This meta-analysis of 260 independent samples assessed the effects of diversity training on 4 training outcomes over time and across characteristics of training context, design, and participants. Models from the training literature and psychological theory on diversity were used to generate theory-driven predictions. The results revealed an overall effect size (Hedges g) of .38 with the largest effect being for reactions to training and cognitive learning; smaller effects were found for behavioral and attitudinal/affective learning. Whereas the effects of diversity training on reactions and attitudinal/affective learning decayed over time, training effects on cognitive learning remained stable and even increased in some cases. While many of the diversity training programs fell short in demonstrating effectiveness on some training characteristics, our analysis does reveal that successful diversity training occurs. The positive effects of diversity training were greater when training was complemented by other diversity initiatives, targeted to both awareness and skills development, and conducted over a significant period of time. The proportion of women in a training group was associated with more favorable reactions to diversity training. Implications for policy and directions for future research on diversity training are discussed. (PsycINFO Database Record

Despite a growing body of literature on diversity and firm performance, our review of research across fields, theoretical traditions, and levels of analysis suggests that the relationship is not a simple one. However, we attempt to integrate theory and research from macro and micro research domains into one perspective on the firm-level performance effects of diversity. We review the results of research on diversity and firm performance based on the level of analysis at which diversity was examined, highlighting what we know and do not know about this relationship, and why a new approach to research in this area is needed. To set a future research agenda, we introduce a dynamic capabilities framework for studying diversity and firm performance, identifying a subset of capabilities through which we would expect firms to extract benefit (or loss) from diversity and articulate the underlying mechanisms through which such effects are likely to occur. By putting forth this framework, our goal is to offer an integrative, process-based perspective for understanding value creation and capture as it pertains to diversity, and encouraging a more systemic approach to the study of diversity and firm performance.

In late 2014, a series of highly publicized police killings of unarmed Black male civilians in the United States prompted large-scale social turmoil. In the current review, we dissect the psychological antecedents of these killings and explain how the nature of police work may attract officers with distinct characteristics that may make them especially well-primed for negative interactions with Black male civilians. We use media reports to contextualize the precipitating events of the social unrest as we ground our explanations in theory and empirical research from social psychology and industrial and organizational (I/O) psychology. To isolate some of the key mechanisms at play, we disentangle racial bias (e.g., stereotyping processes) from common characteristics of law enforcement agents (e.g., social dominance orientation), while also addressing the interaction between racial bias and policing. By separating the moving parts of the phenomenon, we provide a more fine-grained analysis of the factors that may have contributed to the killings. In doing so, we endeavor to more effectively identify and develop solutions to eradicate excessive use of force during interactions between "Black" (unarmed Black male civilians) and "Blue" (law enforcement).

In 2 studies, we investigated how groups with strong divisions may, paradoxically, help members to cope with injustice. We tested our theoretical predictions using a survey methodology and data from 57 (Study 1) and 36 (Study 2) workgroups across different industries. Consistent with our hypotheses, we found that group faultlines weakened the positive relationship between perceived interpersonal injustice and psychological distress. Cooperative behaviors within subgroups mediated the interactive effect of faultlines and injustice with psychological distress.
