Multidimensional Diversity and Research Impact in Political Science: What 50 Years of Bibliometric Data Tell Us

We examine the changing patterns of knowledge production and diffusion in political science over the past five decades using a dataset of over 200,000 SSCI-indexed research articles from 1970 to 2020. We analyze how author identity and team diversity influence research outputs and outcomes. The results show that historically excluded groups of scholars have gradually improved their representation and expanded their collaboration networks over time. Although the publication gaps are narrowing, obscured gaps in evaluation and citation practices persist. Research specialties with higher proportions of minority researchers tend to have lower average citation impacts. The least cited research specialties are largely studied by women and racial/ethnic minority scholars. Papers written by racial/ethnic minorities and Global South scholars are significantly less cited. However, collaborating with outgroup scholars can effectively overcome this citation gap. We also find that papers written by women receive more citations than those written by men, after controlling for journal prestige and research topics. Furthermore, when we limit our investigation to leading universities, citation gaps diminish. However, scholars of African descent continue to experience entrenched citation disadvantages even if they are affiliated with highly prestigious universities. This study provides multidimensional measurements to advance diversity debates and adds nuances to our understanding of opportunity structures in political science.
