spohn Conditionalization and Goodman's Paradox.Wolfgang Freitag & Alexandra Zinke - 2016 - In Wolfgang Freitag, Hans Rott, Holger Sturm & Alexandra Zinke (eds.), Von Rang und Namen. Philosophical Essays in Honour of Wolfgang Spohn (edited book). Münster, Germany: Mentis.
    The paper investigates the prospects of Spohn’s ranking theory with respect to Goodman’s New Riddle of Induction. Based on a novel analysis of the riddle (Freitag [manuscript]), we show it to be an inductive extension of Hansson’s puzzle (Hansson 1992, 1999). As a consequence, a solution needs to take into account the dependence relations between evidential beliefs: “grue” is unprojectible because it depends on evidence whose projection is defeated. It will be suggested that this solution can be implemented into (...)

    About the ranking of isolated habitats with different shapes: An interior-to-edge ratio study.A. R. Imre - 2001 - Acta Biotheoretica 49 (2):115-120.
    Isolated habitats can be compared and ranked by comparing their interior-to-edge ratio (I/E). We would like to show here that results based on ranking by I/E ratio sometimes contradict Diamond's rule, which ranks the most rounded habitat (i.e. most compact) as the best one. The reason for this contradiction is the frequently overlooked size dependence of the I/E. Being the interior-to-edge ratio size dependent, from a given set of habitats of different sizes, compact shaped (rounded) habitats might have worse (...)

    State-Dependent Utilities.Mark J. Schervish, Teddy Seidenfeld & Joseph B. Kadane - unknown
    Several axiom systems for preference among acts lead to a unique probability and a state-independent utility such that acts are ranked according to their expected utilities. These axioms have been used as a foundation for Bayesian decision theory and subjective probability calculus. In this article we note that the uniqueness of the probability is relative to the choice of whatcounts as a constant outcome. Although it is sometimes clear what should be considered constant, in many cases there are several possible (...)

    The interplay of social rank perceptions of Trump and Biden and emotions following the U.S. presidential election 2020.Lea Boecker, Hannes M. Petrowsky, David D. Loschelder & Jens Lange - 2024 - Cognition and Emotion 38 (8):1210-1228.
    The outcome of the 2020 U.S. election between Trump and Biden evoked strong emotions. In U.S. American (Study 1; N = 405) and German (Study 2; N = 123) samples, we investigated how observers’ group membership (i.e. political orientation) and the social rank attainment of both candidates (i.e. dominance vs. prestige) predicted emotional reactions. Trump was generally perceived as more dominant, and Biden as more prestigious. However, perceptions of social rank attainment differed depending on the observers’ political orientation, (...)

  26. Empirical rules of thumb for choice under uncertainty.Rolf Aaberge - 2011 - Theory and Decision 71 (3):431-438.
    A substantial body of empirical evidence shows that individuals overweight extreme events and act in conflict with the expected utility theory. These findings were the primary motivation behind the development of a rank-dependent utility theory for choice under uncertainty. The purpose of this paper is to demonstrate that some simple empirical rules of thumb for choice under uncertainty are consistent with the rank-dependent utility theory.

  27. Counterfactual Dependence and Arrow.Thomas Kroedel & Franz Huber - 2012 - Noûs 47 (3):453-466.
    We argue that a semantics for counterfactual conditionals in terms of comparative overall similarity faces a formal limitation due to Arrow’s impossibility theorem from social choice theory. According to Lewis’s account, the truth-conditions for counterfactual conditionals are given in terms of the comparative overall similarity between possible worlds, which is in turn determined by various aspects of similarity between possible worlds. We argue that a function from aspects of similarity to overall similarity should satisfy certain plausible constraints while Arrow’s impossibility (...)

    Lehrer Meets Ranking Theory.Wolfgang Spohn - 2003 - In Erik Olsson (ed.), The Epistemology of Keith Lehrer. Kluwer Academic Publishers.
    Meets what? Ranking theory is, as far as I know, the only existing theory suited for underpinning Keith Lehrer’s account of knowledge and justification. If this is true, it’s high time to bring both together. This is what I shall do in this paper. However, the result of defining Lehrer’s primitive notions in terms of ranking theory will be disappointing: justified acceptance will, depending on the interpretation, either have an unintelligible structure or reduce to mere acceptance, and in the latter (...)

    We develop a basic theory of rosy groups and we study groups of small Uþ-rank satisfying NIP and having finitely satisfiable generics: Uþ-rank 1 implies that the group is abelian-by-finite, Uþ-rank 2 implies that the group is solvable-by-finite, Uþ-rank 2, and not being nilpotent-by-finite implies the existence of an interpretable algebraically closed field.

    Supererogatory acts are, in some sense, morally better their non-supererogatory alternatives. In this sense, what is it for one option A to be better than an alternative B? I argue for three main conclusions. First, relative rankings are a type of all-in action guidance. If A is better than B, then morality recommends that you A rather than B. Such all-in guidance is useful when acts have the same deontic status. Second, I argue that Right > Wrong: permissible acts are (...)

  31. Testing for context-dependence[REVIEW]John Hawthorne - 2006 - Philosophy and Phenomenological Research 73 (2):443–450.
    How much context-sensitivity is there in English? Cappelen and Lepore’s answer: Not very much. On their view, context-sensitivity is confined to a ‘Basic List’, ‘plus or minus a bit’, that includes pronouns, demonstratives, temporal and spatial adverbs like ‘here’, ‘now’, and ‘yesterday’, and a short list of context dependent nouns and adjectives. Shockingly, the authors claim that ‘Lepore is ready’, ‘Cappelen has had enough’, and ‘Cappelen is quite tall,’ have a context-invariant meaning. Nor is that meaning incomplete, in the sense (...)

    A model of consumption-dependent temptation.Wojciech Olszewski - 2011 - Theory and Decision 70 (1):83-93.
    The paper characterizes axiomatically a class of temptation-driven preferences. The key (but not the only) novelty of the paper is the idea that the alternative which tempts when an item x is consumed may not be the same as the alternative which tempts when another item y is consumed. For any single item to be ultimately consumed, the other items can be ranked by how much they tempt. An individual contemplates, as an alternative consumption, only the item that tempts most. (...)

  33. Anxiety and Decision Making with Delayed Resolution of Uncertainty.George Wu - 1999 - Theory and Decision 46 (2):159-199.
    In many real-world gambles, a non-trivial amount of time passes before the uncertainty is resolved but after a choice is made. An individual may have a preference between gambles with identical probability distributions over final outcomes if they differ in the timing of resolution of uncertainty. In this domain, utility consists not only of the consumption of outcomes, but also the psychological utility induced by an unresolved gamble. We term this utility anxiety. Since a reflective decision maker may want to (...)

    Preference Attitude-Based Method for Ranking Intuitionistic Fuzzy Numbers and Its Application in Renewable Energy Selection.Jian Lin, Fanyong Meng, Riqing Chen & Qiang Zhang - 2018 - Complexity 2018:1-14.
    Many applications of intuitionistic fuzzy sets depend on ranking or comparing intuitionistic fuzzy numbers. This paper presents a novel ranking method for intuitionistic fuzzy numbers based on the preference attitudinal accuracy and score functions. The proposed ranking method considers not only the preference attitude of decision maker, but also all the possible values in feasible domain. Some desirable properties of preference attitudinal accuracy and score functions are verified in detail. A total order on the set of intuitionistic fuzzy numbers is (...)

    The aim of the paper is to propose a preferences representation model under risk where risk perception can be past experience dependent. A first step consists in considering a one period decision problem where individual preferences are no more defined only on decisions but on pairs (decision, past experience). The obtained criterion is used in the construction of a dynamic choice model under risk. The paper ends with an illustrative example concerning insurance demand. It appears that our model allows to (...)

    Rational consequence relations and Popper functions provide logics for reasoning under uncertainty, the former purely qualitative, the latter probabilistic. But few researchers seem to be aware of the close connection between these two logics. I’ll show that Popper functions are probabilistic versions of rational consequence relations. I’ll not assume that the reader is familiar with either logic. I present them, and explicate the relationship between them, from the ground up. I’ll also present alternative axiomatizations for each logic, showing them to (...)

    Neither Straight Nor Crooked: Poetry as Performative Dialectics in the Five Ranks Philosophy of Zen Buddhism.Christopher Byrne - 2020 - Philosophy East and West 70 (3):661-678.
    In traditional and popular accounts, Zen Buddhism is depicted as a practice that rejects literary study and intellectualization in favor of a direct experience of enlightenment that is beyond words. Indeed, the Zen school has traditionally defined itself as a "separate transmission outside the teachings, not dependent on words and letters". Even when regarding the tradition's literary output, Zen literature is famous for its antinomian dialogues replete with outrageous antics, frequent non sequiturs, and crude, illiterate utterances that appear to validate (...)

    Differences in Power Acquisition Between Only and Non-only Children: The Effects of Cooperative Orientation, Competitive Orientation, and Dependency on Parents.Yan Rong, Yulan Han, Linping Dong & Huijuan Bi - 2022 - Frontiers in Psychology 13.
    Drawing upon a developmental perspective, we investigated the differences in power acquisition between only and non-only children as well as the mediating role of cooperative and competitive orientations and the moderating role of dependency on parents. To test our hypotheses, we conducted two field studies in 155 part-time Master of Business Administration students and 375 senior students. Results showed that: non-only children were more likely to achieve higher rank at work than only children; only children were less likely than (...)

    We investigate risk attitudes when the underlying domain of payoffs is finite and the payoffs are, in general, not numerical. In such cases, the traditional notions of absolute risk attitudes, that are designed for convex domains of numerical payoffs, are not applicable. We introduce comparative notions of weak and strong risk attitudes that remain applicable. We examine how they are characterized within the rank-dependent utility model, thus including expected utility as a special case. In particular, we characterize strong comparative (...)

    The empirical adequacy of cumulative prospect theory and its implications for normative assessment.Glenn W. Harrison & Don Ross - 2017 - Journal of Economic Methodology 24 (2):150-165.
    Much behavioral welfare economics assumes that expected utility theory does not accurately describe most human choice under risk. A substantial literature instead evaluates welfare consequences by taking cumulative prospect theory as the natural default alternative, at least where description is concerned. We present evidence, based on a review of previous literature and new experimental data, that the most empirically adequate hypothesis about human choice under risk is that it is heterogeneous, and that where EUT does not apply, more choice is (...)

  45. Why the Repugnant Conclusion is Inescapable.Mark Budolfson & Dean Spears - unknown
    The spectre of the repugnant conclusion and the search for a population axiology that avoids it has endured as a focus of population ethics. This is in part because the repugnant conclusion is often interpreted as a defining problem for totalism, while the implications of averagism and related views are taken to illustrate the theoretical cost of avoiding the repugnant conclusion. However, we show that this interpretation cannot be sustained unless one focuses only on a special case of the repugnant (...)

  47. In Defense of Fanaticism.Hayden Wilkinson - 2022 - Ethics 132 (2):445-477.
    Which is better: a guarantee of a modest amount of moral value, or a tiny probability of arbitrarily large value? To prefer the latter seems fanatical. But, as I argue, avoiding such fanaticism brings severe problems. To do so, we must decline intuitively attractive trade-offs; rank structurally identical pairs of lotteries inconsistently, or else admit absurd sensitivity to tiny probability differences; have rankings depend on remote, unaffected events ; and often neglect to rank lotteries as we already know (...)

    Risk preferences of Australian academics: where retirement funds are invested tells the story.Pavlo R. Blavatskyy - 2016 - Theory and Decision 80 (3):411-426.
    Risk preferences of Australian academics are elicited by analyzing the aggregate distribution of their retirement funds across available investment options. Not more than 10 % of retirement funds are invested as if their owners maximize expected utility under the assumption of constant relative risk aversion with an empirically plausible level of risk aversion. An implausibly high level of risk aversion is required to rationalize any investment into bonds when stocks are available. Not more than 36.54 % of all investments can (...)

    Scale construction from a decisional viewpoint.Michael Smithson - 2006 - Minds and Machines 16 (3):339-364.
    Many quantitative scales are constructed using cutoffs on a continuum with scores assigned to the cutoffs. This paper develops a framework for using or constructing such scales from a decision-making standpoint. It addresses questions such as: How many distinct thresholds or cutoffs on a scale (i.e., what levels of granularity) are useful for a rational agent? Where should these thresholds be placed given a rational agent’s preferences and risk-orientation? Do scale score assignments have any bearing on decision-making and if so, (...)

  50. (1 other version)Production under Uncertainty and Choice under Uncertainty in the Emergence of Generalized Expected Utility Theory.John Quiggin - 2001 - Theory and Decision 51 (2/4):125-144.
    This paper presents a personal view of the interaction between the analysis of choice under uncertainty and the analysis of production under uncertainty. Interest in the foundations of the theory of choice under uncertainty was stimulated by applications of expected utility theory such as the Sandmo model of production under uncertainty. This interest led to the development of generalized models including rank-dependent expected utility theory. In turn, the development of generalized expected utility models raised the question of whether such (...)
