Our understanding of the decisions made under scenarios where both descriptive and experience-based information are available is very limited. Underweighting of small probabilities was observed in the gain domain when both description and experience were provided. The divergence observed from the prospect theory suggests a need for a separate or modified theory of decision making under risk. Recent studies suggest a possible role of probability weighting in the choice behaviour under risk. We investigated both gain and loss domains with (...) and without feedback for small and large probability conditions. We characterized the shape of the probability weighting function by a two-parameter functional form representing discriminability (concave-convex shape) and attractiveness (level of absolute weights relative to objective probability). We replicated four-fold pattern of risk attitude on non-WEIRD population. We find that feedback leads to underweighting of small probabilities and overweighting of large probabilities in the gain domain and overall underweighting of probabilities in the loss domain. We find that underweighting of small probabilities is driven by changes in discriminability and attractiveness components in the gain domain and changes in the attractiveness component in the loss domain. We have interpreted the results by proposing an updated belief-based account of decisions under uncertainty in which feedback, when available, influences the probability weighting mediating the choice behaviour.

South Africa’s Choice on Termination of Pregnancy Act of 1996 implicitly expresses the attitude that the prenatal detection of foetal abnormality justifies selective abortion, even at a stage when abortion is in general morally prohibited. It will be argued that this attitude is logically incompatible with a simultaneous commitment to non-discrimination against persons with disabilities, in that the Act makes allowance for the subjection of beings that are considered to be morally significant, but that exhibit disabling characteristics, to (...) worse treatment than their non-disabled counterparts, despite the fact that this differential treatment is not always justified by the presence of impairment.

A wide array of species throughout the animal kingdom has shown the ability to distinguish between quantities. Aside from being important for optimal foraging decisions, this ability seems to also be of great relevance in group-living animals as it allows them to inform their decisions regarding engagement in between-group conflicts based on the size of competing groups. However, it is often unclear whether these animals rely on numerical information alone to make these decisions or whether they employ other cues that (...) may covary with the differences in quantity. In this study we used a touch screen paradigm to investigate the quantity discrimination abilities of two closely related group-living species, wolves and dogs, using a simultaneous visual presentation paradigm. Both species were able to successfully distinguish between stimuli of different quantities up to 32 items and ratios up to 0.80, and their results were in accordance with Weber's law (which predicts worse performances at higher ratios). However, our controls showed that both wolves and dogs may have used continuous, non-numerical cues, such as size and shape of the stimuli, in conjunction with the numerical information to solve this task. In line with this possibility, dogs' performance greatly exceeded that which they had shown in other numerical competence paradigms. We discuss the implications these results may have on these species' underlying biases and numerical capabilities, as well as how our paradigm may have affected the animals' ability to solve the task.

People with cognitive impairments often have difficulties formulating, understanding, or articulating decisions that others judge reasonable. The frequent response shifts decision-making authority to substitutes through advance directives of the person or guardianship orders from a court. The Convention on the Rights of People with Disabilities defends supported decision-making as an alternative to such forms of supplanted decision-making. But supported decision-making raises both metaphysical questions—what is required for a decision to be the person’s own?—and epistemological questions: how do we know what (...) persons judge to be their good, when they have difficulty conceptualizing and articulating? It raises practical questions, too, such as protection against risks of exploitation. This article uses a non-discrimination account of legal personhood drawn from the CRPD to explore how common features of decisions employed by people without cognitive disabilities are important in supported decision-making too. These features include prostheses, guardrails, relationships, and social contexts. (shrink)

This paper examines the problem of selecting a number of candidates to receive a good (admission) from a pool in which there are more qualified applicants than places. I observe that it is rarely possible to order all candidates according to some relevant criterion, such as academic merit, since these standards are inevitably somewhat vague. This means that we are often faced with the task of making selections between near-enough equal candidates. I survey one particular line of response, which says (...) that we should allow our choice of borderline candidates to be guided by non-relevant criteria such as gender-balancing. I argue that this would not, as commonly objected, be a case of sex discrimination if it is to be applied either in favour of men or women. Nonetheless, I argue that such policies are problematic because they violate the demand for publicity, which is required for legitimacy and to assure everyone that discrimination has not in fact taken place. Instead, I suggest that, if we are concerned to avoid discrimination, there may be a case for using lotteries as tie-breakers, not on grounds of fairness but to prevent taint of bias. (shrink)

In this paper, I argue that it is morally permissible and should be legally permissible for state and private professional schools to discriminate against women. By professional schools, I mean law, medical, and business schools. More specifically, I argue that such schools may discount womens applications to the degree that they are likely to produce less than male counterparts. The argument differs with regard to state and private institutions because of the greater moral elbowroom that private institutions have. The argument (...) for state professional schools depends on the purpose of state professional programs. If the purpose of these programs is to provide professional services to citizens, and I argue that it is, then the state professional schools are permitted to do such discounting. My argument also supports the stronger claim that state schools have an obligation to do so, but I will focus on the weaker claim. Given their wider choice of goals, private schools are also permitted to discount womens applications, but they are not obligated to do so. In this paper, then, I provide an argument for the moral permissibility of such discounting. (shrink)

Moral choice, as a precursor to behaviour, has an important influence on the success or failure of business entities. According to Rest, 1983, Morality, Moral Behavior and Moral Development (John Wiley & Sons, New York), moral choice is prompted, amongst other things, by a motivational component. With this in mind, data obtained from a sample of four hundred financial sector operatives, employed in a rapidly developing region of China, was used to construct a relatively stable set of motivational (...) typologies which could be used to predict choice within an agency-based context. A non-egoist version of the agency theory was developed, which permitted the modelling of alternative heuristic patterns. Altruists and persons identified as bordering on the verge of being classified as psychological egoists, refused to reorganize their motives when responding to a problem that included both moral hazard and adverse selection criteria. It was also possible to identify certain personal and contextual issues which discriminated between the typologies. (shrink)

To rationalize the selection of a research methodology, one must understand its philosophical origins and unique characteristics. This process can be challenging in the landscape of evolving qualitative methodologies. Grounded theory is a research methodology with a distinct history that has resulted in numerous approaches. Although the approaches have key similarities, they also have differing philosophical assumptions that influence the ways in which their methods are understood and implemented. The purpose of this discussion paper is to compare and contrast three (...) widely used grounded theory approaches with key distinguishing characteristics, enabling a more thoughtful selection of approach. This work contributes to the existing literature through contrasting classic Glaserian grounded theory, Straussian grounded theory, and constructivist grounded theory in a systematic manner with prominent distinguishing characteristics developed from a review of the literature. These characteristics included historical development, philosophical perspective, role of the researcher, data analysis procedures, perspective of the grounded theory, and strengths/critique. Based on this analysis, three considerations are proposed to direct the methodological choice for a study: purpose, philosophy, and pragmatics. Understanding the similarities and differences in the grounded theory approaches can facilitate methodological transparency and determine the best fit for one's study and worldview as a researcher.

In lieu of an abstract, here is a brief excerpt of the content: Choice and Virtue in the Nicomachean Ethics ALFRED R. MELE COM~rNTATORS ON THr Nicomachean Ethics (NE) have long been laboring under the influence of a serious misunderstanding of one of the key terms in Aristotle's moral philosophy and theory of action. This term is prohairesis (choice), the importance of which is indicated by Aristotle's assertions that choice is the proximate efficient cause of action (NE (...) 6. 1139a31--32) and that in which "the essential elements of virtue and character" lie (NE 8. x163a2'~-23). The accepted view is that Aristotle employs two importantly different notions of choice in the NE, one on which the term refers exclusively to means or things which are pros (toward, related to)' ends and another on which it does not have this reference? This "two notion" interpretation is motivated by the following three considerations: i. Aristotle's good or virtuous agent is said (NE 2. 11o5a28-33, cf. NE 6. 1144ax8-2o ) to choose actions for their own sakes; but, according to the This paper is derived in part from a chapter of my doctoral dissertation, which was submitted to the University of Michigan in January of 1979. 1 would like to express my gratitttde to the chairman of my dissertation committee, Nicholas P. White, for his comments and criticisms on the relevant sections during the preparation of my dissertation and to theJHP's anonymous reviewers for their helpful criticisms and queries. ' It has often been pointed out that things which are pros an end are not necessarily "means," in the ordinary sense of the word. E.g., constituents of an end are pros the end, but they are not means to it. See, e.g., Nicomachean Ethics, Book 6, trans. Leonard H. G. Greenwood (Cambridge: Cambridge University Press, 19o9), pp. 46-47, 53ff.: and John M. Cooper, Reason and Human Good in Aristotle (Cambridge: Harvard University Press, 1975), pp. 1o-22. ' Among the many proponents of this "two notion" interpretation are William D. Ross and Donald J. Allan. See Ross, Aristotle, 5th ed. (London: Methuen, t953), p. 2oo. See Allan, The Philosophy of Aristotle, 2nd ed. (London: Oxford University Press, 197o), p. 132; idem, "Aristotle 's Account of the Origin of Moral Principles," Xlth International Congress of Philosophy 12 (1953):124; idem, "The Practical Syllogism," in Autour d'Aristote, Studies for A. Mansion (Louvain : Publications Universitaires, 1955). Richard Sorabji, in "Aristotle on the Role of Intellect in Virtue" (Proceedings of the Aristotelian Society 74 l t973-74]:t t6), says that he has noticed sixteen commentators who take this view. [4o5] 406 HISTORY OF PHILOSOPHY so-called formal account of prohairesis (NE 3. 2-3, 6. 2), the object of choice is what has been decided upon by deliberation (bouleuais), and what is decided upon by deliberation is a "means" to an end. 2. Aristotle says that choice is "closely bound up with virtue" and "discriminates characters better than actions do" (1 1t lb5; cf. t i lob3t, 1117a 5, 1163a22, 1t64bi); but commentators argue that these claims about choice are false unless choice is "of ends." 3. Though Aristotle holds that the impetuous akrat~s (incontinent agent) does not deliberate (e.g., t 152a 18-19), he says that the akrat~s' choice is good (1152ax5--17; cf. l l51a5-- 7, 29--32); and this appears to contradict his position in Book 3 that the object of choice is what is decided upon by deliberation, s In this paper I shall show that only one (philosophically significant) notion ofprohairesis is employed in the NE, namely, the notion developed in the "formal account" of deliberation and choice (3- 2-3, 6. 2), according to which choice is specifically of things which are pros ends. This point has several interesting applications. For example, it makes it easier to find in Aristotle (as I shall briefly explain) a comprehensive theory of practical reasoning or inference rather than several unconnected accounts of what practical inference is like in different types of cases; and it is helpful in clarifying what is involved in the evaluation of character on Aristotle's view (see Sec. ~). However, though I do think that the main point to be made... (shrink)

In the article “On Avoiding Deep Dementia,” Norman Cantor defends a position that I suspect many readers share. In my years writing and speaking on advance directives and dementia, I've found that most people support one of two positions. They are convinced either that advance choices should control the treatment dementia patients receive or that the welfare of a person with dementia should sometimes take priority over earlier choices. As Cantor points out, I support the second position.I agree with several (...) of Cantor's arguments. Where Cantor and I part ways is over the degree of control that advance directives should exert over the care of persons with moderate dementia. Although I don't welcome the prospect of living with dementia, I believe that people with the condition should be represented in the debate over treatment standards. It's not surprising that many, perhaps most, people unaffected by dementia think that their preferences should control the care they would receive as dementia patients. But people taking this position are neglecting the concerns and interests they may have as dementia patients. (shrink)

Here, we provide an ethical analysis of discrimination in private insurance to guide the application of non-discriminatory algorithms for risk prediction in the insurance context. This addresses the need for ethical guidance of data-science experts, business managers, and regulators, proposing a framework of moral reasoning behind the choice of fairness goals for prediction-based decisions in the insurance domain. The reference to private insurance as a business practice is essential in our approach, because the consequences of discrimination and (...) predictive inaccuracy in underwriting are different from those of using predictive algorithms in other sectors. Here we focus on the trade-off in the extent to which one can pursue indirect non-discrimination versus predictive accuracy. The moral assessment of this trade-off is related to the context of application—to the consequences of inaccurate risk predictions in the insurance domain. (shrink)

The practice of screening potential users of reproductive services is of profound social and political significance. Access screening is inconsistent with the principles of equality and self-determination, and violates individual and group human rights. Communities that strive to function in accord with those principles should not permit access screening, even screening that purports to be a benign exercise of professional discretion. Because reproductive choice is controversial, regulation by law may be required in most jurisdictions to provide effective protection for (...) reproductive rights. In Canada, for example, equal access can, and should be, guaranteed by federal regulations imposing strict conditions on the licences of fertility clinics. (shrink)

This book addresses the growing use of computerized systems to influence people’s decisions without their awareness, a significant but underappreciated sea-change in the way the world works. To assess these systems, this volume’s contributors explore the philosophical and ethical dimensions of algorithms that guide people’s behavior by nudging them toward choices preferred by systems architects. Particularly in an era of heightened awareness of bias and discrimination, these systems raise profound concerns about the morality of such activities. This volume brings (...) together a diverse array of thinkers to critically examine these nudging systems. Not only are high-level perspectives presented, but so too are of those who use them on a day-to-day basis. While algorithmic nudging can produce benefits for users there are also many less-obvious costs to using such systems, costs that require examination and deliberation. This book is a major step towards delineating these concerns and suggesting ways to provide a sounder basis for future policies for algorithms. It should be of interest to system designers, public policymakers, scholars, and those who wonder more deeply about the nudges they receive from various websites and on their phones. (shrink)

This paper contributes to debates over algorithmic discrimination with particular attention to structural theories of racism and the problem of “proxy discrimination”—discriminatory effects that arise even when an algorithm has no information about socially sensitive characteristics such as race. Structural theories emphasize the ways that unequal power structures contribute to the subordination of marginalized groups: these theories thus understand racism in ways that go beyond individual choices and bad intentions. Our question is, how should a structural understanding of (...) racism and oppression inform our understanding of algorithmic discrimination and its associated norms? Some responses to the problem of proxy discrimination focus on fairness as a form of “parity,” aiming to equalize metrics between individuals or groups—looking, for example, for equal rates of accurate and inaccurate predictions between one group and another. We argue that from the perspective of structural theories, fairness-as-parity is inapt in the algorithmic context; instead, we should be considering social impact—whether a use of an algorithm perpetuates or mitigates existing social stratification. Our contribution thus offers a new understanding of what algorithmic racial discrimination is. (shrink)

With over 10 000 bases of DNA being sequenced around the world per minute, it is vital that ethical discussion continues to keep pace with genetic research.

Proceeding (...) with the themes of rights, justice, and harm, problems addressed by the authors include: the significance of the moral difference between treating genetic disease and altering personality characteristics; whether the utilisation of prenatal interventions to avoid disability discriminates against the disabled, and who should have control ….

In the last two decades the Israeli educational system has undergone major changes which have transformed it from a state-controlled, overly bureaucratic and almost fully state-financed system into a decentralized, partly locally controlled and increasingly privately financed system. Advocates of this transformation of the educational system appeal to the ideal of parental choice. They argue that the implementation of parental choice programs in education shows more respect to the children and their unique talents, take their self-realization seriously and (...) promotes equal opportunities in education. The ideal of parental choice is also upheld in relation to value of cultural pluralism. Supporters of educational autonomy advocate the restructuring of schools in a way allowing them to develop a unique climate and curriculum consistent with respective communities and parents' preferences. The aim of this paper is to assess critically the changes that Israeli educational system has undergone against the background of the principle of equal educational opportunities. The main claim of the paper is that these changes undermine this principle. It will be argued that these changes actually cater mainly to the educational interests of middle and upper middle classes in Israeli society. (shrink)

This paper discusses the relationship between internationalisation, mobility, quality and equality in the context of recent developments in research policy in the European Research Area (ERA). Although these developments are specifically concerned with the growth of research capacity at European level, the issues raised have much broader relevance to those concerned with research policy and highly skilled mobility. The paper draws on a wealth of recent research examining the relationship between mobility and career progression with particular reference to a recently (...) completed empirical study of doctoral mobility in the social sciences (Ackers et al. Doctoral Mobility in the Social Sciences. Report to the NORFACE ERA-Network, 2007). The paper is structured as follows. The first section introduces recent policy developments including the European Charter for Researchers and Code of Conduct for the Recruitment of Researchers and the European Commission’s Green Paper on the ERA. The discussion focuses on concerns around the definition of ‘mobility’ and the tendency (in both policy circles and academic research) to conflate different forms of mobility and to equate these with notions of excellence or quality. Scientific mobility is shaped as much by ‘push’ factors (limited opportunity) as it is by the ‘draw’ of excellence. Scientists are exercising a degree of ‘choice’ within a specific and individualised framework of constraints. The following sections consider some of the ‘professional’ and ‘personal’ factors shaping scientific mobility and the influence that these have on the relationship between mobility, internationalisation and excellence. The paper concludes that mobility is not an outcome in its own right and must not be treated as such (as an implicit indicator of internationalisation). To do so contributes to differential opportunity in scientific labour markets reducing both efficiency and equality. (shrink)

Under the presupposition that human time perception is distorted in intertemporal choice, this study constructs a time scale in the framework of axiomatic measurement. First, the conditions (homogeneity of degree one or two) to identify the form of a time scale are proposed so that one can determine whether the hyperbolic or exponential is a more suitable function for modeling people’s discounting. Homogeneity of degree one implies that subjective time delay is measured by a power scale and its discount (...) function becomes a power-exponential type, whereas homogeneity of degree two implies that subjective time delay is measured by a log scale and its discount function becomes a hyperbolic type. Second, a method is shown for constructing a model that can reflect subadditive and superadditive discounting. A non-commutative and non-associative concatenation operation is provided to generate a time string consisting of subdivided durations that incorporates the effect of repeated delay with a subdivided duration. The discounting model is yielded by substituting these strings in an exponential model equipped with a generalized time scale, and the determination of subadditivity or superadditivity depends on whether the discount function value of a product by the non-commutative and non-associative operation is, respectively, smaller or greater than that of a product by an operation of the usual extensive structure.

Prenatal diagnosis utilizes invasive procedures such as amniocentesis, chorionic villus sampling, cord blood sampling and pre-implantation genetic diagnosis. These techniques can diagnose serious foetal illnesses and this therefore provides valuable information to couples, helping them to prepare for the birth of an affected child. It also affords women the freedom to decide whether to terminate a pregnancy. The selective termination of foetuses with serious disabilities does not represent disability discrimination because women and parents are actually rejecting the disability, rather (...) than the foetus itself More significantly, the choice to abort a foetus with a serious illness or disability is an intensely private and personal exercise that does not and cannot be reflective of a wider public morality. Exactly the same can be said of the choice to selectively abort foetuses based solely on their sex. The private choice of women in this respect does not amount to the social devaluation of women. Firstly, it is an erroneous assumption that women in Australia prefer male babies. Secondly, even if there is a preference for male babies, banning prenatal sex selection would be treating just one of many symptoms of sexism, rather than curing the primary causes. The moral right of all women to reproductive freedom is an embodiment of their equal value in society. (shrink)

We describe a patient LS, profoundly deaf in both ears from birth, with underdeveloped superior temporal gyri. Without hearing aids, LS displays no ability to detect sounds below a fixed threshold of 60 dBs, which classifies him as clinically deaf. Under these no-hearing-aid conditions, when presented with a forced-choice paradigm in which he is asked to consciously respond, he is unable to make above-chance judgments about the presence or location of sounds. However, he is able to make above-chance judgments (...) about the content of sounds presented to him under forced-choice conditions. We demonstrated that LS has faint sensations from auditory stimuli, but questionable awareness of auditory content. LS thus has a form of type-2 deaf hearing with respect to auditory content. As in the case of a subject with acquired deafness and deaf hearing reported on a previous occasion, LS’s condition of deaf hearing is akin in some respects to type-2 blindsight. As for the case of type 2 blindsight the case indicates that a form of conscious hearing can arise in the absence of a fully developed auditory cortex. (shrink)

As a great synthesist for the School of Principles of the Northern and Southern Song dynasties, Zhu Xi’s influence over the School of Principles was demonstrated not only through his positive theoretical creation, but also through his choice and critical awareness. Zhu’s relationship with Confucianism and Buddhism is a typical case; and his activities, ranging from his research of Buddhism (the Chan School) in his early days to his farewell to the Chan School as a student of Li Dong (...) from Yanping and then to his critical awareness of the Chan School, developed in his association with Wang Yingchen, set the entire course of his relationship with Confucianism and Buddhism. It fostered his antagonistic attitude towards the Chan School, which lasted his entire life. Zhu approached the Chan School mainly as an objective social and cultural phenomenon; his discrimination between Confucianism and Buddhism was from an epistemological point of view; and his refutation of the Chan School was mainly from the point of view of language and methodology, an antagonistic attitude of how to face learning. Therefore, his opposition to the Chan School not only directly fostered an awareness of the Confucians of the Ming dynasty against Buddhism, who simply viewed the latter as an external and objective existence, but to a certain extent resulted in the disappearance of the transcendence of the School of Principles, and caused a total change in academic direction during the Ming and Qing dynasties and the formation of the Qianjia Hanxue . What is more, such an opposition to Buddhism continues to influence people’s understanding of the School of Principles. (shrink)

In my previous thinking about the considerations that go under the heading of the “expressivist argument,” I have been fascinated chiefly by two of its features: its semantic commitments and its independence from disputes about the moral standing of fetuses. Abortions prompted by prenatal testing are undertaken because of indications that the fetus has physical features that would be configured as disabilities in the social world into which it would otherwise emerge. The expressivist argument's allegation, as I have understood it, (...) is that abortions so motivated convey semantic content—“send a message”—to people who are currently living with disabilities that is somehow insulting, hateful, dismissive, or disparaging. It is thus uncontroversial moral subjects who are wronged, not—or, at least, not necessarily—the aborted fetuses. So far as this argument goes, a person might hold strongly pro-choice views about abortion generally and still object to “selective” abortions. (shrink)

Accountants and auditors are often faced with ethical dilemmas, which they have to process using resources available to them. Although they may be sensitive to the ethicality of the issues and have the cognitive ability to work through a judgment process, the final action they take may be dependent on a number of motivational factors, endogenous to the issue. Agency issues are a continuing area of concern providing accountants with an ability to shirk their responsibilities and hide confidential information, which (...) may affect their career prospects if disclosed. This ongoing study explores these notions within a stakeholder context and uses a post test only field experiment to gain evidence to support the existence of an agency problem and that membership to one of a number of motivational typologies directly affects the way accountants respond to ethical issues. This association causes them to adopt informational heuristics that may result in less than optimal decisions. This study identified two specific endogenous constructs, namely social consensus and venal intent that discriminate between motivational types and which possibly provide psychological underpinnings explaining membership orientation.

Human listeners are assumed to apply different strategies to improve speech recognition in background noise. Young listeners with normal hearing, e.g., have been shown to follow the voice of a particular speaker based on the fundamental and formant frequencies, which are both influenced by the gender, age, and size of the speaker. However, the auditory and cognitive processes that underlie the extraction and discrimination of these voice cues across speakers may be subject to age-related decline. The present study aimed (...) to examine the utilization of F0 and formant cues for voice discrimination in older adults with hearing expected for their age. Difference limens for VD were estimated in 15 healthy older adults and 35 young adults using only F0 cues, only formant frequency cues, and a combination of F0 + formant frequencies. A three-alternative forced-choice paradigm with an adaptive-tracking threshold-seeking procedure was used. Wechsler backward digit span test was used as a measure of auditory working memory. Trail Making Test was used to provide cognitive information reflecting a combined effect of processing speed, mental flexibility, and executive control abilities. The results showed that the mean VD thresholds of the older adults were poorer than those of the young adults for all voice cues, although larger variability was observed among the older listeners; both age groups found the formant cues more beneficial for VD, compared to the F0 cues, and the combined cues resulted in better thresholds, compared to each cue separately; significant associations were found for the older adults in the combined F0 + formant condition between VD and TMT scores, and between VD and hearing sensitivity, supporting the notion that a decline with age in both top-down and bottom-up mechanisms may hamper the ability of older adults to discriminate between voices. The present findings suggest that older listeners may have difficulty following the voice of a specific speaker and thus implementing doing so as a strategy for listening amid noise. This may contribute to understanding their reported difficulty listening in adverse conditions. (shrink)

Thirty years of debate have passed since the term “Rule of Rescue” has been introduced into medical ethics. Its main focus was on whether or why medical treatment for acute conditions should have priority over preventive measures irrespective of opportunity costs. Recent contributions, taking account of the widespread reluctance to accept purely efficiency-oriented prioritization approaches, advance another objection: Prioritizing treatment, they hold, discriminates against statistical lives. The reference to opportunity costs has also been renewed in a distinctly ethical fashion: It (...) has been stipulated that favoring help for identifiable lives amounts to a lack of benevolence for one’s fellow creatures. The present article argues against both objections. It suggests that the debate’s focus on consequences should be reoriented by asking which aspects of such states of affairs are actually attributable to a decision maker who judges within a specific situation of choice.
