Sometimes we make decisions which affect our lives at times when we will hold values that are different from our values at the time the decision is made. What is the reasonable way to make such a choice? Some think we should accept a requirement of temporal neutrality and take both sets of values into account, others think we should decide on the strength of our present values, yet others think that in evaluating what will happen at that (...) other time we should use the values that we will endorse at that time instead of our present values. These views see the problem as one about finding some attitude towards time itself that is distinctively rational. This article argues that these views are subject to serious objections. It suggests that instead we should think in terms of well-being. If a person approves of, or positively responds to, the way their life is going they will experience more well-being than if there is no positive response. The article explores the implications of a positive response condition on well-being for deciding what it is rational to do in cases involving changing goals. (shrink)

The family of theories dubbed ‘luck egalitarianism’ represent an attempt to infuse egalitarian thinking with a concern for personal responsibility, arguing that inequalities are just when they result from, or the extent to which they result from, choice, but are unjust when they result from, or the extent to which they result from, luck. In this essay I argue that luck egalitarians should sometimes seek to limit inequalities, even when they have a fully choice-based pedigree (i.e., result only (...) from the choices of agents). I grant that the broad approach is correct but argue that the temporal standpoint from which we judge whether the person can be held responsible, or the extent to which they can be held responsible, should be radically altered. Instead of asking, as Standard (or Static) Luck Egalitarianism seems to, whether or not, or to what extent, a person was responsible for the choice at the time of choosing, and asking the question of responsibility only once, we should ask whether, or to what extent, they are responsible for the choice at the point at which we are seeking to discover whether, or to what extent, the inequality is just, and so the question of responsibility is not settled but constantly under review. Such an approach will differ from Standard Luck Egalitarianism only if responsibility for a choice is not set in stone—if responsibility can weaken then we should not see the boundary between luck and responsibility within a particular action as static. Drawing on Derek Parfit’s illuminating discussions of personal identity, and contemporary literature on moral responsibility, I suggest there are good reasons to think that responsibility can weaken—that we are not necessarily fully responsible for a choice for ever, even if we were fully responsible at the time of choosing. I call the variant of luck egalitarianism that recognises this shift in temporal standpoint and that responsibility can weaken Dynamic Luck Egalitarianism (DLE). In conclusion I offer a preliminary discussion of what kind of policies DLE would support. (shrink)

The goal of this article is to show that instrumental rationality and utility that have been used in economics for many years does not work well. What is presented in the article is how significant the influence of utilitarianism has been on economics and why the economists get rid of humans’ goals and motivations. It is shown in the article that the human who decides in present is absolutely different from the human who decides over time. Many economists (...) neglected this problem because they wanted to have an effective and simple model. Becker’s economic method is presented as a dead end to which economics has been brought to. It is impossible to connect different selves of one human being by using the utility measure. The works of Schelling and J.S. Mill are used to explain this impossibility. The conclusion of this article is that instrumental rationality and utility have affected economics significantly. But, this simplified view on human nature is no longer valid. Hence, economics needs to think not only about the means but also about the human goals. Economics needs to rebuff relativism and show people how to achieve well-being. If we want to help people with their self-governance, we will have to choose reason over emotions. (shrink)

Automatic preferences can influence a decision maker’s choice before any relevant or meaningful information is available. We account for this element of human cognition in a computational model of problem solving that involves active trial and error and show that automatic biases are not just a beneficial or detrimental property: they are a tool that, if properly managed over time, can give rise to superior performance. In particular, automatic preferences are beneficial early on and detrimental at later (...) stages. What is more, additional value can be generated by a timely rebiasing, i.e., a calculated reversal of the initial automatic preference. Remarkably, rebiasing can dominate not only debiasing but also continuously unbiased decision making. This research contributes to the debate on the adaptiveness of automatic and intuitive biases, which has centered primarily on one-shot controlled laboratory experiments, by simulating outcomes across extended time spans. We also illustrate the value of the novel intervention of adopting the opposite automatic preference—something organizations can readily achieve by changing key decision makers—as opposed to attempting to correct for or simply accepting the ubiquity of such biases.

This paper compares the ethical decisions and attitudes of business students and practitioners. Recent unpublished data from a national study of over 1600 students are contrasted with information reported previously. Students are found consistently to make less ethical choices than practitioners, and there is some indication that students are making less ethical choices in the 1980s than in the 1960s. In addition, both students and practitioners agree that buyers should beware, view the role of business more narrowly, and find (...) fewer incentives to behave ethically over time. Codes of ethics appear to be less influential than the individual's strong personal value system and one's superiors behaving ethically; support for codes is declining. The paper concludes with observations about the limitations and possibilities for survey research in this area drawing on other studies that used the same instrument utilized for this paper. Some implications for future research are suggested. (shrink)

The principle of homophily says that people associate with other groups of people who are mostly like themselves. Many online communities are structured around groups of socially similar individuals. On Twitter, however, people are exposed to multiple, diverse points of view through the public timeline. The authors captured 30,000 tweets about the shooting of George Tiller, a late-term abortion doctor, and the subsequent conversations among pro-life and pro-choice advocates. They found that replies between like-minded individuals strengthen group identity, whereas (...) replies between different-minded individuals reinforce in-group and out-group affiliation. Their results show that people are exposed to broader viewpoints than they were before but are limited in their ability to engage in meaningful discussion. They conclude with implications for different kinds of social participation on Twitter more generally. (shrink)

In this paper we present BTC, which is a complete logic for branchingtime whose modal operator quantifies over histories and whose temporal operators involve a restricted quantification over histories in a given possible choice. This is a technical novelty, since the operators of the usual logics for branching-time such as CTL express an unrestricted quantification over histories and moments. The value of the apparatus we introduce is connected to those logics of agency that are interpreted (...) on branching-time, as for instance Stit Logics. (shrink)

Sometimes a series of choices do not serve one's concerns well even though each choice in the series seems perfectly well suited to serving one's concerns. In such cases, one has a dynamic choice problem. Otherwise put, one has a problem related to the fact that one's choices are spread out over time. This survey reviews some of the challenging choice situations and problematic preference structures that can prompt dynamic choice problems. It also reviews (...) some proposed solutions, and explains how some familiar but potentially puzzling phenomena — including, for example, self-destructive addictive behavior and dangerous environmental destruction — have been illuminated by dynamic choice theory.

This paper examines the importance of aspirations as reference points in a multi-period decision-making context. After stating their personal aspiration level, 172 individuals made six sequential decisions among risky prospects as part of a choice experiment. The results show that individuals make different risky-choices in a multi-period compared to a single-period setting. In particular, individuals’ aspiration level is their main reference point during the early stages of decision-making, while their starting status (wealth level at the start of the experiment) (...) becomes the central reference point during the later stages of their multi-period decision-making.

Even though the Islamic legal tradition advanced its own set of conceptions of time, modern scholarship on Islamic law has not paid much attention to these conceptions. This paper argues that Islamic jurisprudents understood time in moral terms, not as a neutral container or mere background for action, but as a series of opportunities in which the authority of divine revelation and human moral reasoning are articulated. I suggest that the debates over the manners of compliance with (...) divine commands in time were attempts at reaching some form of balance between the considerations of faithfulness to the demands of divine revelation and the practical imperatives of human temporal lives. This argument is advanced through a study of classical debates among jurists within the two major Sunnī schools of jurisprudence on the specific question of whether divine commands that are devoid of time indications should result in immediate or delayed performance.

Models of intertemporal choice draw on three evaluation rules, which we compare in the restricted domain of choices between smaller sooner and larger later monetary outcomes. The hyperbolic discounting model proposes an alternative-based rule, in which options are evaluated separately. The interval discounting model proposes a hybrid rule, in which the outcomes are evaluated separately, but the delays to those outcomes are evaluated in comparison with one another. The tradeoff model proposes an attribute-based rule, in which both outcomes and (...) delays are evaluated in comparison with one another: People consider both the intervals between the outcomes and the compensations received or paid over those intervals. We compare highly general parametric functional forms of these models by means of a Bayesian analysis, a method of analysis not previously used in intertemporal choice. We find that the hyperbolic discounting model is outperformed by the interval discounting model, which, in turn, is outperformed by the tradeoff model. Our cognitive modeling is among the first to offer quantitative evidence against the conventional view that people make intertemporal choices by discounting the value of future outcomes, and in favor of the view that they directly compare options along the time and outcome attributes.

Over time, research programs focusing on the processes that underlie dissonance and regret diverged to the point that the present literature only occasionally draws explicit connections between regret and consistency seeking processes. One of our aims in this chapter is to reestablish the connection between regret and consistency within the context of a theory that examines two independent factors that critically interact to enhance or diminish regret. The first of these is opportunity, which includes both perceptions of past (...) opportunities to make alternative choices and future opportunities to take corrective actions, and the second is mitigation, which is the ability to justify one's actions or otherwise engage regulatory processes that allow for the diminishment of regret. We examine both opportunity and mitigation separately before describing how the two may interact to elicit differential experiences of regret. (shrink)

Two experiments using a realistic version of the selection task examined the relationship between participants' probability estimates of finding a counter example and their selections. Experiment 1 used everyday categories in the context of a scenario to determine whether or not the number of instances in a category affected the estimated probability of a counter-example. Experiment 2 modified the scenario in order to alter participants' estimates of finding a specific counter-example. Unlike Kirby 1994a, but consistent with his proposals, both studies (...) showed that probability estimates significantly predicted selection. Overall results point to the value of understanding selections in terms of their subjective expected utility. (shrink)

This paper reports the results of an experiment designed to uncover the stochastic structure of individual preferences over lotteries. Unlike previous experiments, which have presented subjects with pair-wise choices between lotteries, our design allowed subjects to choose between two lotteries or (virtually) any convex combination of the two lotteries. We interpret the mixtures of lotteries chosen by subjects as a measure of the stochastic structure of choice. We test between two alternative interpretations of stochastic choice: the random (...) utility interpretation and the deterministic preferences interpretation. The main findings of the experiment are that the typical subject prefers mixtures of lotteries rather than the extremes of a linear lottery choice set. The distribution of choices does not change between a first and second asking of the same question. We argue that this provides support for the deterministic preferences interpretation over the random utility interpretation of stochastic choice. As a subsidiary result, we find a small proportion of subjects make choices that violate transitivity, but the level of intransitive choice falls significantly over time. (shrink)

This study will explore the Enlightenment conception of the individual of reason, its attempted formulations in actor biographies, and its ultimate denial by the reality of human identity as multiple, fluid, and dialogical. Such fluidity sought to overcome the marginal status of the stage player through the embodiment of rational models of personality. Some stage celebrities, most notably David Garrick, were offering themselves as public models of identity for the new age of reasoned discourse. This involved the presentation before the (...) public of stage performers as fully realized individuals. However, the unavoidable problem was that presenting an individual, even a renowned stage star, as a living paradigm of the enlightened person of reason would prove elusive. Aside from the inherent contradiction of locating any perfected stereotype in an actual person, the qualities making an individual in full conformity to his or her “reason” did not match the particular cultural qualities demanded for a successful eighteenth-century middle-class Englishman or Englishwoman. Nonetheless, by the last quarter of the eighteenth century, significant advances were made both within the particular profession of acting and before the onstage and offstage public. The acting profession was moving quickly and for the first time in England away from its marginalized status to offer respected agents for cultural change. The new genre of actor biographies as well contributed to this more fully realized formulation of the modern individual. (shrink)

We investigate how the perceived uncertainty of a conditional affects a person's choice of conclusion. We use a novel procedure to introduce uncertainty by manipulating the conditional probability of the consequent given the antecedent. In Experiment 1, we show first that subjects reduce their choice of valid conclusions when a conditional is followed by an additional premise that makes the major premise uncertain. In this we replicate Byrne. These subjects choose, instead, a qualified conclusion expressing uncertainty. If subjects (...) are given a third statement that qualifies the likelihood of the additional premise, then the uncertainty of the conclusions they choose is systematically related to the suggested uncertainty. Experiment 2 confirms these observations in problems that omit the additional premise and qualify the first premise directly. Experiment 3 shows that the qualifying statement also affects the perceived probability of the consequent given the antecedent of the conditional. Experiment 4 investigates the effect of suggested uncertainty on the fallacies and shows that increases in uncertainty reduce the number of certain conclusions that are chosen while affirming the consequent but have no effect on denying the antecedent. We discuss our results in terms of rule theories and mental models and conclude that the latter give the most natural account of our results. (shrink)

In recent years, the psychology of reasoning has been undergoing a paradigm shift, with general Bayesian, probabilistic approaches replacing the older, much more restricted binary logic paradigm. At the same time, dual processing theories have been gaining influence. We argue that these developments should be integrated and moreover that such integration is already underway. The new reasoning paradigm should be grounded in dual processing for its algorithmic level of analysis just as it uses Bayesian theory for its computational level (...) of analysis. Moreover, we propose that, within the new paradigm, these levels of analysis reflect on each other. Bayesianism suggests a specific theoretical understanding of dual processing. Just as importantly, the duality in processing carries over to duality in function; although both types of processes compute degrees of belief, they generate different functions. (shrink)

Parents, after learning of a life-limiting fetal condition (LLFC), experience emotional distress and must consider options that impact the remainder of the pregnancy, their future lives, and family members. For those who continue, little is known about their longterm presence or absence of regret about their choice, the reasons for this feeling, or its impact on their life. The aim of this research was to examine the concept of decision regret in parents who opted to continue a pregnancy affected (...) by an LLFC. The contextual factors, conditions, and consequences surrounding the presence or absence of regret were analyzed.Data were retrieved from a cross-sectional study using the Quality of Perinatal Palliative Care and Parental Satisfaction Instrument. Participants were parents (N = 405) who experienced a life-limiting prenatal diagnosis and opted to continue their pregnancy. Secondary data analysis examined qualitative responses (121/402) to an item addressing regret. Dimensional analysis was “I Would Do It All Over Again”: Cherishing Time and the Absence of Regret in Continuing a Pregnancy after a Life-Limiting Diagnosis Charlotte Wool, Rana Limbo, and Erin M. Denney-Koelsch used to examine data, identifying context, conditions, and consequences associated with the presence or absence of regret.Absence of regret was articulated in 97.5 percent of participants. Parents valued the baby as a part of their family and had opportunities to love, hold, meet, and cherish their child. Participants treasured the time together before and after the birth. Although emotionally difficult, parents articulated an empowering, transformative experience that lingers over time. (shrink)

Next SectionThe principle of respect for autonomy has shaped much of the bioethics' discourse over the last 50 years, and is now most commonly used in the meaning of respecting autonomous choice. This is probably related to the influential concept of informed consent, which originated in research ethics and was soon also applied to the field of clinical medicine. But while available choices in medical research are well defined, this is rarely the case in healthcare. Consideration of ordinary (...) medical practice reveals that the focus on patient choice does not properly grasp the moral aspects involved in healthcare. Medical decisions are often portrayed as if doctors and patients in confidence confront specific decisions about examinations or treatment, yet the reality often involves many different participants, with decisions being made over time and space. Indeed, most of the decisions are never even presented to patients, as it would be unethical to suggest something that is not medically justifiable. The options patients do confront are somewhat arbitrarily constructed within the narrow framework of both what is deemed to be medically appropriate and how the healthcare system is organised practically. While the autonomy discourse has proven valuable, a failure to distinguish between the fields of medical research and clinical medicine has generated a focus on patient choice that does not reflect what is really at stake in healthcare settings. This is alarming, because the current discourse misrepresents medical practice in a way that actually contributes to bioethical self-delusion. (shrink)

British marriage statistics suggest that women of breeding age choose young men. Women past breeding age who could still be raising children extend choices to include older men. After this, women do not marry. The choices of men over 50 are restricted to women between 40 and 55: past breeding but young enough to be raising children; the few men over 50 that marry choose women in this age range.

Background A significant number of women experience childbirth as traumatic. These experiences are often characterised by a loss of control coupled with a perceived lack of support and inadequate communication with health care professionals. Little is known about the choices women make in subsequent pregnancy(s) and birth(s), or why they make these choices. This study aimed to understand these choices and explore the reasons behind them. Methods A longitudinal Grounded Theory Methods (GTM) study involving 9 women was conducted. Over (...) half of the participants had a formal diagnosis of PTSD and/or PND related to the previous birth. Interviews were carried out at 3 timepoints perinatally. These findings are from the first interviews at 12-20 weeks. Results From the first days of pregnancy, this cohort of women were focused on concerns that this birth would be a repeated traumatic experience. The women were deliberately searching out and analysing information about their choices in this pregnancy and birth, and making plans which had two aims; firstly to avoid a repeat of their previous birth experience, and secondly to avoid a loss of control to other people during the birth. The women considered a range of birth choices, from elective caesareans to freebirth. Some women felt well supported by those around them, including health care professionals, partners, friends and family. Others did not, and were anticipating conflict in trying to assert their birth choices. Many early relationships with health care professionals were characterised by fear and mistrust. Discussion Women who have previously experienced a traumatic birth become pregnant again, have a strong desire to avoid a repeat experience and to feel in control of their birth choices. Access to robust information appears to help reduce uncertainty and arm women in their discussions with professionals. Similarly making plans and seeking to have them agreed with health care professionals at an early stage is used a way to reduce the risk of having a further traumatic experience. Implications for practice include supporting women in formulating and confirming pregnancy and birth plans at an early stage to reduce uncertainty and foster a sense of control. (shrink)

In this paper, we analyze an intra-personal game where a decision-maker is summarized by a succession of selves. Selves may (or may not) have conflicting interests, and earlier selves may have imperfect knowledge of the preferences of future selves. At date 1, self-1 chooses a menu, at date 2, the preferences of self-2 realize and self-2 chooses an item from the menu. We show that equilibrium choice is consistent with either a preference for flexibility, a preference for betweenness or (...) a preference for systematic restriction. Overall, the analysis reconciles the decision–theoretic approach of choice over time with the game–theoretic multiple-selves approach. (shrink)

According to libertarianism about free will, at least some of the choices we make are free and undetermined. Many libertarians also accept the thesis that, before we make an undetermined choice, there is a nontrivial objective probability that we will make that choice. In the literature on free will, the ascription of objective probabilities is sometimes justified via an “Argument from Motivation,” which adverts to the fact that typically, in situations of choice, we are more motivated to (...) choose some options over others. In this paper, I will examine this argument and I will argue that it is unsound, as one of its premises is at odds with a widely accepted principle governing the evolution of objective probabilities over time.

The problem of intertemporal choice arises when outcomes are received in different moments of time. This paper presents an axiomatic model of intertemporal choice when consumption in the previous moment of time contributes to utility evaluation of consumption in the current moment. This model generalizes classic discounted utility theory (also known as constant or exponential discounting) in two ways. First, in every moment of time, a decision maker derives utility not only from current consumption but (...) also from “residual” consumption in the previous moment of time. Second, these utilities are discounted with weights that are essentially a quasi-hyperbolic discounting function. The paper presents an application of the proposed model to the problem of optimal consumption and savings given a fixed income (wealth). When a decision maker derives satisfaction from both instantaneous consumption as well as a share of consumption in the previous moment of time, optimal consumption path is cyclic—periods of relatively high consumption are interchanged with periods of relatively low consumption. These cycles decay over time. Asymptotically, the consumption path exhibits conventional properties (constant, increasing or decreasing over time when a gross interest rate multiplied by discount factor is correspondingly equal to, greater than, or less than one).

Is it rational to be moral? How do rationality and morality fit together with being human? These questions are at the heart of David Schmidtz's exploration of the connections between rationality and morality. This inquiry leads into both metaethics and rational choice theory, as Schmidtz develops conceptions of what it is to be moral and what it is to be rational. He defends a fairly expansive conception of rational choice, considering how ends as well as means can be (...) rationally chosen and explaining the role of self-imposed constraints in a rational life plan. His moral theory is dualistic, ranging over social structure as well as personal conduct and building both individual and collective rationality into its rules of recognition for morals. To the "why be moral" question, Schmidtz responds that being moral is rational, but he does not assume we have reasons to be rational. Instead, Schmidtz argues that being moral is rational in a particular way and that beings like us in situations like ours have reasons to be rational in just that way. This approach allows him to identify decisive reasons to be moral; at the same time, it explains why immorality is as prevalent as it is. This book thus offers a set of interesting and realistic conclusions about how morality fits into the lives of humanly rational agents operating in an institutional context like our own. (shrink)

This article argues that existing approaches to programming ethical AI fail to resolve a serious moral-semantic trilemma, generating interpretations of ethical requirements that are either too semantically strict, too semantically flexible, or overly unpredictable. This paper then illustrates the trilemma utilizing a recently proposed ‘general ethical dilemma analyzer,’ GenEth. Finally, it uses empirical evidence to argue that human beings resolve the semantic trilemma using general cognitive and motivational processes involving ‘mental time-travel,’ whereby we simulate different possible pasts and futures. (...) I demonstrate how mental time-travel psychology leads us to resolve the semantic trilemma through a six-step process of interpersonal negotiation and renegotiation, and then conclude by showing how comparative advantages in processing power would plausibly cause AI to use similar processes to solve the semantic trilemma more reliably than we do, leading AI to make better moral-semantic choices than humans do by our very own lights.

People often face preferential decisions under risk. To further our understanding of the cognitive processes underlying these preferential choices, two prominent cognitive models, decision field theory (DFT; Busemeyer & Townsend, 1993) and the proportional difference model (PD; González‐Vallejo, 2002), were rigorously tested against each other. In two consecutive experiments, the participants repeatedly had to choose between monetary gambles. The first experiment provided the reference to estimate the models’ free parameters. From these estimations, new gamble pairs were generated for the second (...) experiment such that the two models made maximally divergent predictions. In the first experiment, both models explained the data equally well. However, in the second generalization experiment, the participants’ choices were much closer to the predictions of DFT. The results indicate that the stochastic process assumed by DFT, in which evidence in favor of or against each option accumulates over time, described people’s choice behavior better than the trade‐offs between proportional differences assumed by PD.

We outline a dual systems approach to temporal cognition, which distinguishes between two cognitive systems for dealing with how things unfold over time – a temporal updating system and a temporal reasoning system – of which the former is both phylogenetically and ontogenetically more primitive than the latter, and which are at work alongside each other in adult human cognition. We describe the main features of each of the two systems, the types of behavior the more primitive temporal (...) updating system can support, and the respects in which it is more limited than the temporal reasoning system. We then use the distinction between the two systems to interpret findings in comparative and developmental psychology, arguing that animals operate only with a temporal updating system and that children start out doing so too, before gradually becoming capable of thinking and reasoning about time. After this, we turn to adult human cognition and suggest that our account can also shed light on a specific feature of our everyday thinking about time that has been the subject of debate in the philosophy of time, which consists in a tendency to think about the nature of time itself in a way that appears ultimately self-contradictory. We conclude by considering the topic of intertemporal choice, and argue that drawing the distinction between temporal updating and temporal reasoning is also useful in the context of characterising two distinct mechanisms for delaying gratification.

Researchers are working to derive sperm from banked testicular tissue taken from pre-pubertal boys who face therapies or injuries that destroy sperm production. Success in deriving sperm from this tissue will help to preserve the option for these boys to have genetically related children later in life. For the twin moral reasons of preserving access and equity in regard to having such children, clinicians and researchers are justified in offering the option to the parents of all affected boys. However, some (...) parents may wish to decline the option to bank tissue from their boys because the technique may seem too unfamiliar or unusual, but over time people may become more comfortable with the technique as they have done with other novel assisted reproductive treatments. Other parents may wish to decline the option because of moral or religious reasons. A prominent natural law theory holds, for example, that the ARTs that would be involved in using sperm derived from banked tissue to produce a child are morally objectionable. Some parents might not want to bank tissue in order to shield their son from using ARTs they see as objectionable. Clinicians and researchers should respect parents who wish to decline banking tissue, but parents should ordinarily embrace choices that protect the possible interests their sons may have as adult men, including the wish to have genetically related children.

Although autonomy is clearly still the paradigm in bioethics, there is increasing concern over its value and feasibility. In agreeing with those concerns, I argue that autonomy is not just a status, but a skill, one that must be developed and maintained. I also argue that nearly all healthcare interactions do anything but promote such decisional skills, since they rely upon assent, rather than upon genuinely autonomous consent. Thus, throughout most of their medical lives, patients are socialised to be (...) heteronomous, rather than autonomous. Yet, at the worst possible time – critical care decision-making – when life and death consequences are attached to the choices, the paradigm shifts and real consent is sought, even demanded, thereby making an often traumatic situation even harder.I go on, though, to also reject paternalistic models of beneficence as an alternative. Rather, I conclude that the problem is so fundamental in healthcare that a genuine solution would require a radical restructuring. I recommend steps that can be taken in the interim to improve the situation and to move toward such a restructuring. (shrink)

Time discounting is the phenomenon that a desired result in the future is perceived as less valuable than the same result now. Economic theories can take this psychological fact into account in several ways. In the economic literature the most widely used type of additive time discounting is exponential discounting. In exponential discounting, the fall of valuation depends by a constant factor on the length of the delay period. It is well known, however, that exponential time discounting (...) often does not describe well how people actually behave. Most people are averse to short delays in gratification now, while their future selves may not mind a bit of extra waiting. This behaviour can be described well by non-exponential discounting functions such as hyperbolic discounting. In hyperbolic discounting, valuations fall rapidly for small delay periods, but the fall gets slower for longer delay periods. Hyperbolic discounting captures phenomena such as procrastination, addiction and in general inconsistency over time. This chapter investigates whether forms of non-exponential discounting, in particular close to the so called Quasi-Hyperbolic model, could also be characterized in terms of dynamically consistent choices when individuals discount the welfare of future selves as well as their payoffs.

Precautionary principles are frequently appealed to both in public policy and in discussions of individual decision-making. They prescribe omission or reduction of an activity, or taking precautionary measures whenever potential harmful effects of the activity surpass some threshold of likelihood and severity. One crucial appeal of precautionary principles has been that they seem to help guard against procrastinating on confronting certain kinds of risk. I raise a challenge for precautionary principles serving as effective action-guiding tools to guard against (policy) inaction, (...) procrastination, or recklessness. Since risks that are sufficiently harmful and sufficiently likely to fulfil the antecedent of a precautionary principle typically accumulate over time, precautionary principles are only effective if they constrain an agent’s decision-making over time. On the basis of this observation, I argue for two claims. First, to yield the verdicts proponents of precautionary principles would like to make, precautionary principles must be understood to be diachronic principles, which requires some added structure to how they are commonly formulated. Second, such diachronic precautionary principles invite policy procrastination and inaction in their own right, due to both the vagueness of thresholds, and because agents will often fail to abide by the principles if they ignore bygone risks.

An objective and relational theory of local time is expounded and its philosophical implications are discussed in Sect. 2. In Sect. 3 certain physical and metaphysical questions concerning time are taken up in the light of that theory. The basic concepts of the theory are those of event, reference frame, chronometric scale, and time function. These are subject to four axioms: existence of events, frames and scales; time is a real valued function; the set of events (...) is compact; and any duration can be subdivided into two contiguous durations. Several theorems are derived, among them the one of the asymmetry of time. And a number of concepts are defined, such as those of time order, instant, and time coordinate. It is argued that the theory, though untestable, belongs to the background of a number of scientific theories. It is also shown that it includes all relational theories of time. The usual confusion between the asymmetry of time and the direction of irreversible processes is clarified. Time reversal is interpreted either as a purely formal operation or as a convenient way of describing motion reversed processes. Time orders are shown to be both relative and objective, apart from the choice of the positive direction, which is conventional. The various attempts to define the direction of time in terms of irreversible processes are shown to be logically untenable and methodologically undesirable. A number of metaphysical questions, such as the one of the reality and the fundamental character of time, are tackled. Finally the occasion is seized to extoll the advantages of systematization over both ordinary language discussions and open context analyses. (shrink)

Because emotion regulation processes operate over time, they potentially change the context in which subsequent ER processes occur. To test this proposal, fifty-two healthy participants completed the ER choice task. Thirty standardized low- and high-intensity negative images were used to generate different emotional contexts in which participants selected between distraction or reappraisal strategies to decrease the intensity of their negative emotion. Participants then implemented their selected strategy and rated their negative emotion. Using a dynamic perspective, we examined (...) as predictors of ER strategy choice, in addition to current stimulus intensity, several contextual factors from the immediately preceding trial: preceding stimulus intensity and strategy choice, and the intensity of negative affect following the previous strategy implementation and thus preceding the current trial. Results replicated earlier findings that participants are more likely to choose distraction for high-intensity images. Extending earlier findings, selecting reappraisal in the preceding trial and greater negative affect preceding the current trial were associated with lower odds of choosing distraction. The lack of significant interactions among the current and preceding trial factors suggests that these effects on ER choice were direct and not through moderating the effect of current stimulus intensity. These findings support dynamic theories of ER. (shrink)

Food-specific inhibition training (FSIT) is a computerised task requiring response inhibition to energy-dense foods within a reaction-time game. Previous work indicates that FSIT can increase the number of healthy foods (relative to energy-dense foods) children choose, and decrease calories consumed from sweets and chocolate. Across two studies, we explored the impact of FSIT variations (e.g., different response signals, different delivery modes) on children’s food choices within a time-limited hypothetical food-choice task. In Study 1, we varied the FSIT (...) Go/No-Go signals to be emotive (happy vs. sad faces) or neutral (green vs. red signs). One-hundred-and-fifty-seven children were randomly allocated to emotive-FSIT, neutral-FSIT, or a non-food control task. Children participated in groups of 4–15. No significant FSIT effects were observed on food choices (all values ofp> 0.160). Healthy-food choices decreased over time regardless of condition (p 0.050). Healthy choices decreased over time in the control group (p= 0.001) but did not change in the two FSIT groups (bothp> 0.300) supporting previous evidence that FSIT may have a beneficial effect on children’s food choices. Ensuring that children perform FSIT with high accuracy (e.g., by using FSIT in quiet environments and avoiding group-testing) may be important for impacts on food choices though. Future research should continue to explore methods of optimising FSIT as a healthy-eating intervention for children. (shrink)

Book description:* Contributions from leading scholars in the field * Timely and important contribution to the moral and political debate about the status of children * Hot Topic The book contains contributions from thirteen distinguished moral and political philosophers on the subject of children. These are new essays and are devoted to a subject that until recently has not been extensively discussed by philosophers. Too often philosophers restrict themselves to the consideration only of the relations between adults. Yet the topic (...) of children is an important one for moral and political philosophy. Recent years have seen an increased concern with the needs and interests of young people. The United Nations Convention on the Rights of the Child which accords a wide range of fundamental rights to children was adopted in 1989 and many states have subsequently ratified the Convention. In this context it is timely and appropriate to ask various questions. If children do not have rights what exactly is their moral status? If they do have rights do they have all the rights that adults have? What rights if any do parents have over children and what is their justification? What duties do parents have towards their own children and towards others in society? How should we educate those who will be the future citizens and workers of our society? What values and what dispositions of character is it appropriate to instil in children? Is the family an obstacle to the realisation of full social justice? Can we in pursuit of justice contemplate the abolition of the family? The book covers the themes of children's rights, parental rights and duties, the family and justice, and civic education.

This paper explains the delayed choice quantum eraser of Kim et al. in terms of the transactional interpretation of quantum mechanics by Cramer. It is kept deliberately mathematically simple to help explain the transactional technique. The emphasis is on a clear understanding of how the instantaneous “collapse” of the wave function due to a measurement at a specific time and place may be reinterpreted as a relativistically well-defined collapse over the entire path of the photon and (...) class='Hi'>over the entire transit time from slit to detector. This is made possible by the use of a retarded offer wave, which is thought to travel from the slits to the detector and an advanced counter wave traveling backward in time from the detector to the slits. The point here is to make clear how simple the transactional picture is and how much more intuitive the collapse of the wave function becomes if viewed in this way. Also, any confusion about possible retro-causal signaling is put to rest. A delayed choice quantum eraser does not require any sort of backward in time communication. This paper makes the point that it is preferable to use the TI over the usual Copenhagen interpretation for a more intuitive understanding of the quantum eraser delayed choice experiment. Both methods give exactly the same end results and can be used interchangeably. (shrink)

For decisions whose consequences accrue over time, there are several possible techniques to compute total utility. One is to discount utilities of future consequences at some appropriate rate. The second is to discount per-period certainty equivalents. And the third is to compute net present values (NPVs) of various possible streams and to then apply the utility function to these net present values. We find that the best approach is to first compute NPVs of various possible income streams and (...) then take the utility of such NPVs. We show the drawbacks of other alternative models of evaluating income streams. The article discusses the advantages of the power and logarithmic forms in the modeling of time preference. These are the only forms for which utility of income and utility of consumption are strategically equivalent. Further, these forms permit the flexibility in the choice of a time period (e.g., monthly or quarterly) without modifying the utility function, thus simplifying analysis. (shrink)

In the early decades of the 20th century, women's access to the historical discipline followed fundamentally two paths. For the first time, some (a small minority) entered the profession as academic historians; others worked outside or on the margins of academia, pursuing their research interests as independent scholars. What did being an independent scholar mean for these women? Was it always a form of externally imposed marginalization? My paper argues that this is not the case. First of all, being (...) an independent scholar did not necessarily mean marginality. Some of these women scholars exerted a deep influence on 20th century historiography, and their work is still influential today. Quite apart from posthumous fame, moreover, it should be noted that the lack of academic affiliation did not necessarily preclude for some of these women the possibility of recognition and influence during their lives. Secondly, we should be careful not to assume that being an independent scholar was invariably an externally imposed marginalization. Some of these women scholars can be defined as ‘obligatory amateurs,’ because they were frustrated in their attempt to pursue an academic career. But others, in contrast, deliberately chose independent scholarship over an academic job, and can thus be defined ‘amateurs by choice.’ What was the motivation behind this choice? I argue that an important factor was the resilience of the amateur tradition in historical writing. The amateur tradition offered a strong counterbalance to women's marginality in academia and a source of positive values and models for their participation in the intellectual life. (shrink)

After the US Supreme Court’s reversal of Roe v. Wade, a number of states have immediately banned abortion. Pro-choice activists are responding by promoting medication abortions – a do-it-yourself form of abortion. Women can take pills at home to induce an abortion in the first few weeks of pregnancy. -/- The Biden Administration [1] has backed the abortion pill, too. Attorney-General Merrick B. Garland and Health and Human Services Secretary Xavier Becerra both issued statements endorsing it. -/- “We stand (...) ready to work with other arms of the federal government that seek to use their lawful authorities to protect and preserve access to reproductive care,” said the Attorney-General. “In particular, the F.D.A. has approved the use of the medication mifepristone. States may not ban mifepristone based on disagreement with the F.D.A.’s expert judgment about its safety and efficacy.” -/- As the New York Times [1] has noted, this sets the scene for legal battles. The obvious one is: will anti-abortion states prosecute medication abortions? -/- But – based on experience in the United Kingdom - the use of the abortion pill could give pro-life doctors headaches as well. -/- In the past year, UK has witnessed the saga of two Catholic doctors who have been brought in front of the professional regulator, the General Medical Council, after accusations of professional misconduct. Their crime? They had supplied abortion pill reversal (APR) treatment to women. Accusations of this misconduct have been brought forward by pro-choice organisations [2]. -/- The problem is that some women might panic when they discover that they are pregnant or are pressured to make a rash decision. They obtain abortion pills, often without seeing a doctor faceto- face, and soon after taking the first pill, they regret their decision. -/- Is it too late for them to save their pregnancy? Not necessarily. -/- A treatment developed in the US works about half the time. It involves the woman taking progesterone after the first abortion pill to counteract the abortifacient action of the drug. -/- Seventy-three women in the UK are reported to have taken a full APR course, of whom, 38 – more than half — successfully remained pregnant. Admittedly, the procedure is controversial [3], with pro-choice writers denouncing it as unproven, unscientific, and unethical. This has triggered some healthcare practitioners and scholars to analyse the commitments of the pro-choice movement to APR. In a recently published paper in The New Bioethics [4], two colleagues, Dominic Whitehouse and Steven Bow, and I argue that those espousing a pro-choice worldview should actually support abortion pill reversal and that the current evidence indicates that they should actually be doing it. -/- While some pro-choice activists might be happy simply to expand women’s reproductive choices, some might also want to ensure that these choices are safe and effective at achieving the desired outcome, which in principle includes maintaining a pregnancy. -/- We then review the scientific evidence with respect to the ability of APR to halt an abortion, look at the potential impact of APR on mental health, as well as its procedural safety. While highlighting that gold-standard evidence is lacking, we note that APR is associated with about two times higher rate of embryo survival compared to not completing the full early medical abortion course, that there is large agreement in the literature that women who are ambiguous about abortion are at risk of poorer mental health outcomes after abortion (and argue that women who request APR fall into this category), and highlight that there is no evidence that APR is more dangerous than abandoning an initiated early medical abortion. -/- The latter fact is important, as the results of the only randomised-controlled trial of APR have been at times misrepresented in the media [5.6], creating the impression that APR is not safe while most of the adverse effects occurred in the study group that did not receive APR. As our paper argues, with respect to APR the two UK doctors were “champions of women’s choice and should be congratulated, not condemned, by pro-choice advocates”. -/- While the cases against the two doctors have now been dropped (and there have even been accusations against a member of one of these pro-choice organisations that they pressurised a patient into complaining about one of the doctors and twisted the patient’s experience of the treatment [7]), we argue that it is important to set-up systems to facilitate the future provision of APR to protect both patients and healthcare staff. -/- Our conclusion is that, while being open to any change in evidence, those espousing a pro-choice outlook should “support calls for an APR framework that will protect women and the healthcare professionals caring for them” “and certainly not oppose” APR. -/- The debate over abortion pill reversal will be heading to the United States soon. It is quite possible that it will be denounced as dangerous misinformation. It’s not. But pro-life defenders should be prepared to defend their ground. -/- This article was first published by Mercatornet. (shrink)
