Improve research through better data management and sharing plans

The United States government spends billions of dollars every year to support the best scientific research in the world. The novel and multidisciplinary data produced by these investments have historically remained unavailable to the broader scientific community and the public. This limits researchers’ ability to synthesize knowledge, make new discoveries, and ensure the credibility of research. But recent guidance from the Office of Science and Technology Policy (OSTP) represents a major step forward for making scientific data more available, transparent, and reusable. 

Federal agencies should take coordinated action to ensure that data sharing policies created in response to the 2022 Nelson memo incentivize high-quality data management and sharing plans (DMSPs), include robust enforcement mechanisms, and implement best practices in supporting a more innovative and credible research culture. 


The 2022 OSTP memorandum “Ensuring Free, Immediate, and Equitable Access to Federally Funded Research” (the Nelson memo) represents a significant step toward opening up not only the findings of science but its materials and processes as well. By including data and related research outputs as items that should be publicly accessible, defining “scientific data” to include “material… of sufficient quality to validate and replicate research findings” (emphasis added), and specifying that agency plans should cover “scientific data that are not associated with peer-reviewed scholarly publications,” this guidance has the potential to greatly improve the transparency, equity, rigor, and reusability of scientific research.

Yet while the 2022 Nelson memo provides a crucial foundation for open, transparent, and reusable scientific data, preliminary review of agency responses reveals considerable variation on how access to data and research outputs will be handled. Agencies vary by the degree to which policies will be reviewed and enforced and by the degree of specificity by which they define data as being materials needed to “validate and replicate” research findings. Finally, they could and should go further in including plans to fully support a research ecosystem that supports cumulative scientific evidence by enabling the accessibility, discoverability, and citation of researchers’ data sharing plans themselves.


To better incentivize quality and reusability in data sharing, agencies should: 

To better ensure compliance and comprehensive availability, agencies should:
