CSTEP's research assumes a broad definition of national security to include not only interal and external threats but also health, food, energy and environmental threats.
One big question CSTEP is working on is: How does a country identify the security challenges it may face and also persuade itself to learn about others that it could not, or would not normally foresee, because of their rarity, distance and constraints induced by bounded rationality? Often data for such analysis is either not available or cannot be shared. The Center is building scenarios of tehse threats and usign computational modeling techniques to anaylze them and present policy options.
