Dissertation acknowledgments and subsequent collaboration among business scholars
This study analyzes 1,343 U.S.-trained business scholars to demonstrate that the frequency and volume of family acknowledgments in dissertations are positively associated with subsequent new coauthorship ties across early and mid-career stages, thereby expanding the relational data available for studying scientific careers beyond traditional publication records.

Science is often imagined as a solitary pursuit, a lone mind wrestling with a problem until a solution appears. Yet the reality of modern research is deeply social. Before a paper is ever published, a researcher must find partners, build trust, and navigate the uncertainties of a project that might fail. These relationships are the invisible scaffolding of discovery, but they rarely leave a trace in the official records of science. Publication databases list the authors who signed the final paper, but they do not record the friends who offered encouragement, the family members who managed household duties to allow for late-night work, or the mentors who provided crucial introductions. Understanding how these hidden networks of support shape a scientist's career requires looking beyond the final product to the moments of preparation that made it possible.
Researchers have long known that the people we thank in our work matter, but they have struggled to measure exactly how that gratitude translates into future success. A dissertation, the final project a student completes to earn a doctorate, offers a rare window into this hidden world. At the moment of graduation, a student writes an acknowledgment section, a text where they list the people who helped them. This text captures a snapshot of their support network at a specific career boundary, before their professional life has fully unfolded. By treating these words as data, a team of scholars set out to see if the way a student thanked their supporters could predict how they would collaborate with others in the decade that followed.
The study focused on 1,343 business scholars who earned their doctorates in the United States. The researchers gathered the full text of their dissertations and linked them to the scholars' subsequent careers, tracking their publications and co-authorship patterns for ten years after graduation. They divided this decade into three periods: the first three years, the middle three years, and the final four years. For each period, they counted how many new partners a scholar worked with and how often they returned to work with old partners. They then compared these career patterns against the specific details found in the dissertation acknowledgments. They looked at the number of people thanked, the total volume of words used, and how the text was distributed among different mentors. They also developed a way to measure whether a student concentrated their thanks on a few highly influential mentors or spread it more evenly across their network.
The results revealed a clear and consistent pattern regarding family. The more family members a scholar thanked in their dissertation, the more likely they were to form new collaborations and maintain existing ones in the years that followed. This association held true across all three time periods. For instance, in the first three years after graduation, each additional family member mentioned was linked to a measurable increase in new partnerships. This relationship grew stronger over time; by the seventh to tenth year, the connection between family acknowledgments and new collaboration was even more pronounced. The volume of text dedicated to family also mattered. Scholars who wrote more words about their family support tended to have more new co-authors in the years following their degree. These findings suggest that the private, non-academic support system a researcher relies on is not just a background detail but is deeply intertwined with their ability to build and sustain professional networks.
The picture was more complex when it came to academic mentors. While thanking family showed a steady link to future collaboration, the number of mentors thanked or the amount of text dedicated to them did not show the same uniform pattern. In some time periods, thanking more mentors was linked to more new partnerships, but in others, the link was weak or non-existent. The researchers also examined how students distributed their thanks among mentors. They looked at whether a student focused their gratitude on a single powerful figure or spread it out. They found that in the middle years of a career, specifically between the fourth and sixth years, scholars whose acknowledgment patterns changed significantly when weighted by their mentors' influence were more likely to form new partnerships. This suggests that the way a student navigates their academic hierarchy at graduation might influence their ability to expand their network later, though the relationship is less direct than the one seen with family support.
The study did not claim to prove that thanking family causes a scholar to be more successful. The researchers were careful to note that these are associations, not proof of cause and effect. It is possible that a supportive family environment fosters a personality type that is naturally more collaborative, or that the resources provided by family allow a scholar to take risks that lead to new partnerships. The data simply shows that the record of gratitude left at graduation is a reliable marker for the collaborative patterns that emerge later. The findings also did not suggest that a longer acknowledgment list is always better, or that thanking a famous mentor guarantees success. Instead, the work highlights that the social environment surrounding a researcher remains visible in their later career choices. The people who helped a scholar complete their most demanding project are often the same people whose support echoes in the partnerships they form for the rest of their lives.
