Which amendment was enacted to allow public access to research data generated with public funds?

The amendment that allows public access to research data generated with public funds is the Shelby amendment. This legislation specifically mandates that research results funded by federal government grants be made available to the public. The intent of the Shelby amendment is to enhance transparency and accountability in research, ensuring that taxpayers can access information that is derived from their funding.

In contrast, the other amendments listed do not focus on public access to research data. The Welsh-Healy amendment, for example, involves regulations related to public works and the payment of prevailing wages, and the Densworth and Jordan-Hill amendments pertain to different legislative contexts. Therefore, understanding the Shelby amendment's focus on public access to federally funded research data is essential for recognizing its significance and application in the context of government-funded research initiatives.
