By analyzing a unique dataset of more than 270,000 scientists, we discovered substantial gender differences in scientific collaborations. While men are more likely to collaborate with other men, women are more egalitarian. This is consistently observed over all fields and regardless of the number of collaborators a scientist has. The only exception is observed in the field of engineering, where this gender bias disappears with increasing number of collaborators. We also found that the distribution of the number of collaborators follows a truncated power law with a cut-off that is gender dependent and related to the gender differences in the number of published papers. Considering interdisciplinary research, our analysis shows that men and women behave similarly across fields, except in the case of natural sciences, where women with many collaborators are more likely to have collaborators from other fields.
通过分析一个包含超过27万名科学家的独特数据集，我们发现了科学合作中存在显著的性别差异。男性更倾向于与其他男性合作，而女性则更平等。在所有领域都能持续观察到这一现象，且与科学家的合作者数量无关。唯一的例外出现在工程领域，随着合作者数量的增加，这种性别偏见会消失。我们还发现，合作者数量的分布遵循截断幂律，其截止点与性别有关，并且与发表论文数量的性别差异相关。考虑到跨学科研究，我们的分析表明，除了在自然科学领域外，男性和女性在各个领域的行为相似，在自然科学领域，有许多合作者的女性更有可能有来自其他领域的合作者。
