Eye tracking is used to investigate human choice procedures. We infer from eye movement patterns in choice problems where the deliberation process is clear to deliberations in problems of choice between two lotteries. The results indicate that participants tend to compare prizes and probabilities separately. The data provide little support for the hypothesis that decision makers use an expected utility type of calculation exclusively. This is particularly true when the calculations involved in comparing the lotteries are complicated.

Phytomass cultivation for energy use is increasingly popular in Europe for high profits guaranteed by subsidy. Although public interest in ecology is on an increasing level, direct combustion is still preferred even though scholars have been warning about formations of hazardous compounds for a long-time. However, the reduction of subsidies would negatively affect an already bad situation in Czech agriculture, since most farmers became fully dependent on subsidies due to quotas, restrictions, and other unequal business conditions in European Union. It (...) was proved in a commercial scale that an alternative phytomass energy utilizing technology consisting of steam explosion and subsequent anaerobic fermentation may be run solely on the waste heat without any further addition of chemicals. Behavior analysis of present and future agriculture decision-makers showed that none of the farmers who visited the facility cared about ecological consequences. On the other hand, ost students from the Faculty of Agriculture and the Faculty of the Economy answered the questionnaire with higher environmental responsibility. We assume this is caused by high average age of farmers in Czech Republic who are more aware of the ongoing economical difficulties and perceive differently the risk of higher acquisition costs.

An agent's options in a decision problem are best understood as the decisions that the agent might make. Taking options this way eliminates the gap between an option's adoption and its execution.

The purpose of this study was to investigate the attitudes of decision-makers toward the use of care robots in welfare services. We investigated their knowledge regarding the use of care robots in welfare services as well as their attitudes toward using robots in their own care and in the care of various user groups, for example, children, youths, and older people. We conducted an online survey with a range of Finnish decision-makers as respondents. The respondents were divided into (...) two groups: service actors and research and development actors. The respondents did not regard themselves as having much knowledge about robotics; however, the results showed that the R&D actors had more overall knowledge of the use of robots than the service actors. The R&D actors were found to be more willing to accept a robot as part of their own care as well as part of the care for various user groups. The contribution of this study is a better understanding of the views of the decision-makers who are or will be in charge of the acquisition of technological devices in welfare services. (shrink)

Group decisions raise a number of substantial philosophical and methodological issues. We focus on the goal of the group decision exercise itself. We ask: What should be counted as a good group decision-making result? The right decision might not be accessible to, or please, any of the group members. Conversely, a popular decision can fail to be the correct decision. In this paper we discuss what it means for a decision to be "right" and (...) what components are required in a decision process to produce happy decision-makers. Importantly, we discuss how "right" decisions can produce happy decision-makers, or rather, the conditions under which happy decision-makers and right decisions coincide. In a large range of contexts, we argue for the adoption of formal consensus models to assist in the group decision-making process. In particular, we advocate the formal consensus convergence model of Lehrer and Wagner (1981), because a strong case can be made as to why the underlying algorithm produces a result that should make each of the experts in a group happy. Arguably, this model facilitates true consensus, where the group choice is effectively each person's individual choice. We analyse Lehrer and Wagner's algorithm for reaching consensus on group probabilities/utilities in the context of complex decision-making for conservation biology. While many conservation decisions are driven by a search for objective utility/probability distributions (regarding extinction risks of species and the like), other components of conservation management primarily concern the interests of stakeholders. We conclude with cautionary notes on mandating consensus in decision scenarios for which no fact of the matter exists. For such decision settings alternative types of social choice methods are more appropriate. (shrink)

As medical technology continues to improve, more people will live longer lives with multiple chronic illnesses with increasing cumulative debilitation, including cognitive dysfunction. Combined with the aging of society in most developed countries, an ever-growing number of patients will require surrogate decision-makers. While advance care planning by patients still capable of expressing their preferences about medical interventions and end-of-life care can improve the quality and accuracy of surrogate decisions, this is often not the case, not infrequently leading to demands (...) for ineffective, inappropriate and prolonged interventions. In 1980 LaFollette called for the licensing of prospective parents, basing his argument on the harm they can do to vulnerable people. In this paper, I apply his arguments to surrogate decision-makers for cognitively incapacitated patients, rhetorically suggesting that we require potential surrogates to qualify for this position by demonstrating their ability to make reasonable and rational decisions for others. I employ this theoretical approach to argue that the loose criteria by which we authorize surrogates’ generally unchallenged power should be reconsidered. (shrink)

In the process of decision-making based on conferring with advisors, people are sensitive to advisors’ emotional expressions. An advisor’s expression is considered a type of feedback. The quick detection of motivational or valence significance of feedback has been associated with feedback-related negativity (FRN). In this study, we investigated how decision makers evaluated advice that was distant from the original estimate provided by advisors with different emotional expressions based on behavioural, FRN, and P300 data. The results showed that participants (...) were more likely to modify their initial estimates based on advice from advisors with happy expressions than from advisors with angry expressions, regardless of whether it was near-distance advice or far-distance advice. When facing far-distance advice, FRN amplitudes in angry-expression conditions were significantly larger than in happy-expression conditions. When facing near-distance advice, there was no significant difference in the FRN amplitude between happy- and angry-expression conditions. P300 amplitudes were larger in near-distance conditions than in far-distance conditions. These findings suggest that, as a type of feedback with social information, the advisor’s face will affect the decision maker’s evaluation of the advice, with a happy face of the advisor serving as correct feedback and an angry face serving as incorrect feedback.

The dominant approach to the study of dynamic preference is to generate preference change by manipulating aspects of decision-problem presentation (problem description, task procedure, contextual options). The predisposing approach instead manipulates the decision maker’s mental state while holding problem presentation constant. Three illustrative studies are outlined here. The first modified preferences for ambitious consumption by manipulating subjects’ consumption energy. The second modified preferences for immediate consumption by manipulating subjects’ hedonic resources. The third modified preferences for consumption itself (...) by manipulating subjects’ desire proneness. Whereas framing is thought to affect perception, predisposing apparently can affect tastes and so involves a special kind of preference dynamism. (shrink)

This paper investigates why some companies give to charity and others do not. The study uncovers a strong relationship between the personal attitudes of the charitable decision maker and the firm's giving behavior. This relationship indicates that the human element of personal attitudes may interact and play a very important role in a firm's decision to become involved with philanthropic activities. The study also shows that firms who have a history of giving to charity cite altruistic motives (...) for their behavior. On the other hand, firms that do not give to charity tend to use business reasons to explain their non-involvement. (shrink)

Laypersons serve at critical junctures in the legal process. This article provides an overview of research about layperson roles and draws attention to the research methodologies used in studying them. It also discusses the jury system because, in addition to the fact that this institution has attracted the greatest quantity of empirical research on lay participation in legal processes, the studies have also involved the greatest range of methodological approaches, thus allowing exploration of their various strengths and weaknesses. Research on (...) mixed tribunals, lay magistrates, justices of the peace and other forms of lay participation are also discussed in the article. There are literally hundreds of empirical studies bearing on jury competence and behavior. More systematic research surveying the extent of layperson roles in different cultures and countries is needed and studies of how laypersons actually perform in these roles is crucial. (shrink)

Purpose The manner in which people, businesses and governments perform is changing because of the spread of technology. Digitalization of governments can be considered a necessity as we are now entering the era of the Internet-of-Things. The advantages and disadvantages of electronic governments have been examined in several research studies. This study aims to examine the attitudes of decision-makers towards e-government. The research aims are as follows: to determine the problems related with e-government usage, to establish the factors which (...) decrease the usage of e-government services and to propose recommendations for the effective application of e-government practices. Design/methodology/approach Qualitative research has been used for the study. Participants were chosen by the snowball sampling method, and face-to-face in-depth interviews were conducted with all decision-makers. In-depth interviews are more efficient and enable the acquisition of better qualitative information, in-depth knowledge and statistics, as the distance between the interviewer and interviewee is reduced. Questions asked can be categorized under two sections, where the questions in the first section are related to the decision-maker’s management style/managerial proposition, and in the second section, technological questions are asked in terms of the preferred communication method and the decision-makers’ attitudes towards e-government practices. Findings Decision-makers perceive electronic government to be important, while the level of importance is observed to be different among the decision-makers. Chronic problems exist in many countries, such as nepotism, where the decision-makers have conflicting arguments about e-government and the resulting effect on nepotism. Furthermore, the study also indicates that decision-makers are aware of the importance of mobile government, although they acknowledge that more time is required, as their country is still developing. Electronic voting is also perceived to be important, although the decision-makers believe that security and privacy issues need to be solved before related projects can be initiated. Originality/value This research can be a benchmark study for the decision-makers of small island developing states by means of e-government. The impediments preventing the effective application of e-government practices are also discussed in the study. This study will be useful to highlight the triggers and obstacles for e-government development in the context of a developing country. Internet penetration has increased significantly since the 2000s, and therefore, decision-makers need to consider the shift in citizens’ behaviour, such as the high usage of smartphones and the emergence of the Internet-of-Things.

The purpose of this prospective study was to develop a grounded theory explaining the process that family decision makers use to make care decisions with or for a family member with advanced cancer. Adult surrogate decision makers were recruited for multiple interviews over the patient’s care trajectory: 40 surrogates provided 80 semi-structured interviews. Analysis of these narratives revealed a process of responsive care management that is inclusive of, but not limited to, decision-making roles. Monitoring, buffering, and taking (...) over comprise the three phases of the process. Decision making was embedded within the family member’s broader relational and care responsibilities. (shrink)

Modest difference in individual decisional skills may warrant substantial inequality in power. This claim has been illustrated in Ben Yashar and Nitzan (Economics Letters 174:93–95, 2019), applying the symmetric uncertain dichotomous choice setting and focusing on the skill-dependent (s-d) power of the decision-makers under the optimal decision rule. The same claim is valid when one focuses on the relationship between skill heterogeneity and the distribution of the second type of power, viz., the group members' marginal contribution (mc). This (...) has been shown in Ben Yashar et al. (Journal of Theoretical Politics 33(2):225–235, 2021), where mc has been formally related to s-d power. A preliminary study of the relationship between inequality of the distributions of the two measures has also been presented. The current paper considerably expands this investigation by applying simulations and sheds light on the reason for the increased inequality of the two types of power. Since reward (in terms of status, payment or both) depends on s-d power and mc, inequality of the distribution of rewards depends on the inequality of the two types of power. Comparison of the two types of power inequality is therefore interesting if one wishes to shed light on the role of the two types of power on reward inequality. In particular, the results of the comparison may clarify the effectiveness of the incentives to invest in skills, dependent on the prevailing norms and the institutional characteristics that determine the relationship between rewards and the two types of power. For this reason, the current study focuses on the comparison between inequality of s-d power and marginal contributions showing that, in small (large) groups, on average, the latter is more (less) unequal than the former and both are more unequal than the optimal weights of the decision-makers and much more unequal than their skills. The robustness of these findings is shown by applying alternative symmetric probability distribution functions. Another novel task undertaken in the current study is the sensitivity analysis of inequality of the power measures with respect to changes in the size of the group and the skills of the group members.

An implicit ambiguity in the field of prediction-based decision-making concerns the relation between the concepts of prediction and decision. Much of the literature in the field tends to blur the boundaries between the two concepts and often simply refers to ‘fair prediction’. In this paper, we point out that a differentiation of these concepts is helpful when trying to implement algorithmic fairness. Even if fairness properties are related to the features of the used prediction model, what is more (...) properly called ‘fair’ or ‘unfair’ is a decision system, not a prediction model. This is because fairness is about the consequences on human lives, created by a decision, not by a prediction. In this paper, we clarify the distinction between the concepts of prediction and decision and show the different ways in which these two elements influence the final fairness properties of a prediction-based decision system. As well as discussing this relationship both from a conceptual and a practical point of view, we propose a framework that enables a better understanding and reasoning of the conceptual logic of creating fairness in prediction-based decision-making. In our framework, we specify different roles, namely the ‘prediction-modeler’ and the ‘decision-maker,’ and the information required from each of them for being able to implement fairness of the system. Our framework allows for deriving distinct responsibilities for both roles and discussing some insights related to ethical and legal requirements. Our contribution is twofold. First, we offer a new perspective shifting the focus from an abstract concept of algorithmic fairness to the concrete context-dependent nature of algorithmic decision-making, where different actors exist, can have different goals, and may act independently. In addition, we provide a conceptual framework that can help structure prediction-based decision problems with respect to fairness issues, identify responsibilities, and implement fairness governance mechanisms in real-world scenarios.

ZusammenfassungIm Gesetzentwurf des Bundesrates zur Änderung des Betreuungsrechts ist eine regelhafte Stellvertretung durch Angehörige für zur Entscheidung unfähige Patienten vorgesehen. Mithilfe eines strukturierten Fragebogens wurden die Einstellungen von Tumorpatienten, gesunden Kontrollpersonen, Pflegenden und Ärzten zur Präferenz der zu bevollmächtigenden Personen ermittelt. Nur 10–20% der Befragten haben eine Patientenverfügung verfasst. Als Entscheidungbefugte im Falle akuter Erkrankung werden Angehörige und Ärzte gemeinsam genannt. Als Gesundheitsbevollmächtigte werden Ehepartner/lebenspartner bevorzugt und nichtangehörige Personen nur von einer Minderheit genannt. Die grundsätzliche Bereitschaft, als Gesundheitsbevollmächtigte Verantwortung zu (...) übernehmen, ist hoch, erstreckt sich jedoch überwiegend auf Angehörige. Nur Ärzte sind in bis zu 50% auch für nichtangehörige Personen bereit, als Bevollmächtigte zu entscheiden. Die regelhafte Stellvertretung in Gesundheitsfragen durch Angehörige entspricht den Wünschen der Mehrheit von Tumorpatienten, gesunden Vergleichspersonen und medizinischem Personal. (shrink)

Berger (2019) argues effectively that “representativeness is more aptly understood as a variable that is multidimensional and continuous based on relational moral authority,” and also makes some useful suggestions about how taking this observation seriously might require changes in current patterns of practice regarding surrogates. But the essay raises additional important questions about how the Best Interest Standard (BIS) should be used among unrepresented patients and other patients as well because many surrogates besides those who “have no actionable knowledge of (...) a patient’s preferences” find themselves in positions in which they need to determine, with the physician, what is in the patient’s best interests. In this commentary, we therefore provide support for the ethical superiority of BIS judgments made by a multi-stakeholder process (rather than solo decision-makers), and sketch a process by which such judgments might be made.

I consider two puzzles in which an agent undergoes a sequence of decision problems. In both cases it is possible to respond rationally to any given problem yet it is impossible to respond rationally to every problem in the sequence, even though the choices are independent. In particular, although it might be a requirement of rationality that one must respond in a certain way at each point in the sequence, it seems it cannot be a requirement to respond as (...) such at every point for that would be to require the impossible.

Not much has been written on the foreign assistance policy of Belgium, but work that focuses on it singly or in comparison with other cases tends to charge that Belgium lacks a coherent foreign assistance policy. This study examines the rhetoric of Belgian decision makers and the policy behavior of the state, utilizing a framework of four national role conception profiles, each bringing together a set of perceptions regarding the role decision makers perceive their state to play in (...) this issue area.Parliamentary debates for the period 1975-90 are coded for mention of themes associated with these profiles, white OECD data regarding the foreign aid expenditures for the same period provide insight into the policy behavior. It concludes that Belgian decision makers do not perceive foreign assistance as a separate issue area, but as inextricably linked with foreign policy. (shrink)

A first principle in ethics consultation is that reasoning is essential. A second principle is that the religious and cultural views of patients and their surrogates are usually respected. What can be done when these principles collide—when patients or surrogates have religious or cultural views and beliefs that clinicians find unreasonable or even offensive? Mediation may provide some approaches to assist us in providing the most ethically appropriate assistance.

Pascal’s Wager does not exist in a Platonic world of possible gods, abstract probabilities and arbitrary payoffs. Real decision-makers, such as Pascal’s “man of the world” of 1660, face a range of religious options they take to be serious, with fixed probabilities grounded in their evidence, and with utilities that are fixed quantities in actual minds. The many ingenious objections to the Wager dreamed up by philosophers do not apply in such a real decision matrix. In the situation (...) Pascal addresses, the Wager is a good bet. In the situation of a modern Western intellectual, the reasoning of the Wager is still powerful, though the range of options and the actions indicated are not the same as in Pascal’s day. (shrink)

Prior research indicates that time perspective (TP; views of past, present and future) is related to decision making style. By contrast, no prior study considered relations between time perspective and decision-making competence. We therefore investigated associations between dimensions of the Swedish Zimbardo Time Perspective Inventory (S-ZTPI) and performance on the Adult Decision-Making Competence (A-DMC) battery in a sample of older adults (60-90 years, N = 346). A structural equation model involving four A-DMC components as indicators of a (...) general DMC factor and the six TP dimensions as the predictors revealed a significant negative association between the Present Fatalistic dimension and DMC. Given that age-related differences were apparent in DMC and that Present Fatalistic orientation increased with age, we tested a model by which the age-related differences in DMC were mediated by age-related differences in Present Fatalistic attitudes and in working memory. The results were consistent with full mediation of the age effects, with Present Fatalistic and working memory jointly accounting for a substantial amount of the variance in DMC (51%). The finding that DMC among older adults, in particular more cognitively demanding aspects such as applying decision rules, can be undermined by increased present fatalistic attitudes and declines in working memory is discussed in terms of theoretical frameworks highlighting the contribution of both motivational and cognitive factors to effective decision making.

We aim to establish the following claim: other factors held constant, the relative weights of the epistemic burdens of competing treatment options serve to determine the options that patient surrogates pursue. Simply put, surrogates confront an incentive, ceteris paribus, to pursue treatment options with respect to which their knowledge is most adequate to the requirements of the case. Regardless of what the patient would choose, options that require more knowledge than the surrogate possesses (or is likely to learn) will either (...) be neglected altogether or deeply discounted in the surrogate’s incentive structure. We establish this claim by arguing that the relation between epistemic burdens and incentives in decision-making is a general feature of surrogate decision-making. After establishing the claim, we draw out some of the implications for surrogate decision-making in medicine and offer philosophical and psychological explanations of the phenomenon. (shrink)

Background Empirical studies of surrogate decision-making tend to assume that surrogates should make only a 'substituted judgement'—that is, judge what the patient would want if they were mentally competent. Objectives To explore what people want in a surrogate decision-maker whom they themselves select and to test the assumption that people want their chosen surrogate to make only a substituted judgement. Methods 30 undergraduate students were recruited. They were presented with a hypothetical scenario about their expected loss of (...) mental capacity in the future and asked to answer some questions about their choice of surrogate. These data were analysed qualitatively using thematic content analysis. Results Most respondents talked about choosing someone who was caring and competent in certain ways, giving interesting evidence for their judgements. Surprisingly few highlighted how well they thought their chosen surrogate knew their preferences and would be able to make a substituted judgement. Moreover, few specified that their chosen surrogate had similar attitudes and values to their own and so would make a similar decision to theirs in the circumstances presented. Some respondents also referred to the social role of their chosen surrogate or the social dynamics of their situation which influenced their choices, as well as to ideas of reciprocity and characteristics of honesty and loyalty. Conclusion In the event that they lose mental capacity, many people will not select a surrogate to decide about medical treatments on their behalf solely on the basis that they expect their surrogate to make a substituted judgement.

This paper is based on a five-year study of the ethical principles considered by executives, middle managers, and students as appropriate guidelines for making decisions. Out of the fourteen principles surveyed, nine seem to be standards that can be applied with no further thought or research required by the decision maker. The other six principles may suggest decisions makers need clearer guidelines as to what to do or what not to do when faced with an ethical dilemma that (...) exists outside defined systems of corporate ethics.

Research based on the behavioral theory of the firm (BTOF) argues that firms will actively adopt strategic actions to respond to performance that falls below aspirations, that is performance shortfalls. However, most previous studies have focused on market-related strategic actions, paying less attention to the impact of performance shortfalls on non-market-related strategic actions, especially corporate social responsibility (CSR) and corporate social irresponsibility (CSI). In this study, we propose that firms facing performance shortfalls are likely to reduce CSR levels and increase (...) CSI levels. In addition, we also propose that board characteristics (board size, board age and board tenure) have a significant moderating effect on the above relationship. Empirical analyses based on an unbalanced panel data of China's listed firms from 2010 to 2018 show that our arguments are largely supported. (shrink)

This research investigates managerial value orientations using the Rokeach Value Survey to assess the importance managers assign to various values. While prior work and select organizational theory posit that MVO will not change over time, the data are analyzed to determine if the MVO of mid- to upper-level managers, the key decision-makers in most organizations, has remained generally the same or has changed from one generation to another. The results show that the MVO of managers from 1990 is significantly (...) different than the MVO of managers today. The greatest difference lies in the MVO area of competence versus moral values, with more managers emphasizing a moral value orientation than previously. Therefore, the data indicate there is a noticeable shift in MVO over the past 20+ years. The implications of the results reported are discussed, along with suggestions for future managerial values research. (shrink)

A hybrid preference framework is proposed for strategic conflict analysis to integrate preference strength and preference uncertainty into the paradigm of the graph model for conflict resolution (GMCR) under multiple decision makers. This structure offers decision makers a more flexible mechanism for preference expression, which can include strong or mild preference of one state or scenario over another, as well as equal preference. In addition, preference between two states can be uncertain. The result is a preference framework that (...) is more general than existing models which consider preference strength and preference uncertainty separately. Within the hybrid preference structure, four kinds of stability are defined as solution concepts and a post-stability analysis, called status quo analysis, which can be used to track the evolution of a given conflict. Algorithms are provided for implementing the key inputs of stability analysis and status quo analysis within the extended preference structure. The new stability concepts under the hybrid preference structure can be used to model complex strategic conflicts arising in practical applications, and can provide new insights for the conflicts. The method is illustrated using the conflict over proposed bulk water exports from Lake Gisborne in Newfoundland, Canada. (shrink)

An expected utility model of individual choice is formulated which allows the decision maker to specify his available actions in the form of controls (partial contingency plans) and to simultaneously choose goals and controls in end-mean pairs. It is shown that the Savage expected utility model, the Marschak- Radner team model, the Bayesian statistical decision model, and the standard optimal control model can be viewed as special cases of this goal-control expected utility model.

The laser chaos decision maker has been demonstrated to enable ultra-high-speed solutions of multiarmed bandit problems or decision-making in the GHz order. However, the underlying mechanisms are not well understood. In this paper, we analyze the chaotic dynamics inherent in experimentally observed laser chaos time series via surrogate data and further accelerate the decision-making performance via parameter optimization. We first evaluate the negative autocorrelation in a chaotic time series and its impact on decision-making detail. Then, (...) we analyze the decision-making ability using three different surrogate chaos time series to examine the underlying mechanism. We clarify that the negative autocorrelation of laser chaos improves decision-making and that the amplitude distribution of the original laser chaos time series is not optimal. Hence, we introduce a new parameter for adjusting the amplitude distribution of the laser chaos to enhance the decision-making performance. This study provides a new insight into exploiting the supremacy of chaotic dynamics in artificially constructed intelligent systems. (shrink)

This note completes the main result of Zimper, by showing that additional conditions are needed in order the law of iterated expectations to hold true for Choquet decision makers. Due to the comonotonic additivity of Choquet expectations, the equation E[f, ν] = E[E[f, ν], ν], is valid only when the act f is comonotonic with its dynamic form, that we name “conditional certainty equivalent act”.

This paper argues that Charlie Gard’s parents should have been the decision-makers about their son’s best interests and that determination of Charlie’s best interests depended on a moral decision about which horn of a profound moral dilemma to choose. Charlie’s parents chose one horn of that moral dilemma and the courts, like Charlie Gard’s doctors, chose the other horn. Contrary to the first UK court’s assertion, supported by all the higher courts that considered it, that its judgement was (...) ‘objective’, this paper argues that the judgement was not and could not be ‘objective’ in the sense of objectively correct but was instead a value judgement based on the judge’s choice of one horn of the moral dilemma. While that horn was morally justified so too was the horn chosen by the parents. The court could and should have avoided depriving the parents of their normal moral and legal right and responsibility to decide on their child’s best interests. Instead, this paper argues that the court should have acknowledged the lawfulness of both horns of the moral dilemma and added to its judgement that Charlie Gard’s doctors were not legally obliged to provide treatment that they believed to be against their patient’s best interests the additional judgement that Charlie’s parents could lawfully transfer his care to other doctors prepared to offer the infant a trial of the experimental treatment requested by his parents.
