Conviction Narrative Theory (CNT) is a theory of choice underradical uncertainty– situations where outcomes cannot be enumerated and probabilities cannot be assigned. Whereas most theories of choice assume that people rely on (potentially biased) probabilistic judgments, such theories cannot account for adaptive decision-making when probabilities cannot be assigned. CNT proposes that people usenarratives– structured representations of causal, temporal, analogical, and valence relationships – rather than probabilities, as the currency of thought that unifies our sense-making and decision-making (...) faculties. According to CNT, narratives arise from the interplay between individual cognition and the social environment, with reasoners adopting a narrative that feels “right” to explain the available data; using that narrative to imagine plausible futures; and affectively evaluating those imagined futures to make a choice. Evidence from many areas of the cognitive, behavioral, and social sciences supports this basic model, including lab experiments, interview studies, and econometric analyses. We identify 12 propositions to explain how the mental representations (narratives) interact with four inter-related processes (explanation, simulation, affective evaluation, and communication), examining the theoretical and empirical basis for each. We conclude by discussing how CNT can provide a common vocabulary for researchers studying everyday choices across areas of the decision sciences. (shrink)

Critics have argued that behaviorism must necessarily be inadequate to account for complex human behavior whereas cognitive psychology is adequate to account for such behavior. Recently, Fodor has focused this criticism on certain situations in which humans choose among a set of alternatives. We argue that this criticism applies to forms of behaviorism that are reductionistic but not to non-reductionistic behaviorisms like that of Skinner. Non-reductionistic behaviorism can be used to interpret human choice situations of varying degrees of complexity. (...) Such interpretations run into difficulty in accounting for certain aspects of verbal behavior, but so do cognitive theories. Although nothing, in principle, prohibits either type of theory from accounting for complex human behavior, neither current behavioral theory nor current cognitive theory is developed enough at the present time to do so.

Heyman makes a convincing case that a melioration choice strategy is sufficient to produce addictive behavior. But given a plethora of addiction theories, the question is whether melioration theory is superior to rivals more sophisticated than a simple disease model or operant conditioning account. Heyman offers little direct evidence that melioration actually causes the addictions we observe.

This book investigates the relationship between our present and future selves. It focuses specifically on diachronic self-regarding decisions: choices involving our earlier and later selves, in which the earlier self makes a decision for the later self. The author connects the scientific understanding of the neurobehavioral processes at the core of individuals' perceptions of their future selves with the philosophical reflection on individuals' moral relationship with their future selves. She delineates a descriptive theory of the perception of the future (...) self that is based on empirical evidence and that systematizes and integrates the current theoretical literature. She then argues for the morality of prudence and interprets diachronic self-regarding decisions as decisions between two agents-the earlier and later selves-that belong to the realm of intergenerational ethics, which regulates the relationship between contemporary people and future generations. Finally, the author provides a moral theory of prudence based on respect for one's agency. This theory identifies what the present and the future selves owe to one another in diachronic self-regarding decisions. Moral Choices for Our Future Selves will be of interest to researchers and students working in ethics, moral psychology, philosophy of mind, and cognitive science. (shrink)

If we are to believe the proponents of the Theory of Practice and of Rational Choice, the gap between these two paradigmatic approaches cannot be bridged. They rely on ontological premises, theories of motivations and causal models that stand too far apart. In this article, I argue that this theoretical antinomy loses much of its edge when we take as objects of sociological investigation processes of historical change, that is, when we try to specify in theoretical terms how (...) and in which conditions historical actors enact and endorse shifts in patterns of relations as well as shifts in the symbolic and cognitive categories that make these relations significant. I substantiate this argument in light of the distinction between two temporalities of historical change: first, the long waves of gradual change and, second, the short waves of moments of breaks and ruptures. Along the way, I develop an argument about the conditions of emergence of self-limiting norms and the centrality of epistemic beliefs in situations of high disruption. (shrink)

This article traces a normative turn between the middle of the 1940s and the early 1950s reflected in the reformulation, interpretation, and use of rational choice theories at the Cowles Commission for Research in Economics. This turn is paralleled by a transition from Jacob Marschak’s to Tjalling Koopmans’s research program. While rational choice theories initially raised high hopes that they would serve as empirical accounts to inform testable hypotheses about economic regularities, they became increasingly modified and interpreted as (...) normative approaches offering behavioral recommendations for individual agents, organizations, government, and teams. The predefined elements constitutive of these accounts, inspired by simple rules of logic, were now meant to represent the basic demands of rationality and theories of rational decision making specified rules of conduct that were meant to shape rather than explain behavior.

This paper contributes to a theory of rational choice for decision-makers with incomplete preferences due to partial ignorance, whose beliefs are representable as sets of acceptable priors. We focus on the limiting case of `Complete Ignorance' which can be viewed as reduced form of the general case of partial ignorance. Rationality is conceptualized in terms of a `Principle of Preference-Basedness', according to which rational choice should be isomorphic to asserted preference. The main result characterizes axiomatically a new (...) choice-rule called `Simultaneous Expected Utility Maximization'. It can be interpreted as agreement in a bargaining game (Kalai-Smorodinsky solution) whose players correspond to the (extremal) `acceptable priors' among which the decision maker has suspended judgment. An essential but non-standard feature of Simultaneous Expected Utility choices is their dependence on the entire choice set. This is justified by the conception of optimality as compromise rather than as superiority in pairwise comparisons. (shrink)

Registered nurses in psychiatric-mental health nursing continuously balance the ethical principles of duty to do good (beneficence) and no harm (non-maleficence) with the duty to respect patient choices (autonomy). However, the problem of nurses’ level of control versus patients’ choices remains a challenge. The aim of this article is to discuss how nurses accomplish their simultaneous responsibility for balancing patient safety (beneficence and non-maleficence) with patient choices (autonomy) through the theory of protective empowering. This is done by reflecting on (...) interview excerpts about caring from 17 registered nurses taking part in a grounded theory study conducted in three acute urban psychiatric hospital settings in Canada. The interplay between the protective and empowering dimensions of the theory of protective empowering was found to correspond with international, national, and local nursing codes of ethics and standards. The overall core process of protective empowering, and its associated reflective questions, is offered as a new lens for balancing patient safety with choices. (shrink)

This paper reports an experiment which investigates a possible cognitive antecedent of event-splitting effects (ESEs) experimentally observed by Starmer and Sugden (1993) and Humphrey (1995) – the learning of absolute frequency of event category impacting on the learning of probability of event category – and reveals some evidence that it is responsible for observed ESEs. It is also suggested and empirically substantiated that stripped-down prospect theory will accurately predict ESEs in some decision making tasks, but will not perform well (...) in others. This contention, it is argued, is indicative of fundamental descriptive shortcomings in the economic conception of choice under uncertainty and may entail implications beyond the direct concerns of this paper.

Recent work on mood choice considers fine-grained semantic differences among desire predicates (notably, ‘want’ and ‘hope’) and their consequences for the distribution of indicative and subjunctive complement clauses. In that vein, this paper takes a close look at ‘intend’. I show that cross-linguistically, ‘intend’ accepts nonfinite and subjunctive complements and rejects indicative complements. This fact poses difficulties for recent approaches to mood choice. Toward a solution, a broad aim of this paper is to argue that—while ‘intend’ is loosely (...) in the family of desire predicates—it differs from ‘want’ and ‘hope’ in that it has a causative component, and this is relevant to its mood choice behavior, given that causative predicates also systematically reject indicative complements. More concretely, my analysis has three ingredients: (i) following related proposals in philosophy, intention reports have causally self-referential content; (ii) encoding causal self-reference requires abstraction over the complement clause’s eventuality argument; and (iii) nonfinite and subjunctive clauses enable such abstraction but indicative clauses do not. Aside from causative predicates, independent support for the proposal comes from the syntax of belief-/intention-hybrid attitude predicates like ‘decide’ and ‘convince’, anankastic conditional antecedents, aspectual predicates, and memory and perception reports. Synthesizing this result with that of previous literature, the emergent generalization is that subjunctive mood occurs in attitude reports that involve either comparison or eventuality abstraction. Toward a unified theory of mood choice, I suggest that both comparison and eventuality abstraction represent departures from the clausal semantics of unembedded assertions and consequently that subjunctive mood signals such a departure.

There is a surprising disconnect between formal rational choice theory and philosophical work on reasons. The one is silent on the role of reasons in rational choices, the other rarely engages with the formal models of decision problems used by social scientists. To bridge this gap, we propose a new, reason-based theory of rational choice. At its core is an account of preference formation, according to which an agent’s preferences are determined by his or her motivating (...) reasons, together with a ‘weighing relation’ between different combinations of reasons. By explaining how someone’s preferences may vary with changes in his or her motivating reasons, our theory illuminates the relationship between deliberation about reasons and rational choices. Although primarily positive, the theory can also help us think about how those preferences and choices ought to respond to normative reasons. (shrink)

This dissertation argues that we have no good reason to accept any one theory of properties as correct. To show this, I present three possible bases for theory-choice in the properties debate: coherence, explanatory adequacy, and explanatory value. Then I argue that none of these bases resolve the underdetermination of our choice between theories of properties. First, I argue considerations about coherence cannot resolve the underdetermination, because no traditional theory of properties is obviously incoherent. Second, (...) I argue considerations of explanatory adequacy cannot resolve the underdetermination, because every traditional theory of properties lacks the theoretical resources to adequately explain resemblance, causal powers, and predication. However, these inadequacies are easily remedied with theoretical modifications. But this results in an overabundance of modified, but adequate, theories of properties. Third, I argue explanatory virtues cannot resolve the underdetermination, because we have no reason to think explanatory virtues make theories of properties more likely to be true. I reject the common argument that explanatory virtues are truth-conducive in theories of properties because they are truth-conducive in scientific theories. Since none of the three bases for theory choice can resolve the underdetermination, I conclude that we have no good reason to accept any one theory of properties as correct. Finally, I consider the possibility of choosing one theory over the others on pragmatic grounds. But I argue that pragmatic grounds cannot resolve the underdetermination either. Instead, I suggest we accept the view I call 'instrumental pluralism,' which allows practitioners to use whatever theory of properties they find useful. Adviser: Jennifer McKitrick. (shrink)

InA Theory of Justice, Rawls claims that “to each according to his threat advantage is not a conception of justice.” Although it may indeed seem intuitively plausible that a principle based on “threat advantage” cannot count as a principle of justice, it is an altogether different matter to explain why this is so. The question is especially pressing if one bears in mind that such a principle of bargaining in fact underlies many institutionally regulated interactions. Moreover, to the extent (...) that morality is thought of as a mechanism for guaranteeing mutual advantage in the resolution of conflicts, it may indeed seem necessary that it reflect the bargaining power of the parties (in order to make sure that it is indeed advantageous for all of them). In fact, there is a prominent tradition of social-contract theories (from Hobbes to Gauthier) that work under this assumption and claim to provide an answer to what justice requires as much as Rawls's theory does. So seen, the burden of proof seems to fall rather on the shoulders of those committed to claim both that morality is a mechanism that works to the advantage of all and that it nevertheless requires neutralizing all differences in bargaining power.

A variety of recent work in epistemology employs a notion of normality to provide novel theories of knowledge or justification. While such theories are commonly advertised as affording particularly strong epistemic logics, they often make substantive assumptions about the background notion of normality and its logic. This article takes recent normality-based defences of the KK principle as a case study to submit such assumptions to scrutiny. After clarifying issues regarding the natural language use of normality claims, the article isolates a (...) number of choice points regarding the role of contingency, context-sensitivity and similarity in our theorizing with normality. It turns out that both weaker and stronger logics of normality can be motivated depending on how such choices are resolved. And yet securing logics of normality strong enough for normality to play its envisaged role in epistemology may have unwelcome downstream consequences for the resultant theories of knowledge or justification.

A weak form of intuitionistic set theory WST lacking the axiom of extensionality is introduced. While WST is too weak to support the derivation of the law of excluded middle from the axiom of choice, we show that bee.ng up WST with moderate extensionality principles or quotient sets enables the derivation to go through.

This paper will be concerned with the conjunctive interpretation of a family of disjunctive constructions. The relevant conjunctive interpretation, sometimes referred to as a “free choice effect,” (FC) is attested when a disjunctive sentence is embedded under an existential modal operator. I will provide evidence that the relevant generalization extends (with some caveats) to all constructions in which a disjunctive sentence appears under the scope of an existential quantifier, as well as to seemingly unrelated constructions in which conjunction appears (...) under the scope of negation and a universal quantifier.

Medieval authors generally agreed that we have the freedom to choose among alternative possibilities. But most medieval authors also thought that there are situations in which one cannot do otherwise, not even will otherwise. They also thought when willing necessarily, the will remains free. The questions, then, are what grounds the necessity or contingency of the will’s acts, and – since freedom is not defined by the ability to choose – what belongs to the essential character of freedom, the ratio (...) libertatis. This article studies medieval theories of freedom without choice from William of Auxerre to William of Ockham and their background in Augustine, Anselm of Canterbury, and Bernard of Clairvaux.

In this paper, we present set theories based upon the paraconsistent logic Pac. We describe two different techniques to construct models of such set theories. The first of these is an adaptation of one used to construct classical models of positive comprehension. The properties of the models obtained in that way give rise to a natural paraconsistent set theory which is presented here. The status of the axiom of choice in that theory is also discussed. The second (...) leads to show that any classical universe of set theory (e.g. a model of ZF) can be extended to a paraconsistent one, via a term model construction using an adapted bisimulation technique.

It is customary to think that Objective List (“OL), Desire-Satisfaction (“D-S”) and Hedonistic (“HED”) theories of prudential value pretty much cover the waterfront, and that those of the three that are “subjective” are naturalistic (in the sense attacked by Moore, Ross and Ewing), while those that are “objective” must be Platonic, Aristotelian or commit the naturalist fallacy. I here argue for a theory that is both naturalistic (because voluntaristic) and objective but neither Platonic, Aristotelian, nor (I hope) fallacious. In (...) addition, this proposal, called “CHOICE,” is an example of neither an OL, D-S, nor HED theory. It is a theory according to which uncoerced choosings create objective values that we (even everyone) may be wrong about, because valuations are conative rather than epistemic activities. On this view, intrinsic prudential goods necessarily involve likely (pursuant to lawlike regularities) net increases in successful free choosings . (shrink)

We construct peculiar Hilbert spaces from counterexamples to the axiom of choice. We identify the intrinsically effective Hamiltonians with those observables of quantum theory which may coexist with such spaces. Here a self adjoint operator is intrinsically effective if and only if the Schrödinger equation of its generated semigroup is soluble by means of eigenfunction series expansions.

The importance of economic freedom for economic development can no longer be denied. What is often denied, however, is respect for individuals’ rights and personal choices. The role of individual choice is often dismissed or set aside by the development community. In this essay, I argue that inherent to economic freedom’s economic success is the promotion and acceptance of individual choice. Development theory should include recognition of and respect for personal choices, a theory I call “Catfish (...) Man of the Woods” theory of development. (shrink)

This paper reorganizes and further develops the theory of partial meet contraction which was introduced in a classic paper by Alchourron, Gardenfors, and Makinson. Our purpose is threefold. First, we put the theory in a broader perspective by decomposing it into two layers which can respectively be treated by the general theory of choice and preference and elementary model theory. Second, we reprove the two main representation theorems of AGM and present two more representation results (...) for the finite case that "lie between" the former, thereby partially answering an open question of AGM. Our method of proof is uniform insofar as it uses only one form of "revealed preference", and it explains where and why the finiteness assumption is needed. Third, as an application, we explore the logic characterizing theory contractions in the finite case which are governed by the structure of simple and prioritized belief bases. (shrink)

A growing body of empirical evidence suggests the existence of a Paradox of Choice, whereby a larger choice set leads to a lower expected payoff to the decisionmaker. These empirical findings contradict traditional choice-theoretic results in microeconomics and even social psychology, suggesting profound yet unexplained aspects of choice settings/behavior. The Paradox remains largely as a theoretically-rootless empirical phenomenon. We neither understand the mechanisms and conditions that generate it, nor whether the Paradox stems from choice behavior, (...) choice setting, or both. We present a general search model of consumer choice under incomplete information to examine the theoretical existence and conditions for the Paradox. The model departs from traditional microeconomic choice theory in assuming no “cognitive free lunches.” Search and evaluative efforts require time, focus, and opportunity cost in the model, as in real life. The model shows that conditions for Paradox readily exist, diminishing returns to potential value of the choice in choice set size is a necessary condition for a Paradox outcome, that a Paradox outcome can occur with or without a “choice overload” response by the decisionmaker, and that avoidance of a Paradox outcome is an impossibility in some choice settings (primitive to setting regardless of choice behavior). Lastly, we develop a pareto-improving choice set reduction algorithm that eliminates weakly dominated choice set elements and presents the restricted choice set to the decisionmaker. As such, it is shown that the algorithm acts to treat or mitigate the Paradox of Choice, as well as to pareto-improve choice-supporting evaluation more generally. Like established AI recommender systems, the novel algorithm filters choices. In the present case, the filtering is based upon identification of weakly dominated choice set elements. (shrink)

The idea of the positive theory is to avoid the Russell's paradox by postulating an axiom scheme of comprehension for formulas without "too much" negations. In this paper, we show that the axiom of choice is inconsistent with the positive theory $GPK^+ \infty$.
