The doctrinal paradox, the discursive dilemma, and logical aggregation theory

Judgment aggregation theory, or rather, as we conceive of it here, logical aggregation theory generalizes social choice theory by having the aggregation rule bear on judgments of all kinds instead of merely preference judgments. It derives from Kornhauser and Sager??s doctrinal paradox and List and Pettit??s discursive dilemma, two problems that we distinguish emphatically here. The current theory has developed from the discursive dilemma, rather than the doctrinal paradox, and the final objective of the paper is to give the latter its own theoretical development along the line of recent work by Dietrich and Mongin. However, the paper also aims at reviewing logical aggregation theory as such, and it covers impossibility theorems by Dietrich, Dietrich and List, Dokow and Holzman, List and Pettit, Mongin, Nehring and Puppe, Pauly and van Hees, providing a uniform logical framework in which they can be compared with each other. The review goes through three historical stages: the initial paradox and dilemma, the scattered early results on the independence axiom, and the so-called canonical theorem, a collective achievement that provided the theory with its specific method of analysis. The paper goes some way towards philosophical logic, first by briefly connecting the aggregative framework of judgment with the modern philosophy of judgment, and second by thoroughly discussing and axiomatizing the ??general logic?? built in this framework.     

A note on the information content of a consistent pairwise comparison judgment matrix of an AHP decision maker

A decision maker using the Analytic Hierarchy Process (AHP) could be consistent, and still provide no information in the resulting vector of priorities. An extreme example would be a pairwise comparison judgment matrix filled with 1s which is totally consistent under the various definitions of consistency, but has provided no information about the prioritization of alternatives resulting from the decision maker's judgments. In this paper, the quality of a consistent decision maker's judgments using the Analytic Hierarchy Process is placed in the context of the entropy of the resulting vector of priorities. Indeed, it is the purpose of this paper to provide a formal definition of this notion ofentropy of a priority vector, and to provide a framework for a quantitative measurement of the information content of consistent pairwise comparison judgment matrices of a decision maker who is using the Analytic Hierarchy Process. We will prove that the entropy of the vector of priorities for consistent matrices follows a normal distribution and discuss some general considerations of this result.     

Welfare analysis under uncertainty

This article extends Bergsonian welfare analysis to an environment of uncertainty where preferences are not expected utility and may even be state-inconsistent. Given state-inconsistent preferences, the familiar notion of ex ante efficiency is also state-inconsistent. Other efficiency and welfare concepts achieve state consistency by ignoring entirely the prospective preferences of consumers. The framework developed in this article allows welfare judgments to be state-consistent while respecting prospective and conditional preferences. The theory is called inclusive welfare. An application to optimum insurance subsidies illustrates the practical use of the concept.     

Acting Autonomously Versus not Acting Heteronomously

This paper presents a formal framework that purports to capture some aspects of Kant's theory of freedom. In particular, we argue that the analysis sheds further light on Kant's distinction between a negative and a positive concept of freedom. The paper shows that the two concepts are not equivalent: we not only argue that in a Kantian perspective negative freedom need not entail positive freedom, but also that there are situations in which a person can be said to be positively but not negatively free (in a Kantian sense).     

Understanding responsibility: Adolescents' views of delegation and follow-through within the family

Most studies of responsibility emphasize judgments about blame, with cognitive sophistication as the major basis for variations in judgments. The present study explores an alternative. The judgments are about actions that should be taken, with interpersonal relationships as the major basis. In the situations considered, one sibling asks another to take on a job normally done by the asker. The judgments have to do with the responsibility to follow-through, and with the implementation of responsibility (appropriate as against inappropriate ways to remind, give details, or check that the job has been done). Among 14- and 18-year-olds, the majority regarded follow-through as an obligation, with some variation as a function of circumstances. Judgments about appropriate and inappropriate implementation showed a concern with avoiding both negative attributions and the appearance of coercion, in line with the nature of the relationship. Age differences were not significant but gender, in combination with age, was a factor on some judgments. Overall, the results point to the feasibility and the value of considering responsibility in terms of appropriate actions and of linking the analysis of judgments about responsibility to analyses of relationships.     

Improving judgment by reconciling incoherence

This paper discusses how a subject's judgments about his actions, uncertainties and values may be improved by seeking out and reconciling inconsistences between related judgments. Decision theory tells us that there are relationships between coherent judgments, such as between a prior, likelihood and posterior, but does not tell us how a subject is to reconcile his own, possibly incoherent, views. The role of coherence in improving judgments is not clear. This paper discusses whether there is a unique, best reconciliation of incoherent judgments and how such reconciliation could improve decision-making. The basic principles of the coherent view are explained and a language developed in which the problem of reconciliation can be discussed. The practical importance of the problem is emphasized, illustrated by several examples and possible solutions are explored.     

The Not Altogether Social Construction of Emotions: A Critique of Harré and Gillett

Are emotions like sneezes, unwilled, mechanical, or are they like judgments; are they entirely social constructions? Harré and Gillett believe that emotions are exclusively judgments. We argue that their view misses something important. Imagine a person quaking in anger. Both we and Harré and Gillett believe that he is angry only if he has made an implicit judgment, such as I have been transgressed against. But it is the quaking, not the judgment, that gives authenticity and force to the expression of anger. The quaking does not clarify what the actor means but rather it clarifies the relation of the actor to the meaning of his display. What makes it a genuine expression of anger and not a joke or performance is that the quaking is beyond the will. Bodily displays are not necessary to make expressions authentic; anything that shows that the expression is beyond the will will do, for instance, obsessive thoughts, intrusions, or an inability to concentrate. For Harré and Gillett emotions both as displays and feelings do not merely embody judgments but are also speech acts. We argue that an expression, a feeling or flitting through the mind, cannot be a speech act since only the overt can fit into the convention, the strictures of a community. Nor is the display merely a speech act. Since for an emotional display to be genuine it must slip from the lips unbidden. Further, a speech act account makes the emotions arbitrary; they imply that the set of possible emotions is open. We think, on the other hand, that only some sorts of judgments can become part of an emotion; judgments that relate to things that are important enough in a particular culture that judgment display and feeling are linked together involuntarily.     

Context and Scope of Social Work Interventions in Perinatal Mental Health Settings in India

The perinatal period may not be a happy time for all mothers. During this period, some may develop psychiatric complications, which have both biological and psychosocial etiology, and such illness may affect the whole family. Psychosocial aspects may trigger the illness and act as risk and maintaining factors. Social workers need to intervene in this context for optimal functioning of women with perinatal mental health issues and her family. A biopsychosocial framework may be adopted for social work assessment and intervention. Individual, familial, group, and community level intervention is required to address this complex issue, along with other mental health clinicians.     

Anti-racism and the Limits of Equal Opportunities Policy in the Criminal Justice System

In this paper some of the evidence relating to the incidence of racial discrimination in the criminal justice system will be critically examined. It will be argued that equal opportunities policies have been adopted in the British case with the stated aim of tackling the exclusionary effects of racial discrimination. The notion of equal opportunities has been contested not least by those who have advocated anti-racist approaches towards discrimination. Anti-racism has been represented by some of its advocates as reflecting a critique of the authentic source of racism which is loosely defined in terms of social structure and capitalist social relations. The case for reconstituting anti-racism in such a way as to make it relevant to the lives of black offenders will be made. Finally, a framework for developing policies based upon the implementation of specific and clearly stated rights will be made.     

Widening our knowledge concerning young looked after children: the case for research using sociological models of childhood

The Assessment and Action framework for looked after children, designed to improve outcomes for all children in public care and those at home on care orders, is now well established in the UK. This paper offers a critical evaluation of the framework by examining the model of childhood upon which it is premised and by exploring its relationship to children's rights as conceptualized in the United Nations Convention on the Rights of the Child (1989). It will be argued that the particular child development model which underpins the framework addresses the rights of looked after children to protection and provision but does not allow for their participation rights to be sufficiently addressed. A critical review of the research concerning the education and health of looked after children is used to illustrate these points. It will be argued that what are missing are the detailed accounts of looked after children themselves. It is concluded that there is a need for the development of additional research approaches premised upon sociological models of childhood. These would allow for a greater engagement with the participation rights of this group of children and complement the pre‐existing research agenda.     

Determinants and Consequences of Jury Racial Diversity: Empirical Findings, Implications, and Directions for Future Research

One of the ideals underlying any jury system is that those groups of citizens charged with the responsibility of deciding cases should be representative of the communities from which they are selected. Anecdotal and empirical data suggest that reality often falls short of this ideal, however, as many empanelled juries are less diverse than community demographics would dictate. This article reviews the obstacles that stand in the way of jury diversity and typically, by association, jury representativeness. These range from system-related problems regarding jury source lists and summonses to more psychological considerations such as the pervasive, yet difficult-to-identify impact of race on attorneys' jury selection judgments. Drawing on psychological theory and findings, the implications of the failure to empanel diverse juries are also examined, both in terms of laypeople's attitudes toward the legal system as well as the actual decision-making performance of juries. Policy changes intended to promote diverse, representative juries are considered, as are specific directions for future research.     

Democratic demand for a social Europe? Preferences of the European citizenry

Within the literature on European integration there is a widespread assumption that Europe is in need of intensified and more effective supranational social policy cooperation. However, on the political level it is doubtful whether such measures are welcomed by the national electorates. This article addresses this issue empirically by asking whether there is public demand for promoting greater European welfare policy cooperation and what are the determinants of such a demand. The data source used is the Eurobarometer survey 2000. A number of hypotheses dealing with socio-structural differences, the effects of welfare regime types, the subjective evaluation of the integration process and the role of identity will be scrutinised. Overall, the results indicate that at the attitudinal 'grass root' level there is no unequivocal support for a European welfare responsibility and that some fundamental cleavages are present. It is the regional and cultural aspects, especially, which turn out to be having an effect and to be influencing future political conflicts. A common European welfare arrangement, therefore, cannot be regarded as a solution to the problems the European Union is facing; rather it will raise new and severe problems of finding social and political support.     

Mixture of Maximal Quasi Orders: a new Approach to Preference Modelling

Normative theories suggest that inconsistencies be pointed out to the Decision Maker who is thus given the chance to modify his/her judgments. In this paper, we suggest that the inconsistencies problem be transferred from the Decision Maker to the Analyst. With the Mixture of Maximal Quasi Orders, rather than pointing out incoherences for the Decision Maker to change, these inconsistencies may be used as new source of information to model his/her preferences.     

Assessing small non-zero perceptions of chance: The case of H1N1 (swine) flu risks

Feelings of invulnerability, seen in judgments of 0% risk, can reflect misunderstandings of risk and risk behaviors, suggesting increased need for risk communication. However, judgments of 0% risk may be given by individuals who feel invulnerable, and by individuals who are rounding from small non-zero probabilities. We examined the effect of allowing participants to give more precise responses in the 0–1% range on the validity of reported probability judgments. Participants assessed probabilities for getting H1N1 influenza and dying from it conditional on infection, using a 0–100% visual linear scale. Those responding in the 0–1% range received a follow-up question with more options in that range. This two-step procedure reduced the use of 0% and increased the resolution of responses in the 0–1% range. Moreover, revised probability responses improved predictions of attitudes and self-reported behaviors. Hence, our two-step procedure allows for more precise and more valid measurement of perceived invulnerability.     

Moral judgments,gender, and antisocial preferences: an experimental study

We study questionnaire responses to situations in which sacrificing one life may save many other lives. We demonstrate gender differences in moral judgments: males are more supportive of the sacrifice than females. We investigate a source of the endorsement of the sacrifice: antisocial preferences. First, we measure individual proneness to spiteful behavior, using an experimental game with monetary stakes. We demonstrate that spitefulness can be sizable—a fifth of our participants behave spitefully—but it is not associated with gender. Second, we find that gender is consistently associated with responses even when we account for individual differences in the propensity to spitefulness.     

Subjective utility with upper and lower probabilities on finite states

This article is concerned with thresholds of discrimination of preference judgments under uncertainty. We establish an axiomatic characterization for a threshold representation, where thresholds are represented by inexact measurement of subjective probabilities, i.e., upper and lower probabilities. Since upper and lower probabilities need not be additive, the representational form adopts the Choquet integration.     

Bad Deaths

Evidence is presented to show that people are willing to pay a premium to avoid bad deaths—deaths that are especially dreaded, uncontrollable, involuntarily incurred, and inequitably distributed. Public judgments of this kind help explain the demand for regulation. But some of these judgments do not justify current policies, because they stem from selective attention and confusion. Few causes of death are entirely uncontrollable or faced wholly involuntarily; the issue is not whether they can be controlled but at what cost. But three kinds of bad deaths deserve special attention: those imposing high externalities, those preceded by unusual pain and suffering, and those producing distributional inequity.     

Dominance criteria for welfare comparisons: using equivalent income to describe differences in needs

The article demonstrates that the dominance approach—often used for the measurement of welfare in a population in which there are different household types (see e.g., Atkinson and Bourguignon, Arrow and the foundations of the theory of economic policy, 350–370, 1987)—can be based on explicit value judgments on the households’ living standard. We define living standard by equivalent income (functions) and consider classes of inequality averse social welfare functions: Welfare increases if the inequality of living standard is decreased. In this framework, we suggest three new dominance criteria and obtain characterizations of second degree stochastic dominance and of two criteria proposed by Bourguignon (Journal of Econometrics 42:67–80, 1989).     

Social Representations Theory and young Africans' creative narratives about human immunodeficiency virus/acquired immune deficiency syndrome, 1997–2014

Research on social representations (SRs) has often focused more on categorical than narrative‐based representations. However, narratives are considered to play a key role in the organization of SRs. This article describes an empirical study of some 2000 creative narratives about human immunodeficiency virus written by young Africans from five countries between 1997 and 2014 and examines the theoretical, methodological and applied relevance of Social Representations Theory (SRT) for this study and the implications of the study for the intersection between narrative and SRT. The study is unusual within the SR paradigm: it is temporal and cross‐national; addresses a subject whose science has evolved over time; and uses creative narratives as its data source. A narrative perspective foregrounds holistic understandings of SRs as systems of thought. Creative narratives fit well within an SR framework. Our triangulating methodologies foreground categorical or narrative dimensions depending on the objectives of specific sub‐studies. Central Core Theory provides a framework to articulate stability and change within narrative representations. In creative narrative, objectification also happens at the level of plot and characters, such that dominant cultural narratives can be viewed as a form of hegemonic SR. We link with health communication and embrace more critical streams within SR research.
