Arguably, all judgments and decisions are made in 1 (or some combination) of 2 basic evaluation modes-joint evaluation mode (JE), in which multiple options are presented simultaneously and evaluated comparatively, or separate evaluation mode (SE), in which options are presented in isolation and...

Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to...

Consumers often behave differently than they would ideally like to behave. We propose that an anticipatory pain of paying drives tightwads to spend less than they would ideally like to spend. Spendthrifts, by contrast, experience too little pain of paying and typically spend more than they would...

Historical perspectives, as well as recent work in psychology, converge on the conclusion that human behavior is the product of two or more qualitatively different neural processes that operate according to different principles and often clash with one another. We describe a specific 'dual...

Standard economic models assume that the weight given to information from different sources depends exclusively on its diagnosticity. In this paper we study whether the same piece of information is weighted more heavily simply because it arose from direct experience rather than from observation....

Conflicts of interest can lead experts to give biased and corrupt advice. Although disclosure is often proposed as a potential solution to these problems, we show that it can have perverse effects. First, people generally do not discount advice from biased advisors as much as they should, even...

An influential line of thinking in behavioral science, to which the two authors have long subscribed, is that many of society’s most pressing problems can be addressed cheaply and effectively at the level of the individual, without modifying the system in which individuals operate. Along with,...

We analyze the offering, asking, and granting of help or other benefits as a three-stage game with bilateral private information between a person in need of help and a potential help-giver. Asking entails the risk of rejection, which can be painful: since unawareness of the need can no longer be...
