Prior work finds a diversity paradox: Diversity breeds innovation, yet underrepresented groups that diversify organizations have less successful careers within them. Does the diversity paradox hold for scientists as well? We study this by utilizing a near-complete population of ∼1.2 million US doctoral recipients from 1977 to 2015 and following their careers into publishing and faculty positions. We use text analysis and machine learning to answer a series of questions: How do we detect scientific innovations? Are underrepresented groups more likely to generate scientific innovations? And are the innovations of underrepresented groups adopted and rewarded? Our analyses show that underrepresented groups produce higher rates of scientific novelty. However, their novel contributions are devalued and discounted: For example, novel contributions by gender and racial minorities are taken up by other scholars at lower rates than novel contributions by gender and racial majorities, and equally impactful contributions of gender and racial minorities are less likely to result in successful scientific careers than for majority groups. These results suggest there may be unwarranted reproduction of stratification in academic careers that discounts diversity's role in innovation and partly explains the underrepresentation of some groups in academia.
多样性促进创新,但使组织多样化的代表性不足群体在其中的职业发展却不太成功。多样性悖论是否也适用于科学家?我们通过利用 1977 年至 2015 年期间约 120 万名美国博士研究生的近乎完整的人口数据,并跟踪他们在出版和教职方面的职业发展,来研究这个问题。我们使用文本分析和机器学习来回答一系列问题:我们如何发现科学创新?代表性不足的群体更有可能产生科学创新吗?代表性不足群体的创新是否被采纳和得到回报?我们的分析表明,代表性不足的群体产生了更高的科学新颖性的比率。然而,他们的新颖贡献被低估和忽视:例如,性别和少数族裔的新颖贡献被其他学者采用的比例低于性别和多数族裔的新颖贡献,性别和少数族裔同样有影响力的贡献获得成功的科学职业的可能性也低于多数群体。这些结果表明,学术职业中可能存在不合理的分层现象,这种现象忽视了多样性在创新中的作用,部分解释了一些群体在学术界代表性不足的原因。
