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. This research intends to bridge the gap in the literature by examining whether CEP helps firms to reduce their financial risk. 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.

The winner’s curse in auctions might emerge from asymmetric information and/or from some willingness to pay for winning. This article is based on a sealed-bid common value first price auction, with a net loss for the subject with the second highest bid. The results show the existence of a trade-off between the magnitude of the potential loss and the willingness to pay for the victory. In the context of public procurement these results suggest that companies are willing to overpay small (...) contracts to gain a sort of ‘free advertising’, whereas this is not the case when the contracts are large.

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)

The research theorizes how hubris impacts ethical decision making and develops empirical evidence that earnings manipulation is more likely at firms led by CEOs influenced by hubris. The theory posits that hubris impairs moral awareness by causing decision makers to ignore external factors that otherwise drive such awareness. Additionally, these individuals apply a flawed subjective assessment of the decision they face which further impairs moral awareness. The predicted result is that hubris leads managers to invoke an amoral decision process which (...) causes a higher incidence of unethical behavior among these individuals. An empirical study investigates the relationship between CEO hubris and the unethical practice of earnings manipulation. This study finds a significant correlation between CEO hubris and earnings manipulation at the firms they lead, an outcome broadly consistent with the theory developed. (shrink)

Using the behavioral agency model, we analyze how two compensation design characteristics, pay-performance sensitivity and duration of CEO compensation, affect corporate social performance. We find that the performance sensitivity of CEO pay is negatively associated with poor social performance but also negatively affects strong social performance. These results suggest that pay-performance sensitivity increases the relevance of potential negative consequences of poor social performance. However, the ‘insurance’ benefits of strong social performance may also become less relevant. With respect to the duration (...) of CEO compensation, we find that it reduces poor social performance. This finding confirms arguments that a long-term compensation time horizon increases the perceived threat that the negative effects of poor social performance will become visible. With our findings, we integrate behavioral agency theory with the traditional stakeholder views. (shrink)

This paper extends arguments about the potential for reflexive governance in agri-food sustainability by linking food ethics to the notion of ‘unintended consequences’ and ‘responsibilisation’. Analysis of sustainable consumption governance shows the way authorities and intermediaries use food waste reduction projects to ‘responsibilise’ the consumer, including recent examples of shared responsibility. This paper takes this argument further by developing a ‘strategies of responsibilisation’ framework that connects relations between food system outcomes, problematisation in public discourse and strategies of responsibilisation in agri-food (...) governance. A food and drink waste case study of strategies to introduce reusable coffee cups in UK coffee shops and food retail chains is examined to exemplify relations between problematisation and responsibilisation. We examine problematisation and responsibilisation discourses that have emerged in relation to the issue, particularly in relation to single-use plastics, together with emerging governance arrangements and their underlying rationalities. The case study shows two key things: firstly, how ethical questions about food in public discourses connect to wider environmental planetary concerns ; and secondly, how responsibility has emergent and dynamic properties, which we term ‘cycles of responsibilisation’. The paper concludes by assessing the wider value of applying a responsibility framework to examine governance responses to increasingly complex agri-food system sustainability challenges. (shrink)

Decision framing concerns how individuals build internal representations of problems and how these determine the choices that they make. Research in this area has been dominated by studies of the framing effect, showing reversals in preference associated with the form in which a decision problem is presented. While there are studies that fail to reveal this effect, there is at present no theory that can explain why and when the effect occurs. The purpose of this article is to present a (...) selective review of research and use this to argue for a new framework for considering decision framing, to interpret past studies, and to set an agenda for future research. A simple information-processing model is developed. The model provides the basis for arguing that previous research has taken too narrow a view of how decision problems are internally represented and how these representations are transformed into choice behaviour. In addition, the model is used to highlight the importance of decision content and context. (shrink)

This article develops an axiom system to justify an additive representation for a preference relation ${\succsim}$ on the product ${\prod_{i=1}^{n}A_{i}}$ of extensive structures. The axiom system is basically similar to the n-component (n ≥ 3) additive conjoint structure, but the independence axiom is weakened in the system. That is, the axiom exclusively requires the independence of the order for each of single factors from fixed levels of the other factors. The introduction of a concatenation operation on each factor A i (...) makes it possible to yield a special type of restricted solvability, i.e., additive solvability and the usual cancellation on ${\prod_{i=1}^{n}A_{i}}$ . In addition, the assumption of continuity and completeness for A i implies a stronger type of solvability on A i . The additive solvability, cancellation, and stronger solvability axioms allow the weakened independence to be effective enough in constructing the additive representation. (shrink)

In this work, we present some traits of the socio-political and economic thought of Giuseppe Toniolo, who lived in Italy at the turn of the XIX and XX century, with special reference to the contribution that the Italian economist and sociologist gave to the definition and implementation of the principle of subsidiarity and to the ethical foundation of economic science. After outlining the definition of the subsidiarity principle in the first paragraph, we sketch the historical background in which Toniolo lived (...) and operated. We then focus on the ethical factor and on the concept of subsidiary State emerging from Toniolo’s writings. Finally, we present some of the main elements of Toniolo’s legacy with reference to the current economic and socio-political debate. (shrink)

Ethical leadership is an important construct in the literature on behavioral ethics in organizations, given its link with employee attitudes and behaviors. What remains unclear, however, is what leader characteristics are associated directly with ethical leader perceptions and indirectly with employee unethical behavior. In this paper, we use a socio-cognitive lens to integrate goal orientation theory with the literature on ethical behavior in organizations. Specifically, we propose that certain patterns of managers’ goal-oriented behavior provide signals and cues to employees about (...) their managers’ ethical leadership, which then relates to employee displays of more unethical behavior. Using a sample of 265 manager–employee dyads, our findings largely support our claims. We found that leader performance-avoid goal orientation was negatively related to perceptions of ethical leadership and positively related to employee unethical behavior. Moderated mediation tests indicated that the positive indirect effect of leader performance-avoid goal orientation on employee unethical behavior through perceptions of ethical leadership was attenuated by higher levels of leader learning goal orientation. Taken together, these findings suggest that when leaders emphasize avoiding failure while downplaying the importance of personal learning and development, employees perceive them as less ethical and are more willing to engage in ethical misconduct. We discuss implications of our findings for both theory and practice. (shrink)

John Dewey and Ludwig Wittgenstein offer devastating critiques of the dominant model of human action that each inherited in their own time. Dewey, very early in his philosophical career, ostensibly put the stimulus–response mechanical understanding of action to rest with his “reflex-arc” concept article. Wittgenstein famously redescribed action as moves within language games that interconnect to constitute an interpretively open-ended form of life. In each case, these fundamental insights serve as heuristics, guiding our intellectual activity with regard to understanding our (...) practices, and as reminders in approaching problems. Several scholars have interpreted Dewey and Wittgenstein as allies in a grand project of... (shrink)

The susceptibility of decision-makers’ choices to variations in option framing has been attributed to individual differences in cognitive style. According to this view, individuals who are prone to a more deliberate, or less intuitive, thinking style are less susceptible to framing manipulations. Research findings on the topic, however, have tended to yield small effects, with several studies also being limited in inferential value by methodological drawbacks. We report two experiments that examined the value of several cognitive-style variables, including measures of (...) cognitive reflection, subjective numeracy, actively open-minded thinking, need for cognition, and hemispheric dominance, in predicting participants’ frame-consistent choices. Our experiments used an isomorph of the Asian Disease Problem and we manipulated frames between participants. We controlled for participants’ sex and age, and we manipulated the order in which choice options were presented to participants. In Experiment 1 (N = 190) using an undergraduate sample and in Experiment 2 (N = 316) using a sample of Amazon Mechanical Turk workers, we found no significant effect of any of the cognitive style measures taken on predicting frame-consistent choice, regardless of whether we analyzed participants’ binary choices or their choices weighted by the extent to which participants preferred their chosen option over the non-chosen option. The sole factor that significantly predicted frame consistent choice was framing: in both experiments, participants were more likely to make frame consistent choices when the frame was positive than when it was negative, consistent with the tendency towards risk aversion in the task. The present findings do not support the view that individual differences in people’s susceptibility to framing manipulations can be substantially accounted for by individual differences in cognitive style.

The aim of this article is to question the epistemic presuppositions of applying behavioural science in public policymaking. Philosophers of science who have examined the recent applications of the behavioural sciences to policy have contributed to discussions on causation, evidence, and randomised controlled trials. These have focused on epistemological and methodological questions about the reliability of scientific evidence and the conditions under which we can predict that a policy informed by behavioural research will achieve the policymakers’ goals. This paper argues (...) that the philosophical work of Helen Longino can also help us to have a better and fuller understanding of the knowledge which the behavioural sciences provide. The paper advances an analysis of the knowledge claims that are made in the context of policy applications of behavioural science and compares them with the behavioural research on which they are based. This allows us to show that behavioural policy and the debates accompanying it are based on an oversimplified understanding of what knowledge behavioural science actually provides. Recognising this problem is important as arguments that justify reliance on the behavioural sciences in policy typically presume this simplification. (shrink)
