Defining the role of cognitive distance in the peer review process with an explorative study of a grant scheme in infection biology

The aim of this article is twofold: (1) to provide a methodology for measurement of cognitive distance between researchers and (2) to explore the role of cognitive distance on the results of peer review processes. Cited references and the content of articles are used to represent their respective scientific knowledge bases. Based on the two different approaches-Author-Bibliographic Coupling analysis and Author-Topic analysis-we apply the methodology on a recent competition for grants from the Swedish Strategic Foundation. Results indicate that cognitive distances between applicants and reviewers might influence peer review results, but that the impact is to some extent at the unexpected end. The main contribution of this article is the elaboration on the relevance of the concept of cognitive distance to the issue of research evaluation in general, and especially in relation to peer review as a model used in grant decisions.
