Social and Decision Sciences (Carnegie Mellon University)

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 John H. Miller.

History
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 and from the Heinz College and 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.

Education
The department runs highly regarded undergraduate bachelor of science programs in Decision Science, Policy and Management, and International Relations and Politics as well as a minor in Policy and Management. Further, SDS is a partner in various interdisciplinary undergraduate programs such as the Sociology minor, Environmental Policy program, and the Davis Quantitative Social Science Scholars program. At the master's degree level, SDS partners with several other colleges and departments for the Master of Information Technology Strategy program and the Engineering and Technology Innovation Management program. The graduate PhD program allows doctoral students options in Social and Decision Sciences, Behavioral Decision Research (BDR), Strategy, Entrepreneurship, and Technological Change (SETchange), Technological Change and Entrepreneurship as well as a joint PhD in Behavioral Decision Research and Psychology with the Department of Psychology. All students are trained in policy analysis and research methods. The information systems program at Carnegie Mellon is closely associated with the SDS department due to the program being spun off from the department in the late 1990s.

Research
The department's primary strength lies in interdisciplinary research, particularly in the intersection of politics and sociology with economics, psychology and human decision making. Statistics, microeconomics, rational decision theory and game theory are among the many areas of specialization. SDS faculty are very involved in interdisciplinary research throughout the university, and are drawn from fields as diverse as economics, psychology, sociology, history, management science, and political science. SDS is affiliated with several labs, institutes, and centers:
 * Center for Behavioral Decision Research
 * Center for International Relations and Politics
 * Center for Risk Perception and Communication
 * Dynamic Decision Making Laboratory

As part of the Center for Behavioral Decision Research, SDS manages the Data Truck and the Carnegie Mellon Research Cafe. The Data Truck is a mobile behavioral science lab and the Research Cafe is a cafe located in downtown Pittsburgh and is designed to perform behavioral research outside of the student population on the main Carnegie Mellon Pittsburgh campus where the SDS labs are located.

Rankings
In 2006, an Institute for Operations Research and the Management Sciences study gave four of five stars to the graduate program in prescriptive decision making and five stars in descriptive decision making. These two ratings tied the department for first place among decision science programs in the United States with Duke University and the University of Pennsylvania.

Faculty
SDS is home to some of the world's top faculty in the fields of decision science, decision support systems, behavioral economics, organizational behavior, and risk analysis. Some notable faculty members have included Baruch Fischhoff, Paul Fischbeck, Robyn Dawes, George Loewenstein, Jennifer Lerner, Kathleen Carley, David Krackhardt, Steven Klepper, Linda Babcock, Lee Branstetter, David A. Hounshell, William Keech, Mark Kamlet, Roberto Weber, Economics Nobel Laureate Herbert A. Simon, Jendayi Frazer, Kiron Skinner, Sara Kiesler, John Patrick Crecine, Cristina Bicchieri, Joseph Born Kadane, Patrick D. Larkey, and Otto Davis. In addition the department works closely with the departments of Engineering and Public Policy, Psychology, and Statistics, as well as the Tepper School of Business, Heinz College, and the Information Systems program. Many SDS faculty have joint appointments in these departments.
