The New Psychology of Nuclear Brinkmanship

Trending Globally: Politics and Policy

January 24th, 2023 marked an unsettling milestone: the Bulletin of the Atomic Scientists moved the ‘Doomsday Clock’ forward to 90 seconds to midnight – the closest it’s been to ‘Doomsday’ since the clock was established in 1947.

But what would it take for a nuclear weapon to actually be used in the world today? And if one was used, how would the rest of the world respond?

In this episode, the second in our limited series on the theory, policies, and practice of conflict escalation, you’ll hear from two experts rethinking how nuclear threats are understood and modeled.

Rose McDermott is a professor of International Affairs at the Watson Institute, and Reid Pauly is an assistant professor of Nuclear Security and Policy at Watson. Their paper “Decision-making Under Pressure: The Mechanisms and Psychology of Nuclear Brinkmanship” is the lead article in the current issue of International Security. In it, they reframe one of the most fundamental theories for understanding nuclear risks: nuclear “brinkmanship.” They highlight why conventional models of brinkmanship fail to fully explain how a nuclear crisis might unfold and explore what interventions are needed to prevent one from starting.
