How well do laboratory-derived estimates of time preference predict real-world behaviors? Comparisons to four benchmarks.

A large literature implicates time preference (i.e., how much an outcome retains value as it is delayed) as a predictor of a wide range of behaviors, because most behaviors involve sooner and delayed consequences.

Are future selves treated like others? Comparing determinants and levels of intrapersonal and interpersonal allocations.

People often make tradeoffs between current and future benefits. Some research frameworks suggest that people treat the future self as if it were another person, subordinating future needs to current ones just as they might subordinate others' needs to their own. Although people make similar choices for future selves and others in some contexts, it remains unclear whether these behaviors are governed by the same decision policies.

An empirically-derived taxonomy of moral concepts.

We propose that methods from the study of category-based induction can be used to test the descriptive accuracy of theories of moral judgment. We had participants rate the likelihood that a person would engage in a variety of actions, given information about a previous behavior. From these likelihood ratings, we extracted a hierarchical, taxonomic model of how moral violations relate to each other (Study 1).

What's wrong with using steroids? Exploring whether and why people oppose the use of performance enhancing drugs.

The use of performance enhancing drugs (PEDs) elicits widespread normative opposition, yet little research has investigated what underlies these judgments. We examine this question comprehensively, across 13 studies. We first test the hypothesis that opposition to PED use cannot be fully accounted for by considerations of fairness.

Personal change and the continuity of the self.

Five studies explore how anticipating different types of personal change affects people's perceptions of their own self-continuity. The studies find that improvements are seen as less disruptive to personal continuity than worsening or unspecified change, although this difference varies in magnitude based on the type of feature being considered. Also, people's expectations and desires matter.

Beliefs About the Causal Structure of the Self-Concept Determine Which Changes Disrupt Personal Identity.

Personal identity is an important determinant of behavior, yet how people mentally represent their self-concepts and their concepts of other people is not well understood. In the current studies, we examined the age-old question of what makes people who they are. We propose a novel approach to identity that suggests that the answer lies in people's beliefs about how the features of identity (e.

Connecting cognition and consumer choice.

We describe what can be gained from connecting cognition and consumer choice by discussing two contexts ripe for interaction between the two fields. The first-context effects on choice-has already been addressed by cognitive science yielding insights about cognitive process but there is promise for more interaction. The second is learning and representation in choice where relevant theories in cognitive science could be informed by consumer choice, and in return, could pose and answer new questions.

Are artworks more like people than artifacts? Individual concepts and their extensions.

This paper examines people's reasoning about identity continuity (i.e., how people decide that a particular object is the same object over time) and its relation to previous research on how people value one-of-a-kind artifacts, such as artwork.

Selfless giving.

In four studies, we show that people who anticipate more personal change over time give more to others. We measure and manipulate participants' beliefs in the persistence of the defining psychological features of a person (e.g.

Predicting premeditation: future behavior is seen as more intentional than past behavior.

People's intuitions about the underlying causes of past and future actions might not be the same. In 3 studies, we demonstrate that people judge the same behavior as more intentional when it will be performed in the future than when it has been performed in the past. We found this temporal asymmetry in perceptions of both the strength of an individual's intention and the overall prevalence of intentional behavior in a population.

The mismeasure of morals: antisocial personality traits predict utilitarian responses to moral dilemmas.

Researchers have recently argued that utilitarianism is the appropriate framework by which to evaluate moral judgment, and that individuals who endorse non-utilitarian solutions to moral dilemmas (involving active vs. passive harm) are committing an error. We report a study in which participants responded to a battery of personality assessments and a set of dilemmas that pit utilitarian and non-utilitarian options against each other.

The Costs and Benefits of Calculation and Moral Rules.

There has been a recent upsurge of research on moral judgment and decision making. One important issue with this body of work concerns the relative advantages of calculating costs and benefits versus adherence to moral rules. The general tenor of recent research suggests that adherence to moral rules is associated with systematic biases and that systematic cost-benefit analysis is a normatively superior decision strategy.

Psychological connectedness and intertemporal choice.

People tend to attach less value to a good if they know a delay will occur before they obtain it. For example, people value receiving $100 tomorrow more than receiving $100 in 10 years. We explored one reason for this tendency (due to Parfit, 1984): In terms of psychological properties, such as beliefs, values, and goals, the decision maker is more closely linked to the person (his or her future self) receiving $100 tomorrow than to the person receiving $100 in 10 years.

Principled moral sentiment and the flexibility of moral judgment and decision making.

Three studies test eight hypotheses about (1) how judgment differs between people who ascribe greater vs. less moral relevance to choices, (2) how moral judgment is subject to task constraints that shift evaluative focus (to moral rules vs. to consequences), and (3) how differences in the propensity to rely on intuitive reactions affect judgment.

Representation over time: the effects of temporal distance on similarity.

Similarity is central in human cognition, playing a role in a wide range of cognitive processes. In three studies, we demonstrate that subjective similarity may change as a function of temporal distance, with some events seeming more similar when considered in the near future, while others increase in similarity as temporal distance increases. Given the ubiquity of inter-temporal thought, and the fundamental role of similarity, these results have important implications for cognition in general.

Are morally motivated decision makers insensitive to the consequences of their choices?

Is morally motivated decision making different from other kinds of decision making? There is evidence that when people have sacred or protected values (PVs), they reject trade-offs for secular values (e.g., "You can't put a price on a human life") and tend to employ deontological rather than consequentialist decision principles.
