A debate is raging in workplaces, schools, universities, and political and legal arenas: Is it better to ignore or acknowledge group differences? Multiculturalism, a pluralistic ideology, stresses recognizing and celebrating group differences, whereas color blindness, an assimilationist ideology, stresses ignoring or minimizing group differences. Both ideologies arguably advocate for equality, ...

Sex and ethnic group differences were examined on the operational composites and tests used to select applicants for U. S. Air Force officer commissioning programs and for pilot training. Results showed that large mean score differences in applicant samples were substantially reduced among the pilot trainees. Despite differences in test performance, there was no evidence of differential validit...

Stereotype formation may be based on the exaggeration of real group differences (category accentuation) or the misperception of group differences that do not exist (illusory correlation). This research sought to account for both phenomena with J. K. Kruschke's (1996, 2001, 2003) attention theory of category learning. According to the model, the features of majority groups are learned earlier th...

Research consistently demonstrates that sexual minority status is associated with increased risk of problematic substance use. Existing literature in this area has focused on group-specific minority stress factors (e.g., victimization and internalized heterosexism). However, no known research has tested the incremental validity of personality traits as predictors of substance use beyond identif...

A model of group decision-making is studied, in which one of two alternatives must be chosen. While group members differ in their valuations of the alternatives, everybody prefers some alternative to disagreement. Our model is distinguished by three features: private information regarding valuations, varying intensities in the preference for one outcome over the other, and the option to declare...

This paper explores the implications for labor market outcomes of systematic testing of applicants in the hiring process. A matching model in which productivity is a worker’s private information is used. Both wages and hiring rates are endogenous. A minority is defined as a group for whom the test is less precise in identifying individual productivity. Welfare and employment outcomes across var...
