Her research draws on cognitive social psychology to explain foreign policy decision making, as in Origins of Containment: A Psychological Explanation. She is the author most recently of Anatomy of Mistrust: U.S.-Soviet Relations During the Cold War (1997), which uses social psychology to explain missed opportunities to mitigate U.S.-Soviet rivalry.
