Investigating the division of scientific labor using the Contributor Roles Taxonomy (CRediT)

Authors : Vincent Larivière, David Pontille, Cassidy R. Sugimoto

Contributorship statements were introduced by scholarly journals in the late 1990s to provide more details on the specific contributions made by authors to research papers.

After more than a decade of idiosyncratic taxonomies by journals, a partnership between medical journals and standards organizations has led to the establishment, in 2015, of the Contributor Roles Taxonomy (CRediT), which provides a standardized set of 14 research contributions.

Using the data from Public Library of Science (PLOS) journals over the 2017–2018 period (N = 30,054 papers), this paper analyzes how research contributions are divided across research teams, focusing on the association between division of labor and number of authors, and authors’ position and specific contributions.

It also assesses whether some contributions are more likely to be performed in conjunction with others and examines how the new taxonomy provides greater insight into the gendered nature of labor division. The paper concludes with a discussion of results with respect to current issues in research evaluation, science policy, and responsible research practices.

Contributorship and division of labor in knowledge production

Scientific authorship has been increasingly complemented with contributorship statements. While such statements are said to ensure more equitable credit and responsibility attribution, they also provide an opportunity to examine the roles and functions that authors play in the construction of knowledge and the relationship between these roles and authorship order.

Drawing on a comprehensive and multidisciplinary dataset of 87,002 documents in which contributorship statements are found, this paper examines the forms that division of labor takes across disciplines, the relationships between various types of contributions, as well as the relationships between the contribution types and various indicators of authors’ seniority.

It shows that scientific work is more highly divided in medical disciplines than in mathematics, physics and disciplines of the social sciences, and that, with the exception of medicine, the writing of the paper is the task most often associated with authorship.

The results suggest a clear distinction between contributions that could be labelled as ‘technical’ and those that could be considered ‘conceptual’: While conceptual tasks are typically associated with authors with higher seniority, technical tasks are more often performed by younger scholars.

Finally, results provide evidence of a u-shaped relationship between extent of contribution and author order: In all disciplines, first and last authors typically contribute to more tasks than middle authors.

The paper concludes with a discussion of the implications of the results for the reward system of science.
