Team effectiveness and group performance are often defined by standards set by domain experts. Professional musicians consistently report that sound output is the most important standard for evaluating the quality of group performance in the domain of music. However, across six studies, visual...

Previous research suggests people firmly value moral standards. However, research has also shown that various factors can compromise moral behavior. Inspired by the recent financial turmoil, we investigate whether financial deprivation might shift people’s moral standards and consequently...

Incorporating input from others can enhance decision quality, yet often people do not effectively utilize advice. We propose that greater power increases the propensity to discount advice, and that a key mechanism explaining this effect is elevated confidence in one’s judgment. We investigate...

This paper presents three studies that demonstrate people’s preference for a large percentage of a small subset over a small percentage of a large subset, when the net overall quantity is equated. Because the division of a set into subsets is often arbitrary, this preference represents a...

Low numerical probabilities tend to be directionally ambiguous, meaning they can be interpreted either positively, suggesting the occurrence of the target event, or negatively, suggesting its non-occurrence. High numerical probabilities, however, are typically interpreted positively. We argue...

Losses loom larger than gains. The typical interpretation of loss aversion involves a subjective value-based asymmetry between gains and losses, with individuals expecting losses to be more painful than gains of equal size to be pleasurable. This paper reveals a novel, subjective...

Here we investigated whether, given equivalent supporting evidence, we judge self-selected hypotheses differently from those selected by an external source. On each trial of a probabilistic reasoning task requiring no retrieval from memory, participants rated the probability of a focal...
