The existing literature on the relationship between organizational commitment and ethical decision making suggests that ethical decision makers with higher organizational commitment are less likely to engage in ethically questionable behaviors. The ethical behaviors previously studied in an organizational commitment context have been organization-harm issues in which the organization was harmed and the individual benefited (e.g., overstating an expense report). There is another class of ethical issues in an organizational context, however. These other issues, termed organization-gain (...) issues, focus on the organization obtaining a benefit while outsiders, such as investors, are harmed (e.g., overstating reported revenue). We explore whether individuals with higher organizational commitment are more or less likely to engage in questionable behaviors that benefit the organization. Results of our study indicate that individuals with higher organizational commitment are less likely to engage in ethically questionable behaviors, regardless of whether the behaviors are organization-harm or organizational-gain issues.

Research on organizational epistemic vice alleges that some organizations are epistemically malevolent, i.e. they habitually harm others by deceiving them. Yet, there is a lack of empirical research on epistemic malevolence. We connect the discussion of epistemic malevolence to the empirical literature on organizational deception. The existing empirical literature does not pay sufficient attention to the impact of an organization’s ability to control compromising information on its deception strategy. We address this gap by studying eighty high-penalty corporate misconduct (...) cases between 2000 and 2020 in the United States. We find that organizations use two different strategies to deceive: Organizations ‘sow doubt’ when they contest information about them or their impacts that others have access to. By contrast, organizations ‘exploit trust’ when they deceive others by obfuscating, concealing, or falsifying information that they themselves control. While previous research has focused on cases of ‘sowing doubt’, we find that organizations ‘exploit trust’ in the majority of cases that we studied. This has important policy implications because the strategy of ‘exploiting trust’ calls for a different response from regulators and organizations than the strategy of ‘sowing doubt’. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Invisible HarmKimberly ZieselmanI’m a 48–year–old intersex woman born with Androgen Insensitivity Syndrome (AIS) writing to share my personal experience as a patient affected by a Difference of Sex Development (DSD). Although I appear to be a DSD patient “success story”, in fact, I have suffered and am unsatisfied with the way I was treated as a young patient in the 1980’s, and the continued lack of appropriate care for (...) intersex people even today.As the Executive Director of the advocacy organization Advocates for Informed Choice and a board member of the AIS–DSD Support Group since 2012, I have heard doctors reference the “silent happy majority” of DSD patients all too often. They speak [End Page 122] of patients who were treated in childhood and went on to live (seemingly) contented lives. It appears however that doctors have drawn this conclusion from the fact that most of their patients have not returned to complain about their treatment. While there is little evidence to support the success doctors claim, there is quite a bit of evidence that suggests my suffering is the norm rather than the exception.Medical professionals would likely include me in that “silent majority,” only seeing a woman who identifies and appears typically female, graduated law school, married for over twenty years, with adopted children and a successful career. And while I have been fortunate in many ways, I no longer want my voice to be presumed buried within that silent majority. Instead, I am speaking out today to tell my story.My StoryAt age 15 I was diagnosed with amenorrhea and referred to a reproductive oncologist who told my parents I had a partially developed uterus and ovaries that would likely soon become cancerous. We were told my vagina was abnormally short and might require surgery in order to have heterosexual intercourse.Neither my parents nor I was ever told I had AIS and XY chromosomes, or that the gonads being removed were testes, not ovaries. I was told I needed a “full hysterectomy” to prevent cancer and hormone replacement therapy. That summer I spent my 16th birthday recuperating from surgery. I spent the next 25 years living a lie.A lie that has had a profound and harmful impact on me.At some level, I knew I was not being told the whole truth. My parents’ and the doctors’ actions signaled to me something more might be going on. But I was afraid to ask questions; my parents were distressed and I didn’t want to cause them any more pain. Over the years I have wondered just how much my parents knew but withheld from me (albeit with good intentions). I sensed something awful was being hidden from me, and I didn’t know whom I could trust.When I asked my doctor if I could meet someone else with my condition, I was told I was different, that there was “nobody” with my medical condition in the world, that my situation was “very rare.” I was told to get on with my life and not talk about my surgery because it wasn’t important; I was healthy and could adopt if I wanted to become a parent. I was told I must take a hormone pill each day for the rest of my life to stay healthy.But what I heard was, “you are not a real woman: you are a damaged freak, so go out and fake the rest of your life and be sure nobody knows your secret.” So that’s what I did. I was a “good girl” and took my pills, didn’t ask questions and did what the men in white coats asked me to do. There was no support provided for either my parents or me. No social workers, no therapists. Perhaps most shockingly, there was no true informed consent.A few years ago I was diagnosed with post-traumatic stress syndrome caused by anxiety I had been harboring for over two decades about my past surgery and fear of getting cancer. I decided to obtain my medical records from the hospital and discover the truth.Covering several pages of... (shrink)

Delusional beliefs are typically pathological. Being pathological is clearly distinguished from being false or being irrational. Anna might falsely believe that his husband is having an affair but it might just be a simple mistake. Again, Sam might irrationally believe, without good evidence, that he is smarter than his colleagues, but it might just be a healthy self-deceptive belief. On the other hand, when a patient with brain damage caused by a car accident believes that his father was replaced by (...) an imposter or another patient with schizophrenia believes that “The Organization” painted the shops on a street in red and green to convey a message, these beliefs are not merely false or irrational. They are pathological. What makes delusions pathological? This paper explores the negative features because of which delusional beliefs are pathological. First, I critically examine the proposals according to which delusional beliefs are pathological because of (1) their strangeness, (2) their extreme irrationality, (3) their resistance to folk psychological explanations or (4) impaired responsibility-grounding capacities of people with them. I present some counterexamples as well as theoretical problems for these proposals. Then, I argue, following Wakefield’s harmful dysfunction analysis of disorder, that delusional beliefs are pathological because they involve some sorts of harmful malfunctions. In other words, they have a significant negative impact on wellbeing (=harmful) and, in addition, some psychological mechanisms, directly or indirectly related to them, fail to perform the jobs for which they were selected in the past (=malfunctioning). An objection to the proposal is that delusional beliefs might not involve any malfunctions. For example, they might be playing psychological defence functions properly. Another objection is that a harmful malfunction is not sufficient for something to be pathological. For example, false beliefs might involve some malfunctions according to teleosemantics, a popular naturalist account of mental content, but harmful false beliefs do not have to be pathological. I examine those objections in detail and show that they should be rejected after all. (shrink)

In March 2020, the World Health Organization declared the disease caused by SARS-CoV-2 coronavirus “pandemic.” To reduce the risk of contamination, many countries have ordered a lockdown characterized by social distancing and restrictive isolation measures. While the lockdown has proven to be quite effective in terms of physical health, little is known about its impact on couple satisfaction in a dyadic perspective. The current research was a 4-waves longitudinal study with the objective to examine the trajectory of couple satisfaction (...) during the lockdown with a dyadic perspective, including the presence of children at home, the number of hours spent together, and the duration of the relationship as time-invariant predictors and the partner’s couple satisfaction trajectory as a time-varying covariate. Results showed positive intraindividual changes in couple satisfaction during the lockdown, especially an increase in partners’ effectiveness for resolving couple conflicts and a decrease in partners’ aggressiveness. Partners had also perceived the influence of the lockdown as more and more positive over time on couple and family functioning. Finally, the couple satisfaction of both partners changed in tandem during the lockdown: The perception of the couple relationship seems to similarly evolve between partners. (shrink)

Product-harm crisis is an important organizational management topic due to the potential detrimental business impact. Organizations are more vulnerable than ever to the possibility of product related incidents disrupting business at any point in the supply chain. To counteract this implicit threat to an organizations reputation and financial wellbeing, if properly deployed, continuity management fosters the ability to run in the face of a crisis event; whereby business continuity management induces the means for appropriate product-harm crisis responses. In (...) this study, the author synthesizes selected published research presenting product-harm crisis management considerations. Based on an assigned literature review; the author summarizes article content, compares and contrasts methods and extrapolates results and conclusions garnered from the selected scholarly research; then provides an actionable recommendation for enabling effective product-harm crisis management.

This work employs Elizabeth Cripps’ collectivist account of responsibility for climate change in order to ground an individual duty to reduce one’s GHG emissions. This is significant not only as a critique of Cripps, but also as an indication that even on some collectivist footings, individuals can be assigned primary duties to reduce their emissions. Following Cripps, this work holds the unstructured group of GHG emitters weakly collectively responsible for climate change harms. However, it argues against Cripps that what follows (...) from this is a corresponding collective duty to act qua group to bring about an end to the harm and a derivative duty for each emitter to promote the required organization of a group capable of this. Instead, this work argues that acts of GHG emission, to the extent that they are avoidable and performed with requisite knowledge, make one into a member of a group that is morally responsible for climate-related harms. Thus, individual emitters who can do otherwise should recognize themselves as members of a group that collectively harms. Subsequently, they should take all possible steps in order to renounce their membership (e.g. by reducing their GHG emissions). (shrink)

The growing literature on gender in armed conflict and the debates over post-conflict reparations for women, focus on the prevalence and harms of sexual violence. While this focus has recently been critiqued, there are few articulations of other types of gendered injuries. This article decentres the emphasis on sexual violence by examining the intersection between forced displacement and political insecurity. Based on extensive field research in Colombia, and using as an example a case study of an internally displaced women’s grassroots (...) organization in Cartagena, Colombia, this article examines political insecurity as a specifically gendered harm. It reflects on the concrete circumstances of insecurity, on the relevance of traditional gender roles in the constitution of insecurity, and on the challenges for court-ordered remedies. This widening of the scope of attention also invites complex reflection on the possibility of transformative reparations in post-conflict situations. (shrink)

Abstract:Organizational justice and injustice are widely noted influences on employees’ ethical behavior. Corporate ethics programs also raise issues of justice; organizations that fail to “follow-through” on their ethics policies may be perceived as violating employees’ expectations of procedural and retributive justice. In this empirical study of four large corporations, we considered employees’ perceptions of general organizational justice, and their perceptions of ethics program follow-through, in relation to unethical behavior that harms the organization, and to employees’ willingness to help the (...) organization by reporting ethical problems and issues to management. Results show that when employees perceive general organizational justice and ethics program follow-through, there is less unethical behavior and greater willingness to report problems. General justice and ethics program follow-through also interact with each other, showing that the impact of ethics initiatives is influenced by the organizational context. (shrink)

This conceptual paper draws on cognitive theory and attribution theory to develop a process model of managerial dissonance and responsibility attribution after harm-doing. Although extant harm-doing literature assumes managerial backing for such decisions, this study suggests that there will, at times, be acts of organizationally mandated harm-doing that managers believe are unnecessary. In these cases, it is proposed that managers will experience dissonance from enacting the harm-doing event, resulting in the externalization of responsibility to either the (...) organization or the harm-doing target. This paper examines the challenges faced by the manager through each phase of the dissonance resolution process and possible outcomes of the process. This study concludes with the model’s implications for moral theorizing. (shrink)

Artificial intelligence (AI) assurance is an umbrella term describing many approaches—such as impact assessment, audit, and certification procedures—used to provide evidence that an AI system is legal, ethical, and technically robust. AI assurance approaches largely focus on two overlapping categories of harms: deployment harms that emerge at, or after, the point of use, and individual harms that directly impact a person as an individual. Current approaches generally overlook upstream collective and societal harms associated with the development of systems, such as (...) resource extraction and processing, exploitative labour practices and energy intensive model training. Thus, the scope of current AI assurance practice is insufficient for ensuring that AI is ethical in a holistic sense, i.e. in ways that are legally permissible, socially acceptable, economically viable and environmentally sustainable. This article addresses this shortcoming by arguing for a broader approach to AI assurance that is sensitive to the full scope of AI development and deployment harms. To do so, the article maps harms related to AI and highlights three examples of harmful practices that occur upstream in the AI supply chain and impact the environment, labour, and data exploitation. It then reviews assurance mechanisms used in adjacent industries to mitigate similar harms, evaluating their strengths, weaknesses, and how effectively they are being applied to AI. Finally, it provides recommendations as to how a broader approach to AI assurance can be implemented to mitigate harms more effectively across the whole AI supply chain. (shrink)

The aim of this study is to investigate the necessity of revising the Ethics Code of the Psychology and Counseling Organization of the Islamic Republic of Iran with respect to people’s rights and dignity and to avoid unfair discriminations toward sexual orientation and gender identity. It is said that confused diagnoses; wrong decision making; unethical practice; and the subsequent harm caused to lesbian, gay, bisexual, and transgender clients result from the lack of a clear code and relevant guidelines. (...) In addition, certain conditions in Iran lead professional psychologists and researchers to avoid researching sexual minorities and gender identity, which negatively impacts the Ethics Code of the PCOIRI. Iranian and Western researchers have identified four primary sources to which psychologists and counselors can refer when faced with ethical dilemmas: developmental psychology, professional ethics codes, philosophy of psychology literature, and available researches and compilations on professional ethics. Finally it is suggested that, when dealing with homosexual clients and the related ethical dilemmas, Iranian psychologists and counselors need clear and specific guidelines and a professional ethics code developed from more appropriate reference points than legal and religious sources.

Contact between culturally distinct human groups in the contemporary ‘glocal’ -global and local- world is much greater than at any point in history. The challenge we face is the identification of the most convenient ways to organise the coexistence of different human language groups in order that we might promote their solidarity as members of the same culturally developed biological species. Processes of economic and political integration currently in motion are seeing increasing numbers of people seeking to become polyglots. Thus, (...) English is establishing itself as the usual world supra-language, although it coexists with other lingua francas that are widely used in certain parts of the globe. All this communicative reorganization of the human species may very well pose new problems and aggravate existing tensions as regards language and identity. It would seem that these processes comprise at least four major conceptual dimensions which must be taken into account above all else, as they are both widespread and, left unaddressed, may lead to significant social instability. These dimensions concern linguistic recognition, communicability, sustainability and integration. While accepting the utility of having an inter-national language, the keystone of the system is clearly that it must ensure the linguistic sustainability of each group. The basic principle is likely to be functional subsidiarity, i.e., whatever can be done by the local language should not be done by another one which is more global. As in the quote from Paracelsus --“the dose alone makes the poison”-- contact between languages is not ‘poisonous’ per se, but when the correct dose is exceeded it can prove harmful to the language whose position is weaker. A multilingual and communicated humanity is possible. (shrink)

Through exploring multiple contemporary conceptions of justice, this article illustrates that justice matters when considering outcomes in nongovernmental organization assistance. In environmental justice scholarship, the term justice has been underproblematized, assuming a tacit understanding of the concept as fairness or equitable distribution of environmental harms. Using the rebuilding of two heavily damaged poor and minority neighborhoods in post–Katrina New Orleans as case studies, this article makes evident the different conceptualizations of justice embedded within the strategies and techniques of NGOs (...) and community organizations. Examining both practices and outcomes, I argue that the definition of justice that NGOs implicitly or explicitly adopt in their strategies and technologies of assistance can lead to very different results in postdisaster neighborhood revitalization. For science and technology studies, conceptions of justice can help articulate a more critical social science that opens up the descriptive/normative divide. This is important in thinking about equitable social change and allied policy—as it applies not only to NGO assistance but also to other science and technology issues that intersect with marginalized communities as well.

This book is intended to help transform epistemology - the traditional study of knowledge - into a rigorous discipline by removing conceptual roadblocks and developing formal tools required for a fully naturalized epistemology. The evolutionary approach which Harms favours begins with the common observation that if our senses and reasoning were not reliable, then natural selection would have eliminated them long ago. The challenge for some time has been how to transform these informal musings about evolutionary epistemology into a rigorous (...) theoretical discipline capable of complementing current scientific studies of the evolution of cognition with a philosophically defensible account of meaning and justification.

ABSTRACTThe Theory of Event Coding predicts that exposure to affective cues can automatically trigger affectively congruent behaviour due to shared representational codes. An intriguing hypothesis from this theory is that exposure to aversive cues can automatically trigger actions that have previously been learned to result in aversive outcomes. Previous work has indeed found such a compatibility effect on reaction times in forced-choice tasks, but not for action selection in free-choice tasks. Failure to observe this compatibility effect for aversive cues in (...) free choice tasks suggests that control processes aimed at directing behaviour toward positive outcomes may overrule the automatic activation of affectively congruent responses in case of aversive cues. The present study tested whether minimising such control could cause selection of actions that have been learned to result in aversive outcomes. Results showed incidental exposure to aversive cues biased selection of behaviours with learned aver... (shrink)

Conventional wisdom has it that evolution makes a sham of morality, even if morality is an adaptation. I disagree. I argue that our best current adaptationist theory of meaning offers objective truth conditionsfor signaling systems of all sorts. The objectivity is, however, relative to species – specifically to the adaptive history of the signaling system in question. While evolution may not provide the kind of species independent objective standards that (e.g.) Kantians desire, this should be enough for the practical work (...) of justifying our confidence in the objectivity of moral standards. If you believe morality is an adaptation, you should be a moral realist. (shrink)

Ten years ago, researchers using event-related brain potentials to study language comprehension were puzzled by what looked like a Semantic Illusion: Semantically anomalous, but structurally well-formed sentences did not affect the N400 component—traditionally taken to reflect semantic integration—but instead produced a P600 effect, which is generally linked to syntactic processing. This finding led to a considerable amount of debate, and a number of complex processing models have been proposed as an explanation. What these models have in common is that they (...) postulate two or more separate processing streams, in order to reconcile the Semantic Illusion and other semantically induced P600 effects with the traditional interpretations of the N400 and the P600. Recently, however, these multi-stream models have been called into question, and a simpler single-stream model has been proposed. According to this alternative model, the N400 component reflects the retrieval of word meaning from semantic memory, and the P600 component indexes the integration of this meaning into the unfolding utterance interpretation. In the present paper, we provide support for this “Retrieval–Integration ” account by instantiating it as a neurocomputational model. This neurocomputational model is the first to successfully simulate the N400 and P600 amplitude in language comprehension, and simulations with this model provide a proof of concept of the single-stream RI account of semantically induced patterns of N400 and P600 modulations.

Moral norms are the rules of morality, those that people actually follow, and those that we feel people ought to follow, even when they don’t. Historically, the social sciences have been primarily concerned with describing the many forms that moral norms take in various cultures, with the emerging implication that moral norms are mere arbitrary products of culture. Philosophers, on the other hand, have been more concerned with trying to understand the nature and source of rules that all cultures ought (...) to follow, with relatively little regard for what people actually do. The tension between the two approaches has to do with whether there are any standards higher than the whims of culture in determining right and wrong. Typically, the social sciences say “no”, pointing at the diversity of moral beliefs. Most philosophers (along with people of moral conviction) feel that there must be some deeper source of morality than the trends and fads of culture. Unfortunately, the nature and source of such standards has remained something of a mystery. Recent work on the evolution of norms has changed this picture dramatically. (shrink)

Expectation-based theories of language comprehension, in particular Surprisal Theory, go a long way in accounting for the behavioral correlates of word-by-word processing difficulty, such as reading times. An open question, however, is in which component of the Event-Related brain Potential signal Surprisal is reflected, and how these electrophysiological correlates relate to behavioral processing indices. Here, we address this question by instantiating an explicit neurocomputational model of incremental, word-by-word language comprehension that produces estimates of the N400 and the P600—the two most (...) salient ERP components for language processing—as well as estimates of “comprehension-centric” Surprisal for each word in a sentence. We derive model predictions for a recent experimental design that directly investigates “world-knowledge”-induced Surprisal. By relating these predictions to both empirical electrophysiological and behavioral results, we establish a close link between Surprisal, as indexed by reading times, and the P600 component of the ERP signal. The resultant model thus offers an integrated neurobehavioral account of processing difficulty in language comprehension. (shrink)

Stories about near-death experiences draw much attention from the general public and are extensively discussed by medical doctors and neuroscientists. However, though eschatology belongs to their core business, only few theologians participate in the debate. This article proposes a theological interpretation of NDEs as ‘private revelations’. I first give a critical analysis of the development of the modern, allegedly ‘scientific’, concept of NDE. This concept changes concrete personal testimonies into statistical data that are used as scientific evidence for the existence (...) of an immortal soul. Next, the main criticisms against this concept from neurosciences, study of mysticism and philosophy of mind are discussed. Finally, I argue that ‘private revelation’ is a useful model for a theological understanding of NDEs and that an analogy from Thomas Aquinas’ view on prophetic dreams can help to account for the specific circumstance of imminent death. The interpretation I propose can do justice to the impression NDEs make on people, but can also accept and meet some of the most important criticisms raised against the modern concept of NDEs.

Information theory offers a measure of "mutual information" which provides an appropriate measure of tracking efficiency for the naturalistic epistemologist. The statistical entropy on which it is based is arguably the best way of characterizing the uncertainty associated with the behavior of a system, and it is ontologically neutral. Though not appropriate for the naturalization of meaning, mutual information can serve as a measure of epistemic success independent of semantic maps and payoff structures. While not containing payoffs as terms, mutual (...) information places both upper and lower bounds on payoffs. This constitutes a non-trivial relationship to utility. (shrink)

Existing research demonstrates a positive connection between psychedelics and increased nature relatedness. Enhanced affective ties toward nature are widely framed as being built into the pharmakon itself, and the relevance of experiences remains little understood. This paper turns to neoshamanic ayahuasca ceremonies in Europe, exploring the way specialists and attendants refer to nature in speech and performance. I argue that ritual framings performed during these ceremonies provide fertile ground for affective ties to emerge through substance‐induced experiences. I trace such framings (...) by exploring how medicine and healers are being coded; how specific materialities are rendered meaningful; and how individual experiences are discussed at such retreats. I argue that even while participants prioritize individual healing, personal development, or the satisfaction of psychonautical curiosity, environmentalism appears to be anchored by the proceedings themselves. Thus, this paper opens up for analysis ceremonial substance use as a contact zone where coherence is produced intersubjectively. (shrink)

Skyrms describes how evolutionary models are helping us understand unselfish or cooperative behaviour in humans and animals. Mechanisms which can stabilize cooperative behaviour are sensitive to population densities, however. This creates the need for agent-based evolutionary models which depict individual interactions, spatial locations, and stochastic effects. One such model suggests that hostile environments may provide conditions conducive to the emergence and stabilization of cooperative behaviour. In particular, simulations show that random extinctions can keep population densities low, provide ongoing colonization opportunities, (...) and insulate cooperative communities from invasion. Agent-based and population models play complementary roles in furthering our understanding evolutionary processes. (shrink)

Empirical research has discovered that experimental subjects in ultimatum bargaining situations generally fail to play the decision-theoretic optimum strategy, and instead play something between that strategy and a fair split. In evolutionary dynamics, fair division and nearly fair division strategies often go to fixation and weakly dominated strategies can do quite well. Computer simulations were done using three different ultimatum bargaining games as determinates of fitness. (1) No tendency toward the elimination of weakly dominated strategies was observed, with or without (...) mutation. (2) Strategies making fair demands had sizable basins of attraction. (3) In a system where five different demands can be made, demands closest to (approximately) 91% had the largest basins of attraction. (4) If the strategies have thresholds for acceptable demands, rather than individuated responses to each demand, the apparent optimum demand may be quite low: 64% for one set of trials. (shrink)

The concept of information tempts us as a theoretical primitive, partly because of the respectability lent to it by highly successful applications of Shannon’s information theory, partly because of its broad range of applicability in various domains, partly because of its neutrality with respect to what basic sorts of things there are. This versatility, however, is the very reason why information cannot be the theoretical primitive we might like it to be. “Information,” as it is variously used, is systematically ambiguous (...) between whether it involves continuous or discrete quantities, causal or noncausal relationships, and intrinsic or relational properties. Many uses can be firmly grounded in existing theory, however. Continuous quantities of information involving probabilities can be related to information theory proper. Information defined relative to systems of rules or conventions can be understood relative to the theory of meaning . A number of causal notions may possibly be located relative to standard notions in physics. Precise specification of these distinct properties involved in the common notion of information can allow us to map the relationships between them. Consequently, while information is not in itself the kind of single thing that can play a significant unifying role, analyzing its ambiguities may facilitate headway toward that goal. (shrink)
