Towards an inclusive Open Science: examining EDI and public participation in policy documents across Europe and the Americas

National, international and organizational Open Science (OS) policies are being formulated to improve and accelerate research through increased transparency, collaboration and better access to scientific knowledge. Yet, there is mounting concern that OS policies do not effectively capture the ethos of OS, and particularly its goal of making science more collaborative, inclusive and socially engaged. This study explores how OS is conceptualized in emerging OS policies and to what extent notions of equity, diversity and inclusion (EDI), as well as public participation are reflected in policy guidelines and recommendations. We use a qualitative document research approach to critically analyse 52 OS policy documents published between January 2020 and December 2022 in Europe and the Americas. Our results show that OS policies overwhelmingly focus on making research outputs publicly accessible, neglecting to advance the two aspects of OS that hold the key to achieving an equitable and inclusive scientific culture—namely, EDI and public participation. While these concepts are often mentioned and even embraced in OS policy documents, concrete guidance on how they can be promoted in practice is overwhelmingly lacking. Rather than advancing the openness of scientific findings first and promoting EDI and public participation efforts second, we argue that incentives and guidelines must be provided and implemented concurrently to advance the OS movement’s stated goal of making science open to all.
