The Department of Social and Decision Sciences (SDS) is an interdisciplinary academic department within the Dietrich College of Humanities and Social Sciences at Carnegie Mellon University. The Department of Social and Decision Sciences is headquartered in Porter Hall in Pittsburgh, Pennsylvania and is led by Department Head Linda C. Babcock. SDS has a world-class reputation for research and education programs in decision-making in public policy, economics, management, and the behavioral social sciences.
The Department of Social Sciences grew out of the social science programs in the Margaret Morrison Carnegie College. The formal department was established in 1976, as part of the Dietrich College of Humanities and Social Sciences under Dean John Patrick Crecine with approval from Heinz College Dean Otto Davis, which previously housed the program. The department was staffed by political scientists, sociologists, and economists from within the Dietrich College, the Heinz College, and the Tepper School of Business. In the 1980s, the department was led by Patrick D. Larkey and developed the undergraduate information systems program which became a huge success, eventually being spun off into an independent interdisciplinary program in the Dietrich College. In 1985, Robyn Dawes joined the department and began to re-focus it into its current form and expertise in behavioral decision-making and caused it to be renamed as the Department of Social and Decision Sciences. Carnegie Mellon's Institute for Politics and Strategy was spun off of the department in 2015.
