A Meta-Analysis of Gender Proportionality Effects on Job Performance

gender-equality-1977912_1920 (1)[We’re pleased to welcome authors Jeremy D. Mackey of Auburn University, Philip L. Roth of Clemson University, Chad H. Van Iddekinge of Florida State University, and Lynn A Mcfarland of the University of South Carolina. They recently published an article in Group & Organization Management entitled “A Meta-Analysis of Gender Proportionality Effects on Job Performance,” which is currently free to read for a limited time. Below, they discuss their motivations and findings:]

GOM_72ppiRGB_powerpointPhil Roth, Chad Van Iddekinge, Lynn McFarland, and I began working on our study entitled “A Meta-Analysis of Gender Proportionality Effects on Job Performance” because we wanted to examine whether gender proportionality (i.e., the percentage of females in an organization) affects females’ job performance relative to males’ job performance. Overall, we found weak effects of gender proportionality on job performance. Specifically, we found support for a no token effect perspective rather than a linear or curvilinear token effect perspective. Our findings are important because they challenge the prevailing wisdom of critical mass theory and the tokenism hypothesis. We hope our study stimulates additional research in this important area of inquiry.

The most challenging aspect of conducting our research was its scope. Research that examines gender effects on performance has affected numerous fields, including management, applied psychology, sociology, and criminal justice. Thus, it was a challenge to determine the appropriate scope for our study so our results could be generalizable. Ultimately, we included data from 158 independent studies that included a total of 101,071 respondents.

The most surprising finding from our study was the consistent lack of support for linear or curvilinear effects of gender proportionality on job performance across types of performance (i.e., overall subjective job performance, task performance, OCBs, and objective performance) and features of study designs. Overall, our findings were consistent for respondents from civilian or military organizations, whether single or multiple organizations were included in each sample, regardless of whether respondents had managerial or non-managerial jobs, whether there were traditional stereotypes of men’s work or women’s work for respondents’ jobs, regardless of administrative or research purposes for each study, despite whether each study was published or unpublished, and regardless of the year of publication of each study.

Despite our findings, we encourage future research to examine gender proportionality effects on job performance and other organizational outcomes because it is important to understand the conditions in which gender proportionality affects organizational outcomes and the types of outcomes that are affected by gender proportionality.
