Scholarship on the behavioural immune system suggests that people who perceive themselves as more susceptible to illnesses are more sensitive to disgust, providing an evolutionary advantage to avoid pathogenic stimuli. This sensitivity causes those with greater perceived susceptibility to be biased against outgroup members and avoid those with dissimilar immunological histories. However, the lack of a quantitative review forces researchers to derive arguments from specific empirical observations, rather than holistically drawing from averaged effects across studies. Researchers may over-rely on studies that produced atypical results, causing biases in research on perceived infectability, germ aversion, disgust and outgroup perceptions. To resolve this tension in the literature, we perform a meta-analysis of 74 sources. Our meta-analytic results demonstrate that perceived infectability produces small relations with disgust and non-significant relations with outgroup perceptions, whereas a construct commonly conflated with perceived infectability, germ aversion, produces larger relations with these two outcomes. A meta-analytic structural equation model demonstrates that the indirect effect of perceived infectability on outgroup perceptions via the mediator of disgust is not statistically significant. These findings indicate that, while perceived infectability relates to disgust, the construct does not relate to perceptions of outgroup members, counter to scholarship on the behavioural immune system.

Purpose This study explores subordinate autonomy as a mediator in the relationship between ethical leadership and subordinate organizational citizenship behavior (OCB) and examines how subordinate Machiavellianism influences this relationship. By exploring these dynamics, this study aims to provide a nuanced understanding of the social-cognitive mechanisms and boundary conditions that influence how ethical leadership fosters OCB within organizations.
Design/methodology/approach This study examines the model using social cognitive theory (SCT) and dyadic data. The authors use partial least squares structural equation modeling to test the hypotheses, examining the mediating effect of autonomy and the moderating effect of Machiavellianism on the relationship between ethical leadership and organizational citizenship behavior.
Findings Results indicate that perceptions of autonomy fully mediate the relationship between ethical leadership and supervisor-rated OCB. Additional results showed that high subordinate Machiavellianism strengthens the positive relationship between autonomy and OCB.
Originality/value The authors extend the SCT application by investigating mechanisms through which subordinates engage in OCB in response to ethical leadership. By examining Machiavellianism, they also provide a nuanced understanding of the conditions under which ethical leadership fosters enhanced OCB, thereby contributing to the literature on the bright side of dark traits.

In this timely piece, we delve into the potential downside of remote work: workaholism. We explore the nuanced relationship between remote work environments and workaholic behavior based on data we collected from over 150 remote work professionals who transitioned from office to remote work during COVID-19 restrictions.
Our findings show how highly conscientious employees in low situational strength environments may be particularly susceptible to overworking and burning out while working remotely. We also outline practical strategies managers can implement to support their teams and prevent workaholism from taking hold.

Researchers have shown great interest in the creation of rehabilitation programs using mixed reality (MR), which includes both augmented reality (inclusion of virtual elements in a real environment) and augmented virtuality (inclusion of real elements in a virtual environment). Due to its recent development and systematic limitations of associated studies (e.g., small sample sizes), many pivotal research questions for the study of MR rehabilitation (MRR) programs remain unanswered, and the current article seeks to answer these questions via a meta-analysis and systematic literature review. Our random-effects meta-analysis, including 29 studies, showed that MRR programs produce significant improvements in users' outcomes, and they were significantly more effective than alternative rehabilitation programs when matched for duration. It also demonstrated that there was not a significant effect regarding all studied characteristics of MRR programs, including the incorporation of game elements, use of head-mounted displays, and task-technology fit. Our systematic literature review identified the most studied types of MRR programs, and it revealed that the most common research designs are the least methodologically robust (e.g., single group post-test only design). Our discussion suggests that MRR programs are still in the earliest stage of research, and the current results are encouraging for future development. Because none of our studied characteristics altered the effectiveness of MRR programs, we argue that characteristics that are generally consistent across all MRR programs are the drivers of their effectiveness, which can be categorized as fidelity and motivational characteristics.
