Sorry we're open, come in we're closed: different profiles in the perceived applicability of open science practices to completed research projects.

Open science is an increasingly important topic for research, politics and funding agencies. However, the discourse on open science is heavily influenced by certain research fields and paradigms, leading to the risk of generalizing what counts as openness to other research fields, regardless of its applicability. In our paper, we provide evidence that researchers perceive different profiles in the potential to apply open science practices to their projects, making a one-size-fits-all approach unsuitable. In a pilot study, we first systematized the breadth of open science practices. The subsequent survey study examined the perceived applicability of 13 open science practices across completed research projects in a broad variety of research disciplines. We were able to identify four different profiles in the perceived applicability of open science practices. For researchers conducting qualitative-empirical research projects, comprehensively implementing the breadth of open science practices is tendentially not feasible. Further, research projects from some disciplines tended to fit a profile with little opportunity for public participation. Yet, disciplines and research paradigms appear not to be the key factors in predicting the perceived applicability of open science practices. Our findings underscore the case for considering project-related conditions when implementing open science practices. This has implications for the establishment of policies, guidelines and standards concerning open science.
