A transformative decision rule alters the representation of a decision problem, either by changing the set of alternative acts or the set of states of the world taken into consideration, or by modifying the probability or value assignments. A set of transformative decision rules is order-independent in case the order in which the rules are applied is irrelevant. The main result of this paper is an axiomatic characterization of order-independent transformative decision rules, based on a single axiom. It is shown (...) that the proposed axiomatization resolves a problem observed by Teddy Seidenfeld in a previous axiomatization by Peterson. (shrink)

This longitudinal study investigated the capability of various positive psychological resources to directly or indirectly protect specific well-being outcomes and moderate the effects on well-being of health and economic threats in a lockdown situation during the 2020 health crisis in France. At the beginning of lockdown, participants completed self-assessment questionnaires to document their initial level of well-being and state of nine different well-established psychological resources, measured as traits: optimism, hope, self-efficacy, gratitude toward the world, self-transcendence, wisdom, gratitude of being, peaceful (...) disengagement, and acceptance. Three weeks later, a weekly follow-up was started to record changes in well-being and reported threats for a duration of 5 weeks. Results show that psychological resources efficiently protected well-being in a variety of ways: they buffered the adverse effects of reported threats to health and wealth, increased the well-being averages, and reduced the decline in well-being over time. More specifically, emotional well-being was positively predicted by hope, gratitude of being, and, to a lesser level, by acceptance; psychological well-being by self-efficacy, personal wisdom, and gratitude of being; social well-being only by gratitude toward the world; and inner well-being by optimism, gratitude of being, and acceptance. The study emphasizes the importance of cultivating psychological resources in ordinary times to protect individuals' well-being when difficult and extraordinary circumstances occur. It also offers clues to the kind of resources one may want to develop. (shrink)

Iowa Gambling Task (IGT) is one of the most widely used tools to assess economic decision-making. However, the research tradition on aging and the Iowa Gambling Task (IGT) has been mainly focused on the overall performance of older adults in relation to younger or clinical groups, remaining unclear whether older adults are capable of learning along the task. We conducted a meta-analysis to examine older adults’ decision-making on the IGT, to test the effects of aging on reversal learning (45 studies) (...) and to provide normative data on total and block net scores (55 studies). From the accumulated empirical evidence, we found an average total net score of 7.55 (± 25.9). We also observed a significant reversal learning effect along the blocks of the IGT, indicating that older adults inhibit the prepotent response towards immediately attractive options associated with high losses, in favor of initially less attractive options associated with long-run profit. During block 1, decisions of older adults led to a negative gambling net score, reflecting the expected initial pattern of risk-taking. However, the shift towards more safe options occurred between block 2 (small-to-medium effect size) and blocks 3, 4, 5 (medium-to-large effect size). These main findings highlight that older adults are able to move from the initial uncertainty, when the possible outcomes are unknown, to decisions based on risk, when the outcomes are learned and may be used to guide future adaptive decision-making.

Decision-making competence reflects individual differences in the susceptibility to decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules). Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus on intermediate mechanisms that may impact real-world decisions, and, in particular, those implicated by normative models. Here we test the associations between measures of youth decision-making competence (Y-DMC) and one such mechanism, (...) the degree to which individuals make choices consistent with maximizing expected value (EV). Using a task involving hypothetical gambles, we find that greater EV sensitivity is associated with greater Y-DMC. Higher Y-DMC scores are associated with (a) choosing risky options when expected value favors those options and (b) avoiding risky options when expected value favors a certain option. This relationship is stronger for gambles that involved potential losses. The results suggest that Y-DMC captures decision processes consistent with standard normative evaluations of risky decisions.

Experimental studies suggest that individuals exhibit more risk aversion in choices among prospects when the payment and resolution of uncertainty are immediate relative to when it is delayed. This leads to preference reversals that cannot be attributed to discounting. When data suggest that utility is time-independent, probability weighting functions, such as those used to model prospect theory preferences, can accommodate such reversals. We propose a simple descriptive model with a two-parameter probability weighting function where one of these parameters depends on (...) the time at which a prospect is resolved. The time-dependent parameter is responsible for the curvature of the probability weighting function and is regarded as an index of sensitivity towards changes in probabilities. We provide conditions that characterize increased sensitivity towards more distant probabilities; this can account for the observed relatively less risk aversion towards delayed prospects. In our framework, the discount function is unrestricted, such that the model is compatible with empirical findings of non-constant discounting. In a simple application to bargaining we illustrate when it is advantageous for an individual to advance or delay the bargaining resolution time if an opponent displays increased sensitivity towards probability changes with delay.

When forecasting events, multiple types of uncertainty are often inherently present in the modeling process. Various uncertainty typologies exist, and each type of uncertainty has different implications a scientist might want to convey. In this work, we focus on one type of distinction betweendirect quantitative uncertaintyandindirect qualitative uncertainty. Direct quantitative uncertainty describes uncertainty about facts, numbers, and hypotheses that can be communicated in absolute quantitative forms such as probability distributions or confidence intervals. Indirect qualitative uncertainty describes the quality of knowledge (...) concerning how effectively facts, numbers, or hypotheses represent reality, such as evidence confidence scales proposed by the Intergovernmental Panel on Climate Change. A large body of research demonstrates that both experts and novices have difficulty reasoning with quantitative uncertainty, and visualizations of uncertainty can help with such traditionally challenging concepts. However, the question of if, and how, people may reason with multiple types of uncertainty associated with a forecast remains largely unexplored. In this series of studies, we seek to understand if individuals can integrate indirect uncertainty about how “good” a model is (operationalized as a qualitative expression of forecaster confidence) with quantified uncertainty in a prediction (operationalized as a quantile dotplot visualization of a predicted distribution). Our first study results suggest that participants utilize both direct quantitative uncertainty and indirect qualitative uncertainty when conveyed as quantile dotplots and forecaster confidence. In manipulations where forecasters were less sure about their prediction, participants made more conservative judgments. In our second study, we varied the amount of quantified uncertainty (in the form of the SD of the visualized distributions) to examine how participants’ decisions changed under different combinations of quantified uncertainty (variance) and qualitative uncertainty (low, medium, and high forecaster confidence). The second study results suggest that participants updated their judgments in the direction predicted by both qualitative confidence information (e.g., becoming more conservative when the forecaster confidence is low) and quantitative uncertainty (e.g., becoming more conservative when the variance is increased). Based on the findings from both experiments, we recommend that forecasters present qualitative expressions of model confidence whenever possible alongside quantified uncertainty. (shrink)

If neuroscience is to contribute to economics, it will do so by the way of psychology. Neural data can and do lead to better psychological theories, and psychological insights can and do lead to better economic models. Hence, neuroscience can in principle contribute to economics. Whether it actually will do so is an empirical question and the jury is still out. Economics currently faces theoretical and empirical challenges analogous to those faced by physics at the turn of the twentieth century (...) and ultimately addressed by quantum theory. If will emerge in the coming decades, it may well be founded on such concepts as cognitive processes and brain activity. (shrink)

Despite the conclusions from the contemporary philosophy of science, many economists cherish the ideal of positive science. Therefore, value-free economics is still the central paradigm in economics. The first aim of the paper is to investigate economics' axiomatic assumptions from an epistemological perspective. The critical analysis of the literature shows that the positive-normative dichotomy is exaggerated. Moreover, value-free economics is based on normative foundations that have a negative impact on individuals and society. The paper's second aim is to show that (...) economics' normativity is not a problem because the discussion concerning values is possible and unavoidable. In this context, Weber and other methodologists are investigated. The conclusion of the paper is that science can thrive without strict methodological rules thanks to institutional mechanisms. Therefore, economists could learn from artists who accept the world without absolute rules. This perspective opens the possibility for methodological pluralism and normative approaches. (shrink)

Should fear guide our actions and governments’ political decisions? A leitmotiv of common sense is that emotions are tricky, they blur our rational capacity of estimating utilities in order to plan action and thus they should be banned from any account of our rational expectations. In this paper I argue that an “heuristic of fear” is the appropriate attitude to adopt in order to cope with extreme risks. I thus defend the Precautionary Principle against the criticism put forward by Cass (...) Sunstein and other authors on the basis of a new analysis of extreme risks or “ruin-problems”. (shrink)

Environmental problems have an ethical dimension. They are not just about the efficient use of resources. Justice in the distribution of environmental goods and burdens, fairness in the processes of environmental decision-making, the moral claims of future generations and non-humans, these and other ethical values inform the responses of citizens to environmental problems. How can these concerns enter into good policy-making processes?Two expert-based approaches are commonly advocated for incorporating ethical values into environmental decision-making. One is an 'economic capture' approach, according (...) to which existing economic methods can be successfully extended to include ethical concerns. For example, stated preference methods, especially contingent valuation, have been developed to try and capture ethical responses as 'non-use values' of the environment, in particular 'existence values'. The other is a 'moral expert' approach which confines economic methods to the analysis of welfare gains, and assumes committees of ethical experts will complement economic expertise.Both approaches face problems in terms of addressing many widely held ethical values about the environment. Furthermore, both face problems concerning the democratic legitimacy of their procedures. How can policy-making be made responsive to different ethical values? What role is there for new deliberative and participatory methods? How far do existing decision-making institutions have the capacities to incorporate different modes of articulating environmental values?This policy brief examines the limitations of current attempts to capture ethical values within existing economic instruments and considers how these limitations might be overcome. Section 1 examines the assumptions that standard economic theory makes about individuals when they express values and make choices about the environment. The current models of agents that inform policy-making are seen to be ill-suited to incorporating the ethical responses of agents and this reveals some of the policy failures that may result. Section 2 shows how the physical and social properties of many environmental goods prevent their being treated as commodities. Section 3 considers the problems surrounding conceptions of fairness and legitimacy in processes for environmental valuation. Section 4 raises questions concerning the capacities of policy-making institutions to take cognisance of the results of different methods for articulating environmental values. (shrink)

Over recent years, a number of behavioural economic-informed policy frameworks have been developed, ranging from soft and hard forms of paternalism, to regulation against negative externalities, the so-called nudge, shove and budge approaches. This article considers these different frameworks as applied to some of the challenges posed by the social care needs of contemporary societies. It is argued that all of the frameworks are worthy of serious consideration in this policy domain, in that they offer food for thought on how (...) financial contributions to pay for social care might be increased, and how the quality of social care provision may be improved given available resources.

While agreeing with the main conclusion of Dominic Wilkinson and colleagues (Wilkinson, Butcherine, and Savulescu 2019), namely, that there is no moral difference between treatment withholding and withdrawal as such, we wish to criticize their approach on the basis that it treats the widespread acceptance of withdrawal aversion (WA) as a cognitive bias. Wilkinson and colleagues understand WA as “a nonrational preference for withholding (WH) treatment over withdrawal (WD) of treatment” (22). They treat WA as a manifestation of loss aversion (...) and refer to Kahneman and colleagues (1991), which defined this effect as follows: “the disutility of giving up an object is greater that the utility associated with acquiring it” (194). In a previous work, Wilkinson and Savulescu understood nonequivalence between treatment withholding and withdrawal as a reflection of slightly different, although related, phenomena: status quo bias or omission bias (Wilkinson and Savulescu 2012, 130–131). In neither of these two papers do they describe precisely the relation between these well-known psychological effects and WA, nor do they explain why they treat these effects as examples of nonrational preferences, despite the fact that these issues have been the subject of wide-ranging discussions on the intersection of psychology, economy, and philosophy.

I investigate whether degreed beliefs are able to play the predictive, explanatory, and modeling roles that they are frequently taken to play. The investigation focuses on evidence—both from sources familiar in epistemology as well as recent work in behavioral economics and cognitive psychology—of variability in agents' apparent degrees of belief. Although such variability has been noticed before, there has been little philosophical discussion of its breadth or of the psychological mechanisms underlying it. Once these are appreciated, the inadequacy of degrees (...) of belief becomes clear. I offer a theoretical alternative to degrees of belief, what I call the filter theory. (shrink)

In two experimental studies we explore to what extent the general effects of positive and negative framing also apply to positive and negative persuasion. Our results reveal that negative persuasion induces substantially higher levels of skepticism and awareness of being subjected to a persuasion attempt. Furthermore, we demonstrate that in positive persuasion, more claims lead to stronger persuasion, while in negative persuasion, the numerosity of claims carries no significant effect. We interpret this finding along the lines of a satiety-model of (...) persuasion. Finally, using diluted, or low strength claims in a persuasion attempt, we reveal a significant interaction between dispositional reactance and dilution of claims on persuasion knowledge. The interaction states that diluted claims increase the awareness of being subjected to a persuasion attempt, but only for those with a high dispositional level of reactance. (shrink)

When faced with the threat of negative reputation spillover from an alliance partner accused of environmental misconduct, the focal firm must decide whether to adopt a supportive or non-supportive response. We argue that this decision denotes a commitment escalation dilemma, but that factors previously found to increase escalation tendencies lead to de-escalation in our crisis contagion context. Specifically, we derive four hypotheses from this reverse effect proposition, and test these using a policy-capturing survey targeting Norwegian CEOs. We found that firms (...) are more likely to select an adversary response when the alliance is of high strategic importance and has high termination costs. Conversely, firms are more likely to select an advocacy response when the alliance is of low strategic importance and has low termination costs and when the CEO was not involved in the formation of the alliance. Overall, our study answers a call for a more nuanced understanding of commitment escalation and the theory’s boundary conditions by introducing reputation spillover crisis as a contextual influencer of escalation behavior. It also extends the reputation literature and provides new evidence that reputation concerns can instigate ethical decision-making. (shrink)

Probability transformation functions were introduced into modelsof behavior toward risk to allow them to accommodate violations of the expected utility hypothesis.This paper examines the shape of the probability transformation function, its interpretation asoptimism or pessimism, and how the ranking of outcomes becomes important when probability transformationsare used. It also explores two behavioral implications: the overweighting of unlikely, extremeoutcomes, and intertia around certainty. Finally, the rationality of transforming the probabilitydistribution is discussed.

Lara Buchak argues for a version of rank-weighted utilitarianism that assigns greater weight to the interests of the worse off. She argues that our distributive principles should be derived from the preferences of rational individuals behind a veil of ignorance, who ought to be risk averse. I argue that Buchak’s appeal to the veil of ignorance leads to a particular way of extending rank-weighted utilitarianism to the evaluation of uncertain prospects. This method recommends choices that violate the unanimous preferences of (...) rational individuals and choices that guarantee worse distributions. These results, I suggest, undermine Buchak’s argument for rank-weighted utilitarianism. (shrink)

This paper presents a critical reflection on dynamic consistency as commonly used in economics and decision theory, and on the difficulty to test it experimentally. It distinguishes between the uses of the term dynamic consistency in order to characterize two different properties: the first accounts for the neutrality of individual preferences towards the timing of resolution of uncertainty whereas the second guarantees that a strategy chosen at the beginning of a sequential decision problem is immune to any reevaluation and will (...) effectively be implemented from then on in the decision problem. Although these two properties are equivalent under expected utility, this is not the case under non-EU. Building on the possible characteristics of individual dynamic preferences under risk, this paper proposes a conceptual categorization, that is experimentally testable, of possible sequential decision making behaviors of non-EU maximizers.

We propose a triple test to evaluate the usefulness of behavioral economics models for public health policy. Test 1 is whether the model provides reasonably new insights. Test 2 is on whether these have been properly applied to policy settings. Test 3 is whether they are corroborated by evidence. We exemplify by considering the cases of social interactions models, self-control models and, in relation to health message framing, prospect theory. Out of these sets of models, only a correctly applied prospect (...) theory fully passes the tests at present. Specifically, in broad agreement with the evidence, a gain frame has positive implications for welfare encourages disease prevention activity, though this does not apply if the perceived probability of the bad health outcome is large enough. We see our tests as being useful to identify how much health policy weight policy makers should assign to specific behavioral economic models; they are also useful to verify what next steps would be most useful in further research.

ABSTRACT Setting specific, challenging goals motivates employees to exert greater effort in their jobs. However, goal-setting may have unintended consequences of also motivating unethical behavior. The present study explores these consequences in the context of other features of goal-setting in organizations, how goals are framed and rewarded, to determine the tradeoff between performance and ethical behavior. Undergraduate students were incentivized to complete math problems using different outcome frames and incentive structures and were also provided an opportunity to cheat. Findings demonstrate (...) that when goals rewarded with piece-rate incentives are framed as a loss, performance increased, though cheating behavior increased as well. (shrink)

This article assesses two major conceptual arguments against theories of choice.The first argument concerns the circularity of belief-desire psychology, on which decision theory is based. The second argument concerns the normativity arising from the concept of rationality. Each argument is evaluated against experimental practice in economics and psychology, and it is concluded that both arguments fail to establish their skeptical conclusion that there can be no science of intentional human actions.

In response to calls for more research on how to prevent or detect fraud (ACAP, Final Report of the Advisory Committee on the Auditing Profession, United States Department of the Treasury, Washington, DC, 2008 ; AICPA, SAS No. 99: Consideration of Fraud in a Financial Statement Audit, New York, NY, 2002 ; Carcello et al., Working Paper, University of Tennessee, Bentley University and Kennesaw State University, 2008 ; Wells, Journal of Accountancy, 2004 ), we develop a framework that identifies three (...) psychological pathways to fraud, supported by multiple theories relating to moral intuition and disengagement, rationalization, and the role played by negative affect. The purpose of developing the framework is twofold: (1) to draw attention to important yet under-researched aspects of ethical decision-making, and (2) to increase our understanding of the psychology of committing fraud. Our framework builds on the existing fraud triangle (PCAOB, Consideration of fraud in a financial statement audit. AU Section 316, www.pcaobus.org , 2005 ) which is used by auditors to assess fraud risk. The fraud triangle is composed of three factors that, together, predict the likelihood of fraud within an organization: opportunity, incentive/pressure, and attitude/rationalization. We find that, when faced with the opportunity and incentive/pressure, there are three psychological pathways to fraud nestled within attitude/rationalization: (1) lack of awareness, (2) intuition coupled with rationalization, and (3) reasoning. These distinctions are important for fraud prevention because each of these paths is driven by a different psychological mechanism. This framework is useful in a number of ways. First, it identifies certain insidious situational factors in which individuals commit fraud without recognizing it. Second, it extends our knowledge of rationalization by theorizing that individuals use rationalization to avoid or reduce the negative affect that accompanies performing an unethical behavior. Negative affect is important because individuals wish to avoid it. Third, it identifies several other methods fraudsters use to reduce negative affect, each of which could serve as potential “psychological red flags” and helps predict future fraudulent behavior. Finally, our framework can be used as a theoretical foundation to explore several interventions designed to prevent fraud. (shrink)

Prior research suggests that Corporate Environmental Performance enables businesses to build strong corporate image and reputation, thus leading to improved firm financial performance. However, studies relating to the relationship between CEP and firm risk are scarce.

Results of the Ordinary Least Squares regression with fixed effects provide strong evidence that environmental performance is negatively associated with firm volatility and firm (...) downside risk. The results are robust after controlling for moderating effects such as financial, institutional and environmental management. (shrink)

Economics bases the choice theory on the mental experiment that introduces the choice correspondence, which associates to every set of possible actions the subset of preferred actions. If some conditions are satisfied, then the choice correspondence implies a binary preference ordering on actions and an ordinal utility function. This approach applies both to decisions under certainty and decisions under uncertainty. The preference ordering depends on the consequence of actions. Under certainty, there is only one consequence to every action, while, under (...) uncertainty, many consequences are possible, associated with the states of the world. These consequences are represented by the action itself, the states of the world, and the corresponding outcomes. Current theories consider only outcomes, but some theories include state dependent preference. Preference for the action itself is not considered, but it might be relevant. The rationality of the theory is a different question from the rationality of the decision-maker. Moreover, the rationality of the theory may imply the rationality of a preference ordering, but this does not require the rationality of the decision-maker. It is only assumed that he/she behaves according to the calculation made by the theorist. The rationality of the preference ordering requires the rationality of the preference on outcomes, of the expectations on the events, and of their connection with the preference ordering on actions. The normative relevance of rational preferences is removed by the introduction of many alternative rational theories, which justify contrasting behaviors in identical situations. (shrink)

When making a decision, humans consider two types of information: information they have acquired through their prior experience of the world, and further information they gather to support the decision in question. Here, we present evidence that data from search engines such as Google can help us model both sources of information. We show that statistics from search engines on the frequency of content on the Internet can help us estimate the statistical structure of prior experience; and, specifically, we outline (...) how such statistics can inform psychological theories concerning the valuation of human lives, or choices involving delayed outcomes. Turning to information gathering, we show that search query data might help measure human information gathering, and it may predict subsequent decisions. Such data enable us to compare information gathered across nations, where analyses suggest, for example, a greater focus on the future in countries with a higher per capita GDP. We conclude that search engine data constitute a valuable new resource for cognitive scientists, offering a fascinating new tool for understanding the human decision-making process. (shrink)

Social scientists have long assumed that religion – and more specifically religious rituals – promotes cooperation. It has also been claimed that ritual plays an essential role in enhancing prosociality and cooperation. In this study, using a controlled laboratory experiment, we investigate if a conspicuous and recurrent feature of collective ritualized behaviour, goal-demotion, promotes lasting cooperation. We report that goal-directed collective behaviour is more efficient than goal-demoted behaviour for motivating participants to engage in ulterior cooperation. Plausible interpretations of the data (...) and of the mechanisms involved are discussed. (shrink)

Introduction Outbreaks of serious communicable infectious diseases remain a major global medical problem and force healthcare workers to make hard choices with limited information, resources and time. While information regarding physicians’ opinions about such dilemmas is available, research discussing students’ opinions is more limited. Methods Medical students were surveyed about their willingness to perform medical procedures on patients with communicable diseases as students and as physicians. Students were asked about their opinions regarding the duty to treat in such cases. Results (...) 74% of respondents felt that by deciding to enter medical school they were morally obliged to treat any patient despite the risks. Students’ willingness to treat as physicians is significantly higher than their willingness to treat as students. HIV was significantly the most tolerated disease with respect to performing mouth to mouth resuscitation. Among preclinical students, we found that willingness to treat during the later years is significantly greater than during the earlier years. Among clinical students, the opposite was observed. Discussion Students’ greater willingness to treat as physicians is mostly attributed to perceptions of higher obligations as a qualified doctor. There is greater but not total willingness to perform resuscitation on patients with HIV relative to other diseases. The increased willingness of preclinical students and the decreased willingness of clinical students both emphasise the importance of patient--physician communication and ethics studies during medical school.

Care is more than dispensing pills or cleaning beds. It is about responding to the entire patient. What is called “bedside manner” in medical personnel is a quality of treating the patient not as a mechanism but as a being—much like the caregiver—with desires, ideas, dreams, aspirations, and the gamut of mental and emotional character. As automata, answering an increasing functional need in care, are designed to enact care, the pressure is on their becoming more humanlike to carry out the (...) function more effectively. The question becomes not merely whether the care automaton can effect good bedside manner but whether the patient’s response is not feeling deceived by the humanlikeness. It seems the device must be designed either to effect explicit mere human-“likeness,” thus likely undermining its bedside-manner potential, or to fool the patient completely. Neither option is attractive. This article examines the social problems of designing maximally humanlike care automata and how problems may start to erode the human rights of users/patients. The article then investigates the alternatives for dealing with this problem, whether by industrial and professional self-regulation or public-policy initiatives. It then frames the problem in the broader historical perspective in terms of previous bans, moratoria, and other means of control of hazardous and potentially rights-violating techniques and materials.

BackgroundHealth behavior change is among the top recommendations for improving health of patients with lifestyle-related chronic diseases. An array of behavior change techniques have been developed to support behavior change initiation and maintenance. These BCTs often show limited success when they are not informed by theory, leading to a mismatch between the intention of the BCT and patients’ needs or expectations. Previous studies have identified a number of resources which patients may require to initiate and maintain health behavior change. Indeed, (...) not yet well established is how BCTs address these resources, i.e., the functional mechanisms of BCTs.PurposeProvide a theoretical framework of the functional mechanisms of BCTs for developing and implementing successful interventions for health behavior change.MethodsConceptual review, including literature analysis and synthesis as well as conceptualization of a new model based on the synthesis.ResultsThrough the integration of dual-process models as well as reward and motivation proceeding, i.e., affective, emotional, or intuitive neurobiological cues, into the rational framework of rather linear cognitive or task-related decision progress, we categorize previously identified resources into three distinct sets: external, internal reflective, and internal affective resources. Based on this triad, we classify BCTs according to their functional mechanisms into facilitating, boosting, and nudging. Consequently, we present a simplified Behavior Change Resource Model that is centered on patients’ resources.ConclusionThe model can be applied to develop health behavior change interventions, which promote engagement and empowerment. Future studies should aim at testing the applicability and practicality of the BCRM. (shrink)

We argue in favor of the adaptive value of acceptance and that it deserves a definite status within the 'positive paradigm'. Acceptance currently suffers from ambiguous connotations because of its lack of optimistic biases and its similarity to resignation. We endeavor to show that acceptance and resignation are distinct attitudes by exploring their relationships with various phenomena-frustration, disappointment, expectation, positive thinking, replanning, and accuracy. The resulting distinguishing features of acceptance-thriving versus returning to baseline; realistic optimism versus hopelessness; persistence and flexible (...) replanning versus disengagement-are crucial for adaptive coping, and appear to be in keeping with the positive paradigm.

Deep brain stimulation is part of state-of-the-art treatment for medically refractory Parkinson’s disease, essential tremor or primary dystonia. However, there are multiple movement disorders that present after a static brain lesion and that are frequently refractory to medical treatment. Using Holmes tremor as an example, we discuss the effectiveness of currently available treatments and, performing simulations using a Markov Chain approach, propose that DBS with iterative parameter optimization is expected to be more effective than an approach based on sequential trials (...) of pharmacological agents. Since, in DBS studies for HT, the thalamus is a frequently chosen target, using data from previous studies of lesion connectivity mapping in HT, we compared the connectivity of thalamic and non-thalamic targets with a proxy of the HT network, and found a significantly higher connectivity of thalamic DBS targets in HT. The understanding of brain networks provided by analysis of functional connectivity may thus provide an informed framework for proper surgical targeting of individual patients. Based on these findings, we argue that there is an ethical imperative to at least consider surgical options in patients with uncommon movement disorders, while simultaneously providing consistent information regarding the expected effectiveness and risks, even in a scenario of surgical-risk aversion. An approach based on n-of-1 DBS trials may ultimately significantly improve outcomes while informing on optimal therapeutic targets and parameter settings for HT and other disabling and rare movement disorders.

A central point of debate over environmental policies concerns how future costs and benefits should be assessed. The most commonly used method for assessing the value of future costs and benefits is economic discounting. One often-cited justification for discounting is uncertainty. More specifically, it is risk aversion coupled with the expectation that future prospects are more risky. In this paper I argue that there are at least two reasons for disputing the use of risk aversion as a justification for discounting (...) when dealing with longterm decisions, one technical and one ethical. Firstly, I argue that technically, it implies an inconsistency between theory and practice. And secondly, I argue that discounting for uncertainty relies on a form of individualism which, while reasonable in standard microeconomic theory where an agent chooses how to spread her own consumption over her own lifetime, is inappropriate in the context of intergenerational social decisions.

Representation theorems are often taken to provide the foundations for decision theory. First, they are taken to characterize degrees of belief and utilities. Second, they are taken to justify two fundamental rules of rationality: that we should have probabilistic degrees of belief and that we should act as expected utility maximizers. We argue that representation theorems cannot serve either of these foundational purposes, and that recent attempts to defend the foundational importance of representation theorems are unsuccessful. As a result, we (...) should reject these claims, and lay the foundations of decision theory on firmer ground. (shrink)
