Union of Concerned Scientists - "A strong democracy depends on transparency, accountability, and trust in the government to make evidence-based decisions that protect public health and the environment. Federal scientists play an important role in fulfilling this mandate by providing critical expertise to decision makers and the American people. But sometimes, political or commercial forces interfere with this process, preventing scientific information from reaching those who need it. Strong policies governing external communications serve as the first line of defense against such abuses. Our 2013 report, Grading Government Transparency, looks at the policies governing scientists' communications through both traditional and social media at 17 federal agencies, evaluating the policies in a variety of categories and summarizing each evaluation with a letter grade."
