Scientific Integrity Act This bill requires, subject to Freedom of Information Act disclosure restrictions and privacy requirements, federal agencies that fund or conduct scientific research to: (1) promote and maximize the communication and open exchange of scientific data and findings to other agencies, policymakers, and the public; and (2) prevent the suppression or distortion of such data and findings. The bill amends the America COMPETES Act to require federal agencies that fund or conduct scientific research to develop and enforce a scientific integrity policy and submit it to Congress and the Office of Science and Technology Policy (OSTP). A scientific integrity policy must, at a minimum, ensure that scientific conclusions are not made based on political considerations. It must be made available to the public on agency websites and be disseminated to each new agency employee and contractor. Agencies must also develop and require training on the policy for its employees and contractors. The OSTP shall enter into an agrement with the National Academy of Public Administration to study the appropriateness of scientific integrity policies.
