The image above graphically depicts the citation networks of two federal agencies – the Environmental Protection Agency/EPA (on right) and Health and Human Services/HHS (middle far left), comparing their use of science in policy decision-making. The pale blue circles represent U.S. federal Regulatory Impact Analyses (RIAs) conducted between 2008 and 2012 that cite scientific research in justifying an agency's policy decisions. Each red circle represents a scientific publication cited in one or more RIAs. Computational social scientist Bruce Desmarais and policy expert John Hird are using network analysis to analyze the use of science in regulatory policymaking. The network web of EPA above not only cites far more science than HHS, the science is more inter-connected and often serves multiple regulations. Learn more.
