Doctoral students who work with an advisor early in their career earn more citations and better jobs than the students who follow them.

The Takeaway
Ph.D. candidates joining a new lab often fear that their advisor lacks the influence to help them succeed. This research shows that the opposite is true, as early students of a professor secure unique intellectual niches and more focused mentorship. Later students may have more funding and a famous advisor, but they struggle to replicate the birth order advantage of their academic siblings. This effect persists across disciplines and is not explained by the advisor's total resources or status. For a long-term career in science, the open territory of a young faculty member is more valuable than the prestige of an established star.
From the abstract
This paper investigates mechanisms underlying scientific stratification in the transition from elite to mass science. Existing scholarship has examined stratification through the Matthew effect framework, but this approach is increasingly limited as mass, team-based research becomes dominant. While scientists now share institutions and lineages, substantial career outcome differences remain unexplained. We propose integrating demographic concepts into science studies. Drawing parallels between b
