通过检查 1985 年至 2008 年间美国作者撰写的超过 250 万篇科学论文中作者的种族身份，我们发现相似种族的人共同创作的频率比他们在作者中所占比例所预测的要高。同质性越高，与在影响力较低的期刊上发表论文和引用次数越少相关。与此同时，作者分布在更多地点且参考文献列表更长的论文会在影响力更高的期刊上发表并获得更多引用。这些发现表明，通过影响因子和引用来衡量，作者种族、地点和参考文献的输入多样性可以带来更大的科学贡献。
By examining the ethnic identity of authors in over 2.5 million scientific papers written by US-based authors from 1985 to 2008, we find that persons of similar ethnicity coauthor together more frequently than predicted by their proportion among authors. The greater homophily is associated with publication in lower-impact journals and with fewer citations. Meanwhile, papers with authors in more locations and with longer reference lists get published in higher-impact journals and receive more citations. These findings suggest that diversity in inputs by author ethnicity, location, and references leads to greater contributions to science as measured by impact factors and citations.
