Fresh teams are associated with original and multidisciplinary research

Area of Science:

• Scientific collaboration dynamics
• Research team composition
• Innovation in science

Background:

• Teamwork is central to modern scientific research.
• Team size impacts creativity, but the role of team 'freshness' is less understood.
• Defining and quantifying team freshness is crucial for understanding research impact.

Purpose of the Study:

• To quantify team freshness based on the absence of prior collaboration.
• To investigate the relationship between team freshness and research originality.
• To explore the link between team freshness and multidisciplinary impact.

Main Methods:

• Quantifying team freshness by analyzing the history of collaboration among members.
• Correlating team freshness metrics with measures of research originality and multidisciplinarity.
• Comparing the impact of new team members versus new collaboration relationships.

Main Results:

• Fresher teams, defined by lack of prior collaboration, produce more original and multidisciplinary papers.
• The positive effect of team freshness on originality and impact is amplified in larger teams.
• Freshness based on new team members is a stronger predictor of research originality and impact than new collaboration relationships.
• The career stage (freshness) of individual team members also positively correlates with paper originality and multidisciplinarity.

Conclusions:

• Introducing novel collaborations and team members enhances scientific originality and broad impact.
• Team composition, particularly the novelty of members and collaborations, is a key factor in driving scientific innovation.
• Leveraging team freshness, especially through new members, can be a strategy to boost research originality and interdisciplinary reach.
