This paper proposes a novel account of why intertemporal decisions tend to display impatience: People pay more attention to the opportunity costs of choosing larger, later rewards than to the opportunity costs of choosing smaller, sooner ones. Eight studies show that when the opportunity costs of choosing smaller, sooner rewards are subtly highlighted, people become more patient, whereas highlighting the opportunity costs of choosing larger, later rewards has no effect. This pattern is robust to variations in the choice task, to (...) the participant population, and is observed for both incentivized and hypothetical choices. We argue that people are naturally aware of the opportunity costs associated with delayed rewards, but pay less attention to those associated with taking smaller, sooner ones. We conclude by discussing implications for theory and policy. (shrink)

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.

Social dilemmas occur when individuals make choices that are in their own best interest but not in the interest of society as a whole. Intrapersonal dilemmas occur when people make choices that are in the best interest of themselves at the moment of choice, but not in the best interest of themselves in the long run. A number of writers have observed that we can usefully model this self-defeating behavior by treating each individual as an aggregate of selves which have (...) competing interests, like the individual selves in a population. We undertake to synthesize and extend these contributions, applying the theory of intrapersonal dilemmas to addiction and procrastination, and discuss how the concept of multiple selves can explain why people attempt to control their behavior by imposing costs or constraints on themselves in the future, and how it can also help us develop new strategies of (personal) behavior control.

The act-pattern model of altruism is primarily a brand-equity model, which holds that being altruistic can be traded for social benefits. This is a variant of the “selfish” altruism that Rachlin decries, with altruism being dictated by cold calculations. Moreover, personal and social “self-control” may not be as similar as Rachlin suggests – although we have good (biological) reasons to sacrifice the interests of our current selves in favour of our future selves, we have no such reason to sacrifice ourselves (...) for our neighbours. When we do sacrifice ourselves – giving in to true altruism – we will be repaid with extinction. (shrink)

The concept of behavioural mass provides one avenue for justifying (or making rational) the phenomenon of declining impatience, according to which decision makers put more value on delays that will occur in the near future than on those that will occur later.

Personal utilitarianism applies act-utilitarianism to the problem of individual choice. It is based on the view that the good life is achieved through maximizing the sum of individual measures of utility over a population. the population being the sequence of semi-autonomous selves from which the individual is composed. I begin by showing how our lives can usefully be partitioned into selves because the weights put on our various choice motives are constantly changing and, consequently, our preferences themselves concerning what we (...) should choose at any given time can also change from moment-to-moment. In particular, because we put disproportionate weight on our present needs relative to our future ones, we often become impatient and choose options that offer immediate gratification. I use concepts from game theory to describe multiple selves, and to discuss how strategic interactions between selves are possible, and then conclude by considering the practical problem of how to achieve the good life, or how can we get our selves to choose what is best for us in the long run.

This thesis argues that Dame Iris Murdoch’s writings portray a dialectical picture of morality that invites the reader to acknowledge the presence of evil and reflect upon the necessarily ‘opposing forces’ of good and evil. Murdoch’s engagement with both historical and contemporary discussions of evil is traced through close reading of both her published texts, including fiction and philosophy, and her unpublished and recently published texts and resources, including annotations, interviews and letters. These close readings are focused on the theological, (...) psychological and literary aspects of the contemporary problem of evil. The perspectives offered within this study all transcend the focus on goodness invited by Murdoch’s fiction and philosophy, thus challenging the biased perspective of scholars of the late-twentieth century who sought to elevate Murdoch’s good characters by drawing equations between her moral philosophy and her fiction. This study begins, first, by demonstrating how Murdoch’s writings engage with the problem of evil, with the theological attempt to reconcile goodness with the presence of evil and suffering in the world, by drawing on her allusions to the Book of Job and to the writings of Simone Weil and Dame Julian of Norwich, all of which assert the necessary presence of evil and suffering in the moral life. Second, I interrogate the inconsistencies between Murdoch’s fictional and philosophical pictures of evil to illustrate how her fictional and philosophical engagement with Saint Paul’s writings reveals that she adopted the same dialectical picture of morality for which she critiqued Jung in her moral philosophy. For her, Jung’s picture of morality merges aspects of dualism and monism, both of which, traditionally speaking, offer two countervailing ways in which to picture the moral life, where evil represents, respectively, either an independent moral force separate from the good or a failure to carry out the moral iii ideals of goodness. Third, I identify and develop a link between contemporary moral, psychological and sociological discourses on psychopathy and the evil characters, both male and female, within Murdoch’s novels: not only do her antagonists and demons, often called ‘enchanter’ figures by scholars, echo the psychopath’s moral psychology, but so too do her saintly figures. Such an ambiguous picture resonates with contemporary interpretations of psychopathy, such as those offered by Robert D. Hare, Kevin Dutton, or Simon Baron- Cohen, which highlight the complex role of compassion, empathy and emotion on the individual’s moral awareness, whether they are saintly or psychopathic. In the final chapter, I argue that Murdoch’s dialectical picture of morality is indebted to Blake, whose The Songs of Innocence and of Experience and The Marriage of Heaven and Hell illustrates the necessity of the ‘contrary’ pairs of innocence and experience, reason and passion, and good and evil. While Murdoch may praise goodness, her complex engagement with evil reveals a dialectical task for the moral agent in which they have to appreciate the complexity of the moral life, with its inherently ambiguous mixtures of emotion and rationality, the saintly and the psychopathic, and goodness and evil.
