How does prior experience influence team creativity? We address this question by examining the effects of task experience acquired directly and task experience acquired vicariously from others on team creativity in a product-development task. Across three laboratory studies, we find that direct...

People often make judgments about the ethicality of others' behaviors and then decide how harshly to punish such behaviors. When they make these judgments and decisions, sometimes the victims of the unethical behavior are identifiable, and sometimes they are not. In addition, in our uncertain...

Does desire for an outcome inflate optimism? Previous experiments have produced mixed results regarding the desirability bias, with the bulk of supportive findings coming from one paradigm--the classic marked-card paradigm in which people make discrete predictions about desirable or undesirable...

Our research is based on arguments that three different diversity sources in groups - agreeableness, openness, and ethnicity - might simultaneously possess separation properties that result in social categorization and variety properties that provide non-redundant and value-adding information...

In the decision-making literature, "advice" has typically been defined very restrictively, as a recommendation concerning which alternative the decision-maker should choose. The present paper examines decision-makers' reactions to this and three additional types of advice (a recommendation...

Prior research has demonstrated that individuals show decreasing levels of impatience as the delay of consumption gets longer (i.e., present-bias). We examine the psychological underpinnings of such present-biased preferences by conceptualizing timing decisions as part of a series of judgments....

We conducted two studies that investigated the role of leadership succession as a moderator of the relationship between LMX and turnover in organizations. In a sample of 330 employees in 45 veterinary hospitals, high-LMX employees were less likely to leave the organization prior to a succession...

In six experiments, we tested four explanations for the better/worse-than-average effect (B/WTA) by manipulating the number of items comprising the target or referent of direct comparison. A single-item target tended to be rated more extremely than a single-item or a multi-item referent...

Managers often must assess singular strategic options. Four studies of such assessments demonstrate a tunnel vision effect: Focal managerial options often are favored in an evidentially unjustifiable manner. Study 1 concerns new product development, and demonstrates that a prototype that has...

Research on information sharing in group decision-making has widely assumed a cooperative context and focused on the exchange of shared or unshared information in the hidden profile paradigm ([Stasser and Titus, 1985] and [Stasser and Titus, 1987]), neglecting the role of information importance....
