受多样性的社会和经济效益的启发，我们分析了超过900万篇论文和600万名科学家，研究研究影响力与五类多样性之间的关系：种族，学科，性别，隶属关系和学术年龄。使用随机基线模型，我们建立了在种族，性别和从属关系的同质性的存在。然后，我们研究了多样性对科学影响的影响，反映在引文中。值得注意的是，在所考虑的类别中，种族多样性与科学影响力的相关性最强。为了进一步分离种族多样性的影响，我们使用了随机基线模型，并再次发现了多样性和影响力之间的明确联系。为了进一步支持这些发现，我们使用粗化精确匹配来比较种族多样性论文和科学家与紧密匹配的对照组的科学影响。在这里，我们发现种族多样性使论文的影响力增加了10.63%，使科学家的影响力增加了47.67%。
Inspired by the social and economic benefits of diversity, we analyze over 9 million papers and 6 million scientists to study the relationship between research impact and five classes of diversity: ethnicity, discipline, gender, affiliation, and academic age. Using randomized baseline models, we establish the presence of homophily in ethnicity, gender and affiliation. We then study the effect of diversity on scientific impact, as reflected in citations. Remarkably, of the classes considered, ethnic diversity had the strongest correlation with scientific impact. To further isolate the effects of ethnic diversity, we used randomized baseline models and again found a clear link between diversity and impact. To further support these findings, we use coarsened exact matching to compare the scientific impact of ethnically diverse papers and scientists with closely-matched control groups. Here, we find that ethnic diversity resulted in an impact gain of 10.63% for papers, and 47.67% for scientists.
