Great minds think alike, or do they often differ? Research topic overlap and the formation of scientific teams
作者：
Highlights：
• There is an inverted-U relationship between topic overlap and future collaboration.
• Collaboration is most likely at low-to-moderate levels of topic overlap.
• Topic overlap between researchers and communities is substantially lower than their respective self-similarity.
• The curvilinear relationship between topic overlap and collaboration is robust of gender and intra/interdisciplinarity.
• The curvilinear relationship between topic overlap and collaboration varies by discipline.
