In this episode of Machiavelli in the Ivory Tower, hosts Hanna and Sarah are joined by Rose McDermott, the David and Marianna Fisher University Professor of International Relations at Brown University. Together, they discuss Professor McDermott's recent article with Reid Pauly on the psychology of nuclear brinkmanship, the under-appreciated role of individuals in nuclear decision-making, and similarities and differences between the psychologies of political elites and the general population. They also consider more generally how and where political psychology and behavioral economics can enhance security studies by challenging normative assumptions about nuclear decision-making and shedding light on the ways that individuals actually behave in the face of uncertainty. Their conversation concludes with an exploration of the policy implications of Professor McDermott's findings and ways to more effectively bridge the gap between scholarship and practice.
